"And/or" in this article is only an association relationship describing the associated objects, which means that there can be three kinds of relationships. For example, A and/or B can mean: A alone exists, A and B exist at the same time, and B exists alone. These three situations. In addition, "at least one" means one or more, and "plurality" means two or more. The words "first" and "second" do not limit the quantity and order of execution, and the words "first" and "second" do not limit the difference.

It should be noted that in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

The method provided in the embodiments of this application can be applied to long term evolution (LTE) systems, fifth-generation (5th-generation, 5G) systems, new radio (NR) systems, and wireless local area networks. , WLAN) system and future evolution system or a variety of communication integration systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. For ease of description, the method provided in the embodiment of the present application is applied to a 5G system or an NR system as an example to illustrate the method provided in the embodiment of the present application. When the method provided in the embodiment of the present application is applied to other systems, it is only necessary to replace the network element in the embodiment of the present application with a network element with the same or similar functions in the corresponding system.

The access network of the 5G system or the NR system may be referred to as the next generation (NG)-radio access network (RAN). One or more network devices can be included in the NG-RAN. A network device is an entity on the network side that is used to send signals, or receive signals, or send signals and receive signals, and is used to provide wireless communication functions for the terminal. The network equipment included in the NG-RAN may be a next generation node base station (gNB), a next generation evolved NodeB (ng-eNB), and so on.

Among them, the network device can be a complete entity or a separate architecture. Under the separated architecture, the network equipment includes a centralized unit (CU) and a distributed unit (DU). CU realizes part of the functions of network equipment, and DU realizes part of the functions of network equipment. For example, the CU is responsible for processing non-real-time protocols and services, and implements radio resource control (radio resource control, RRC) and packet data convergence protocol (packet data convergence protocol, PDCP) layer functions. The DU is responsible for processing physical layer protocols and real-time services, and realizes the functions of radio link control (RLC), media access control (MAC) and physical (physical, PHY) layers. Further, the CU may also be in a form in which the user plane (UP) (referred to as CU-UP in this article) and the control plane (CP) (referred to as CU-CP in this article) are separated.

In a 5G system or NR system, the traditional positioning architecture can be seen in Figure 1. The network equipment involved in terminal positioning in NG-RAN includes gNB and ng-eNB. LMF and AMF are located in the core network. AMF is the interface between network equipment and core network, including access management and mobility management-related functions, and is mainly responsible for forwarding the positioning-related messages between the terminal and the LMF and the network equipment and the LMF. LMF is used to receive the positioning request from the AMF, determine the method used for positioning measurement (the decision can be based on the capabilities of the terminal and the network, or based on the information contained in the positioning request, etc.), determine the network device to locate the terminal and report it to the network The device or terminal requests auxiliary information required for positioning, sends the auxiliary information required for positioning to the terminal or network device, requests measurement information from the terminal or network device, calculates the position of the terminal, and so on. The interfaces between the various network elements can be seen in Figure 1, which will not be repeated here.

Based on the positioning architecture shown in Figure 1, according to the originator of the positioning service, there are currently three types of positioning:

Mobile terminal location request (MT-LR): The location service comes from a location service entity in the core network (for example, a gateway mobile location center (GMLC)). The location service entity can specify A certain terminal performs positioning. Specifically, the location service entity may send a location service request (hereinafter referred to as the location request) to the AMF. After the AMF receives the location request, it sends the location request to the LMF. After receiving the location request, the LMF initiates and executes the location measurement process , Obtain positioning measurement information through the positioning measurement process, calculate the position of the terminal according to the positioning measurement information, and send the position information of the terminal to the AMF, and then the AMF to the positioning service entity.

Network-induced location request (NI-LR): The location service comes from AMF, that is, the operator's network initiates the location itself. Specifically, if the AMF needs the location information of the terminal, it sends a location request to the LMF. After receiving the location request, the LMF initiates and executes the location measurement process, obtains the location measurement information through the location measurement process, calculates the location of the terminal based on the location measurement information, and Send the location information of the terminal to the AMF.

Mobile originated location request (MO-LR): The location service comes from the terminal itself. The terminal sends a location request to the AMF, and the AMF obtains the location information of the terminal from the LMF (the specific process is similar to the specific implementation process of MT-LR, and will not be repeated here), and sends the location information of the terminal to the terminal.

In order to locate the terminal more quickly, as shown in Figure 2, the LMC can be deployed in the network equipment. In this case, the network device can directly send a positioning request to the deployed LMC, which is different from the positioning request received by the LMF in the traditional positioning architecture from the AMF. The location type of the location request sent by the network device may be referred to as a radio access network initiated location request (RAN induced location request, RI-LR). For ease of description, in the solutions shown in Figures 6 to 13 in the following embodiments of this application, the method provided by this application is described by taking the network device sending a location request to the LMC as an example. In actual implementation, the network device can also send a location request to the AMF or LMF sends a positioning request.

In the embodiment of this application, LMC can be deployed in NG-RAN, and there are three possible ways of deploying LMC on NG-RAN:

Method 1: In the case that the network device is a complete entity, the LMC is deployed on the network device and belongs to the functional module of the network device. Refer to Figure 2 for details.

Method 2: In the case of a separate architecture of the network equipment, the LMC is deployed on the network equipment, and the LMC is an independent logical network element and has logic with the CU (or CU-CP of the network equipment) of the network equipment where it is located interface. As shown in Fig. 3, in Fig. 3, a logical interface between the LMC and the CU of the network device where it is located is taken as an example for drawing.

Mode 3: The LMC is an independent logical network element and is connected to multiple network devices (or CU of the network device or CU-CP of the network device). Refer to Figure 4. In Figure 4, the LMC is connected to multiple network devices as an example for drawing.

It should be noted that the deployment methods of LMC shown in Figures 2 to 4 are only exemplary. In actual implementation, the number of network devices participating in terminal positioning can be greater, and the deployment of LMCs is not limited to those shown in the figure. The position shown, any LMC deployment method, and the method provided in the embodiment of this application can be applicable.

It should be noted that, in the embodiment of the present application, the LMC in the architecture shown in FIG. 2 to FIG. 4 can also support any one of NI-LR, MT-LR, and MO-LR in addition to supporting RI-LR. kind.

When LMC supports NI-LR, MT-LR or MO-LR, AMF does not send a location request to LMF, but sends a location request to LMC. After receiving the location request, LMC initiates and executes the location measurement process, which is obtained through the location measurement process Position measurement information, calculate the position of the terminal according to the position measurement information, and send the position information of the terminal to the AMF.

Currently, there is no solution for how to configure the functions supported by LMC in the description for RI-LR. In addition, the core network LMF does not support network devices directly initiating positioning to it. Therefore, there is no solution for how to initiate positioning for network devices that have not deployed LMC.

In order to clarify which positioning functions the LMC has, this application provides a positioning method, as shown in Figure 5, including:

501. The LMC sends a registration request to a core network element. Among them, the registration request is used to request registration to the core network element. Correspondingly, the core network element receives the registration request from the LMC.

Optionally, the core network element is AMF or LMF.

Among them, in each embodiment of the present application, the registration request may also be referred to as an LMC registration (LMC registration) message.

502. The core network element sends a registration response to the LMC. Correspondingly, the LMC receives a registration response from the core network element.

Wherein, the registration response includes first indication information, the first indication information is used to indicate the positioning type supported by the LMC; or, the first indication information is used to indicate whether the LMC supports the first positioning type.

Among them, when the core network element is the LMF, the LMF and the LMC can exchange information through the AMF.

Among them, in each embodiment of the present application, the registration response may also be referred to as an LMC registration confirmation (LMC registration ACK) message.

Optionally, the positioning types supported by the LMC include one or more of the following positioning types: NI-LR, MT-LR, MO-LR, RI-LR.

The first indication information may directly indicate the positioning type supported by the LMC. For example, the first indication information may be a list, and the list includes information about the positioning type supported by the LMC.

The first indication information may also be multiple bits, and the value of the multiple bits is used to indicate which positioning types the terminal supports. For example, multiple bits can be 2 bits. When the value of 2 bits is 00, it means that LMC supports NI-LR and MT-LR. When the value of 2 bits is 10, it means that LMC supports MT-LR and MO. -LR, when the value of 2 bits is 01, it means that LMC supports MO-LR and RI-LR, and when the value of 2 bits is 11, it means that LMC supports NI-LR and RI-LR. For another example, the multiple bits are 4 bits, each of the 4 bits corresponds to a positioning type, and the value of 1 bit is used to indicate whether the LMC supports the corresponding positioning type. Exemplarily, if the first bit corresponds to NI-LR, the second bit corresponds to MT-LR, the third bit corresponds to MO-LR, and the fourth bit corresponds to RI-LR. Assuming that the value of 1 bit is 1, it means that the LMC supports the corresponding positioning type. Then, when the value of 4 bits is 0001, it means that LMC supports RI-LR, but does not support NI-LR, MT-LR, and MO-LR. When the value of 4 bits is 1110, it means that LMC supports NI-LR, MT-LR and MO-LR, but does not support RI-LR.

Optionally, the first positioning type includes any one of the following positioning types: NI-LR, MT-LR, MO-LR, RI-LR.

For each positioning type, 1 bit can be used to indicate whether the LMC supports the positioning type. For example, the first indication information can indicate whether RI-LR is supported by 1 bit. When the value of this bit is 0, it means that LMC does not support RI-LR. When the value of this bit is 1, it means that LMC supports RI-LR. . The reverse is also possible.

In the method provided by the embodiment shown in FIG. 5, during the LMC registration process, the core network element can indicate the positioning type supported by the LMC, so that the subsequent LMC can perform the corresponding positioning function. In addition, LMF does not support the new positioning type RI-LR, while LMC supports RI-LR. By authorizing the RI-LR positioning type for the LMC, the function of the LMC can be within the jurisdiction of the core network.

In order to solve the problem of initiating positioning by network devices that have not deployed LMC, this application also provides a positioning method. The positioning method can be implemented in several ways. In the implementation manner 1, a network device that supports a certain positioning type (denoted as the second positioning type) can use the second positioning type for positioning of all terminals served. In the implementation manner 2, the network device to which the cell supporting the second positioning type belongs can use the second positioning type to locate all terminals in the cell. In the implementation manner 3, a network device that supports access of a terminal of the second positioning type can use the second positioning type to locate the terminal. The following describes the implementation process of these three implementation methods in detail.

Implementation manner 1: A network device that supports the second positioning type can use the second positioning type for positioning of all terminals served.

In implementation 1, the LMC or the core network element can instruct the network device to support the second positioning type. The following uses scenario 1.1 (LMC indicates that the network device supports the second positioning type) and scenario 1.2 (the core network element indicates that the network device supports the second positioning type). Two positioning types) respectively describe the positioning methods provided in this application.

Scenario 1.1. The LMC indicates that the network device supports the second positioning type.

In scenario 1.1, referring to Figure 6, the positioning method includes:

601. The LMC sends a registration request to the core network element. Among them, the registration request is used to request registration to the core network element. Correspondingly, the core network element receives the registration request from the LMC.

Optionally, the core network element is AMF or LMF.

602. The core network element sends a registration response to the LMC. Wherein, the registration response includes information about M1 network devices that support the second positioning type, and M1 is an integer greater than 0. Correspondingly, the LMC receives a registration response from the core network element.

Among them, when the core network element is the LMF, the LMF and the LMC can exchange information through the AMF. The information of the network device may be the identity of the network device or the information of the cell of the network device (for example, the cell identity), and the like.

Optionally, the second positioning type is RI-LR.

It should be noted that the information of the M1 network devices can also be sent to the LMC through other messages exchanged between the core network element and the LMC, for example, the message after the registration is completed (for example, the existing NG interface application layer protocol (NG) The application protocol (NGAP) message or the newly defined NGAP message) is not limited to registration requests and registration responses. In order to facilitate understanding, the registration request and registration response are used as examples.

603. The LMC sends second indication information corresponding to each network device to each of the M1 network devices, where the second indication information is used to indicate that the corresponding network device supports the second positioning type. Correspondingly, the M1 network devices receive the second indication information from the LMC.

Exemplarily, if M1=2 and the M1 network devices are network device 1 and network device 2, the second indication information sent by LMC to network device 1 is used to indicate that network device 1 supports the second positioning type, and LMC sends network device 1 and network device 2 respectively. The second indication information sent by the device 2 is used to indicate that the network device 2 supports the second positioning type.

Among them, in each embodiment of the present application, the second indication information may be carried in an existing message (for example, an existing Xn interface application protocol (Xn application protocol, XnAP) message) or a new message (for example, LMC service indication (LMC service indication) message). Optionally, in each embodiment of the present application, the network device may also reply with a response to an existing message or a new message, where the response to the new message may be called LMC service indication ACK (LMC service indication ACK) information. The third indication information, the fourth indication information, the fifth indication information, the sixth indication information, and the seventh indication information in the following are similar to the second indication information, and will not be repeated hereafter. It should be noted that the LMC service indication message and the LMC service indication confirmation message are only examples of the name of the new message, and may also be other names, which are not limited in this application.

604. When any one of the M1 network devices needs to locate the served terminal, the network device sends a location request to the LMC.

Optionally, referring to FIG. 6, before step 604, the method further includes:

603A. The LMC sends the location information of the LMC to each of the M1 network devices. Correspondingly, M1 network devices receive the location information of the LMC from the LMC.

Optionally, the location information of the LMC is the identity of the network device where the LMC is located (at this time, the LMC is deployed in the network device) or the identity of the LMC (at this time, the LMC can be deployed in the network device or outside the network device ).

The second indication information and the location information of the LMC may be carried in the same message or in different messages, which is not limited in this application.

Among them, after receiving the location information of the LMC, the network device can determine which device to send the location request to when it needs to locate the terminal to be served. It should be noted that the location information of the LMC may not be sent by the LMC to the network device, but may be pre-configured in each network device, which is not limited in this application.

Optionally, referring to FIG. 6, after step 602, the method further includes:

605. The core network element sends update information to the LMC. Wherein, the update information is used to indicate whether to support relevant information of M2 network devices whose information of the second positioning type has changed, and M2 is an integer greater than 0. Correspondingly, the LMC receives update information from the core network element.

In the various embodiments of the present application, the update information may be carried in an existing message or a new message (for example, an LMC function update message). Similar to the LMC service indication message and the LMC service indication confirmation message, the LMC function update message is only an example of the name of the new message, and may also be other names, which is not limited in this application.

In the first case, the updated information is the updated information of the network device supporting the second positioning type (for example, the identification of the network device). In this case, by comparing the network devices that support the second positioning type before and after the update, LMC can determine which network devices have changed from supporting the second positioning type to not supporting the second positioning type, and which network devices have never supported the second positioning type. The type has changed to support the second positioning type.

Exemplarily, referring to Table 1, if the network equipment supporting the second positioning type before the update includes network equipment 1 and network equipment 2, and the network equipment supporting the second positioning type includes network equipment 1 and network equipment 3 after the update, the LMC can It is determined that the network device 2 has changed from supporting the second positioning type to not supporting the second positioning type, and the network device 3 has never supported the second positioning type but has changed to supporting the second positioning type.

Table 1

更新前支持第二定位类型的网络设备Network equipment supporting the second positioning type before the update	更新后支持第二定位类型的网络设备Network devices that support the second positioning type after the update
网络设备1Network equipment 1	网络设备1Network equipment 1
网络设备2Network equipment 2	网络设备3Network equipment 3

In the second case, the update information is the information of the M2 network devices that support the second positioning type information (for example, the identification of the network device), and the LMC will update the information according to the network devices that support the second positioning type before the update. Determine which network devices have changed from supporting the second positioning type to not supporting the second positioning type, and which network devices have changed from not supporting the second positioning type to supporting the second positioning type.

Exemplarily, refer to Table 2. If the network devices that support the second positioning type before the update include network device 1 and network device 2, the M2 network devices that support the change in the information of the second positioning type are network device 1 and network device 3. , The LMC can determine that the network device 2 has changed from supporting the second positioning type to not supporting the second positioning type, and that the network device 3 has never supported the second positioning type but has changed to supporting the second positioning type.

Table 2
