[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

[0039] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] After analysis, it is found that if the terminal supports connecting to the core network through two independent 3GPP radio access networks at the same time, the advantages of the two independent radio access networks can be used to provide stronger network control capabilities. However, when the terminal supports two independent 3GPP radio access networks at the same time, the problem of connection management needs to be solved, for example, how to optimize the connection management to utilize the network characteristics of the two different radio accesses to improve the communication quality of the terminal.

[0044] In order to at least solve the above technical problems, the present invention proposes a connection management optimization solution when a terminal is registered to two independent 3GPP wireless networks. When the terminal has downlink services in one wireless access network and is in an idle state, the network can page or notify the terminal through another wireless access network, or through two wireless access networks at the same time, so that the terminal returns to a connected state in at least one wireless access network and completes the downlink service in one of the wireless access networks. Figure 1, an embodiment of the wireless access control method of the present invention is described from the core network side, that is, the embodiment is executed by the device on the core network side.

[0045] Figure 1 FIG. 2 is a flow chart showing a method for controlling wireless access according to some embodiments of the present invention. Figure 1 As shown, the wireless access control method of this embodiment includes steps S102 to S110.

[0046] In step S102, a downlink service corresponding to the terminal is obtained. When carrying the downlink service, the first wireless access network of the core network has a higher priority than the second wireless access network of the core network. That is, on the core network side, the bearer strategy is to give priority to using the first wireless access network to carry the downlink service. However, the bearer strategy of the core network is only a reference. According to the actual network conditions and the bearer strategy on the terminal side, the second wireless access network can actually be used to carry the downlink service.

[0047] In some embodiments, the first wireless access network is a non-terrestrial network (Non-Terrestrial Network, abbreviated as: NTN), and the second wireless access network is a terrestrial network (Terrestrial Network, abbreviated as: TN).

[0048] When the terminal is in an idle state in the first radio access network, it may not be possible to directly carry downlink services through the first radio access network. At this time, there may be three processing methods shown in steps S104 to S108, and any one of them may be executed. For example, one of the processing methods may be selected for execution according to the state of the terminal in the second radio access network.

[0049] In step S104, the terminal is notified through the second radio access network. For example, when the terminal is in a connected state on the second radio access network, the terminal is notified through the second radio access network, i.e., step S104 is executed. Thus, when the terminal has a downlink service, if the terminal is in an idle state on the first radio access network with a higher priority on the core network side, but is in a connected state on another radio access network (i.e., the second radio access network), the second radio access network can be directly used to notify the terminal, so that the terminal is informed of the downlink service as soon as possible, thereby reducing the downlink service delay of the terminal.

[0050] The notification sent to the terminal through the second radio access network may include the bearer strategy of the core network, that is, information that the first radio access network has a higher priority than the second radio access network for downlink services. Thus, the terminal can learn relevant information about the downlink service after receiving the notification.

[0051] In step S106, the terminal is paged through the second radio access network. In this way, the core network only pages the terminal through the second radio access network, that is, not through the first radio access network. For example, when the terminal is in an idle state in the second radio access network, the terminal is paged through the second radio access network, that is, step S106 is executed. The paging of the terminal through the second radio access network may include the bearer strategy of the core network, that is, for downlink services, the priority of the first radio access network is higher than the information of the second radio access network. Thus, the terminal can understand the relevant information of the downlink service after obtaining the notification.

[0052] During the process of the second wireless access network notifying or paging the terminal, if the terminal senses that the first wireless access network is available through other means, the terminal can make further decisions based on the bearer strategy of the core network and / or the bearer strategy of the terminal to choose whether to carry the downlink service through the first wireless access network or the second wireless access network.

[0053] In step S108, the terminal is paged through the first radio access network and the second radio access network. For example, when the terminal is in an idle state on the second radio access network, the terminal is paged through the first radio access network and the second radio access network, that is, step S108 is executed. The paging of the terminal through the first radio access network and the second radio access network can include the bearer strategy of the core network, that is, for downlink services, the priority of the first radio access network is higher than the information of the second radio access network. Therefore, the terminal can understand the relevant information of the downlink service after obtaining the notification.

[0054] The method of jointly performing paging through the first radio access network and the second radio access network can improve the success rate and delay of paging and reduce the delay of the downlink service of the terminal.

[0055] Figure 2A and Figure 2B The schematic diagram exemplarily shows a scenario in which the core network performs paging / notification on a terminal.

[0056] exist Figure 2A In the present invention, when the terminal has a downlink service, even if the downlink service is associated with the first radio access network, that is, using the first radio access network to carry the downlink service has a higher priority, the network side can also perform paging / notification only through the second radio access network according to the actual network attributes.

[0057] exist Figure 2B In the present invention, when the terminal has a downlink service, and the downlink service is associated with the first radio access network, that is, when the first radio access network has a higher priority in carrying the downlink service, the terminal can also be paged through the first radio access network and the second radio access network at the same time. This can improve the success rate of paging and reduce the network delay of the downlink service.

[0058] When the terminal is in an idle state in the second radio access network, the specific method can also be selected according to the network attributes. In some embodiments, according to the network attributes of the first radio access network and the second radio access network, the terminal is paged through the second radio access network, or the terminal is paged through the first radio access network and the second radio access network. For example, the network attribute can be channel quality. When the channel quality of the second radio access network is higher than that of the first radio access network, the terminal is paged through the second radio access network of the core network. Of course, as needed, when the channel quality of the second radio access network is higher than that of the first radio access network, the terminal can also be paged jointly through the first radio access network and the second radio access network.

[0059] In the case that the channel quality of the second radio access network is not higher than that of the first radio access network, the terminal may be paged jointly through the first radio access network and the second radio access network.

[0060] Therefore, when the channel quality of the radio access network with a lower priority is higher, the radio access network with a higher channel quality can be used to paging the terminal to reduce the network delay of the downlink service.

[0061] The above embodiment provides a network control solution when a terminal has dual wireless access. In this solution, when the first wireless access network carries a higher priority of downlink services, when the terminal is in an idle state on the first wireless access network, the terminal can be paged or notified through the second wireless access network. Thus, the embodiment of the present invention can reduce the downlink service delay of the terminal.

[0062] Reference below Figure 3 , an embodiment of the wireless access control method of the present invention is described from the terminal side.

[0063] Figure 3 FIG. 2 is a flow chart showing a method for controlling wireless access according to some embodiments of the present invention. Figure 3 As shown, the wireless access control method of this embodiment includes steps S302 to S308.

[0064] When the terminal is in an idle state in the first radio access network of the core network, steps S302 to S306 are selectively executed according to the decision of the core network side, and the specific implementation method thereof may refer to the aforementioned embodiment.

[0065] In step S302, the terminal receives a notification from the core network via the second radio access network of the core network.

[0066] In step S304, the terminal receives paging from the core network through the second radio access network.

[0067] In step S306, the terminal receives paging from the core network through the first radio access network and the second radio access network.

[0068] In step S308, a radio access network for carrying downlink services of the terminal is selected from the radio access networks to which the terminal can connect.

[0069] If the terminal is in an idle state in a certain radio access network, as long as the radio access network is reactivated, the radio access network can also be used to carry downlink services. Therefore, a radio access network that can be connected, such as a radio access network with signal coverage, can be selected to carry downlink services. If a radio access network does not cover the location of the terminal, the terminal cannot be used, that is, it cannot be connected, and the radio access network cannot be selected by the terminal to carry downlink services.

[0070] In some embodiments, the terminal may select a radio access network for carrying the downlink service of the terminal according to at least one of the terminal's bearer policy and the core network's bearer policy. For example, the terminal's bearer policy may also set the priority of the first radio access network and the second radio access network, or the priority of the first radio access network and the second radio access network under specified conditions, etc. The specified conditions may include, for example, the content of the core network's bearer policy, which will not be repeated here.

[0071] After the terminal makes the selection, the terminal may send a notification to the core network through the selected radio access network to adopt the selected radio access network to bear the downlink service.

[0072] Through the above embodiment, when the first radio access network has a higher priority for carrying downlink services, when the terminal is in an idle state in the first radio access network, the terminal can receive paging or notification from the core network through the second radio access network. Thus, the embodiment of the present invention can reduce the downlink service delay of the terminal.

[0073] The following are references Figure 4 and Figure 5 Describe the signaling interaction process between the terminal and the core network.

[0074] Figure 4 FIG. 4 shows a signaling flow chart of wireless access control according to some embodiments of the present invention. Figure 4 As shown, the signaling process of the wireless access control in this embodiment includes steps S402 to S414.

[0075] In step S402, the terminal registers with the core network through the first radio access network and establishes a protocol data unit (PDU) session.

[0076] In step S404, the terminal registers with the core network through the second radio access network and establishes a PDU session.

[0077] In step S406, the core network receives downlink services, wherein the downlink services are associated with the first radio access network and are preferentially carried by the first radio access network, that is, for the downlink services, the priority of the first radio access network is higher than that of the second radio access network.

[0078] In step S408, the core network initiates paging or notification through the second radio access network.

[0079] In step S410, the terminal selects a radio access network that carries the downlink service. Then, the terminal notifies the core network to carry the downlink service through the selected radio access network, that is, executes one of steps S412 and S414. The notification sent by the terminal to the core network may be a service request message.

[0080] In step S412, the terminal notifies the core network to carry the downlink service through the first radio access network.

[0081] In step S414, the terminal notifies the core network to carry the downlink service through the second radio access network.

[0082] Figure 5 FIG. 2 shows a signaling flow chart of wireless access control according to some other embodiments of the present invention. Figure 5 As shown, the signaling process of the wireless access control in this embodiment includes steps S502 to S514.

[0083] In step S502, the terminal registers with the core network through the first radio access network and establishes a PDU session.

[0084] In step S504, the terminal registers with the core network through the second radio access network and establishes a PDU session.

[0085] In step S506, the core network receives downlink services, wherein the downlink services are associated with the first radio access network and are preferentially carried by the first radio access network, that is, for the downlink services, the priority of the first radio access network is higher than that of the second radio access network.

[0086] In step S5082, the core network initiates paging through the second radio access network.

[0087] In step S5084, the core network initiates paging through the first radio access network.

[0088] In step S510, the terminal selects a radio access network for carrying downlink services. Then, the terminal notifies the core network to carry the downlink services through the selected radio access network, that is, executing one of steps S512 and S514.

[0089] In step S512, the terminal notifies the core network to carry the downlink service through the first radio access network.

[0090] In step S514, the terminal notifies the core network to carry the downlink service through the second radio access network.

[0091] Through the above embodiment, when the first radio access network has a higher priority in carrying downlink services, when the terminal is in an idle state in the first radio access network, the second radio access network can be used to page or notify the terminal. Thus, the embodiment of the present invention can reduce the downlink service delay of the terminal.
