Description

Technical Field

[0001] Embodiments of the present application relate to the field of communication technologies, and in particular, to an information transmission method, apparatus, and storage medium. Background Art

[0002] Currently, an access network device can perform positioning measurement on a positioning signal sent by a terminal device according to a request message. After that, if the positioning signal sent by the terminal device changes, the access network device needs to obtain a measurement update message from the location management function (LMF) side in order to continue performing positioning measurement on the positioning signal sent by the terminal device according to the measurement update message. This easily delays the access network device from performing positioning measurement on the positioning signal sent by the terminal device. Summary of the Invention

[0003] Embodiments of the present application provide an information transmission method, apparatus, and storage medium, which can enable an access network device to perform positioning measurement corresponding to a terminal device in a timely manner.

[0004] In a first aspect, an information transmission method is provided. This method can be executed by an access network device, or by a component of the access network device, such as a processor, chip, or chip system of the access network device, or can also be implemented by a logic module or software that can implement all or part of the access network device. The following takes the case where this method is executed by an access network device as an example for description. The information transmission method includes: receiving a first request message from a location management function network element, where the first request message is used to request positioning signal configuration information of a terminal device, and the first request message carries first information. The first information is used to identify the positioning measurement corresponding to the terminal device, and the positioning measurement corresponding to the terminal device is the positioning measurement performed by the access network device on the positioning signal sent by the terminal device.

[0005] In embodiments of the present application, the access network device can learn about the positioning measurement corresponding to the terminal device through the first information carried in the first request message. Since there is a corresponding relationship between the terminal device and the positioning measurement, the access network device can directly perform positioning measurement on the positioning signal sent by the terminal device. If the positioning signal of the terminal device changes subsequently, the access network device can also directly continue to perform positioning measurement on the signal sent by the terminal device according to the corresponding relationship between the terminal device and the positioning measurement, eliminating the operation of transmitting a measurement update message between the access network device and the location management function network element, so that the access network device can perform positioning measurement corresponding to the terminal device in a timely manner, thereby avoiding delaying the access network device from performing positioning measurement corresponding to the terminal device.

[0006] Combined with the above first aspect, in a possible implementation manner, the method provided by the embodiments of the present application further includes: when the positioning signal sent by the terminal device changes, performing positioning measurement corresponding to the terminal device on the changed positioning signal sent by the terminal device.

[0007] That is to say, when the positioning signal sent by the terminal device changes, the access network device can directly perform positioning measurement corresponding to the terminal device on the changed positioning signal sent by the terminal device, rather than performing positioning measurement corresponding to the terminal device on the positioning signal sent by the terminal device before the change. This not only saves the operation of transmitting measurement update messages between the access network device and the positioning management function network element, but also avoids the influence of invalid positioning signals on the positioning measurement result, thereby ensuring the accuracy of the positioning measurement result obtained by the access network device.

[0008] Combined with the above first aspect, in a possible implementation manner, the first information includes an identifier of the positioning measurement corresponding to the terminal device.

[0009] Since the above request message is used to request the configuration information of the positioning signal sent by the terminal device, the above request message is a message related to the terminal device. And the first information can be carried in the request message. That is to say, the first information is also information related to the terminal device. Therefore, in this case, the first information including the identifier of the positioning measurement corresponding to the terminal device can enable the access network device to know that the positioning measurement is the positioning measurement corresponding to the terminal device after receiving the request message.

[0010] Combined with the above first aspect, in a possible implementation manner, the positioning signal is a sounding reference signal SRS.

[0011] That is to say, the information transmission method described in the embodiments of the present application can also be applied to the scenario of SRS measurement.

[0012] Combined with the above first aspect, in a possible implementation manner, the first request message is a positioning information request message.

[0013] Since the positioning information request message is a message interacted in the SRS measurement process, in the case where the first request message is a positioning information request message, it can be indicated that the information transmission method described in the embodiments of the present application can also be applied to the scenario of SRS measurement.

[0014] Combined with the above first aspect, in a possible implementation manner, the method provided by the embodiments of the present application further includes: receiving a second request message from the positioning management function network element, where the second request message is used to request the access network device to perform positioning measurement corresponding to the terminal device, and the second request message carries the first information.

[0015] In this implementation manner, the second request message also carries the first information, so that the access network device can associate the first request message and the second request message through the first information. If a request message changes, the access network device can determine the other request message according to the association relationship between the first request message and the second request message, and make an adaptive modification to the other request message, so that the changes of the first request message and the second request message can be kept synchronized, thereby avoiding confusion during the positioning measurement process of the access network device.

[0016] Combined with the first aspect above, in a possible implementation manner, the second request message is a measurement request message.

[0017] Since the measurement request message is a message interacted in the SRS measurement process, in the case where the second request message is a measurement request message, it can be indicated that the information transmission method described in the embodiments of the present application can also be applied to the scenario of SRS measurement.

[0018] In a second aspect, an information transmission method is provided. This method can be executed by a positioning management function network element, or by components of a positioning management function network element, such as a processor, a chip, or a chip system of a positioning management function network element, etc., and can also be implemented by a logic module or software that can implement all or part of the positioning management function network element. The following takes the case where this method is executed by a positioning management function network element as an example for description. The information transmission method includes: sending a first request message to an access network device, where the first request message is used to request positioning signal configuration information of a terminal device, and the request message carries the first information. The first information is used to identify the positioning measurement corresponding to the terminal device, and the positioning measurement corresponding to the terminal device is the positioning measurement performed by the access network device on the positioning signal sent by the terminal device.

[0019] Combined with the second aspect above, in a possible implementation manner, the first information includes an identifier of the positioning measurement corresponding to the terminal device.

[0020] Combined with the second aspect above, in a possible implementation manner, the positioning signal is a sounding reference signal SRS.

[0021] Combined with the second aspect above, in a possible implementation manner, the first request message is a positioning information request message.

[0022] Combined with the second aspect above, in a possible implementation manner, the method provided in the embodiments of the present application further includes: sending a second request message to the access network device, where the second request message is used to request the access network device to perform a positioning measurement corresponding to the terminal device, and the second request message carries the first information.

[0023] Combined with the second aspect above, in a possible implementation manner, the second request message is a measurement request message.

[0024] Among them, for the beneficial effects of the above second aspect and possible implementation manners of the second aspect, reference may be made to the beneficial effects of the above first aspect and possible implementation manners of the first aspect, which will not be elaborated herein.

[0025] In a third aspect, an information transmission method is provided. This method can be executed by an access network device, or by components of the access network device, such as a processor, a chip, or a chip system of the access network device, etc., or can also be implemented by a logic module or software that can implement all or part of the access network device. The following takes the example that this method is executed by the access network device for illustration. The information transmission method includes: receiving a second request message from a positioning management function network element, where the second request message is used to request the access network device to perform positioning measurement, and the measurement request message carries second information. The second information is used to indicate the terminal device corresponding to the positioning measurement, and the positioning measurement is the positioning measurement performed by the access network device on the positioning signal sent by the terminal device.

[0026] In the embodiments of the present application, the access network device can know the terminal device corresponding to the positioning measurement through the second information carried in the second request message. Since there is a corresponding relationship between the terminal device and the positioning measurement, the access network device can directly perform positioning measurement on the positioning signal sent by the terminal device. If the positioning signal of the subsequent terminal device changes, the access network device can also directly continue to perform positioning measurement on the signal sent by the terminal device according to the corresponding relationship between the terminal device and the positioning measurement, eliminating the operation of transmitting a measurement update message between the access network device and the positioning management function network element, so that the access network device can perform the positioning measurement corresponding to the terminal device in a timely manner, thereby avoiding delaying the positioning measurement of the terminal device by the access network device.

[0027] Combined with the above third aspect, in a possible implementation manner, the method provided in the embodiments of the present application further includes: performing positioning measurement on the changed positioning signal sent by the terminal device when the positioning signal sent by the terminal device changes.

[0028] Combined with the above third aspect, in a possible implementation manner, the second information includes an identifier or an associated identifier of the terminal device.

[0029] Since the above second request message is used to request the access network device to perform positioning measurement, the above second request message is a message related to the positioning measurement. The second information can be carried in the measurement request message, that is to say, the second information is also information related to the positioning measurement, and the associated identifier can associate the positioning measurement and the terminal device. Therefore, in this case, the second information including the identifier or the associated identifier of the terminal device can enable the access network device to know that the positioning measurement is the positioning measurement corresponding to the terminal device after receiving the measurement request message.

[0030] Combined with the above third aspect, in a possible implementation, the positioning signal is the sounding reference signal SRS.

[0031] Combined with the above third aspect, in a possible implementation, the second request message is a measurement request message.

[0032] Combined with the above third aspect, in a possible implementation, before receiving the second request message from the positioning management function network element, the method provided by the embodiments of the present application further includes: sending a positioning information response message to the positioning management function network element, where the positioning information response message is used to indicate the positioning signal configuration information of the terminal device, and the positioning information response message carries the second information.

[0033] That is to say, the access network device can pre-inform the positioning management function network element of the second information, so that the subsequent positioning management function network element can carry the second information in the measurement request message. In addition, since the positioning information response message is a message exchanged in the SRS measurement process, when the second information is carried in the positioning information response message, it can indicate that the information transmission method described in the embodiments of the present application can also be applied to the SRS measurement scenario.

[0034] Fourth aspect, an information transmission method is provided. This method can be executed by the positioning management function network element, or by components of the positioning management function network element, such as the processor, chip, or chip system of the positioning management function network element, etc., and can also be implemented by a logic module or software that can implement all or part of the positioning management function network element. The following takes the example that this method is executed by the positioning management function network element for description. The information transmission method includes: sending a second request message to the access network device, where the second request message is used to request the access network device to perform positioning measurement, and the measurement request message carries the second information. The second information is used to indicate the terminal device corresponding to the positioning measurement, and the positioning measurement is a measurement based on the positioning signal sent by the terminal device.

[0035] Combined with the above fourth aspect, in a possible implementation, the second information includes the identifier or associated identifier of the terminal device.

[0036] Combined with the above fourth aspect, in a possible implementation, the positioning signal is the sounding reference signal SRS.

[0037] Combined with the above fourth aspect, in a possible implementation, the second request message is a measurement request message.

[0038] Combined with the above fourth aspect, in a possible implementation manner, before sending the second request message to the access network device, the method provided by the embodiments of the present application further includes: receiving a positioning information response message from the access network device, where the positioning information response message is used to indicate the positioning signal configuration information of the terminal device, and the positioning information response message carries second information.

[0064] To facilitate understanding of the technical solutions provided by the embodiments of the present application, a brief introduction to the related technologies of the present application is first given. The brief introduction is as follows:

[0065] 1. Location measurement technology: It refers to the technology that performs location measurement through the communication between user equipment (UE) and access network equipment to solve information such as the location of the UE or the relative location between UEs.

[0066] Taking the fifth-generation mobile communication technology (5G) network as an example: The UE in the 5G network can be used to send location signals. The access network equipment in the 5G network can measure the location signals sent by the UE, obtain the location measurement results, and send the above location measurement results to the 5G core network (5GC) in the 5G network. Among them, 5GC can include LMF and access and mobility management function (AMF). AMF provides a communication tunnel for LMF and access network equipment, while LMF is used to control the location measurement process of access network equipment and process the reported location measurement results to obtain the location information of the UE.

[0067] As Figure 1 shown, in various embodiments of the present application, the location measurement process may specifically include the following steps:

[0068] S101. The LMF sends a position information request message to the access network equipment through the access and mobility management function (AMF). Correspondingly, the access network equipment receives the position information request message from the LMF through the AMF.

[0069] Among them, the position information request message is used to request the sounding reference signal (SRS) configuration information of the UE.

[0070] Specifically, the LMF sends a position information request message to the AMF. Correspondingly, the AMF receives the position information request message from the LMF. The AMF sends a downlink UE associated radio access network application part (NRPPA) transport message to the access network equipment. Correspondingly, the access network equipment receives the downlink UE associated NRPPA transport message from the AMF. Among them, the downlink UE associated NRPPA transport message carries the position information request message.

[0071] It should be noted that since the NRPPA transmission message associated with the downlink UE carries identification information that can be used to identify the UE, for example, the LMF UE next generation access protocol (NGAP) identification information, or the AMF UE NGAP identification information, the NRPPA transmission message associated with the downlink UE is a message related to the UE.

[0072] S102. The access network device configures SRS configuration information for the UE.

[0073] In some examples, the above SRS configuration information may include at least one of the following: bandwidth, frequency point, subcarrier spacing, or period. Of course, the above is only an exemplary description of the SRS configuration information, and the SRS configuration information may also include other information, and this application does not make any restrictions in this regard.

[0074] S103. The access network device sends a positioning information response message to the LMF through the AMF. Correspondingly, the LMF receives the positioning information response message from the access network device through the AMF.

[0075] Among them, the positioning information response message includes the SRS configuration information of the UE.

[0076] Specifically, the access network device sends an uplink UE associated NRPPA transport message to the AMF. Correspondingly, the AMF receives the uplink UE associated NRPPA transport message from the access network device. Among them, the uplink UE associated NRPPA transport message carries the positioning information response message. The AMF sends the positioning information response message to the LMF. Correspondingly, the LMF receives the positioning information response message from the AMF.

[0077] It should be noted that since the uplink UE associated NRPPA transport message carries identification information for identifying the UE, for example, the LMF UE NGAP identification information, or the AMF UE NGAP identification information, the uplink UE associated NRPPA transport message is a message related to the UE.

[0078] S104. The LMF sends a measurement request message to the access network device through the AMF. Correspondingly, the access network device receives the measurement request message from the LMF through the AMF.

[0079] Among them, the measurement request message is used to instruct the access network device to perform positioning measurement, and the positioning measurement is the positioning measurement performed on the SRS.

[0080] Specifically, the LMF sends a measurement request message to the AMF. Correspondingly, the AMF receives the measurement request message from the LMF. The AMF sends a downlink non UE associated NRPPA transport message to the access network device. Correspondingly, the access network device receives the downlink non UE associated NRPPA transport message from the AMF. Among them, the downlink non UE associated NRPPA transport message carries the measurement request message.

[0081] It should be noted that since the downlink non UE associated NRPPA transport message does not carry the identification information that can be used to identify the UE, the downlink non UE associated NRPPA transport message is a message unrelated to the UE.

[0082] S105. The access network device sends a measurement response message to the LMF through the AMF. Correspondingly, the LMF receives the measurement response message from the access network device through the AMF.

[0083] Among them, the measurement response message includes the above-mentioned positioning measurement result.

[0084] Specifically, the access network device sends an uplink non UE associated NRPPA transport message to the AMF. Correspondingly, the AMF receives the uplink non UE associated NRPPA transport message from the access network device. Among them, the uplink non UE associated NRPPA transport carries the measurement response message. The AMF sends a measurement response message to the LMF. Correspondingly, the LMF receives the measurement response message from the AMF.

[0085] It should be noted that since the uplink non UE associated NRPPA transport message does not carry the identification information that can be used to identify the UE, the uplink non UE associated NRPPA transport message is a message unrelated to the UE.

[0086] S106. The LMF processes the positioning measurement result to obtain the location information of the UE.

[0087] However, the SRS configuration information of the UE is likely to change. For example, when the serving cell of the UE switches from cell 1 to cell 2, the access network device needs to reconfigure new SRS configuration information for the UE, that is, the SRS configuration information of the UE changes. If the SRS configuration information of the UE changes, taking the 5G network as an example, as Figure 2 shown, in various embodiments of the present application, the positioning measurement update process may include the following steps:

[0088] S201. The access network device sends a positioning information update message to the LMF through the AMF. Correspondingly, the LMF receives the positioning information update message from the access network device through the AMF.

[0089] The positioning information update message is used to indicate the new SRS configuration information configured by the access network device for the UE.

[0090] Exemplarily, assume that the serving cell of the UE switches from cell 1 to cell 2: The new SRS configuration information may include the SRS configuration information configured by the access network device for the UE resident in cell 2.

[0091] S202. The LMF sends a measurement update message to the access network device through the AMF. Correspondingly, the access network device receives the measurement update message from the LMF through the AMF.

[0092] The measurement update message is used to indicate that the access network device continues positioning measurement based on the new SRS configuration information.

[0093] Specifically, the LMF sends a measurement update message to the AMF. Correspondingly, the AMF receives the measurement update message from the LMF. The AMF sends a measurement update message to the access network device. Correspondingly, the access network device receives the measurement update message from the AMF.

[0094] It should be noted that since the measurement update message does not carry the identification information for identifying the UE, and the message carrying the measurement update message also does not carry the identification information that can be used to identify the UE, the measurement update message is a message unrelated to the UE.

[0095] S203. The access network device continues positioning measurement based on the new SRS configuration information.

[0096] As can be seen from the foregoing introduction to the "positioning measurement technology", the access network device can perform positioning measurement on the positioning signal according to a request message (for example, a measurement request message). However, since the measurement request message is a message independent of the UE, the access network device cannot associate the terminal device with the positioning measurement, resulting in the access network device being unable to know that the positioning measurement is performed on the positioning signal sent by the terminal device. If the positioning signal sent by the terminal device changes subsequently, the access network device can only obtain a measurement update message from the LMF side and then continue to perform positioning measurement on the positioning signal sent by the terminal device according to the measurement update message, which is likely to delay the positioning measurement of the positioning signal sent by the terminal device by the access network device.

[0097] Based on this, the present application provides an information transmission method. The access network device can learn about the positioning measurement corresponding to the terminal device through the first information carried in the first request message. Since there is a corresponding relationship between the terminal device and the positioning measurement, the access network device can directly perform positioning measurement on the positioning signal sent by the terminal device. If the positioning signal of the terminal device changes subsequently, the access network device can also directly continue to perform positioning measurement on the signal sent by the terminal device according to the corresponding relationship between the terminal device and the positioning measurement, eliminating the operation of transmitting a measurement update message between the access network device and the positioning management function network element, so that the access network device can perform the positioning measurement corresponding to the terminal device in a timely manner, thereby avoiding delaying the positioning measurement of the terminal device by the access network device.

In the embodiments of the present application, for the convenience of description, when referring to numbers, they can be numbered continuously starting from 1, or starting from 0, or starting from any parameter. It should be understood that the above are all settings for facilitating the description of the technical solutions provided by the embodiments of the present application, rather than for limiting the scope of the embodiments of the present application.

[0099] 2. "Pre-defined" or "pre-configured" can be implemented by pre-saving corresponding codes, tables or other means that can be used to indicate relevant information in a device (for example, an access network device or a positioning management function network element). The embodiments of the present application do not limit the specific implementation manner thereof. Herein, "saving" may mean saving in one or more memories. One or more memories may be set separately, or integrated in an encoder or decoder, a processor, or a communication device. One or more memories may also be partially set separately and partially integrated in a decoder, a processor, or a communication device. The type of the memory may be any form of storage medium, and the embodiments of the present application do not limit this.

In the embodiments of the present application, descriptions such as "when...", "in the case of...", "if", and "when" all refer to the situation where the device (for example, an access network device or a positioning management function network element) will perform corresponding processing under certain objective circumstances, rather than limiting time. Moreover, it is not required that the device (for example, an access network device or a positioning management function network element) must have a judgment action during implementation, nor does it mean that there are other limitations.

For example, A / B may represent A or B. The "and / or" in the embodiments of the present application is merely a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. Here, A and B can be singular or plural. Also, in the description of the embodiments of the present application, unless otherwise specified, "a plurality of" means two or more than two. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of a single item or plural items. For example, at least one (item) of a, b, or c may represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple. Additionally, for the convenience of clearly describing the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and roles. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and "first", "second", etc. do not necessarily mean different. At the same time, in the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions.

Alternatively, the communication system can also be a non-3GPP communication system, without limitation.

[0104] In addition, the communication architecture and service scenarios described in the embodiments of the present application are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. As can be known to those of ordinary skill in the art, with the evolution of the communication architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0105] As Figure 3 shown, it is a schematic structural diagram of a communication system provided by an embodiment of the present application. The communication system 300 includes an access network device 301 and a positioning management function network element 302. Optionally, the communication system 300 may further include an access and mobility management function network element 303, and the access network device 301 and the positioning management function network element 302 may communicate through the access and mobility management function network element 303.

[0106] In a possible implementation manner, the positioning management function network element 302 sends a first request message to the access network device 301, and the access network device 301 receives the first request message from the positioning management function network element 302. The first request message is used to request the positioning signal configuration information of the terminal device, and the first request message carries first information. The first information is used to identify the positioning measurement corresponding to the terminal device, and the positioning measurement corresponding to the terminal device is the positioning measurement performed by the access network device on the positioning signal sent by the terminal device. The specific implementation and related technical effects of this solution can be referred to the subsequent method embodiments and will not be elaborated here.

[0107] In a possible implementation, the positioning management function network element 302 sends a second request message to the access network device 301, and the access network device 301 receives the second request message from the positioning management function network element 302. The second request message is used to request the access network device to perform positioning measurements, and the measurement request message carries second information. The second information is used to indicate the terminal device corresponding to the positioning measurement, and the positioning measurement is the positioning measurement performed by the access network device on the positioning signal sent by the terminal device. For the specific implementation and related technical effects of this solution, reference can be made to the subsequent method embodiments, which will not be elaborated here.

[0108] In a possible implementation, the access network device in the embodiments of the present application can cover N cells (for example, cell 1, cell 2, and cell 3). For example, the access network device may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in an LTE system or an enhanced LTE (LTE-advanced, LTE-A) system, such as a traditional macro eNB and a micro eNB in a heterogeneous network scenario. Or, the access network device may include a next generation node B (gNB) in an NR system. Or, the access network device may include a transmission reception point (TRP), a home base station (for example, home evolved NodeB, or homeNode B, HNB), a base band unit (BBU), a BBU pool, or a wireless fidelity (WiFi) access point (AP), etc. Or, the access network device may include a base station in a non-terrestrial network (NTN), that is, it can be deployed on a flying platform or a satellite. In the NTN, the access network device or the access device can act as a layer 1 (L1) relay, or can act as a base station, or can act as an integrated access and backhual (IAB) node. Or, the access network device may be a device that implements the base station function in IoT, such as a device that implements the base station function in drone communication, V2X, D2D, or machine to machine (M2M).

[0109] In some possible scenarios, the access network device in the embodiments of the present application may also be a module or unit capable of implementing some functions of a base station. For example, the access network device may be a central unit (CU), a distributed unit (DU), a CU - control plane (CP), a CU - user plane (UP), or a radio unit (RU), etc. The CU and the DU may be separately provided, or may also be included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio device or a radio unit, such as included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0110] In different systems, the CU (or CU - CP and CU - UP), the DU, or the RU may also have different names, but those skilled in the art can understand their meanings. For example, the access network device may be an access network device or a module of an access network device in an open radio access network (ORAN) system. In the ORAN system, the CU may also be called an open (O) - CU, the DU may also be called an O - DU, the CU - CP may also be called an O - CU - CP, the CU - UP may also be called an O - CU - UP, and the RU may also be called an O - RU. Any one of the CU (or CU - CP, CU - UP), the DU, and the RU in the present application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0111] Optionally, the base station in the embodiments of the present application may include various forms of base stations, such as: macro base stations, micro base stations (also called small stations), relay stations, access points, home base stations, TRPs, transmitting points (TPs), mobile switching centers, etc. The embodiments of the present application do not make specific limitations thereto.

[0112] In a possible implementation manner, the positioning management function network element 302 is an LMF. The LMF refers to a device deployed in the core network to provide positioning functions for a communication network. As Figure 3 shown, the access network device 301 may communicate with the LMF through the access and mobility management function network element 303.

[0113] In a possible implementation, the access and mobility management function network element 303 is the AMF. The AMF refers to a device deployed in the core network that meets the 5G standard and can provide access and mobility management functions for the communication network. The AMF is mainly used to perform registration, connection, reachability, and mobility management, and is used to provide a message transmission channel for the access network device 301 and the positioning management function network element 302. In view of this, the AMF can serve as an access point between the access network device 301 and the core network.

[0114] Optionally, as Figure 3 shown, the above communication system 300 may further include a terminal device 304.

[0115] In a possible implementation, the terminal device in the embodiments of the present application may be, for example, a UE, an access terminal, a terminal unit, a terminal station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a wireless communication device, a terminal agent, or a terminal device in a 5G network or a future evolved public land mobile network (PLMN). The access terminal may be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing devices connected to a wireless modem, an in-vehicle device or a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. In a possible implementation, the terminal device may be mobile or fixed.

[0116] In a possible implementation, the access network device and the positioning management function network element in the embodiments of the present application may also be referred to as communication devices, which may be a general device or a dedicated device, and the embodiments of the present application do not make specific limitations thereto.

[0117] In a possible implementation, the relevant functions of the access network device or the positioning management function network element in the embodiment of the present application can be implemented by one device, or by multiple devices together, or by one or more functional modules in one device, and the embodiment of the present application does not specifically limit this. It can be understood that the above functions can be network elements in hardware devices, or software functions running on dedicated hardware, or a combination of hardware and software, or virtualization functions instantiated on a platform (e.g., a cloud platform).

[0118] For example, the relevant functions of the access network device or the positioning management function network element in the embodiment of the present application can be Figure 4 The communication device 400 is used to implement the above. Figure 4 FIG. 4 is a schematic diagram of the structure of a communication device 400 provided in an embodiment of the present application. The communication device 400 includes one or more processors 401, a communication line 402, and at least one communication interface ( Figure 4 The example in which the communication interface 404 and a processor 401 are used for illustration only) may also include a memory 403.

[0119] The processor 401 may be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application.

[0120] The communication line 402 may include a path for connecting different components.

[0121] The communication interface 404 may be a transceiver module for communicating with other devices or communication networks, such as Ethernet, RAN, wireless local area networks (WLAN), etc. For example, the transceiver module may be a device such as a transceiver or a transceiver. In a possible implementation, the communication interface 404 may also be a transceiver circuit located in the processor 401 to implement signal input and signal output of the processor.

[0122] The memory 403 can be a device with storage function. For example, it can be a read-only memory (ROM), or other types of static storage devices that can store static information and instructions, a random access memory (RAM), or other types of dynamic storage devices that can store information and instructions. It can also be an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM), or other optical disc storage, optical disc storage (including compact discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), magnetic disk storage media, or other magnetic storage devices, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but not limited to this. The memory can exist independently and be connected to the processor through the communication line 402. The memory can also be integrated with the processor.

[0123] Among them, the memory 403 is used to store the computer execution instructions for executing the solution of this application, and is controlled by the processor 401 for execution. The processor 401 is used to execute the computer execution instructions stored in the memory 403, so as to implement the information transmission method provided in the embodiments of this application.

[0124] Alternatively, in the embodiments of this application, it can also be that the processor 401 executes the functions related to the processing of the information transmission method provided in the following embodiments of this application, and the communication interface 404 is responsible for communicating with other devices or communication networks. The embodiments of this application do not make specific limitations on this.

[0125] In a possible implementation manner, the memory 403 in the embodiments of this application can also be used to store the information or parameters described in the following embodiments, such as the first indication information.

[0126] The computer execution instructions in the embodiments of this application can also be referred to as application code, and the embodiments of this application do not make specific limitations on this.

[0128] In a specific implementation, as an embodiment, the communication device 400 can include multiple processors, such as Figure 4The processors 401 and 407 therein. Each of these processors can be a single-CPU processor or a multi-CPU processor. The processors herein can refer to one or more devices, circuits, and / or processing cores for processing data (such as computer program instructions).

[0129] In a specific implementation, as an embodiment, the communication device 400 may further include an output device 405 and an input device 406. The output device 405 communicates with the processor 401 and can display information in various ways.

[0130] The above-mentioned communication device 400 can be a general-purpose device or a dedicated device. For example, the communication device 400 can be a desktop computer, a laptop, a network server, an embedded device, or a device with a Figure 4 similar structure therein. The embodiments of the present application do not limit the type of the communication device 400.

[0131] Next, in combination with Figure 5 , the information transmission method provided by the embodiments of the present application will be further described.

[0132] It should be noted that in the following embodiments of the present application, the message names between each network element, the names of each parameter, or the names of each piece of information, etc. are only examples, and in other embodiments, they can also be other names. The method provided by the embodiments of the present application does not make specific limitations on this.

[0133] It can be understood that in the embodiments of the present application, each network element can execute some or all of the steps in the embodiments of the present application. These steps or operations are only examples, and the embodiments of the present application can also execute other operations or various deformations of the operations. In addition, each step can be executed in a different order presented in the embodiments of the present application, and it is possible not to execute all the operations in the embodiments of the present application.

[0134] Figure 5 is an example of the information transmission method provided by the embodiments of the present application. This method is described by taking the interaction between an access network device and a positioning management function network element as an example. Of course, the entity that executes the actions of the access network device in this method can also be a device / module in the access network device, such as a chip, a processor, a processing unit, etc. in the access network device. The entity that executes the actions of the positioning management function network element in this method can also be a device / module in the positioning management function network element, such as a chip, a processor, a processing unit, etc. in the positioning management function network element. The embodiments of the present application do not make specific limitations on this. Exemplarily, as Figure 5 shown, the information transmission method includes the following steps:

[0135] S501. The positioning management function network element sends a first request message to the access network device. Correspondingly, the access network device receives the first request message from the positioning management function network element.

[0136] Among them, the first request message carries first information. The first information is used to identify the positioning measurement corresponding to the terminal device. The positioning measurement corresponding to the terminal device is the positioning measurement performed by the access network device on the positioning signal sent by the terminal device.

[0137] Optionally, the positioning management function network element and the access network device can communicate through the access and mobility management function network element. In this case, the above S501 can be replaced with: The positioning management function network element sends a first request message to the access and mobility management function network element. Correspondingly, the access and mobility management function network element receives the first request message sent by the positioning management function network element. The access and mobility management function network element sends a first request message to the access network device. Correspondingly, the access network device receives the first request message from the access and mobility management function network element.

[0138] In one example, the positioning signal is SRS. Of course, the above is only an exemplary description of the positioning signal. The above positioning signal can also be other positioning signals. For example, the positioning reference signal (PRS). This application does not make any restrictions on this.

[0139] In one possible implementation, the above first request message is the positioning information request message described in S101. Further, the access network device can add the first information on the basis of the positioning information request message described in S101.

[0140] In one possible implementation, the first information includes an identifier of the positioning measurement corresponding to the terminal device.

[0141] Optionally, the identifier of the positioning measurement corresponding to the terminal device can be the same as the LMF measurement identity (Identity document, ID) (LMF measurement ID) in the measurement request message sent by the positioning management function network element (for example, the measurement request message described in S104). Of course, the above is only an exemplary description of the identifier of the positioning measurement corresponding to the terminal device. The identifier of the positioning measurement corresponding to the terminal device can also be other identifiers. This application embodiment does not make any restrictions on this.

[0142] Exemplarily, Table 1 below gives an example of a positioning information request message. As shown in Table 1 below, the positioning information request message may include a message type, an NRPPA transaction ID, an LMF measurement ID, requested SRS transmission characteristics, UE reporting information, a UE terminal equipment tunnel group (TEG) information request, and a UE TEG reporting periodicity. Among them, the LMF measurement ID may be the identifier of the positioning measurement corresponding to the terminal device described in the embodiments of the present application.

[0143] In addition, the presence, range, IE type and reference, semantics description, criticality, and assigned criticality of each piece of information included in the positioning information request message can be understood with reference to Table 1, which will not be elaborated here.

[0144] Table 1

[0145]

[0146] Of course, the above is only an exemplary description of the positioning information request message. The positioning information request message may also be other information, and the embodiments of the present application do not impose any restrictions on this.

[0147] It can be understood that since the above request message is used to request the configuration information of the positioning signal sent by the terminal device, the above request message is a message related to the terminal device. And the first piece of information can be carried in the request message, that is to say, the first piece of information is also information related to the terminal device. Therefore, in this case, if the first piece of information includes the identifier of the positioning measurement corresponding to the terminal device, the access network device can know that the positioning measurement is the positioning measurement corresponding to the terminal device after receiving the request message.

[0148] As can be seen from the foregoing introduction to the "positioning measurement update process", when the SRS configuration information of the UE changes, the access network device needs to report the changed SRS configuration information of the UE again. The LMF determines a measurement update message based on the changed SRS configuration information of the UE and sends the measurement update message to the access network device. The access network device can only obtain the measurement update message from the LMF side to continue performing positioning measurements on the positioning signals sent by the terminal device according to the measurement update message. That is to say, before S202, even if the SRS configuration information of the UE changes, the access network device will still perform positioning measurements on the positioning signals before the change, which can easily lead to problems such as interruption of positioning measurements or inaccurate positioning measurement results. In view of this, optionally, the information transmission method described in the embodiments of the present application may further include the following step S502.

[0149] S502. When the positioning signal sent by the terminal device changes, the access network device performs positioning measurements corresponding to the terminal device on the changed positioning signal sent by the terminal device.

[0150] It can be understood that the change of the positioning signal sent by the terminal device can also be understood as the change of the positioning signal configuration information of the terminal device.

[0151] In a possible implementation manner, the implementation process of the above S502 may be: when the positioning signal changes, the access network device can update the measurement information required for the access network device to perform positioning measurements corresponding to the terminal device based on the actual situation of the positioning signal change (for example, the time-frequency domain resources required for the access network device to perform positioning measurements corresponding to the terminal device), and perform positioning measurements corresponding to the terminal device on the changed positioning signal sent by the terminal device according to the determined measurement information.

[0152] Exemplarily, as Figure 6 shown, assume that the terminal device 1 switches from cell 1 to cell 2: the access network device needs to reconfigure the configuration information for positioning measurements for the terminal device 1 resident in cell 2, so that the terminal device 1 will send a new positioning signal based on the new SRS configuration information, that is to say, the positioning signal sent by the terminal device 1 will change. As Figure 6 shown in (a) of, if based on the existing positioning update process, before the access network device receives the measurement update message, it will still measure the positioning signal sent by the terminal device before the change and report the measurement result of the positioning signal sent by the terminal device before the change to the positioning management function network element through the access and mobility management function network element. And as Figure 6As shown in (b) of [description], the access network device provided in the embodiment of the present application can directly perform positioning measurements corresponding to the terminal device on the changed positioning signal sent by the terminal device (for example, the positioning signal sent by terminal device 1 staying in cell 2). In addition, the access network device can report the measurement results of the changed positioning signal sent by the terminal device to the positioning management function network element through the access and mobility management function network element.

[0153] It can be understood that when the positioning signal sent by the terminal device changes, the access network device can directly perform positioning measurements corresponding to the terminal device on the changed positioning signal sent by the terminal device, rather than performing positioning measurements corresponding to the terminal device on the positioning signal sent by the terminal device before the change. This not only eliminates the operation of transmitting measurement update messages between the access network device and the positioning management function network element, but also avoids the influence of invalid positioning signals on the positioning measurement results, thereby ensuring the accuracy of the positioning measurement results obtained by the access network device.

[0154] Optionally, after S501, the access network device can also send a positioning information response message (for example, the positioning information response message described in S103) to the positioning management function network element. Correspondingly, the positioning management function network element receives the positioning information response message from the access network device. The positioning information response message includes the positioning signal configuration information of the terminal device.

[0155] Optionally, after S501, the information transmission method provided in the embodiment of the present application further includes: the positioning management function network element sends a second request message to the access network device. Correspondingly, the access network device can receive the second request message from the positioning management function network element. The second request message is used to request the access network device to perform positioning measurements corresponding to the terminal device, and the second request message carries first information.

[0156] It can be understood that the second request message also carries first information, so that the access network device can associate the first request message and the second request message through the first information. If one request message changes, the access network device can determine the other request message according to the association relationship between the first request message and the second request message, and make an adaptive modification to the other request message, so that the changes of the first request message and the second request message can be synchronized, thereby avoiding confusion during the positioning measurement process of the access network device.

[0157] In a possible implementation, the second request message is a measurement request message (for example, the measurement request message described in S104). However, since the measurement request message is a message exchanged in the SRS measurement process, in the case where the second request message is a measurement request message, it can be indicated that the information transmission method described in the embodiments of the present application can also be applied to the scenario of SRS measurement.

[0158] Optionally, after the positioning management function network element sends the second request message to the access network device, the access network device may further send a measurement response message (for example, the measurement response message described in S105) to the positioning management function network element. Correspondingly, the positioning management function network element receives the measurement response message from the access network device. The measurement response message includes the positioning measurement result of the terminal device.

[0159] The present application provides an information transmission method. The access network device can obtain the positioning measurement corresponding to the terminal device through the first information carried in the first request message. Since there is a corresponding relationship between the terminal device and the positioning measurement, the access network device can directly perform positioning measurement on the positioning signal sent by the terminal device. If the positioning signal of the terminal device changes subsequently, the access network device can also directly continue to perform positioning measurement on the signal sent by the terminal device according to the corresponding relationship between the terminal device and the positioning measurement, eliminating the operation of transmitting a measurement update message between the access network device and the positioning management function network element, so that the access network device can perform the positioning measurement corresponding to the terminal device in a timely manner, thereby avoiding delaying the positioning measurement of the terminal device by the access network device.

[0160] Figure 7 This is another example of the information transmission method provided by the embodiments of the present application. This method is described by taking the interaction between the access network device and the positioning management function network element as an example. Of course, the entity that executes the actions of the access network device in this method can also be a device / module in the access network device, such as a chip, a processor, a processing unit, etc. in the access network device. The entity that executes the actions of the positioning management function network element in this method can also be a device / module in the positioning management function network element, such as a chip, a processor, a processing unit, etc. in the positioning management function network element. The embodiments of the present application do not make specific limitations in this regard. Exemplarily, as Figure 7 shown, the information transmission method includes the following steps:

[0161] S701. The positioning management function network element sends a second request message to the access network device. Correspondingly, the access network device receives the second request message from the positioning management function network element.

[0162] Among them, the second request message is used to request the access network device to perform positioning measurement. The measurement request message carries second information. The second information is used to indicate the terminal device corresponding to the positioning measurement. The positioning measurement is the positioning measurement performed by the access network device on the positioning signal sent by the terminal device.

[0163] Optionally, the positioning management function network element and the access network device may communicate through the access and mobility management function network element. In this case, the above S701 may be replaced with: The positioning management function network element sends a second request message to the access and mobility management function network element. Correspondingly, the access and mobility management function network element receives the second request message sent by the positioning management function network element. The access and mobility management function network element sends a second request message to the access network device. Correspondingly, the access network device receives the second request message sent by the access and mobility management function network element.

[0164] In a possible implementation manner, the above second request message may be a measurement request message, that is, the measurement request message recorded in S104. And the fact that the second request message carries second information can be understood as adding second information on the basis of the measurement request message recorded in S104.

[0165] In a possible implementation manner, the second information includes the identifier or associated identifier of the terminal device.

[0166] It can be understood that since the above second request message is used to request the access network device to perform positioning measurement, the above second request message is a message related to positioning measurement. And the second information can be carried in the measurement request message. That is to say, the second information is also information related to positioning measurement. Therefore, in this case, when the second information includes the identifier or associated identifier of the terminal device, the access network device can know that the positioning measurement corresponds to the terminal device after receiving the measurement request message.

[0167] Optionally, the identifier of the terminal device may be identifier information used to indirectly identify the terminal device, or information used to directly indicate the identifier of the terminal device. The embodiments of the present application do not impose any restrictions on this. The associated identifier may be used to associate the terminal device with the positioning measurement, that is, to associate the first request message and the second request message.

[0168] In the embodiments of the present application, the relevant description of S701 may refer to the above S501 and will not be elaborated here.

[0169] Further, after the access network device receives the second request message from the positioning management function network element, if the positioning signal sent by the terminal device changes, the description of the access network device performing positioning measurement on the changed positioning signal sent by the terminal device can specifically refer to the description of the above embodiments and will not be elaborated here.

[0170] In a possible implementation manner, before the access network device receives the second request message (i.e., S701) from the positioning management function network element, the access network device may further send a positioning information response message to the positioning management function network element. Correspondingly, the positioning management function network element receives the positioning information response message from the access network device. The positioning information response message is used to indicate the positioning signal configuration information of the terminal device and carries the second information.

[0171] That is to say, the access network device can inform the positioning management function network element of the second information in advance so that the subsequent positioning management function network element can carry the second information in the measurement request message. In addition, since the positioning information response message is a message exchanged in the SRS measurement process, when the second information is carried in the positioning information response message, it can indicate that the information transmission method described in the embodiments of the present application can also be applied to the SRS measurement scenario.

[0172] Exemplarily, the above positioning information response message may be the positioning information response message described in S103.

[0173] Optionally, before the access network device sends the positioning information response message to the positioning management function network element, the positioning management function network element may further send a positioning information request message (for example, the positioning information request message described in S101) to the access network device. Correspondingly, the access network device receives the positioning information request message from the positioning management function network element. The positioning information request message is used to request the positioning signal configuration information of the terminal device.

[0174] Optionally, after the access network device receives the second request message (i.e., S701) from the positioning management function network element, the access network device may further send a measurement response message (for example, the measurement response message described in S105) to the positioning management function network element. Correspondingly, the positioning management function network element receives the measurement response message from the access network device. The measurement response message includes the positioning measurement result of the terminal device.

[0175] The present application provides an information transmission method. The access network device can learn about the terminal device corresponding to the positioning measurement through the second information carried in the second request message. Since there is a corresponding relationship between the terminal device and the positioning measurement, the access network device can directly perform positioning measurement on the positioning signal sent by the terminal device. If the positioning signal of the terminal device changes subsequently, the access network device can also directly continue to perform positioning measurement on the signal sent by the terminal device according to the corresponding relationship between the terminal device and the positioning measurement, eliminating the operation of transmitting measurement update messages between the access network device and the positioning management function network element, so that the access network device can perform timely positioning measurement corresponding to the terminal device, thereby avoiding delays in the access network device performing positioning measurement corresponding to the terminal device.
