Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to methods, devices and systems for spectrum resource sharing. Background Technology

[0002] Multi-operator core network (MOCN) is one of the network sharing methods proposed by the 3rd generation partnership project (3GPP). MOCN refers to a single wireless network that can simultaneously connect to the core network nodes of multiple networks, enabling multiple networks to share the same wireless network. For example, ... Figure 1 As shown, MOCN allows networks corresponding to Public Land Mobile Network (PLMN)-A and PLMN-B to share access network equipment through their respective independent core network equipment (such as core network equipment A in PLMN-A and core network equipment B in PLMN-B), and to share the serving cell of that access network equipment. The shared access network equipment simultaneously broadcasts the PLMN identifiers of all participating networks in the cell broadcast, and terminal devices access the network based on their corresponding PLMN identifier. It can be seen that MOCN greatly improves the sharing of spectrum resources (also referred to as spectrum or radio resources), equipment, transmission, and network management, and can minimize network construction costs.

[0003] Currently, to efficiently achieve 5G network coverage, rapidly develop 5G service capabilities, enhance the market competitiveness of 5G networks and services, and improve network efficiency and asset operation efficiency, many operators are adopting the MOCN (Multi-Operator Network) approach to co-build 5G networks. This involves sharing the access network, constructing the core network independently, and having two or more operators share 5G spectrum resources. However, improving the user experience for specific users (such as high-value users) or specific services (such as high-value services) in this network co-construction scheme remains a pressing issue. Summary of the Invention

[0004] This application provides a method, device, and system for spectrum resource sharing, which can improve the user experience of specific users (such as high-value users) or specific services (such as high-value services) in network co-construction schemes.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, a method for spectrum resource sharing is provided. The communication device executing the method can be a mobility management entity (MMI) or a module applied in the MMI, such as a chip or chip system. The following description uses the MMI as the executing entity as an example, including: the MMI determining that a first terminal device is permitted to occupy spectrum resources of a first network, the first terminal device being subscribed to a second network, and the MMI being a MMI within the second network; the MMI sending first indication information to an access network device, the first indication information indicating that the first terminal device is permitted to occupy spectrum resources of the first network, and the access network device being an access network device shared by the first and second networks. Based on this scheme, since the access network equipment can only allow the first terminal device to occupy the spectrum resources of the first network according to the first instruction information sent by the mobility management entity after the mobility management entity determines that the first terminal device is allowed to occupy the spectrum resources of the first network, it can avoid the spectrum resource congestion problem caused by all terminal devices or all services of terminal devices occupying the spectrum resources of different networks, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy the spectrum resources of different networks, the operator of this network may pay higher fees to the operators of other networks than to the operators of this network, thereby maximizing the commercial interests of the operator.

[0007] In conjunction with the first aspect above, in one possible implementation, the mobility management entity determines that the first terminal device is permitted to occupy spectrum resources of the first network, including: the mobility management entity determines that the first terminal device is permitted to occupy spectrum resources of the first network based on at least one of the first terminal device's subscription information, the first terminal device's access and mobility control policy information, or the second network's local policy information. For example, the mobility management entity (MMI) determines, based on the subscription information of the first terminal device, that the first terminal device is permitted to occupy spectrum resources of the first network; or, the MMI determines, based on access and mobility control policy information, that the first terminal device is permitted to occupy spectrum resources of the first network; or, the MMI determines, based on the local policy information of the second network, that the first terminal device is permitted to occupy spectrum resources of the first network; or, the MMI determines, based on the subscription information and access and mobility control policy information of the first terminal device, that the first terminal device is permitted to occupy spectrum resources of the first network; or, the MMI determines, based on the access and mobility control policy information and the local policy information of the second network, that the first terminal device is permitted to occupy spectrum resources of the first network; or, the MMI determines, based on the subscription information of the first terminal device, the local policy information of the second network, that the first terminal device is permitted to occupy spectrum resources of the first network; or, the MMI determines, based on the subscription information, access and mobility control policy information, and the local policy information of the second network, that the first terminal device is permitted to occupy spectrum resources of the first network.

[0008] In conjunction with the first aspect above, in one possible implementation, the subscription information of the first terminal device includes first information, which is used to characterize the first terminal device as being allowed to occupy spectrum resources of the first network.

[0009] In conjunction with the first aspect above, in one possible implementation, the access and mobility control policy information includes: second information, which is used to characterize the first terminal device being allowed to occupy spectrum resources of the first network within a first time period and / or a first location area and / or a first spectrum resource, wherein the first spectrum resource is the spectrum resource within the first network.

[0010] In conjunction with the first aspect above, in one possible implementation, the local policy information of the second network includes: third information, which is used to characterize the spectrum resources of the first network that terminal devices subscribed to the second network are allowed to occupy.

[0011] In conjunction with the first aspect described above, in one possible implementation, the spectrum resource sharing method provided in this application further includes: a mobility management entity sending a duration to an access network device that allows the first terminal device to occupy spectrum resources of the first network. Thus, when the duration for which the first terminal device occupies spectrum resources of the first network reaches the specified duration, the access network device can cease allowing the first terminal device to occupy spectrum resources of the first network, thereby achieving effective control over spectrum resource occupancy across different networks.

[0012] In conjunction with the first aspect described above, in one possible implementation, the spectrum resource sharing method provided in this application embodiment further includes: a mobility management entity receiving a second message from an access network device, the second message indicating that the spectrum resources of the second network to which the first terminal device is subscribed are insufficient; or, the second message requesting confirmation on whether the first terminal device is allowed to occupy the spectrum resources of the first network. In other words, this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first terminal device to occupy the spectrum resources of the first network based on service needs, thus making the scheme design more flexible.

[0013] Secondly, a method for spectrum resource sharing is provided. The communication device executing this method can be an access network device or a module applied in the access network device, such as a chip or chip system. The following description uses an access network device as the executing entity as an example, including: the access network device receiving first indication information from a mobility management entity, the first indication information indicating permission for a first terminal device to occupy spectrum resources of a first network, the first terminal device subscribing to a second network, the mobility management entity being a mobility management entity within the second network, and the access network device being an access network device shared by the first and second networks; the access network device, according to the first indication information, allowing the first terminal device to occupy spectrum resources of the first network. Based on this scheme, since the access network equipment can only allow the first terminal device to occupy the spectrum resources of the first network according to the first instruction information sent by the mobility management entity after the mobility management entity determines that the first terminal device is allowed to occupy the spectrum resources of the first network, it can avoid the spectrum resource congestion problem caused by all terminal devices or all services of terminal devices occupying the spectrum resources of different networks, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy the spectrum resources of different networks, the operator of this network may pay higher fees to the operators of other networks than to the operators of this network, thereby maximizing the commercial interests of the operator.

[0014] In conjunction with the second aspect, in one possible implementation, the spectrum resource sharing method provided in this application further includes: an access network device receiving a duration from a mobility management entity allowing the first terminal device to occupy spectrum resources of the first network; when the duration for which the first terminal device occupies spectrum resources of the first network reaches the specified duration, the access network device ceases to allow the first terminal device to occupy spectrum resources of the first network. Based on this scheme, effective control over spectrum resource occupancy across different networks can be achieved.

[0015] In conjunction with the second aspect described above, in one possible implementation, the spectrum resource sharing method provided in this application further includes: when the access network device determines that the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to a preset threshold, the access network device sends a second message to the mobility management entity, the second message indicating that the spectrum resources of the second network subscribed to by the first terminal device are insufficient; or, the second message requests confirmation as to whether the first terminal device is allowed to occupy the spectrum resources of the first network. In other words, this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first terminal device to occupy the spectrum resources of the first network based on service needs, thus making the scheme design more flexible.

[0016] Thirdly, a method for spectrum resource sharing is provided. The communication device executing this method can be a mobility management entity (MMI) or a module applied within the MMI, such as a chip or chip system. The following description uses the MMI as the executing entity as an example, including: the MMI determining that a first terminal device is allowed to occupy spectrum resources of a first network, the first terminal device being subscribed to a second network, and the MMI being a MMI within the second network; the MMI sending second indication information to an access network device, the second indication information indicating that the first terminal device's first service is allowed to occupy spectrum resources of the first network, the access network device being an access network device shared by the first and second networks. Based on this scheme, since the Mobility Management Entity (MME) determines that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the spectrum resources of the first network for the first service of the first terminal device according to the second instruction information sent by the MME. Therefore, on the one hand, it can avoid the spectrum resource congestion problem caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operator of this network, thereby maximizing the operator's commercial interests.

[0017] In conjunction with the third aspect above, in one possible implementation, the mobility management entity determines that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, including: the mobility management entity determines that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network based on at least one of the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network. For example, the Mobility Management Entity (MME) determines, based on the subscription information of the first terminal device, that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the MME determines, based on access and mobility control policy information, that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the MME determines, based on the local policy information of the second network, that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the MME determines, based on the subscription information and access and mobility control policy information of the first terminal device, that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the MME determines, based on the access and mobility control policy information and the local policy information of the second network, that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the MME determines, based on the subscription information of the first terminal device and the local policy information of the second network, that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the MME determines, based on the subscription information, access and mobility control policy information, and the local policy information of the second network, that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0018] In conjunction with the third aspect above, in one possible implementation, the subscription information of the first terminal device includes at least one of the following: first information, fourth information, or identification information of the first service; wherein the first information is used to indicate that the first terminal device is allowed to occupy the spectrum resources of the first network; and the fourth information is used to indicate that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0019] In conjunction with the third aspect above, in one possible implementation, the access and mobility control policy information includes: fifth information, which is used to characterize the first service of the first terminal device being allowed to occupy the spectrum resources of the first network in a first time period and / or a first location area and / or a first spectrum resource, wherein the first spectrum resource is the spectrum resource within the first network.

[0020] In conjunction with the third aspect above, in one possible implementation, the local policy information of the second network includes: sixth information, which is used to characterize the first service that allows a terminal device subscribed to the second network to occupy the spectrum resources of the first network.

[0021] In conjunction with the third aspect described above, in one possible implementation, the spectrum resource sharing method provided in this application further includes: a mobility management entity sending a duration to an access network device allowing the first terminal device's first service to occupy spectrum resources of the first network. Thus, when the duration for which the first terminal device's first service occupies spectrum resources of the first network reaches the specified duration, the access network device can cease occupying spectrum resources of the first network for the first terminal device's first service, thereby achieving effective control over spectrum resource occupancy across different networks.

[0022] In conjunction with the third aspect described above, in one possible implementation, the spectrum resource sharing method provided in this application embodiment further includes: the mobility management entity receiving a fourth message from the access network device, the fourth message indicating that the spectrum resources of the second network subscribed to by the first terminal device are insufficient; or, the fourth message requesting confirmation on whether the first terminal device or its first service is allowed to occupy the spectrum resources of the first network. Since this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first terminal device's first service to occupy the spectrum resources of the first network based on service requirements, the scheme design is more flexible.

[0023] Fourthly, a method for spectrum resource sharing is provided. The communication device executing this method can be an access network device or a module applied in the access network device, such as a chip or chip system. The following description uses an access network device as the executing entity as an example, including: the access network device receiving second indication information from a mobility management entity, the second indication information indicating that a first terminal device's first service is allowed to occupy spectrum resources of a first network; the first terminal device is subscribed to a second network; the mobility management entity is a mobility management entity within the second network; and the access network device is an access network device shared by the first and second networks; the access network device, according to the second indication information, occupies spectrum resources of the first network for the first terminal device's first service. Based on this scheme, since the Mobility Management Entity (MME) determines that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the spectrum resources of the first network for the first service of the first terminal device according to the second instruction information sent by the MME. Therefore, on the one hand, it can avoid the spectrum resource congestion problem caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operator of this network, thereby maximizing the operator's commercial interests.

[0024] In conjunction with the fourth aspect above, in one possible implementation, the spectrum resource sharing method provided in this application embodiment further includes: an access network device receiving a duration from a mobility management entity allowing the first terminal device's first service to occupy spectrum resources of the first network; when the duration for which the first terminal device's first service occupies spectrum resources of the first network reaches the specified duration, the access network device ceases to occupy spectrum resources of the first network for the first terminal device's first service. Based on this scheme, effective control over spectrum resource occupancy across different networks can be achieved.

[0025] In conjunction with the fourth aspect above, in one possible implementation, the spectrum resource sharing method provided in this application embodiment further includes: when the access network device determines that the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to a preset threshold, the access network device sends a fourth message to the mobility management entity, the fourth message indicating that the spectrum resources of the second network subscribed to by the first terminal device are insufficient; or, the fourth message is used to request confirmation on whether the first terminal device or its first service is allowed to occupy the spectrum resources of the first network. Since this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first terminal device's first service to occupy the spectrum resources of the first network based on service demand, the scheme design is more flexible.

[0026] Fifthly, a method for spectrum resource sharing is provided. The communication device executing the method can be a session management entity or a module applied in the session management entity, such as a chip or chip system. The following description uses a session management entity as the executing entity as an example, including: the session management entity determining that a first session of a first terminal device or a first quality of service (QoS) flow of the first session of the first terminal device is allowed to occupy spectrum resources of a first network; the first terminal device is subscribed to a second network; the session management entity is a session management entity within the second network; the session management entity sends third indication information to an access network device, the third indication information indicating that the first session of the first terminal device is allowed to occupy spectrum resources of the first network, or the third indication information indicating that the first QoS flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network; the access network device is an access network device shared by the first network and the second network. Based on this scheme, since the session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device according to the third indication information sent by the session management entity. Therefore, on the one hand, it can avoid the problem of spectrum resource congestion caused by occupying the spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services); on the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy the spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the commercial interests of the operator.

[0027] In conjunction with the fifth aspect described above, in one possible implementation, the third indication information indicates that the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network; the spectrum resource sharing method provided in this application embodiment further includes: a session management entity receiving a fifth message from a policy control entity, the fifth message including session policy information of the first terminal device. In other words, after the policy control entity determines whether to allow the first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network, the session management entity is triggered to determine whether to allow the first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network.

[0028] In a sixth aspect, a method for spectrum resource sharing is provided. The communication device executing the method can be a session management entity or a module applied in the session management entity, such as a chip or chip system. The following description uses a session management entity as the executing entity as an example, including: the session management entity receiving a sixth message indicating that the spectrum resources of the second network subscribed to by the first terminal device are insufficient; or, the sixth message requesting confirmation on whether to allow a first session of the first terminal device or a first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network, wherein the first terminal device is subscribed to the second network, and the session management entity is a session management entity within the second network; in response to the sixth message, the session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network; the session management entity sends third indication information to an access network device, the third indication information indicating that the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, or the third indication information indicating that the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, wherein the access network device is an access network device shared by the first network and the second network. Based on this scheme, since the session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the spectrum resources of the first network according to the third indication information sent by the session management entity. Therefore, on the one hand, it avoids the spectrum resource congestion problem caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it avoids the problem that the operator of this network may pay higher fees to the operator of the other network than to the operator of this network when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, thus maximizing the operator's commercial interests. Furthermore, since this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first session of the first terminal device or the first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network based on service needs, the scheme design is more flexible.

[0029] In conjunction with the sixth aspect above, in one possible implementation, the spectrum resource sharing method provided in this application further includes: a session management entity sending a duration to the access network device allowing the first session of the first terminal device or the first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network. Thus, when the duration for which the first session of the first terminal device or the first QoS flow of the first session of the first terminal device occupies the spectrum resources of the first network reaches the specified duration, the access network device can cease occupying the spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device, thereby achieving effective control over the spectrum resource occupancy of different networks.

[0030] In conjunction with the fifth or sixth aspect above, in one possible implementation, the session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, including: the session management entity determines, based on the subscription information and / or the session policy information of the first terminal device, that the first session of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the session management entity determines, based on the subscription information and / or the session policy information of the first terminal device, that the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network. For example, the session management entity can determine, based on the subscription information of the first terminal device, that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the session management entity can determine, based on the session policy information of the first terminal device, that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network; for example, the session management entity can determine, based on the subscription information and session policy information of the first terminal device, that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0031] In conjunction with the fifth or sixth aspect above, in one possible implementation, the service corresponding to the first QoS flow of the first session of the first terminal device is a first service; the subscription information of the first terminal device includes at least one of the following: first information, fourth information, or identification information of the first service; wherein, the first information is used to indicate that the first terminal device is allowed to occupy the spectrum resources of the first network; the fourth information is used to indicate that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0032] In conjunction with the fifth or sixth aspect, in one possible implementation, the service corresponding to the first QoS flow of the first session of the first terminal device is the first service; the session policy information of the first terminal device includes: seventh information; wherein the seventh information is used to characterize that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0033] In a seventh aspect, a method for spectrum resource sharing is provided. The communication device executing the method can be an access network device or a module applied in the access network device, such as a chip or chip system. The following description uses an access network device as the executing entity as an example, including: the access network device receiving third indication information from a session management entity, the third indication information indicating that a first session of a first terminal device is allowed to occupy spectrum resources of a first network, or the third indication information indicating that a first quality of service (QoS) flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network; the first terminal device is subscribed to a second network; the session management entity is a session management entity within the second network; and the access network device is an access network device shared by the first network and the second network; the access network device, according to the third indication information, occupies spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device. Based on this scheme, since the session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device according to the third indication information sent by the session management entity. Therefore, on the one hand, it can avoid the problem of spectrum resource congestion caused by occupying the spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services); on the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy the spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the commercial interests of the operator.

[0034] In conjunction with the seventh aspect above, in one possible implementation, before the access network device receives the third indication information from the session management entity, the spectrum resource sharing method provided in this application embodiment further includes: when the access network device determines that the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to a preset threshold, the access network device sends a sixth message to the mobility management entity, the sixth message indicating that the spectrum resources of the second network subscribed to by the first terminal device are insufficient; or, the sixth message is used to request confirmation on whether the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network. In other words, this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first session of the first terminal device or the first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network based on service requirements, thus making the scheme design more flexible.

[0035] In conjunction with the seventh aspect above, in one possible implementation, the spectrum resource sharing method provided in this application further includes: an access network device receiving from a session management entity a duration for which the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network; when the duration for which the first session of the first terminal device or the first QoS flow of the first session of the first terminal device occupies spectrum resources of the first network reaches the specified duration, the access network device no longer occupies spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device. Based on this scheme, effective control over spectrum resource occupancy in different networks can be achieved.

[0036] Eighthly, a method for spectrum resource sharing is provided. The communication device executing the method can be a mobility management entity (MMI) or a module applied in the MMI, such as a chip or chip system. The following description uses the MMI as the executing entity as an example, including: the MMI obtaining subscription information of a first terminal device, the subscription information of the first terminal device including information about a first spectrum resource, the first spectrum resource being spectrum resources of a first network that the first terminal device is allowed to occupy; the first terminal device subscribing to a second network; and the MMI being a MMI within the second network; the MMI sending the first spectrum resource information to an access network device, the access network device being an access network device shared by the first and second networks. Based on this scheme, since the Mobility Management Entity (MME) determines that the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the first spectrum resources for the first terminal device according to the first spectrum resource information sent by the MME. Therefore, on the one hand, it can avoid the spectrum resource congestion problem caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the operator's commercial interests.

[0037] Ninthly, a method for spectrum resource sharing is provided. The communication device executing the method can be an access network device or a module applied in the access network device, such as a chip or chip system. The following description, taking the access network device as the executing entity, includes: the access network device receiving information about a first spectrum resource from a mobility management entity, the first spectrum resource being a spectrum resource of a first network that a first terminal device is allowed to occupy; the first terminal device subscribing to a second network; the mobility management entity being a mobility management entity within the second network; and the access network device being an access network device shared by the first network and the second network; the access network device occupying the first spectrum resource for the first terminal device. Based on this scheme, since the Mobility Management Entity (MME) determines that the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the first spectrum resources for the first terminal device according to the first spectrum resource information sent by the MME. Therefore, on the one hand, it can avoid the spectrum resource congestion problem caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the operator's commercial interests.

[0038] In a tenth aspect, a method for spectrum resource sharing is provided. The communication device executing the method can be a mobility management entity (MMI) or a module applied in the MMI, such as a chip or chip system. The following description uses the MMI as the executing entity as an example, including: the MMI obtaining subscription information of a first terminal device, the subscription information of the first terminal device including information about second spectrum resources, the second spectrum resources being spectrum resources of a first network that the first terminal device is allowed to occupy for a first service; the first terminal device subscribing to a second network; and the MMI being a MMI within the second network; the MMI sending the second spectrum resource information to an access network device, the access network device being an access network device shared by the first network and the second network. Based on this scheme, since the Mobility Management Entity (MME) determines that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the second spectrum resources for the first service of the first terminal device according to the second spectrum resource information sent by the MME. Therefore, on the one hand, it can avoid the spectrum resource congestion problem caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the operator's commercial interests.

[0039] In conjunction with the tenth aspect described above, in one possible implementation, the information of the second spectrum resource includes a first identifier, wherein the first identifier is mapped to the identifier of the second spectrum resource and the identifier information of the first service. In other words, based on the first identifier, this application embodiment can determine the first service of the first terminal device that can occupy spectrum resources of the first network and the second spectrum resources of the first network that are allowed to be occupied.

[0040] In conjunction with the tenth aspect above, in one possible implementation, the information of the second spectrum resource includes: the identifier of the second spectrum resource and the identifier information of the first service.

[0041] Eleventhly, a method for spectrum resource sharing is provided. The communication device executing the method can be an access network device or a module applied in the access network device, such as a chip or chip system. The following description uses an access network device as the executing entity as an example, including: the access network device receiving information about a second spectrum resource from a mobility management entity, the second spectrum resource being spectrum resources of a first network that a first service of a first terminal device is allowed to occupy; the first terminal device is subscribed to a second network; the mobility management entity is a mobility management entity within the second network; and the access network device is an access network device shared by the first network and the second network; the access network device, based on the information about the second spectrum resource, allows the first service of the first terminal device to occupy the second spectrum resource. Based on this scheme, since the Mobility Management Entity (MME) determines that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the second spectrum resources for the first service of the first terminal device according to the second spectrum resource information sent by the MME. Therefore, on the one hand, it can avoid the spectrum resource congestion problem caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the operator's commercial interests.

[0042] In conjunction with the eleventh aspect above, in one possible implementation, the information of the second spectrum resource includes: a first identifier, wherein the first identifier has a mapping relationship with the identifier of the second spectrum resource and the identifier information of the first service. In other words, based on the first identifier, this application embodiment can determine the first service of the first terminal device that can occupy the spectrum resources of the first network and the second spectrum resources of the first network that are allowed to be occupied.

[0043] In conjunction with the eleventh aspect above, in one possible implementation, when the information of the second spectrum resource includes a first identifier, the access network device occupies the second spectrum resource for the first service of the first terminal device based on the information of the second spectrum resource, including: the access network device determining the second spectrum resource based on the first identifier and the mapping relationship between the first identifier and the identifier of the second spectrum resource; the access network device determining the first service based on the first identifier and the mapping relationship between the first identifier and the identifier information of the first service; and the access network device occupies the second spectrum resource for the first service of the first terminal device.

[0044] In conjunction with the eleventh aspect above, in one possible implementation, the information of the second spectrum resource includes: the identifier of the second spectrum resource and the identifier information of the first service.

[0045] In a twelfth aspect, a method for spectrum resource sharing is provided. The communication device executing the method can be a mobility management entity (MMI) or a module applied in the MMI, such as a chip or chip system. The following description uses the MMI as the executing entity as an example, including: the MMI obtaining first indication information, which indicates permission for a first terminal device to occupy spectrum resources of a first network; the first terminal device subscribing to a second network; and the MMI being a MMI within the second network. The MMI then sends first indication information to an access network device, which indicates permission for the first terminal device to occupy spectrum resources of the first network; the access network device is an access network device shared by the first and second networks. Based on this scheme, since the access network equipment can obtain the first instruction information from the mobility management entity and occupy the spectrum resources of the first network for the first terminal equipment according to the first instruction information, it can avoid the problem of spectrum resource congestion caused by occupying the spectrum resources of different networks for all terminal equipment or all services of terminal equipment, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy the spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the commercial interests of the operator.

[0046] In conjunction with the twelfth aspect above, in one possible implementation, the mobility management entity obtains the first indication information by: the mobility management entity obtaining the first indication information from the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network.

[0047] In a thirteenth aspect, a method for spectrum resource sharing is provided. The communication device executing the method can be a mobility management entity (MMI) or a module applied in the MMI, such as a chip or chip system. The following description uses the MMI as the executing entity as an example, including: the MMI obtaining second indication information, which indicates that a first terminal device is allowed to occupy spectrum resources of a first network for a first service; the first terminal device subscribing to a second network; and the MMI being a MMI within the second network. The MMI then sends the second indication information to an access network device, which is an access network device shared by the first and second networks. Based on this scheme, since the access network equipment can obtain the second instruction information from the mobility management entity and occupy the spectrum resources of the first network for the first service of the first terminal device according to the second instruction information, it can avoid the spectrum resource congestion problem caused by occupying the spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy the spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operator of this network, thereby maximizing the commercial interests of the operator.

[0048] In conjunction with the thirteenth aspect above, in one possible implementation, the mobility management entity obtains the second indication information by: the mobility management entity obtaining the second indication information from the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network.

[0049] In a fourteenth aspect, a method for spectrum resource sharing is provided. The communication device executing the method can be a session management entity or a module applied in the session management entity, such as a chip or chip system. The following description uses a session management entity as the executing entity as an example, including: the session management entity obtaining third indication information, which indicates that the first session of the first terminal device is allowed to occupy spectrum resources of the first network, or the third indication information indicates that the first QoS flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network; the first terminal device subscribes to a second network; and the session management entity is a mobility management entity within the second network. The session management entity sends the third indication information to an access network device, which is an access network device shared by the first and second networks. Based on this scheme, since the access network device can obtain third indication information from the session management entity and occupy spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device according to the third indication information, it can avoid the problem of spectrum resource congestion caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the commercial interests of the operator.

[0050] In conjunction with the fourteenth aspect above, in one possible implementation, the session management entity obtains the third indication information by: the session management entity obtaining the first indication information from the subscription information of the first terminal device or the session policy information of the first terminal device.

[0084] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can represent A or B. "And / or" in this application is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone, where A and B can be singular or plural. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple. Furthermore, to facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that "first" and "second" are not necessarily different. Meanwhile, in the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is being used as an example, illustration, or description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0085] Furthermore, the network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0086] In network co-construction schemes, if spectrum resources from other networks are unconditionally occupied for all terminal devices or all services of terminal devices, on the one hand, it will lead to insufficient spectrum resources and cause service congestion on some terminal devices, resulting in a deterioration in the experience of specific users (such as high-value users) or specific services (such as high-value services); on the other hand, since spectrum resources from other networks are paid for, when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources from other networks, the fees paid by the operator of this network to the operators of other networks may be higher than the fees paid to the operator of this network, which will not be in the commercial interests of the operator.

[0087] like Figure 2 The diagram illustrates a communication system 20 provided in this embodiment of the application. The communication system 20 includes a mobility management entity 201 and an access network device 202. The mobility management entity 201 is a mobility management entity within a second network, and the access network device 202 is an access network device shared by the first and second networks. The mobility management entity 201 and the access network device 202 can communicate directly or through forwarding from other devices; this embodiment of the application does not specifically limit this communication method.

[0088] In one possible implementation, the mobility management entity 201, after determining that the first terminal device is permitted to occupy spectrum resources of the first network, sends a first indication message to the access network device 202. The first indication message indicates that the first terminal device is permitted to occupy spectrum resources of the first network. The first terminal device is subscribed to a second network. The access network device 202 receives the first indication message from the mobility management entity and, based on the first indication message, allows the first terminal device to occupy spectrum resources of the first network. The specific implementation and related technical effects of this scheme will be described in detail in subsequent method embodiments, and will not be repeated here.

[0089] In another possible implementation, the Mobility Management Entity 201, after determining that the first service of the first terminal device is allowed to occupy spectrum resources of the first network, sends a second indication message to the Access Network Device 202. The second indication message indicates that the first service of the first terminal device is allowed to occupy spectrum resources of the first network, and the first terminal device subscribes to the second network. The Access Network Device 202 receives the second indication message from the Mobility Management Entity and, based on the second indication message, allows the first terminal device to occupy spectrum resources of the first network for its first service. The specific implementation and related technical effects of this scheme will be described in detail in subsequent method embodiments, and will not be repeated here.

[0090] In another possible implementation, the Mobility Management Entity 201 is used to obtain the subscription information of the first terminal device. The subscription information of the first terminal device includes information about a first spectrum resource, which is the spectrum resource of a first network that the first terminal device is allowed to occupy. The first terminal device subscribes to a second network. The Mobility Management Entity 201 is also used to send the first spectrum resource information to the Access Network Device 202. The Access Network Device 202 is used to receive the first spectrum resource information from the Mobility Management Entity and to allow the first terminal device to occupy the first spectrum resource. The specific implementation and related technical effects of this scheme will be described in detail in subsequent method embodiments, and will not be repeated here.

[0091] In another possible implementation, the Mobility Management Entity 201 is used to obtain the subscription information of the first terminal device. The subscription information of the first terminal device includes information about second spectrum resources. The second spectrum resources are spectrum resources of the first network that the first terminal device's first service is allowed to occupy. The first terminal device subscribes to the second network. The Mobility Management Entity 201 is also used to send the second spectrum resource information to the access network device 202. The access network device 202 is used to receive the second spectrum resource information from the Mobility Management Entity and, based on the second spectrum resource information, allocate the second spectrum resources for the first terminal device's first service. The specific implementation and related technical effects of this scheme will be described in detail in subsequent method embodiments, and will not be repeated here.

[0092] like Figure 3 As shown, another communication system 30 provided in this application embodiment includes a session management entity 301 in a second network and an access network device 302 in a first network. The session management entity 301 and the access network device 302 can communicate directly or through forwarding from other devices; this application embodiment does not specifically limit this communication.

[0093] In this system, the session management entity 301, after determining that the first session of the first terminal device or the first quality of service (QoS) flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network, sends third indication information to the access network device 302. The third indication information indicates that the first session of the first terminal device is allowed to occupy spectrum resources of the first network, or that the first QoS flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network, and the first terminal device subscribes to the second network. The access network device 302 receives the third indication information from the session management entity and, based on the third indication information, allows the first session of the first terminal device or the first QoS flow of the first session of the first terminal device to occupy spectrum resources of the first network. The specific implementation and related technical effects of this scheme will be described in detail in subsequent method embodiments and will not be repeated here.

[0094] It should be noted that in the embodiments of this application, the first terminal device signing up for the second network can also be understood as the first terminal device's home network being the second network. This will be explained uniformly here and will not be repeated below.

[0095] It should be noted that in this embodiment, the first network and the second network are different networks sharing the same wireless access network. That is, the first network and the second network are different networks. The first network and the second network can correspond to the same operator or different operators; this embodiment does not specifically limit this. For example, the first network is a first PLMN network, and the second network is a second PLMN network (such as a telecommunications network). The first PLMN network can be, for example, a China Unicom network, and the second PLMN network can be, for example, a China Telecom network; or, the first PLMN network is Beijing Mobile, and the second PLMN network is Hebei Mobile. Alternatively, for example, the first network is a public network, and the second network is a private network; or, the first network is a private network, and the second network is a public network; or, the first network is a first public network, and the second network is a second public network; or, the first network is a first private network, and the second network is a second private network, etc. This is uniformly stated here, and this embodiment does not specifically limit this.

[0096] Optional, Figure 2 The communication system 20 shown or Figure 3 The communication system 30 shown can be applied to the 5G network currently under discussion, or to other networks in the future, etc. This application embodiment does not specifically limit it.

[0097] For example, the communication system 20 shown in Figure 2 or Figure 3 Taking the communication system 30 shown as an example, which is applicable to the currently discussed 5G network, then as follows... Figure 4 As shown, the network element or entity corresponding to the above-mentioned access network equipment can be the RAN equipment in the 5G network; the network element or entity corresponding to the above-mentioned mobility management entity can be the AMF in the 5G network; and the network element or entity corresponding to the above-mentioned session management entity can be the SMF in the 5G network.

[0098] In addition, such as Figure 4As shown, 5G networks can also include user plane functions (UPF), authentication server functions (AUSF), network slice selection functions (NSSF), network exposure functions (NEF), network function repository functions (NRF), policy control functions (PCF), unified data management (UDM), unified data repository (UDR), or application functions (AF). Specifically, terminal devices access the 5G network through RAN equipment. The terminal device communicates with the AMF through the N1 interface (N1); the RAN equipment communicates with the AMF through the N2 interface (N2); the RAN equipment communicates with the UPF through the N3 interface (N3); the SMF communicates with the UP through the N4 interface (N4); and the UPF accesses the data network through the N6 interface (N6). Furthermore, Figure 4 The control plane functions shown, such as AUSF, AMF, SMF, NSSF, NEF, NRF, PCF, UDM, UDR, or AF, interact using service-oriented interfaces. For example, the service-oriented interface provided by AUSF is Nausf; AMF is Namf; SMF is Nsmf; NSSF is Nnssf; NEF is Nnef; NRF is Nnrf; PCF is Npcf; UDM is Nudm; UDR is Nudr; and AF is Naf. For relevant functional and interface descriptions, please refer to the 5G system architecture diagram in the 23501 standard; they will not be elaborated upon here.

[0099] Optionally, the first terminal device in this embodiment is a device with wireless transceiver capabilities, such as a terminal or a chip that can be used in a terminal. The first terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water (such as a ship); and it can also be deployed in the air (such as on an airplane, balloon, or satellite). The terminal can be a user equipment (UE), access terminal, terminal unit, terminal station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, terminal agent, or terminal device in a 5G network or a future evolved PLMN. Access terminals can be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices or wearable devices, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc. Terminals can be mobile or fixed.

[0100] Optionally, the access network device in this application embodiment can be any communication device with wireless transceiver capabilities used for communicating with terminal devices. This access network device includes, but is not limited to: evolved node B (eNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or TRP in a wireless fidelity (WIFI) system. The access network device can also be a RAN device in a 5G system, which may include, for example, a gNB, TRP, or TP, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system. Furthermore, the RAN device can also be a network node constituting a gNB or TP, such as a BBU, or a distributed unit (DU).

[0101] In some deployments, a gNB may include a centralized unit (CU) and a dedicated unit (DU). Additionally, a gNB may include an active antenna unit (AAU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU handles non-real-time protocols and services, implementing radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions. The DU handles physical layer protocols and real-time services, implementing radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. The AAU implements some physical layer processing functions, radio frequency processing, and active antenna-related functions. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU. It is understandable that access network equipment can be one or more of the following: CU node, DU node, and AAU node.

[0116] The method for spectrum resource sharing provided in the embodiments of this application will now be described with reference to the accompanying drawings.

[0117] like Figure 6 As shown in the figure, a method for spectrum resource sharing provided in an embodiment of this application is described below.

[0118] S601, The mobility management entity determines that the first terminal device is permitted to occupy the spectrum resources of the first network.

[0119] The first terminal device is subscribed to the second network. The mobility management entity is the mobility management entity within the second network.

[0120] In one possible implementation, step S601 includes: the mobility management entity determining, based on at least one of the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network, the scope of spectrum resources of the first terminal device that are permitted to be occupied by the first terminal device.

[0121] Optionally, the subscription information of the first terminal device includes first information, which is used to characterize the first terminal device's permission to occupy spectrum resources of the first network.

[0122] For example, the first information mentioned above can be represented by one bit. For instance, "1" indicates that the first terminal device is allowed to occupy the spectrum resources of the first network, and "0" indicates that the first terminal device is not allowed to occupy the spectrum resources of the first network; or, "0" indicates that the first terminal device is allowed to occupy the spectrum resources of the first network, and "1" indicates that the first terminal device is not allowed to occupy the spectrum resources of the first network. This application embodiment does not make specific limitations in this regard.

[0123] Optionally, the access and mobility control policy information of the first terminal device includes: second information, which is used to characterize the first terminal device being allowed to occupy spectrum resources of the first network within a first time period and / or a first location area and / or a first spectrum resource, wherein the first spectrum resource is the spectrum resource within the first network.

[0124] For example, the second information may include information about a first time period during which the first terminal device is allowed to occupy spectrum resources of the first network and / or information about a first location area and / or first spectrum resources.

[0125] Optionally, the local policy information of the second network includes: third information, which is used to characterize the spectrum resources of the first network that terminal devices subscribed to the second network are allowed to occupy. For example, if a first terminal device subscribes to the second network, the mobility management entity can determine, based on the local policy information of the second network, the spectrum resources of the first network that the first terminal device is allowed to occupy.

[0126] For example, the aforementioned third information can be represented by one bit. For instance, "1" indicates that terminal devices subscribed to the second network are allowed to occupy the spectrum resources of the first network, and "0" indicates that terminal devices subscribed to the second network are not allowed to occupy the spectrum resources of the first network; or, "0" indicates that terminal devices subscribed to the second network are allowed to occupy the spectrum resources of the first network, and "1" indicates that terminal devices subscribed to the second network are not allowed to occupy the spectrum resources of the first network. This application embodiment does not specifically limit this.

[0127] For example, when the subscription information of the first terminal device includes first information, the mobility management entity can determine, based on the subscription information of the first terminal device, the spectrum resources of the first network that the first terminal device is allowed to occupy. Alternatively, when the access and mobility control policy information of the first terminal device includes second information, the mobility management entity can determine, based on the access and mobility control policy information of the first terminal device, the spectrum resources of the first network that the first terminal device is allowed to occupy within a first time period and / or a first location area and / or a first spectrum resource. Alternatively, when the local policy information of the second network includes third information, the mobility management entity can determine, based on the local policy information of the second network, the spectrum resources of the first network that a terminal device subscribed to the second network is allowed to occupy. Since the first terminal device is subscribed to the second network, the mobility management entity can determine that the spectrum resources of the first network that the first terminal device is allowed to occupy. Alternatively, when the subscription information of the first terminal device includes the first information, and the access and mobility control policy information of the first terminal device includes the second information, the mobility management entity can determine, based on the subscription information of the first terminal device, the permitted spectrum resources of the first network for the first terminal device to occupy. Further, the mobility management entity can determine, based on the access and mobility control policy information of the first terminal device, the permitted spectrum resources of the first network for the first terminal device to occupy within a first time period and / or a first location area and / or a first spectrum resource. Alternatively, when the subscription information of the first terminal device includes the first information, and the local policy information of the second network includes the third information, the mobility management entity can determine, based on the local policy information of the second network, the permitted spectrum resources of the first network for the terminal device on the second network. Further, the mobility management entity can determine, based on the subscription information of the first terminal device, the permitted spectrum resources of the first network for the first terminal device to occupy. Alternatively, when the access and mobility control policy information of the first terminal device includes the second information, and the local policy information of the second network includes the third information, the mobility management entity can determine, based on the local policy information of the second network, the permitted spectrum resources of the first network for the terminal device on the second network. Since the first terminal device has subscribed to the second network, the mobility management entity can further determine, based on the access and mobility control policy information of the first terminal device, the permitted spectrum resources of the first network for the first terminal device to occupy within a first time period and / or a first location area and / or a first spectrum resource. Alternatively, when the subscription information of the first terminal device includes first information, the access and mobility control policy information of the first terminal device includes second information, and the local policy information of the second network includes third information, the mobility management entity can determine, based on the local policy information of the second network, the permitted spectrum resources of the first network for the terminal device on the second network. Furthermore, the mobility management entity can determine, based on the subscription information of the first terminal device, the permitted spectrum resources of the first network for the first terminal device.Furthermore, the mobility management entity can determine, based on the access and mobility control policy information of the first terminal device, the spectrum resources of the first network that the first terminal device is allowed to occupy within the first time period and / or the first location area and / or the first spectrum resources.

[0128] For example, when the local policy information of the second network includes third information, and the subscription information of the first terminal device includes information indicating that the first terminal device is not allowed to occupy spectrum resources of the first network, the mobility management entity can determine, based on the subscription information of the first terminal device and the local policy information of the second network, that the first terminal device is not allowed to occupy spectrum resources of the first network. Alternatively, when the local policy information of the second network includes third information, the subscription information of the first terminal device includes first information, and the current location of the first terminal device does not meet the location area information requirements in the access and mobility control policy information of the first terminal device (e.g., the location area information allows the first terminal device to occupy spectrum resources of the first network within a first location area, but the first terminal device is not currently within the first location area; or, the location area information disallows the first terminal device to occupy spectrum resources of the first network in an area outside the first location area, but the first terminal device is currently within that location area), the mobility management entity can determine, based on the subscription information of the first terminal device, the local policy information of the second network, and the access and mobility control policy information of the first terminal device, that the first terminal device is not allowed to occupy spectrum resources of the first network.

[0129] S602, The Mobility Management Entity sends a first message to the Access Network Equipment. Correspondingly, the Access Network Equipment receives the first message from the Mobility Management Entity.

[0130] The first message includes a first instruction, which indicates that the first terminal device is permitted to occupy the spectrum resources of the first network. The access network device is an access network device shared by the first network and the second network.

[0131] S603. The access network device occupies the spectrum resources of the first network for the first terminal device according to the first instruction information.

[0132] It should be noted that the access network device occupying the spectrum resources of the first network for the first terminal device can be understood as the access network device occupying the spectrum resources of the first network for all services of the first terminal device, or it can be understood as the access network device transmitting all service data of the first terminal device through the spectrum resources of the first network. This is explained in a unified manner here and will not be repeated below.

[0133] For example, assuming the spectrum resources of the first network are 100MHz between 3.5-3.6GHz, and the spectrum resources of the second network subscribed to by the first terminal device are 100MHz between 3.4-3.5GHz, then when the access network device determines that only 20MHz of the available spectrum resources of the second network subscribed to by the first terminal device are left, which cannot meet the service needs of the first terminal device (e.g., requiring 40MHz of spectrum resources), the access network device can occupy the spectrum resources of the first network to meet the service needs of the first terminal device.

[0134] In one possible implementation, after the access network device has occupied the remaining available spectrum resources of the second network (e.g., 20MHz of available spectrum resources between 3.4-3.5G) for the first terminal device, it can continue to occupy spectrum resources of the first network (e.g., 20MHz of available spectrum resources between 3.5-3.6G) for the first terminal device.

[0135] Alternatively, in another possible implementation, although the spectrum resources of the first network are 100MHz between 3.4G and 3.5G, and the spectrum resources of the second network are also 100MHz between 3.4G and 3.5G, under network sharing conditions, the first network and the second network can dynamically occupy any 100MHz of spectrum resources between 3.4G and 3.6G. In this case, the access network device can occupy a portion of the remaining available spectrum resources of the second network and a portion of the spectrum resources of the first network for the first terminal device. For example, the access network device can occupy 10MHz of spectrum resources of the second network (e.g., 10MHz of spectrum resources out of the 20MHz available spectrum resources between 3.4G and 3.5G) and 30MHz of spectrum resources of the first network (e.g., 30MHz of spectrum resources out of the 100MHz spectrum resources between 3.5G and 3.6G) for the first terminal device.

[0136] It should be noted that the access network device may allocate the spectrum resources of the first network occupied by the first terminal device to the first terminal device and / or other terminal devices of the second network. If the access network device allocates the spectrum resources of the first network occupied by the first terminal device to other terminal devices of the second network, then the access network device may allocate a corresponding number of spectrum resources of the second network allocated to other terminal devices of the second network to the first terminal device. This application embodiment does not limit how the access network device allocates the spectrum resources of the first network and the spectrum resources of the second network occupied by the first terminal device. For example, continuing the above example, if the spectrum resources of the first network occupied to meet the service needs of the first terminal device (e.g., 20MHz of spectrum resources out of 100MHz spectrum resources between 3.5-3.6G) are allocated to other terminal devices of the second network, then the access network device may allocate the 20MHz spectrum resources of the second network allocated to other terminal devices of the second network to the first terminal device, that is, allocate 40MHz of spectrum resources between 3.4-3.5G to the first terminal device. Alternatively, following the example above, if a portion of the spectrum resources (e.g., 10MHz of spectrum resources) of the first network (e.g., 30MHz of spectrum resources out of 100MHz spectrum resources between 3.5-3.6G) used to meet the service needs of the first terminal device is allocated to the first terminal device, and a portion of the spectrum resources (e.g., 20MHz of spectrum resources) is allocated to other terminal devices in the second network, then the access network device can allocate the 20MHz spectrum resources of the second network allocated to other terminal devices in the second network to the first terminal device, that is, allocate the 30MHz spectrum resources between 3.4-3.5G to the first terminal device.

[0137] Optionally, the spectrum resource sharing method provided in this application embodiment further includes: when the access network device determines that the spectrum resource demand of the second network subscribed by the first terminal device is greater than or equal to a preset threshold, the access network device sends a second message to the mobility management entity, the second message indicating that the spectrum resources of the second network subscribed by the first terminal device are insufficient; or, the second message requests confirmation on whether the first terminal device is allowed to occupy the spectrum resources of the first network. Furthermore, before step S601, the mobility management entity receives the second message from the access network device and determines whether the first terminal device is allowed to occupy the spectrum resources of the first network. Since this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first terminal device to occupy the spectrum resources of the first network based on service requirements, the scheme design is more flexible.

[0138] Optionally, the first message in this embodiment of the application further includes the duration for which the first terminal device is allowed to occupy the spectrum resources of the first network. Thus, when the duration for which the first terminal device occupies the spectrum resources of the first network reaches this duration, the access network device can cease allowing the first terminal device to occupy the spectrum resources of the first network, thereby achieving effective control over the occupancy of spectrum resources in different networks.

[0139] Based on the spectrum resource sharing method provided in this application embodiment, since the access network device can only allow the first terminal device to occupy the spectrum resources of the first network according to the first instruction information sent by the mobility management entity after the mobility management entity determines that the first terminal device is allowed to occupy the spectrum resources of the first network, on the one hand, it can avoid the problem of spectrum resource congestion caused by all terminal devices or all services of terminal devices occupying spectrum resources of different networks, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services); on the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the commercial interests of the operator.

[0140] The actions of the movement management entity in steps S601 to S603 above can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the mobility management entity to execute the above steps S601 to S603. The actions of the access network device can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the access network device to execute, and this embodiment does not impose any restrictions on this.

[0141] It should be noted that, Figure 6 The illustrated embodiment uses the example of a mobility management entity (MMI) sending first indication information to an access network device after determining that the first terminal device is permitted to occupy spectrum resources of the first network. Alternatively, in this embodiment, the MMI may obtain the first indication information and send it to the access network device; this embodiment does not specifically limit this. Obtaining the first indication information includes: the MMI obtaining the first indication information from the first terminal device's subscription information, the first terminal device's access and mobility control policy information, or the local policy information of the second network. Other related descriptions can be found in [reference needed]. Figure 6 The embodiments shown will not be described in detail here.

[0142] like Figure 7As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0143] S701, The Mobility Management Entity determines that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0144] The first terminal device is subscribed to the second network. The mobility management entity is the mobility management entity within the second network.

[0145] For example, in the embodiments of this application, the first service of the first terminal device may include vehicle networking service, terminal device positioning service, IP multimedia subsystem (IMS) service, or high-value services such as Migu Video.

[0146] In one possible implementation, step S701 includes: the mobility management entity determining, based on at least one of the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network, the spectrum resources of the first network that the first service of the first terminal device is allowed to occupy.

[0147] Optionally, the subscription information of the first terminal device may include at least one of the following: first information, fourth information, or identification information of the first service of the first terminal device. The first information is used to indicate that the first terminal device is permitted to occupy spectrum resources of the first network. The fourth information is used to indicate that the first service of the first terminal device is permitted to occupy spectrum resources of the first network.

[0148] The relevant description of the first piece of information above can be found here. Figure 6 The embodiments shown will not be described in detail here.

[0149] For example, the aforementioned fourth information can be represented by one bit. For instance, "1" indicates that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, and "0" indicates that the first service of the first terminal device is not allowed to occupy the spectrum resources of the first network; or, "0" indicates that the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, and "1" indicates that the first service of the first terminal device is not allowed to occupy the spectrum resources of the first network. This application embodiment does not specifically limit this.

[0150] In this embodiment, the identification information of the first service is used to uniquely identify the first service. For example, when the first service is a vehicle-to-everything (V2X) service, the identification information of the first service may be, for example, the network slice selection assistance information (NSSAI) corresponding to the V2X service, or the NSSAI and data network name (DNN) corresponding to the V2X service. Alternatively, when the first service is an IMS service, the identification information of the first service may be, for example, the NSSAI corresponding to the IMS service, or the NSSAI and DNN corresponding to the IMS service.

[0151] Optionally, the access and mobility control policy information of the first terminal device may include, for example, a fifth piece of information, which is used to characterize the first service of the first terminal device being allowed to occupy the spectrum resources of the first network within a first time period and / or a first location area and / or a first spectrum resource, wherein the first spectrum resource is the spectrum resource within the first network.

[0152] For example, the fifth information mentioned above may include information about a first time period during which the first service of the first terminal device is allowed to occupy spectrum resources of the first network and / or information about the first location area and / or the first spectrum resources.

[0153] Optionally, the local policy information of the second network may include, for example, a sixth piece of information, which is used to characterize the first service that allows a terminal device subscribed to the second network to occupy spectrum resources of the first network.

[0154] For example, the sixth piece of information can be represented by one bit. For instance, "1" indicates that the first service of a terminal device subscribed to the second network is allowed to occupy the spectrum resources of the first network, and "0" indicates that the first service of a terminal device subscribed to the second network is not allowed to occupy the spectrum resources of the first network; or, "0" indicates that the first service of a terminal device subscribed to the second network is allowed to occupy the spectrum resources of the first network, and "1" indicates that the first service of a terminal device subscribed to the second network is not allowed to occupy the spectrum resources of the first network. This application embodiment does not specifically limit this.

[0155] For example, when the subscription information of the first terminal device includes the fourth information, the mobility management entity can determine, based on the subscription information of the first terminal device, the permitted first service of the first terminal device to occupy the spectrum resources of the first network. Alternatively, when the access and mobility control policy information of the first terminal device includes the fifth information, the mobility management entity can determine, based on the access and mobility control policy information of the first terminal device, the permitted first service of the first terminal device to occupy the spectrum resources of the first network within a first time period and / or a first location area and / or a first spectrum resource. Alternatively, when the local policy information of the second network includes the sixth information, the mobility management entity can determine, based on the local policy information of the second network, the permitted first service of a terminal device subscribed to the second network to occupy the spectrum resources of the first network. Since the first terminal device is subscribed to the second network, the mobility management entity can determine the permitted first service of the first terminal device to occupy the spectrum resources of the first network. Alternatively, when the subscription information of the first terminal device includes first information, and the access and mobility control policy information of the first terminal device includes fifth information, the mobility management entity can determine, based on the subscription information of the first terminal device, the permitted spectrum resources of the first network for the first terminal device to occupy. Further, the mobility management entity can determine, based on the access and mobility control policy information of the first terminal device, the permitted spectrum resources of the first network for the first service of the first terminal device to occupy within a first time period and / or a first location area and / or the first spectrum resources. Alternatively, when the subscription information of the first terminal device includes the identifier information of the first service of the first terminal device, and the local policy information of the second network includes sixth information, the mobility management entity can determine, based on the local policy information of the second network, the permitted spectrum resources of the first network for the first service of the terminal device in the second network to occupy. Further, the mobility management entity can determine, based on the subscription information of the first terminal device, the permitted spectrum resources of the first network for the first service of the first terminal device to occupy. Alternatively, when the access and mobility control policy information of the first terminal device includes fifth information, and the local policy information of the second network includes sixth information, the mobility management entity can determine, based on the local policy information of the second network, the permitted spectrum resources of the first network for the first service of the terminal device in the second network to occupy. Since the first terminal device has subscribed to the second network, the mobility management entity can further determine, based on the access and mobility control policy information of the first terminal device, the permitted first service of the first terminal device to occupy the spectrum resources of the first network within a first time period and / or a first location area and / or a first spectrum resource. Alternatively, when the subscription information of the first terminal device includes the identification information of the first service, the access and mobility control policy information of the first terminal device includes the fifth information, and the local policy information of the second network includes the sixth information, the mobility management entity can determine, based on the local policy information of the second network, the permitted first service of the terminal device on the second network to occupy the spectrum resources of the first network.Furthermore, the mobility management entity can determine, based on the subscription information of the first terminal device, the spectrum resources of the first network that the first service of the first terminal device is allowed to occupy. Furthermore, the mobility management entity can determine, based on the access and mobility control policy information of the first terminal device, the spectrum resources of the first network that the first service of the first terminal device is allowed to occupy within a first time period and / or a first location area and / or a first spectrum resource.

[0156] For example, when the local policy information of the second network includes the sixth information, and the subscription information of the first terminal device includes information indicating that the first service of the first terminal device is not allowed to occupy the spectrum resources of the first network, the mobility management entity can determine, based on the subscription information of the first terminal device and the local policy information of the second network, that the first service of the first terminal device is not allowed to occupy the spectrum resources of the first network. Alternatively, when the local policy information of the second network includes the sixth information, the subscription information of the first terminal device includes the fourth information, and the current location of the first terminal device does not meet the location area information requirements in the access and mobility control policy information of the first terminal device (e.g., the location area information allows the first service of the first terminal device to occupy the spectrum resources of the first network within a first location area, but the first terminal device is not currently within the first location area; or, the location area information disallows the first service of the first terminal device to occupy the spectrum resources of the first network in an area outside the first location area, but the first terminal device is currently within that location area), the mobility management entity can determine, based on the subscription information of the first terminal device, the local policy information of the second network, and the access and mobility control policy information of the first terminal device, that the first service of the first terminal device is not allowed to occupy the spectrum resources of the first network.

[0157] S702, The Mobility Management Entity sends a third message to the Access Network Equipment. Correspondingly, the Access Network Equipment receives the third message from the Mobility Management Entity.

[0158] The third message includes a second instruction, which indicates that the first terminal device's first service is permitted to occupy spectrum resources of the first network. The access network device is a shared access network device between the first and second networks.

[0159] S703. The access network device occupies the spectrum resources of the first network for the first service of the first terminal device according to the second instruction information.

[0160] It should be noted that the first service of the first terminal device occupying the spectrum resources of the first network can be understood as the access network device being able to transmit the data of the first service of the first terminal device through the spectrum resources of the first network. This is explained here and will not be repeated below.

[0161] For example, assuming the spectrum resources of the first network are 100MHz between 3.5-3.6GHz, and the spectrum resources of the second network subscribed to by the first terminal device are 100MHz between 3.4-3.5GHz, then when the access network device determines that only 20MHz of the available spectrum resources of the second network subscribed to by the first terminal device are left, which cannot meet the needs of the first terminal device's first service (e.g., requiring 40MHz of spectrum resources), the access network device can occupy the spectrum resources of the first network to meet the needs of the first terminal device's first service.

[0162] In one possible implementation, after the access network device has occupied the remaining available spectrum resources of the second network (e.g., 20MHz of available spectrum resources between 3.4-3.5G) for the first service of the first terminal device, it can continue to occupy the spectrum resources of the first network (e.g., 20MHz of available spectrum resources between 3.5-3.6G) for the first service of the first terminal device.

[0163] Alternatively, in another possible implementation, although the spectrum resources of the first network are 100MHz between 3.4G and 3.5G, and the spectrum resources of the second network are also 100MHz between 3.4G and 3.5G, under network sharing conditions, the first network and the second network can dynamically occupy any 100MHz of spectrum resources between 3.4G and 3.6G. In this case, the access network device can occupy a portion of the remaining available spectrum resources of the second network and a portion of the spectrum resources of the first network for the first service of the first terminal device. For example, the access network device can occupy 10MHz of spectrum resources of the second network (e.g., 10MHz of spectrum resources out of the 20MHz available spectrum resources between 3.4G and 3.5G) and 30MHz of spectrum resources of the first network (e.g., 30MHz of spectrum resources out of the 100MHz spectrum resources between 3.5G and 3.6G) for the first service of the first terminal device.

[0164] It should be noted that the access network device may allocate the spectrum resources of the first network occupied by the first service of the first terminal device to the first service of the first terminal device and / or other services of the first terminal device and / or other terminal devices of the second network. If the access network device allocates the spectrum resources of the first network occupied by the first service of the first terminal device to other services of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate a corresponding amount of spectrum resources of the second network allocated to the other services of the first terminal device and / or other terminal devices of the second network to the first terminal device. The embodiments of this application do not limit how the access network device allocates the spectrum resources of the first network occupied by the first service of the first terminal device and the spectrum resources of the second network. For example, continuing the above example, if the spectrum resources of the first network occupied to meet the needs of the first service of the first terminal device (e.g., 20MHz of spectrum resources out of 100MHz spectrum resources between 3.5-3.6G) are allocated to other services of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate the 20MHz spectrum resources of the second network allocated to other services of the first terminal device and / or other terminal devices of the second network to the first service of the first terminal device, that is, allocate the 40MHz spectrum resources between 3.4-3.5G to the first service of the first terminal device. Alternatively, following the example above, if a portion of the spectrum resources (e.g., 10MHz of spectrum resources) of the first network (e.g., 30MHz of spectrum resources out of 100MHz spectrum resources between 3.5-3.6G) used to meet the needs of the first service of the first terminal device are allocated to the first service of the first terminal device, and a portion of the spectrum resources (e.g., 20MHz of spectrum resources) are allocated to other services of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate the 20MHz spectrum resources of the second network allocated to the other services of the first terminal device and / or other terminal devices of the second network to the first service of the first terminal device, that is, the 30MHz spectrum resources between 3.4-3.5G are allocated to the first service of the first terminal device.

[0165] Optionally, the spectrum resource sharing method provided in this application embodiment further includes: when the access network device determines that the spectrum resource demand of the second network subscribed by the first terminal device is greater than or equal to a preset threshold, the access network device sends a fourth message to the mobility management entity, the fourth message indicating that the spectrum resources of the second network subscribed by the first terminal device are insufficient; or, the second message is used to request confirmation on whether the first terminal device or its first service is allowed to occupy the spectrum resources of the first network. Furthermore, before step S701, the mobility management entity receives the fourth message from the access network device and determines whether the first service of the first terminal device is allowed to occupy the spectrum resources of the first network. Since this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first service of the first terminal device to occupy the spectrum resources of the first network based on service demand, the scheme design is more flexible.

[0166] Optionally, the third message in this embodiment of the application may also include the duration for which the first terminal device's first service occupies the spectrum resources of the first network. Thus, when the duration for which the first terminal device's first service occupies the spectrum resources of the first network reaches this duration, the access network device may cease occupying the spectrum resources of the first network for the first terminal device's first service, thereby achieving effective control over the spectrum resource occupancy of different networks.

[0167] Based on the spectrum resource sharing method provided in this application embodiment, since the access network device can only occupy the spectrum resources of the first network for the first terminal device's first service according to the second instruction information sent by the mobility management entity after the mobility management entity determines that the first terminal device's first service is allowed to occupy the spectrum resources of the first network, on the one hand, it can avoid the spectrum resource congestion problem caused by occupying spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services); on the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the operator's commercial interests.

[0168] The actions of the movement management entity in steps S701 to S703 above can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the mobility management entity to execute the above steps S701 to S703. The actions of the access network device can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the access network device to execute, and this embodiment does not impose any restrictions on this.

[0169] It should be noted that, Figure 7 The illustrated embodiment uses the example of a mobility management entity (MMI) sending second indication information to an access network device after determining that a first service of a first terminal device is permitted to occupy spectrum resources of the first network. Alternatively, in this embodiment, the MMI may obtain the second indication information and send it to the access network device; this embodiment does not specifically limit this. Obtaining the second indication information includes: the MMI obtaining the second indication information from the first terminal device's subscription information, the first terminal device's access and mobility control policy information, or the second network's local policy information. Other related descriptions can be found in [reference needed]. Figure 7 The embodiments shown will not be described in detail here.

[0170] like Figure 8 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0171] S801, The session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0172] Among them, the first terminal device is subscribed to the second network, and the session management entity is the session management entity within the second network.

[0173] In one possible implementation, step S801 includes: the session management entity determining, based on the subscription information and / or session policy information of the first terminal device, that the first session of the first terminal device is allowed to occupy spectrum resources of the first network; or, the session management entity determining, based on the subscription information and / or session policy information of the first terminal device, that the first QoS flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network.

[0174] In one possible implementation, the session policy information of the first terminal device is obtained by the session management entity from the policy control entity. For example, the session management entity receives a fifth message from the policy control entity, which includes the session policy information of the first terminal device. Of course, the session policy information of the first terminal device can also be pre-configured on the session management entity, and this embodiment of the application does not specifically limit this.

[0175] Optionally, the session policy information of the first terminal device includes fourth indication information, which indicates that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the fourth indication information indicates that the session or QoS flow established according to the session policy information of the first terminal device is allowed to occupy the spectrum resources of the first network; or, the fourth indication information indicates that the session corresponding to a specific NSSAI is allowed to occupy the spectrum resources of the first network; or, the fourth indication information indicates that the session corresponding to a specific NSSAI and DNN is allowed to occupy the spectrum resources of the first network.

[0176] Optionally, the service corresponding to the first QoS stream of the first session of the first terminal device is the first service. This can be understood as the service to which the first QoS stream of the first session of the first terminal device belongs being the first service. This will not be elaborated further below.

[0177] Optionally, when the service corresponding to the first QoS flow of the first session of the first terminal device is the first service, the relevant description of the subscription information of the first terminal device can be found in [reference needed]. Figure 7 The embodiments shown will not be described in detail here.

[0178] Optionally, when the service corresponding to the first QoS flow of the first session of the first terminal device is the first service, the session policy information of the first terminal device includes: seventh information, which is used to characterize the first service of the first terminal device to occupy the spectrum resources of the first network.

[0179] For example, when the subscription information of the first terminal device includes the fourth information, and the service corresponding to the first QoS flow of the first session of the first terminal device is the first service, the session management entity can determine, based on the subscription information of the first terminal device, that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network. Alternatively, when the session policy information of the first terminal device includes the fourth indication information, which indicates that the session corresponding to a specific NSSAI and DNN is allowed to occupy the spectrum resources of the first network, and the first session of the first terminal device is the session corresponding to that specific NSSAI and DNN, the session management entity can determine, based on the session policy information of the first terminal device, that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network. Alternatively, when the subscription information of the first terminal device includes first information, and the session policy information of the first terminal device includes fourth indication information, the fourth indication information indicating information that allows a session corresponding to a specific NSSAI and DNN to occupy spectrum resources of the first network, and the first session of the first terminal device is a session corresponding to that specific NSSAI and DNN, the session management entity can determine, based on the subscription information and the session policy information of the first terminal device, that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network. Alternatively, when the subscription information of the first terminal device includes the identifier information of the first service of the first terminal device, the service corresponding to the first QoS flow of the first session of the first terminal device is the first service, and the session policy information of the first terminal device includes seventh information, the seventh information being used to characterize that the first service of the first terminal device is allowed to occupy spectrum resources of the first network, the session management entity can determine, based on the subscription information and the session policy information of the first terminal device, that the first QoS flow of the first session of the first terminal device is allowed to occupy spectrum resources of the first network.

[0180] For example, when the subscription information of the first terminal device includes the fourth information, the service corresponding to the first QoS flow of the first session of the first terminal device is the first service, and the session policy information of the first terminal device includes the fourth indication information, the fourth indication information indicates that the session corresponding to a specific NSSAI and DNN is allowed to occupy the spectrum resources of the first network, but the first session of the first terminal device is not the session corresponding to the specific NSSAI and DNN, the session management entity can determine, based on the subscription information and the session policy information of the first terminal device, that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is not allowed to occupy the spectrum resources of the first network.

[0181] S802. The session management entity sends a third indication message to the access network device. Correspondingly, the access network device receives the third indication message from the session management entity.

[0182] The third indication information indicates that the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, or the third indication information indicates that the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network. This access network device is a shared access network device between the first network and the second network.

[0183] In one possible implementation, the third instruction information in this embodiment is the same as the fourth instruction information in the session policy information of the first terminal device.

[0184] S803. The access network device occupies the spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device, according to the third instruction information.

[0185] It should be noted that the access network device occupying the spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device can be understood as the access network device being able to transmit the data of the first session of the first terminal device or the first QoS flow of the first session of the first terminal device through the spectrum resources of the first network. This is explained here and will not be repeated below.

[0186] For example, assuming the spectrum resources of the first network are 100MHz between 3.5-3.6GHz, and the available spectrum resources of the second network subscribed to by the first terminal device are only 20MHz, which cannot meet the requirements of the first session of the first terminal device or the first QoS flow of the first session of the first terminal device (e.g., requiring 40MHz of spectrum resources), the access network device may occupy the spectrum resources of the first network to meet the requirements of the first session of the first terminal device or the first QoS flow of the first session of the first terminal device.

[0187] In one possible implementation, after the access network device has occupied the remaining available spectrum resources of the second network (e.g., 20MHz of available spectrum resources between 3.4-3.5G) for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device, the access network device may continue to occupy the spectrum resources of the first network (e.g., 20MHz of available spectrum resources between 3.5-3.6G) for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device.

[0188] Alternatively, in another possible implementation, although the spectrum resources of the first network are 100MHz between 3.4G and 3.5G, and the spectrum resources of the second network are also 100MHz between 3.4G and 3.5G, under network sharing conditions, the first network and the second network can dynamically occupy any 100MHz of spectrum resources between 3.4G and 3.6G. In this case, the access network device can occupy a portion of the remaining available spectrum resources of the second network and a portion of the spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device. For example, the access network device can occupy 10MHz of spectrum resources of the second network (e.g., 10MHz of the 20MHz available spectrum resources between 3.4G and 3.5G) and 30MHz of spectrum resources of the first network (e.g., 30MHz of the 100MHz spectrum resources between 3.5G and 3.6G) for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device.

[0189] It should be noted that the access network device may allocate the spectrum resources of the first network occupied by the first session of the first terminal device to the first session of the first terminal device and / or other sessions of the first terminal device and / or other terminal devices of the second network. If the access network device allocates the spectrum resources of the first network occupied by the first session of the first terminal device to other sessions of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate a corresponding amount of spectrum resources of the second network allocated to the other sessions of the first terminal device and / or other terminal devices of the second network to the first session of the first terminal device. This application embodiment does not limit how the access network device allocates the spectrum resources of the first network and the spectrum resources of the second network occupied by the first session of the first terminal device. For example, continuing the above example, if the spectrum resources of the first network occupied to meet the needs of the first session of the first terminal device (e.g., 20MHz of spectrum resources out of 100MHz spectrum resources between 3.5-3.6G) are allocated to other sessions of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate the 20MHz spectrum resources of the second network allocated to other sessions of the first terminal device and / or other terminal devices of the second network to the first session of the first terminal device, that is, allocate the 40MHz spectrum resources between 3.4-3.5G to the first session of the first terminal device. Alternatively, following the example above, if a portion of the spectrum resources (e.g., 10MHz of spectrum resources) of the first network occupied to meet the needs of the first session of the first terminal device (e.g., 30MHz of spectrum resources out of 100MHz spectrum resources between 3.5-3.6G) are allocated to the first session of the first terminal device, and a portion of the spectrum resources (e.g., 20MHz of spectrum resources) are allocated to other sessions of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate the 20MHz spectrum resources of the second network allocated to other sessions of the first terminal device and / or other terminal devices of the second network to the first session of the first terminal device, that is, allocate the 30MHz spectrum resources between 3.4-3.5G to the first session of the first terminal device.

[0190] It should be noted that the access network device may allocate the spectrum resources of the first network occupied by the first QoS flow of the first session of the first terminal device to the first QoS flow of the first session of the first terminal device and / or other QoS flows of the first session of the first terminal device and / or other sessions of the first terminal device and / or other terminal devices of the second network. If the access network device allocates the spectrum resources of the first network occupied by the first QoS flow of the first session of the first terminal device to other QoS flows of the first session of the first terminal device and / or other sessions of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate a corresponding number of spectrum resources of the second network allocated to the other QoS flows of the first session of the first terminal device and / or other sessions of the first terminal device and / or other terminal devices of the second network to the first QoS flow of the first session of the first terminal device. This application embodiment does not limit how the access network device allocates the spectrum resources of the first network and the second network occupied by the first QoS flow of the first session of the first terminal device. For example, continuing the above example, if the spectrum resources of the first network occupied to meet the requirements of the first QoS flow of the first session of the first terminal device (e.g., 20MHz of spectrum resources out of 100MHz spectrum resources between 3.5-3.6G) are allocated to other QoS flows of the first session of the first terminal device and / or other sessions of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate the other QoS flows of the first session of the first terminal device and / or the 20MHz spectrum resources of the second network allocated to other QoS flows of the first session of the first terminal device and / or other sessions of the first terminal device and / or other terminal devices of the second network to the first QoS flow of the first session of the first terminal device, that is, the 40MHz spectrum resources between 3.4-3.5G are allocated to the first QoS flow of the first session of the first terminal device. Alternatively, following the example above, if a portion of the spectrum resources (e.g., 10MHz of spectrum resources) of the first network (e.g., 30MHz of spectrum resources out of 100MHz spectrum resources between 3.5-3.6G) used to meet the requirements of the first QoS flow of the first session of the first terminal device is allocated to the first QoS flow of the first terminal device, and a portion of the spectrum resources (e.g., 20MHz of spectrum resources) is allocated to other QoS flows of the first session of the first terminal device and / or other sessions of the first terminal device and / or other terminal devices of the second network, then the access network device may allocate the 20MHz spectrum resources of the second network allocated to the other QoS flows of the first session of the first terminal device and / or other sessions of the first terminal device and / or other terminal devices of the second network to the first QoS flow of the first session of the first terminal device, that is, the 30MHz spectrum resources between 3.4-3.5G are allocated to the first QoS flow of the first session of the first terminal device.

[0191] Based on the spectrum resource sharing method provided in this application embodiment, since the session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can occupy the spectrum resources of the first network according to the third indication information sent by the session management entity. Therefore, on the one hand, it can avoid the problem of spectrum resource congestion caused by occupying the spectrum resources of different networks for all terminal devices or all services of terminal devices, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services); on the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy the spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the commercial interests of the operator.

[0192] The actions of the session management entity in steps S801 to S803 above can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the session management entity to execute the above steps S801 to S803. The actions of the access network device can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the access network device to execute, and this embodiment does not impose any restrictions on this.

[0193] It should be noted that, Figure 8 The illustrated embodiment uses the example of a session management entity sending third indication information to an access network device after determining that a first session of a first terminal device or a first QoS flow of a first session of a first terminal device is allowed to occupy spectrum resources of the first network. Alternatively, in this embodiment, the session management entity may obtain the third indication information and send it to the access network device; this embodiment does not specifically limit this. Obtaining the third indication information includes the session management entity obtaining it from the subscription information or session policy information of the first terminal device. Other related descriptions can be found in [reference needed]. Figure 8 The embodiments shown will not be described in detail here.

[0194] like Figure 9 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0195] S901, The mobile management entity obtains the contract information of the first terminal device.

[0196] The subscription information of the first terminal device includes information on the first spectrum resource, which is the spectrum resource of the first network that the first terminal device is allowed to occupy. The first terminal device is subscribed to the second network, and the mobility management entity is the mobility management entity within the second network.

[0197] Optionally, the information of the first spectrum resource is the identifier of the first spectrum resource.

[0198] It should be noted that the subscription information of the first terminal device may include the identifiers of one or more first spectrum resources, and this application embodiment does not specifically limit this.

[0199] S902, the Mobility Management Entity sends information about the first spectrum resource to the access network device. Correspondingly, the access network device receives the information about the first spectrum resource from the Mobility Management Entity; the access network device is a shared access network device between the first network and the second network.

[0200] S903, the access network equipment occupies the first spectrum resource as the first terminal equipment.

[0201] After obtaining information about the first spectrum resource, the access network device can determine the first spectrum resource based on this information. Furthermore, the access network device allocates the determined first spectrum resource for the first terminal device.

[0202] It should be noted that the access network device occupying the first spectrum resource for the first terminal device can be understood as the access network device occupying the first spectrum resource for all services of the first terminal device, or it can be understood as the access network device being able to transmit all service data of the first terminal device through the first spectrum resource. This is explained uniformly here and will not be repeated below.

[0203] For example, assuming the spectrum resources of the first network are 100MHz between 3.5-3.6GHz, and the spectrum resources of the second network to which the first terminal device is subscribed are 100MHz between 3.4-3.5GHz, then:

[0204] When the access network device determines that the spectrum resources of the second network subscribed by the first terminal device (e.g., 20MHz of available spectrum resources between 3.4-3.5G) cannot meet the service needs of the first terminal device, assuming that the first spectrum resource indicated by the first spectrum resource information is 50MHz between 3.50-3.55G, the access network device can continue to occupy the spectrum resources of the first network (e.g., 20MHz of spectrum resources within the 50MHz spectrum resources between 3.50-3.55G) for the first terminal device after occupying the spectrum resources of the second network (e.g., 20MHz of available spectrum resources between 3.4-3.5G) for the first terminal device.

[0205] Alternatively, when the access network device determines that the spectrum resources of the second network subscribed by the first terminal device (e.g., 20MHz of available spectrum resources between 3.4-3.5G) cannot meet the service needs of the first terminal device, assuming that the first spectrum resource information indicates that the first spectrum resource is 50MHz between 3.50-3.55G, the access network device will occupy the spectrum resources of the second network (e.g., 10MHz of spectrum resources from the 20MHz of available spectrum resources between 3.4-3.5G) and the spectrum resources of the first network (e.g., 30MHz of spectrum resources from the 50MHz of spectrum resources between 3.50-3.55G) for the first terminal device.

[0206] It should be noted that the above example illustrates the specific frequency band to which the first spectrum resource is indicated by the information on the first spectrum resource. Of course, the information on the first spectrum resource may not specify a particular frequency band, but only indicate how much can be occupied. For example, in the above example, the information on the first spectrum resource may indicate that the first spectrum resource is 50MHz; this embodiment of the application does not impose a specific limitation on this.

[0207] Based on the spectrum resource sharing method provided in this application embodiment, since the access network device can only occupy the first spectrum resource for the first terminal device according to the first spectrum resource information sent by the mobility management entity after the mobility management entity determines that the first terminal device is allowed to occupy the spectrum resource of the first network, it can avoid the spectrum resource congestion problem caused by all terminal devices or all services of terminal devices occupying the spectrum resource of the other network, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services). On the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy the spectrum resource of the other network, the operator of the local network may pay higher fees to the operator of the other network than to the operator of the local network, thereby maximizing the commercial interests of the operator.

[0208] The actions of the movement management entity in steps S901 to S903 above can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the mobility management entity to execute the above steps S901 to S903. The actions of the access network device can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the access network device to execute, and this embodiment does not impose any restrictions on this.

[0209] like Figure 10 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0210] S1001, The mobile management entity obtains the contract information of the first terminal device.

[0211] The subscription information of the first terminal device includes information on the second spectrum resources. The second spectrum resources are the spectrum resources of the first network that the first terminal device is allowed to occupy for its first service. The first terminal device is subscribed to the second network, and the mobility management entity is the mobility management entity within the second network.

[0212] In this embodiment of the application, the first service of the first terminal device may include, for example, vehicle networking service, terminal device positioning service, IP IMS service, or high-value services such as Migu Video.

[0213] In one possible implementation, the information of the second spectrum resource includes a first identifier. This first identifier is mapped to both the identifier of the second spectrum resource and the identifier of the first service. In other words, the first identifier can indicate both the identifier of the second spectrum resource and the first service.

[0214] It should be noted that there is a mapping relationship between the first identifier and the identifier of the second spectrum resource and the identifier information of the first service. This can be understood as a mapping relationship between the first identifier and the identifier of the second spectrum resource, and a mapping relationship between the first identifier and the identifier information of the first service. Alternatively, there is a mapping relationship between the first identifier and the identifier of the second spectrum resource and the identifier information of the first service. This can be understood as a mapping relationship between the first identifier, the identifier of the second spectrum resource, and the identifier information of the first service. This embodiment of the application does not specifically limit this.

[0215] It should be noted that the first identifier may indicate one or more second spectrum resources and one or more first services corresponding to each second spectrum resource, but this application embodiment does not specifically limit this.

[0216] In another possible implementation, the information of the second spectrum resource in this embodiment includes an identifier of the second spectrum resource and an identifier of the first service. In other words, this embodiment can determine the second spectrum resource based on its identifier and determine the first service based on its identifier. A description of the identifier of the first service can be found here. Figure 7 The embodiments shown will not be described in detail here.

[0217] It should be noted that the information of the second spectrum resource in this application embodiment may include multiple identifiers of the second spectrum resource, and each identifier of the second spectrum resource may correspond to the identifier information of one or more first services. That is to say, in this application embodiment, the identifier of the second spectrum resource and the identifier information of the first service may have a one-to-many relationship or a one-to-one relationship, and this application embodiment does not specifically limit this.

[0218] For example, information about the second spectrum resource may be shown in Table 1, Table 2, or Table 3.

[0219] Table 1

[0220] Identification of the first spectrum resource Identification information for the first business A Identification information for service A and identification information for service B

[0226] S1002, the Mobility Management Entity sends information about the second spectrum resource to the access network device. Correspondingly, the access network device receives the second spectrum resource information from the Mobility Management Entity. This access network device is a shared access network device between the first network and the second network.

[0227] S1003. The access network equipment occupies the second spectrum resource for the first service of the first terminal equipment according to the information of the second spectrum resource.

[0228] Wherein, when the information of the second spectrum resource includes the first identifier, step S1003 includes: the access network device determining the second spectrum resource according to the first identifier and the mapping relationship between the first identifier and the identifier of the second spectrum resource; the access network device determining the first service according to the first identifier and the mapping relationship between the first identifier and the identifier information of the first service; and then, the access network device occupies the second spectrum resource for the first service of the first terminal device.

[0229] Wherein, when the information of the second spectrum resource includes the identifier of the second spectrum resource and the identifier information of the first service, step S1003 includes: the access network device determining the second spectrum resource according to the identifier of the second spectrum resource; the access network device determining the first service according to the identifier information of the first service; and then, the access network device occupies the second spectrum resource for the first service of the first terminal device.

[0230] It should be noted that, in the embodiments of this application, the first service of the access network device occupying the second spectrum resource of the first terminal device can be understood as the access network device being able to transmit the data of the first service of the first terminal device through the second spectrum resource. This will be explained uniformly here and will not be repeated below.

[0231] For example, assuming the spectrum resources of the first network are 100MHz between 3.5-3.6GHz, and the spectrum resources of the second network to which the first terminal device is subscribed are 100MHz between 3.4-3.5GHz, then:

[0232] Assuming the second spectrum resource information indicates a 50MHz spectrum resource between 3.50-3.55GHz, and the first service indicated by the second spectrum resource information is a vehicle-to-everything (V2X) service, when the access network device determines that the spectrum resources of the second network subscribed to by the first terminal device (e.g., 20MHz of available spectrum resources between 3.4-3.5GHz) cannot meet the needs of the first terminal device's first service, the access network device can, after occupying the spectrum resources of the second network (e.g., 20MHz of available spectrum resources between 3.4-3.5GHz) for the first terminal device's first service, continue to occupy the spectrum resources of the first network (e.g., 20MHz of spectrum resources out of the 50MHz spectrum resources between 3.50-3.55GHz) for the first terminal device's first service.

[0233] Alternatively, assuming the second spectrum resource information indicates that the second spectrum resource is 50MHz between 3.50-3.55G, and the first service indicated by the second spectrum resource information is vehicle-to-everything (V2X) service, when the access network device determines that the spectrum resources of the second network subscribed to by the first terminal device (e.g., 20MHz of available spectrum resources between 3.4-3.5G) cannot meet the needs of the first terminal device's first service, the access network device can occupy the spectrum resources of the second network (e.g., 10MHz of spectrum resources from the 20MHz of available spectrum resources between 3.4-3.5G) and the spectrum resources of the first network (e.g., 30MHz of spectrum resources from the 50MHz of spectrum resources between 3.50-3.55G) for the first terminal device's first service.

[0234] It should be noted that the above example illustrates the specific frequency band to which the second spectrum resource is indicated by the information on the second spectrum resource. Of course, the spectrum resource of the first network indicated by the information on the second spectrum resource may not specify a particular frequency band, but only indicate how much can be occupied. For example, in the above example, the information on the second spectrum resource may indicate that the second spectrum resource is 50MHz; this embodiment of the application does not impose a specific limitation on this.

[0235] Based on the spectrum resource sharing method provided in this application embodiment, since the access network device can only occupy the second spectrum resource for the first terminal device's first service according to the second spectrum resource information sent by the mobile management entity after the mobile management entity determines that the first terminal device's first service is allowed to occupy the spectrum resource of the first network, on the one hand, it can avoid the spectrum resource congestion problem caused by all terminal devices or all services of terminal devices occupying spectrum resources of different networks, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services); on the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of different networks, the operator of this network may pay higher fees to the operators of different networks than to the operators of this network, thereby maximizing the operator's commercial interests.

[0236] The actions of the movement management entity in steps S1001 to S1003 can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the mobility management entity to execute the above steps S1001 to S1003. The actions of the access network device can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the access network device to execute, and this embodiment does not impose any restrictions on this.

[0237] like Figure 11 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0238] S1101, the access network device determines that the spectrum resource demand of the second network subscribed by the first terminal device is greater than or equal to a preset threshold. This access network device is a shared access network device between the first network and the second network.

[0239] S1102, The access network device sends a sixth message to the session management entity. Correspondingly, the session management entity receives the sixth message from the access network device.

[0240] The sixth message is used to indicate that the spectrum resources of the second network subscribed to by the first terminal device are insufficient; or, the sixth message is used to request confirmation on whether the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network. The session management entity is the session management entity within the second network.

[0241] For example, in this embodiment of the application, when the sixth message includes the identifier of the first session of the first terminal device, the sixth message can be used to request confirmation as to whether the first session of the first terminal device is allowed to occupy the spectrum resources of the first network; or, when the sixth message includes the identifier of the first QoS stream of the first session of the first terminal device, the sixth message can be used to request confirmation as to whether the first QoS stream of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network; or, when the sixth message includes the identifier of the first session of the first terminal device and the identifier of the first QoS stream of the first session of the first terminal device, the sixth message is used to indicate that the spectrum resources of the second network subscribed to by the first terminal device are insufficient. This embodiment of the application does not specifically limit this.

[0242] S1103. In response to the sixth message, the session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0243] S1104. The session management entity sends a third indication message to the access network device. Accordingly, the access network device receives the third indication message from the session management entity, which indicates that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0244] S1105. The access network device occupies the spectrum resources of the first network for the first session of the first terminal device or the first QoS flow of the first session of the first terminal device, according to the third instruction information.

[0245] The relevant descriptions of steps S1103-S1105 above can be found in the following references. Figure 8 Steps S801-S803 of the embodiment described herein will not be repeated here.

[0246] Optionally, the spectrum resource sharing method provided in this application embodiment further includes: a session management entity sending a duration to the access network device allowing the first session of the first terminal device or the first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network. Thus, when the duration for which the first session of the first terminal device or the first QoS flow of the first session of the first terminal device occupies the spectrum resources of the first network reaches the specified duration, the access network device can cease allowing the first session of the first terminal device or the first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network, thereby achieving effective control over the spectrum resource occupation of different networks.

[0247] Based on the spectrum resource sharing method provided in this application embodiment, since the session management entity determines that the first session of the first terminal device or the first QoS flow of the first session of the first terminal device is allowed to occupy the spectrum resources of the first network, the access network device can then occupy the spectrum resources of the first network according to the third indication information sent by the session management entity. Therefore, on the one hand, it can avoid the spectrum resource congestion problem caused by all terminal devices or all services of a terminal device occupying spectrum resources of a different network, thereby improving the experience of specific users (such as high-value users) or specific services (such as high-value services); on the other hand, it can avoid the problem that when non-specific users (such as low-value users) or non-specific services (such as low-value services) occupy spectrum resources of a different network, the operator of this network may pay higher fees to the operator of the different network than to the operator of this network, thereby maximizing the operator's commercial interests. Furthermore, since this scheme involves the access network device dynamically requesting the mobility management entity whether to allow the first session of the first terminal device or the first QoS flow of the first session of the first terminal device to occupy the spectrum resources of the first network according to service needs, the scheme design is more flexible.

[0248] The actions of the session management entity in steps S1101 to S1105 above can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the session management entity to execute the above steps S1101 to S1105, and the actions of the access network device can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the access network device to execute, and this embodiment does not impose any restrictions on this.

[0249] The following will be based on Figure 2 or Figure 3 The communication system described is applied to, for example Figure 4 The 5G network shown, taking the first terminal device subscribed to the second network as an example, is used for... Figures 6 to 11 The method for sharing spectrum resources is illustrated by example.

[0250] It should be noted that the message names between network elements or the names of parameters in the messages in the following embodiments of this application are just examples. Other names may be used in the specific implementation. This application does not limit them in this respect.

[0251] Combination Figure 6 or Figure 7 The method for sharing spectrum resources, in order to Figure 2 The communication system described is applied to, for example Figure 4Taking the 5G network shown as an example, such as Figure 12 As shown in the figure, a method for spectrum resource sharing provided in an embodiment of this application is described below.

[0252] S1201, The first terminal device sends a registration request to the AMF. Correspondingly, the AMF receives the registration request from the first terminal device.

[0253] S1202, AMF sends a request to UDM to obtain subscription information (Nudm_SDM_Get request) from the subscription data management service (SDM) provided by UDM. Correspondingly, UDM receives the request from AMF. This request is used to request subscription information from the first terminal device.

[0254] It should be noted that step S1202 is executed when the first terminal device is initially registered to the network, or when it is not initially registered to the network but there is no user subscription information on the AMF.

[0255] S1203, UDM obtains the subscription information of the first terminal device. The subscription information includes first information, or the subscription information includes at least one of the following: first information, fourth information, or identification information of the first service of the first terminal device.

[0256] The relevant description of the first information can be found in the following reference. Figure 6 The description of the fourth information or the identification information of the first service of the first terminal device shown in the embodiment can be found by referring to... Figure 7 The embodiments shown will not be described in detail here.

[0257] In this embodiment of the application, the subscription information of the first terminal device may also include some existing subscription information, such as the slice information and / or mobility restriction information of the first terminal device, etc. This embodiment of the application does not specifically limit this.

[0258] In one possible implementation, the subscription information of the first terminal device is pre-configured in the UDR. Furthermore, when the UDM receives a request from the AMF to obtain subscription information, the UDM retrieves the subscription information of the first terminal device from the UDR and stores it in the UDM.

[0259] S1204, UDM sends a Nudm_SDM_Get response to the AMF, which provides a subscription information management service. Correspondingly, the AMF receives the Nudm_SDM_Get response from UDM. This response includes the subscription information of the first terminal device.

[0260] S1205, AMF sends an N2 message to RAN device based on the subscription information of the first terminal device. Correspondingly, RAN device receives the N2 message from AMF.

[0261] It should be noted that the N2 message in this application embodiment is only... Figure 6 The first message or in the illustrated embodiment Figure 7 This is a specific example of the third message in the illustrated embodiment. Of course, Figure 6 The first message or in the illustrated embodiment Figure 7 The third message in the illustrated embodiment can also be other messages, and this application embodiment does not specifically limit this.

[0262] In one possible implementation, when the subscription information of the first terminal device includes the aforementioned first information, the AMF can determine the permitted spectrum resources of the first network for the first terminal device to occupy based on at least one of the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network. A related description can be found in [reference needed]. Figure 6 The aforementioned embodiments will not be repeated here. Furthermore, the N2 message includes first indication information, which indicates that the first terminal device is permitted to occupy spectrum resources of the first network.

[0263] In another possible implementation, when the subscription information of the first terminal device includes at least one of the first information, the fourth information, or the identification information of the first service of the first terminal device, the AMF can determine the spectrum resources of the first network that the first service of the first terminal device is allowed to occupy based on at least one of the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network. A related description can be found in [reference needed]. Figure 7 The aforementioned embodiments will not be repeated here. Further, the N2 message includes second indication information, which indicates that the first service of the first terminal device is permitted to occupy the spectrum resources of the first network. For example, the second indication information may include indication information allowing the first service of the first terminal device to occupy the spectrum resources of the first network, and identification information of the first service of the first terminal device permitted to occupy the spectrum resources of the first network.

[0264] Optionally, when the AMF determines that the first terminal device is not allowed to occupy the spectrum resources of the first network, the aforementioned N2 message includes a seventh indication, which indicates that the first terminal device is not allowed to occupy the spectrum resources of the first network. Of course, the RAN device can also implicitly learn that the network does not allow the first terminal device to occupy the spectrum resources of the first network. For example, when the N2 message does not include the first or second indication, the RAN device can determine that the network does not allow the first terminal device to occupy the spectrum resources of the first network; this embodiment does not specifically limit this.

[0265] S1206, AMF sends a registration accept message to the first terminal device. Correspondingly, the first terminal device receives the registration accept message from AMF.

[0266] Furthermore, in this embodiment of the application, if the N2 message includes first indication information or second indication information, the spectrum resource sharing method provided in this embodiment of the application further includes the following step S1207:

[0267] S1207, RAN equipment occupies spectrum resources of the first network for the first terminal equipment or the first service of the first terminal equipment.

[0268] In this embodiment of the application, when the N2 message includes first indication information, the RAN device can allocate spectrum resources of the first network for the first terminal device according to the first indication information. Related descriptions and examples can be found in the following references. Figure 6 The embodiments shown will not be described in detail here.

[0269] In this embodiment of the application, when the N2 message includes second indication information, the RAN device can allocate spectrum resources of the first network for the first service of the first terminal device according to the second indication information. Related descriptions and examples can be found in the following references. Figure 7 The embodiments shown will not be described in detail here.

[0270] It should be noted that, in this embodiment, the RAN device may allocate spectrum resources of the first network for the first terminal device or its first service when it determines that the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to a preset threshold. Alternatively, after receiving the N2 message, the RAN device may directly allocate spectrum resources of the first network for the first terminal device or its first service without determining whether the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to the preset threshold. This embodiment does not specifically limit this approach.

[0271] Figure 12The illustrated embodiment uses the registration process as an example. Optionally, the above-described spectrum resource sharing method can also be applied to the service request process. For example, when the above-described spectrum resource sharing method is applied to the service request process: on the one hand, step S1201 is replaced by the first terminal device being in an idle state and sending a service request message to the AMF. On the other hand, step S1206 is replaced by the AMF sending a service accept message to the first terminal device. Other related descriptions can be found in [reference needed]. Figure 12 The embodiments shown are not described in detail here.

[0272] Figure 12 The technical effects of the embodiments shown can be referred to Figure 6 or Figure 7 The embodiments shown will not be described in detail here.

[0273] Among them, the actions of AMF in steps S1201 to S1207 above can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to execute the instruction AMF. The actions of the RAN device in steps S1201 to S1207 can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the RAN device to execute, and this embodiment does not impose any restrictions on this.

[0274] Combination Figure 8 The method for sharing spectrum resources, in order to Figure 3 The communication system described is applied to, for example Figure 4 Taking the 5G network shown as an example, such as Figure 13 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0275] S1301, The first terminal device is currently in a connected state.

[0276] In this embodiment of the application, the first terminal device being in a connected state means that the first terminal device has a signaling connection with the network, such as a non-access stratum (NAS) signaling connection between the first terminal device and the AMF.

[0277] S1302, the first terminal device sends a PDU session establishment request to the AMF. Correspondingly, the AMF receives the PDU session establishment request from the first terminal device. This PDU session establishment request is used to request the establishment of a first PDU session for the first terminal device; relevant descriptions can be found in existing technologies and will not be repeated here.

[0278] It should be noted that this application embodiment uses a 5G network as an example for illustration, therefore the first session is the first PDU session. Of course, in other networks in the future, the session can be any session other than a PDU session, and this application embodiment does not specifically limit this.

[0279] S1303, AMF sends a PDU session establishment request to SMF via the PDU session creation session management (SM) context request (Nsmf_PDUSession_CreateSM context request) provided by SMF. Correspondingly, SMF receives the CreateSM context request from AMF.

[0280] It should be noted that the SM context creation request in this embodiment is only a... Figure 8 A specific example of the fifth message in the illustrated embodiment, wherein the fifth message is used to request the establishment of a first PDU session for the first terminal device. Of course, Figure 8 The fifth message in the illustrated embodiment can also be other messages, and this application embodiment does not specifically limit this.

[0281] S1304. Based on the subscription information and / or session policy information of the first terminal device, the SMF determines whether to allow the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device to occupy the first network spectrum resources.

[0282] In this embodiment, if the SMF does not have the subscription information of the first terminal device, the SMF can request the subscription information of the first terminal device from the UDM. Furthermore, if the UDM does not have the subscription information of the first terminal device, the UDM can request the subscription information of the first terminal device from the UDR. This is explained uniformly here and will not be repeated below.

[0283] In this embodiment, the relevant descriptions of the subscription information and / or session policy information of the first terminal device can be found in [reference]. Figure 8 The embodiments shown will not be described in detail here.

[0284] It should be noted that, in this embodiment of the application, when the SMF obtains the session policy information of the first terminal device from the PCF, Figure 8 The fourth indication information in the illustrated embodiment may be included in the policy and charging control (PCC) rules in the session policy information of the first terminal device, or the session policy information of the first terminal device may include PCC rules and Figure 8The fourth instruction information shown in the illustrated embodiment is not specifically limited in this application embodiment. It is understood that... Figure 8 In the embodiment shown, the fourth indication information indicates that the session or QoS flow established according to the session policy information is allowed to occupy the spectrum resources of the first network. This can also be understood as allowing the session or QoS flow established according to the PCC rule to occupy the spectrum resources of the first network. This is explained uniformly here and will not be repeated below.

[0285] S1305. The SMF sends a PDU session establishment accept message to the AMF via the PDU session creation context response (Nsmf_PDUSession_CreateSM context response) provided by the SMF. Correspondingly, the AMF receives the creation SM context response from the SMF.

[0286] S1306, AMF sends an N2 message to the RAN device. Correspondingly, the RAN device receives the N2 message from the AMF.

[0287] Regarding steps S1305 and S1306 above:

[0288] When the SMF determines that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network, the SM context creation response in step S1305 includes third indication information, and subsequently the N2 message in step S1306 includes the third indication information. The third indication information indicates that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0289] Optionally, in this embodiment, when the SMF determines that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is not allowed to occupy the spectrum resources of the first network, the creation SM context response in step S1305 may include an eighth indication information, and then the N2 message in step S1306 includes the eighth indication information, which indicates that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is not allowed to occupy the spectrum resources of the first network. Of course, the RAN device may also implicitly learn that the network does not allow the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network. For example, when the N2 message does not include the third indication information, the RAN device may determine that the network does not allow the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network. This embodiment does not specifically limit this.

[0290] S1307, AMF sends a PDU session establishment accept message to the first terminal device. Correspondingly, the first terminal device receives the PDU session establishment accept message from AMF.

[0291] It should be noted that in this embodiment, steps S1307 and S1306 can be performed simultaneously; or, the PDU session establishment acceptance message in step S1307 is included in the N2 message in step S1306 and sent to the RAN device, and the RAN device further sends the PDU session establishment acceptance message to the first terminal device. This embodiment does not specifically limit this.

[0292] Furthermore, in this embodiment of the application, if the N2 message includes third indication information, the spectrum resource sharing method provided in this embodiment of the application further includes the following step S1308:

[0293] S1308, the RAN device occupies the spectrum resources of the first network for the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device.

[0294] For details and examples regarding the RAN device occupying spectrum resources of the first network for the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device, please refer to [reference needed]. Figure 8 The embodiments shown will not be described in detail here.

[0295] It should be noted that, in this embodiment, the RAN device may, when determining that the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to a preset threshold, allocate spectrum resources of the first network for the first PDU session or the first QoS flow of the first PDU session of the first terminal device according to the third indication information. Alternatively, after receiving the N2 message, the RAN device may directly allocate spectrum resources of the first network for the first PDU session or the first QoS flow of the first PDU session of the first terminal device without determining whether the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to the preset threshold. This embodiment does not specifically limit this approach.

[0296] Figure 13 The illustrated embodiment uses the PDU session establishment process as an example for explanation. Optionally, the above-described spectrum resource sharing method can also be applied to the PDU session activation process. For example, when the above-described spectrum resource sharing method is applied to the PDU session activation process: on the one hand, step S1301 is optional, that is, the first terminal device can be in a connected state or an idle state. On the other hand, the PDU session establishment request in step S1302 can be replaced with a service request for requesting PDU session activation, the PDU session establishment request in step S1303 can be replaced with an update SM context request (Nsmf_PDUSession_UpdateSM context request) provided by the SMF, the create SM context response in step S1305 can be replaced with an update session management context response (Nsmf_PDUSession_UpdateSM context response) provided by the SMF, and the PDU session establishment acceptance message in the create SM context response in step S1305 and the PDU session establishment acceptance message in step S1307 can be replaced with a service acceptance message. Other related descriptions can be found in [reference needed]. Figure 13 The embodiments shown are not described in detail here.

[0297] Figure 13 The technical effects of the embodiments shown can be referred to Figure 8 The embodiments shown will not be described in detail here.

[0298] Among them, the SMF action in steps S1301 to S1308 above can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to execute the instruction SMF. The actions of the RAN device in steps S1301 to S1308 can be performed by... Figure 5The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the RAN device to execute, and this embodiment does not impose any restrictions on this.

[0299] It should be noted that, Figure 13 The illustrated embodiment uses the example of establishing the first QoS stream of the first PDU session of the first terminal device simultaneously during the establishment process of the first PDU session of the first terminal device. Of course, the first QoS stream of the first PDU session of the first terminal device may not be established in the same process as the first PDU session of the first terminal device. For example, as... Figure 14 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0300] S1401. The first terminal device is currently in a connected state. For a description of the first terminal device being in a connected state, please refer to... Figure 13 Step S1301 shown will not be repeated here.

[0301] S1402, the PCF sends an SM policy association modification request to the SMF. Correspondingly, the SMF receives the SM policy association modification request from the PCF. This SM policy association modification request includes the session policy information of the first terminal device.

[0302] It should be noted that the SM policy association modification request in this embodiment is only... Figure 8 A specific example of the fifth message in the illustrated embodiment, of course, Figure 8 The fifth message in the illustrated embodiment can also be other messages, and this application embodiment does not specifically limit this.

[0303] Optionally, in this embodiment of the application, the PCF can determine whether to allow the first service (such as the above-mentioned vehicle networking service, IMS service, etc.) to occupy the spectrum resources of the first network according to the local configuration.

[0304] The relevant description of the session policy information of the first terminal device obtained by the SMF from the PCF can be found in the following reference. Figure 13 The embodiments shown will not be described in detail here.

[0305] S1403, SMF establishes the first QoS flow of the first PDU session of the first terminal device, and determines whether to allow the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network according to the session policy information of the first terminal device.

[0306] For example, assuming that the session policy information of the first terminal device includes fourth indication information, and the fourth indication information indicates that the session or QoS flow established according to the session policy information of the first terminal device is allowed to occupy the spectrum resources of the first network, then the SMF can determine, according to the session policy information of the first terminal device, that the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0307] Optionally, when the SMF determines whether to allow the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network based on the session policy information of the first terminal device, it may refer to the subscription information of the first terminal device. Relevant examples can be found here. Figure 13 The embodiments shown will not be described in detail here.

[0308] S1404, SMF sends a request to AMF for the N1N2 message transfer service (Namf_Communication_N1N2MessageTransfer service) provided by AMF. Correspondingly, AMF receives the N1N2 message transfer service request from SMF.

[0309] S1405, AMF sends an N2 message to the RAN device. Correspondingly, the RAN device receives the N2 message from the AMF.

[0310] Regarding steps S1404 and S1405 above:

[0311] When the SMF determines that the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network, the N1N2 message transmission service request in step S1404 includes third indication information, and then the N2 message in step S1405 includes the third indication information. The third indication information indicates that the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0312] Optionally, in this embodiment, when the SMF determines that the first QoS flow of the first PDU session of the first terminal device is not allowed to occupy the spectrum resources of the first network, the N1N2 message transmission service request in step S1404 may include eighth indication information, and then the N2 message in step S1406 includes the eighth indication information, which indicates that the first QoS flow of the first PDU session of the first terminal device is not allowed to occupy the spectrum resources of the first network. Of course, the RAN device can also implicitly learn that the network does not allow the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network. For example, when the N2 message does not include third indication information, the RAN device can determine that the network does not allow the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network. This embodiment does not specifically limit this.

[0313] S1406, AMF sends a PDU session modification command to the first terminal device. Correspondingly, the first terminal device receives the PDU session modification command from AMF.

[0314] It should be noted that in this embodiment, steps S1405 and S1406 can be performed simultaneously; or, the PDU session modification command in step S1406 can be included in the N2 message of S1405 and sent to the RAN device, and the RAN device can further send the PDU session modification command to the first terminal device. This embodiment does not specifically limit this.

[0315] Furthermore, in this embodiment of the application, if the N2 message includes third indication information, the spectrum resource sharing method provided in this embodiment of the application further includes the following step S1407:

[0316] S1407, The RAN device occupies the spectrum resources of the first network for the first QoS flow of the first PDU session of the first terminal device.

[0317] The relevant description of the spectrum resources occupied by the first QoS flow of the first PDU session of the first terminal device by the RAN device can be found in [reference]. Figure 8 The embodiments shown will not be described in detail here.

[0318] It should be noted that, in this embodiment, the RAN device can allocate spectrum resources of the first network for the first QoS flow of the first PDU session of the first terminal device according to the third indication information when it determines that the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to a preset threshold. Of course, the RAN device can also directly allocate spectrum resources of the first network for the first QoS flow of the first PDU session of the first terminal device after receiving the N2 message without determining whether the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to the preset threshold. This embodiment does not specifically limit this.

[0319] Figure 14 The technical effects of the embodiments shown can be referred to Figure 8 The embodiments shown will not be described in detail here.

[0320] Among them, the SMF action in steps S1401 to S1407 above can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to execute the instruction SMF. The actions of the RAN device in steps S1401 to S1407 can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the RAN device to execute, and this embodiment does not impose any restrictions on this.

[0321] Combination Figure 9 The method for sharing spectrum resources, in order to Figure 2 The communication system described is applied to, for example Figure 4 Taking the 5G network shown as an example, such as Figure 15 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0322] S1501-S1502, same Figure 12 Steps S1201-S1202 in the illustrated embodiment will not be repeated here.

[0323] S1503, UDM obtains the subscription information of the first terminal device. This subscription information includes information on the first spectrum resource; a description of the first spectrum resource information can be found in [reference needed]. Figure 9 The embodiments shown will not be described in detail here.

[0324] Optionally, the information of the first spectrum resource may also be used to indicate the PLMN ID and / or RAT type corresponding to the first spectrum resource, which is not specifically limited in this embodiment of the application.

[0325] Of course, in this embodiment, the subscription information of the first terminal device may also include some existing subscription information, such as the slice information and / or mobility restriction information of the first terminal device, etc. This embodiment does not specifically limit this.

[0326] In one possible implementation, the subscription information of the first terminal device is pre-configured in the UDR. Furthermore, when the UDM receives a request from the AMF to obtain subscription information, the UDM retrieves the subscription information of the first terminal device from the UDR and stores it in the UDM.

[0327] S1504, UDM sends a Nudm_SDM_Get response to the AMF, which provides a subscription information management service. Correspondingly, the AMF receives the Nudm_SDM_Get response from UDM. This response includes the subscription information of the first terminal device.

[0328] At this point, the AMF can obtain the subscription information of the first terminal device. This subscription information includes information about the first spectrum resource. Optionally, in this embodiment, the UDM can also adjust the information about the first spectrum resource through interaction with the PCF, as shown in steps S1505-S1507:

[0329] S1505, the AMF sends an access and mobility (AM) policy control creation request (Npcf_AM policy control_create request) provided by the PCF to the PCF. Correspondingly, the PCF receives the creation request from the AMF. This creation request includes information about the first spectrum resource.

[0330] S1506, PCF adjusts the information of the first spectrum resource according to the local policy.

[0331] For example, assuming the first spectrum resource information in the subscription information of the terminal device is 1, and the first spectrum resource information is used to indicate the spectrum resource 1 of the first network, the PCF may adjust the first spectrum resource information. The adjusted first spectrum resource information is used to indicate the spectrum resource 2 of the first network (i.e., it is recommended to use another spectrum resource of the first network) or the adjusted first spectrum resource information is used to indicate the spectrum resource 2 of the second network (i.e., it is recommended to use only the spectrum resources of this network).

[0332] S1507, the PCF sends an AM policy control creation response (Npcf_AM policycontrol_create response) to the AMF. Correspondingly, the AMF receives the creation response from the PCF. This creation response includes information about the first spectrum resource or the adjusted information about the first spectrum resource (hereinafter also referred to as the first spectrum resource information).

[0333] Furthermore, in this embodiment of the application, after the AMF obtains the subscription information of the first terminal device, the spectrum resource sharing method provided in this embodiment of the application may further include the following steps:

[0334] S1508, the AMF sends an N2 message to the RAN device. Correspondingly, the RAN device receives the N2 message from the AMF. This N2 message includes information about the first spectrum resource.

[0335] S1509, the AMF sends a registration accept message to the first terminal device. Correspondingly, the first terminal device receives the registration accept message from the AMF.

[0336] S1510, the RAN equipment occupies the first spectrum resource for the first terminal device according to the information of the first spectrum resource.

[0337] For details and examples regarding the RAN equipment occupying the first spectrum resources for the first terminal equipment, please refer to [link / reference]. Figure 9 The embodiments shown will not be described in detail here.

[0338] Optionally, the spectrum resource sharing method provided in this application embodiment further includes: the RAN device storing a first spectrum resource and the correspondence between the PLMN ID and / or RAT type. After determining the first spectrum resource, the RAN device can further determine the PLMN ID and / or RAT type corresponding to the first spectrum resource based on the correspondence between the first spectrum resource and the PLMN ID and / or RAT type. Then, the RAN device can determine that the first spectrum resource belongs to the network corresponding to the PLMN ID, and / or that the first spectrum resource is used for the RAT type. This facilitates the RAN device in statistically analyzing spectrum resource usage from the PLMN ID and / or RAT perspective; this will be explained uniformly here and will not be elaborated further below.

[0339] It should be noted that, in this embodiment of the application, the RAN device may reserve the first spectrum resource for the first terminal device when it determines that the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to a preset threshold. Of course, the RAN device may also, after obtaining the information on the first spectrum resource, reserve the first spectrum resource directly for the first terminal device without determining whether the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to the preset threshold. This embodiment of the application does not specifically limit this.

[0340] Figure 15 The technical effects of the embodiments shown can be referred to Figure 9 The embodiments shown will not be described in detail here.

[0341] Among them, the action of AMF in steps S1501 to S1510 above can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to execute the instruction AMF. The actions of the RAN device in the above steps S1501 to S1510 can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the RAN device to execute, and this embodiment does not impose any restrictions on this.

[0342] Combination Figure 10 The method for sharing spectrum resources, in order to Figure 2 The communication system described is applied to, for example Figure 4 Taking the 5G network shown as an example, such as Figure 16 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0343] S1601-S1602, same Figure 12 Steps S1201-S1202 in the illustrated embodiment will not be repeated here.

[0344] S1603, UDM obtains the subscription information of the first terminal device. This subscription information includes information on the second spectrum resource; a description of the second spectrum resource information can be found in [reference needed]. Figure 10 The embodiments shown will not be described in detail here.

[0345] Of course, in this embodiment, the subscription information of the first terminal device may also include some existing subscription information, such as the slice information and / or mobility restriction information of the first terminal device, etc. This embodiment does not specifically limit this.

[0346] In one possible implementation, the subscription information of the first terminal device is pre-configured in the UDR. Furthermore, when the UDM receives a request from the AMF to obtain subscription information, the UDM retrieves the subscription information of the first terminal device from the UDR and stores it in the UDM.

[0347] Optionally, in this embodiment, the information of the second spectrum resource is also used to indicate the PLMN ID and / or RAT type corresponding to the first spectrum resource. This embodiment does not specifically limit this.

[0348] S1604, UDM sends a Nudm_SDM_Get response to the AMF, which provides a subscription information management service. Correspondingly, the AMF receives the Nudm_SDM_Get response from UDM. This response includes the subscription information of the first terminal device.

[0349] At this point, the AMF can obtain the subscription information of the first terminal device. This subscription information includes information about the second spectrum resource. Optionally, in this embodiment, the UDM can also adjust the information about the second spectrum resource through interaction with the PCF, as shown in steps S1605-S1607:

[0350] S1605, the AMF sends an access and mobility (AM) policy control creation request (Npcf_AM policy control_create request) provided by the PCF to the PCF. Correspondingly, the PCF receives the creation request from the AMF. This creation request includes information about the second spectrum resource.

[0351] S1606, PCF adjusts the information of the second spectrum resource according to the local policy.

[0352] For example, the second spectrum resource information in the subscription information of the terminal device includes a first identifier, which is used to indicate spectrum resource 1 of the first network. Then the PCF may adjust the first identifier, and the adjusted first identifier is used to indicate spectrum resource 2 of the first network (i.e., it is recommended to use another spectrum resource of the first network) or the adjusted first identifier is used to indicate spectrum resource 2 of the second network (i.e., it is recommended to use only the spectrum resources of this network).

[0353] S1607, the PCF sends an AM policy control creation response (Npcf_AM policycontrol_create response) to the AMF. Correspondingly, the AMF receives the creation response from the PCF. This creation response includes information about the second spectrum resource or adjusted information about the second spectrum resource (hereinafter also referred to as the second spectrum resource information).

[0354] Furthermore, in this embodiment of the application, after the AMF obtains the subscription information of the first terminal device, the spectrum resource sharing method provided in this embodiment of the application may further include the following steps:

[0355] S1608, the AMF sends an N2 message to the RAN device. Correspondingly, the RAN device receives the N2 message from the AMF. This N2 message includes information about the second spectrum resource.

[0356] S1609, AMF sends a registration accept message to the first terminal device. Correspondingly, the first terminal device receives the registration accept message from AMF.

[0357] S1610, the RAN equipment occupies the second spectrum resource for the first service of the first terminal equipment according to the information of the second spectrum resource.

[0358] The description and examples of how the RAN equipment uses the second spectrum resource for the first service of the first terminal device, based on the information of the second spectrum resource, can be found in the following reference. Figure 10 The embodiments shown will not be described in detail here.

[0359] Optionally, the spectrum resource sharing method provided in this application embodiment further includes: the RAN device storing the second spectrum resource and the correspondence between the PLMN ID and / or RAT type. After determining the second spectrum resource, the RAN device can further determine the PLMN ID and / or RAT type corresponding to the second spectrum resource based on the correspondence between the second spectrum resource and the PLMN ID and / or RAT type. Then, the RAN device can determine that the second spectrum resource belongs to the network corresponding to the PLMN ID, and / or that the second spectrum resource is used for the RAT type. This facilitates the RAN device in statistically analyzing spectrum resource usage from the PLMN ID and / or RAT dimension, which is explained uniformly here and will not be elaborated further below.

[0360] It should be noted that, in this embodiment, the RAN device can allocate second spectrum resources for the first terminal device's first service based on the second spectrum resource information when it determines that the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to a preset threshold. Of course, the RAN device can also, after obtaining the second spectrum resource information, directly allocate second spectrum resources for the first terminal device's first service without determining whether the spectrum resource demand of the second network subscribed to by the first terminal device is greater than or equal to the preset threshold. This embodiment does not specifically limit this approach.

[0361] Figure 16 The technical effects of the embodiments shown can be referred to Figure 10 The embodiments shown will not be described in detail here.

[0362] Among them, the action of AMF in steps S1601 to S1610 above can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to execute the instruction AMF. The actions of the RAN device in steps S1601 to S1610 above can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the RAN device to execute, and this embodiment does not impose any restrictions on this.

[0363] Combination Figure 11 The method for sharing spectrum resources, in order to Figure 3 The communication system described is applied to, for example Figure 4 Taking the 5G network shown as an example, such as Figure 17 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0364] S1701, The first PDU session of the first terminal device is currently active.

[0365] In this embodiment, the first PDU session of the first terminal device being in an active state means that the first terminal device can transmit and receive data with the UPF on the network side through the first PDU session. Specifically, an N3 interface data transmission channel is established between the UPF and the RAN device for the first PDU session, and an air interface data transmission channel, such as a data radio bearer (DRB), is established between the RAN device and the first terminal device for the first PDU session. Therefore, the first terminal device can transmit and receive data with the UPF on the network side through the N3 interface data transmission channel and the air interface data transmission channel of the first PDU session.

[0366] It should be noted that this application embodiment uses a 5G network as an example for illustration, therefore the first session is the first PDU session. Of course, in other networks in the future, the session can be any session other than a PDU session, and this application embodiment does not specifically limit this.

[0367] S1702, The RAN device determines that the spectrum resource demand of the second network subscribed by the first terminal device is greater than or equal to a preset threshold.

[0368] S1703, the RAN device sends a radio resource usage authorization request to the SMF. Correspondingly, the SMF receives the radio resource usage authorization request from the RAN device. This request includes the session identifier of the first PDU session of the first terminal device and / or the first QoS flow identifier of the first PDU session of the first terminal device.

[0369] It should be noted that the spectrum resource occupancy authorization request in this application embodiment is only... Figure 11 The illustrated embodiment is a specific example of the sixth message. Of course, Figure 11 In the embodiments shown, the sixth message can also be other messages, and this application does not specifically limit this.

[0370] S1704. Based on the subscription information and / or session policy information of the first terminal device, the SMF determines whether to allow the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network.

[0371] The relevant description of step S1704 can be found in [reference]. Figure 13 Step S1304 in the illustrated embodiment will not be repeated here.

[0372] S1705, the SMF sends a radio resource usage authorization response to the RAN device. Correspondingly, the RAN device receives the radio resource usage authorization response from the SMF.

[0373] Optionally, in this embodiment of the application, when the SMF determines that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network, the spectrum resource occupation authorization response includes third indication information, which indicates that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0374] Optionally, in this embodiment of the application, when the SMF determines that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network, the spectrum resource occupation authorization response may also include the duration for which the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0375] Optionally, in this embodiment, when the SMF determines that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is not allowed to occupy the spectrum resources of the first network, the spectrum resource usage authorization response includes an eighth indication information, which indicates that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is not allowed to occupy the spectrum resources of the first network. Of course, the RAN device can also implicitly learn that the network does not allow the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network. For example, when the spectrum resource usage authorization response does not include the third indication information, the RAN device can determine that the network does not allow the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network; or, when the SMF determines that the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is not allowed to occupy the spectrum resources of the first network, the SMF can send a spectrum resource usage authorization reject / failure message to the RAN device. Accordingly, the RAN device receives a spectrum resource occupancy authorization rejection / failure message from the SMF, and determines, based on the spectrum resource occupancy authorization rejection / failure message, whether the network does not allow the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device to occupy the first network spectrum resources. This application embodiment does not specifically limit this.

[0376] Furthermore, in this embodiment of the application, if the spectrum resource occupancy authorization response includes third indication information, the spectrum resource sharing method provided in this embodiment of the application further includes the following step S1706:

[0377] S1706. The RAN device occupies the spectrum resources of the first network for the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device.

[0378] For details and examples regarding the RAN device occupying spectrum resources of the first network for the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device, please refer to [reference needed]. Figure 8 The embodiments shown will not be described in detail here.

[0379] In this embodiment of the application, when the spectrum resource occupancy authorization response includes a duration for which the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device is allowed to occupy the spectrum resources of the first network, when the duration for which the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device occupies the spectrum resources of the first network reaches that duration, the RAN device may no longer allow the first PDU session of the first terminal device or the first QoS flow of the first PDU session of the first terminal device to occupy the spectrum resources of the first network, thereby achieving effective control over the spectrum resource occupancy of different networks.

[0380] Figure 17 The technical effects of the embodiments shown can be referred to Figure 11 The embodiments shown will not be described in detail here.

[0381] Among them, the SMF action in steps S1701 to S1706 above can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to execute the instruction SMF. The actions of the RAN device in steps S1701 to S1706 above can be performed by... Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to instruct the RAN device to execute, and this embodiment does not impose any restrictions on this.

[0382] Combination Figure 6 or Figure 7 The method for sharing spectrum resources, in order to Figure 2 The communication system described is applied to, for example Figure 4 Taking the 5G network shown as an example, such as Figure 18 As shown, another method for spectrum resource sharing provided in this application embodiment is described below.

[0383] S1801-S1802, same Figure 17 Steps S1701-S1702 in the illustrated embodiment will not be repeated here.

[0384] S1803. The RAN device sends a radio resource usage authorization request to the AMF. Correspondingly, the AMF receives the radio resource usage authorization request from the RAN device.

[0385] It should be noted that the spectrum resource occupancy authorization request in this application embodiment is only... Figure 6 The second message or in the embodiment shown Figure 7 The illustrated embodiment is a specific example of the fourth message. Of course, Figure 6 The second message or in the embodiment shown Figure 7 In the embodiments shown, the fourth message can also be other messages, and this application does not specifically limit this.

[0386] S1804. Based on the subscription information of the first terminal device, the AMF sends a radio resource usage authorization response to the RAN device. Correspondingly, the RAN device receives the radio resource usage authorization response from the AMF.

[0387] The description of the contract information of the first terminal device and the method of obtaining such contract information can be found in the following reference. Figure 12 The embodiments shown will not be described in detail here.

[0388] In one possible implementation, when the subscription information of the first terminal device includes the aforementioned first information, the AMF can determine the permitted spectrum resources of the first network for the first terminal device to occupy based on at least one of the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network. A related description can be found in [reference needed]. Figure 6 The aforementioned embodiments will not be repeated here. Furthermore, the above-mentioned spectrum resource occupancy authorization response includes first indication information, which indicates that the first terminal device is permitted to occupy the spectrum resources of the first network.

[0389] In another possible implementation, when the subscription information of the first terminal device includes at least one of the first information, the fourth information, or the identification information of the first service of the first terminal device, the AMF can determine the spectrum resources of the first network that the first service of the first terminal device is allowed to occupy based on at least one of the subscription information of the first terminal device, the access and mobility control policy information of the first terminal device, or the local policy information of the second network. A related description can be found in [reference needed]. Figure 7The aforementioned embodiments will not be repeated here. Further, the spectrum resource occupancy authorization response includes second indication information, which indicates that the first terminal device's first service is permitted to occupy the spectrum resources of the first network. For example, the second indication information includes indication information allowing the first terminal device's first service to occupy the spectrum resources of the first network and identification information of the first terminal device's first service permitted to occupy the spectrum resources of the first network.

[0390] Optionally, when the AMF determines that the first terminal device or the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, the above spectrum resource occupation authorization response may also include the duration for which the first terminal device or the first service of the first terminal device is allowed to occupy the spectrum resources of the first network.

[0391] Optionally, when the AMF determines that the first terminal device is not allowed to occupy the spectrum resources of the first network, the spectrum resource usage authorization response includes a seventh indication, which indicates that the first terminal device is not allowed to occupy the spectrum resources of the first network. Of course, the RAN device can also implicitly learn that the network does not allow the first terminal device to occupy the spectrum resources of the first network. For example, when the spectrum resource usage authorization response does not include the first or second indication, the RAN device can determine that the network does not allow the first terminal device to occupy the spectrum resources of the first network; or, when the AMF determines that the first terminal device is not allowed to occupy the spectrum resources of the first network, the AMF can send a radio resource usage authorization reject / failure message to the RAN device. Accordingly, the RAN device receives the radio resource usage authorization reject / failure message from the AMF and determines, based on the message, that the network does not allow the first terminal device to occupy the spectrum resources of the first network. This embodiment of the application does not specifically limit this.

[0392] Furthermore, in this embodiment of the application, if the spectrum resource occupancy authorization response includes the first indication information or the second indication information, the spectrum resource sharing method provided in this embodiment of the application further includes the following step S1805:

[0393] S1805, RAN equipment occupies the first network spectrum resources for the first terminal equipment or the first service of the first terminal equipment.

[0394] In this embodiment of the application, when the spectrum resource occupancy authorization response includes a duration for which the first terminal device or the first service of the first terminal device is allowed to occupy the spectrum resources of the first network, when the duration for which the first terminal device or the first service of the first terminal device occupies the spectrum resources of the first network reaches that duration, the RAN device may no longer allow the first terminal device or the first service of the first terminal device to occupy the spectrum resources of the first network, thereby achieving effective control over the spectrum resource occupancy of different networks.

[0395] In this embodiment of the application, when the spectrum resource occupancy authorization response includes first indication information, the RAN device can, based on the first indication information, occupy spectrum resources of the first network for the first terminal device. Related descriptions and examples can be found in the following references. Figure 6 The embodiments shown will not be described in detail here.

[0396] In this embodiment of the application, when the spectrum resource occupancy authorization response includes second indication information, the RAN device can, according to the second indication information, occupy spectrum resources of the first network for the first service of the first terminal device. Related descriptions and examples can be found in the following references. Figure 7 The embodiments shown will not be described in detail here.

[0397] Figure 18 The technical effects of the embodiments shown can be referred to Figure 5 or Figure 6 The embodiments shown will not be described in detail here.

[0398] Among them, the actions of AMF in steps S1801 to S1805 above can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 to execute the instruction AMF.
