[0049] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0050] The terms "first", "second", etc. of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited, for example, the first object can be one or more. In addition, "or" in the present application represents at least one of the connected objects. For example, "A or B" covers three schemes, namely, Scheme 1: including A but not including B; Scheme 2: including B but not including A; Scheme 3: including both A and B. The character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0051] The term "indication" in this application can be a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, operations to be performed, or request results in the sent indication; an indirect indication can be understood as the receiver determining the corresponding information according to the indication sent by the sender, or making a judgment and determining the operation to be performed or the request result according to the judgment result.

[0052] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following descriptions, but these technologies can also be applied to systems other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0053] In order to facilitate understanding of the embodiments of the present application, the following technical points are first introduced:

[0054] 1. Introduction to NWDAF.

[0055] NWDAF is a network data analysis function network element that supports the collection of network element or terminal related data and provides information such as statistics and forecasts. NWDAF can collect data from network elements such as AMF, Session Management Function (SMF) or Operations, Administration and Maintenance (OAM). In the existing process, NWDAF obtains the location information of the terminal through AMF. The terminal location information is coarse-grained, at the Tracking Area (TA) or cell level, that is, NWDAF can know from AMF which cell or TA the terminal is currently in.

[0056] If an NWDAF consumer initiates a service request to NWDAF and requests NWDAF to collect relevant statistics or make predictions, NWDAF will collect information from different network elements according to the parameters in the request message. After NWDAF performs statistics and analysis, it returns the results to the NWDAF consumer.

[0057] 2. Introduction to Location Service (LCS).

[0058] The location service is implemented and provided by network elements such as AMF and LMF in the core network. LCS messages are exchanged between the terminal and the LCS client or application function (AF). A typical process is the mobile terminated location request (MT-LR).

[0059] The MT-LR process is initiated by an external third-party application (eg, LCS client) or by the AF via the Network Exposure Function (NEF) network element, and finally obtains the terminal's location information via network elements such as GMLC, AMF, and LMF.

[0263] In an embodiment of the present application, the first communication device can obtain the positioning-related data corresponding to the third communication device from the second communication device by request or subscription, so that the network side can obtain the positioning-related data, and then the network side can use the positioning-related data for model training and other operations.

[0264] The implementation of the present application is introduced below in combination with Example 1 and Example 2.

[0265] Embodiment 1:

[0266] See also Figure 5 , the specific steps are as follows:

[0267] Step 500: NWDAF obtains a UE identifier (UE ID) or a group ID.

[0268] NWDAF can first obtain certain area information, and then convert the area information into UE identification, group ID and other information; wherein UE ID is the identification of the UE in the area, and group ID is the identification of the group to which the UE in the area belongs;

[0269] Optionally, the UE identifier includes but is not limited to at least one of GPSI and SUPI.

[0270] Optionally, the group ID includes but is not limited to an internal group identifier (Internal Group Identifier) ​​or an external group identifier (External Group Identifier).

[0271] In one implementation, the NWDAF requests information such as a UEID or group ID corresponding to a certain area information by requesting a network element such as an AMF;

[0272] In another implementation, the NWDAF may also be based on its internal logic or other means to obtain information such as UEID or group ID, such as carried when a network element, as a consumer of a certain analytics task, requests an analytics task.

[0273] It should be noted that the execution of this step or subsequent steps may be due to the internal logic of NWDAF, or requests from other network elements, such as when a consumer requests an analysis task. At this time, NWDAF does not have a model corresponding to the analysis task, so it needs to collect data for model training.

[0274] Step 501: NWDAF sends first information to GMLC, where the first information is used to request to obtain positioning related data.

[0275] Specifically, the NWDAF may send first information to the GMLC through services such as Ngmlc_Location_ProvideLocation, where the first information is used to request the acquisition of positioning-related data.

[0276] The positioning-related data may include data corresponding to the third communication device.

[0277] Optionally, the positioning-related data may include data generated by a seventh communication device.

[0278] Step 502: GMLC sends the sixth information to AMF, where the sixth information is used to request the acquisition of positioning-related data, etc.

[0279] Specifically, GMLC sends sixth information to AMF through Namf_Location_ProvidePositioningInfo based on the first information received in step 501. Optionally, the sixth information may include at least part of the content of the first information. Further, the content of the sixth information may be set according to the content of the first information. For example, the sixth information may also include at least one of the following: (1) client type, used to indicate the type of communication device initiating the request, such as the network function (NF) network element type; (2) required LCS service quality (QoS), used to indicate the conditions that must be met for LCS service, such as the accuracy that must be met, such as the accuracy of the positioning result (Accuracy), including horizontal accuracy (Horizontal Accuracy), vertical accuracy (VerticalAccuracy), etc.; delay that must be met, such as no delay, low delay, etc.

[0280] It should be noted that, in step 502, the GMLC can verify the privacy information of the UE according to the UE ID or group ID in the first information to determine whether the relevant data of the target UE can be reported.

[0281] Step 503: The AMF selects an LMF according to the sixth information, and sends the seventh information to the selected LMF, where the seventh information is used to request to obtain positioning-related data, etc.;

[0282] Specifically, the AMF may select the LMF according to information such as the area where the UE is located. After selecting the target LMF, the seventh information is sent to the target LMF, and the seventh information may be sent through services such as Nlmf_Location_DetermineLocation. Among them, the content of the seventh information may include at least part of the content of the sixth information, and the content of the seventh information may be further set according to the content of the sixth information. For example, the seventh information sent by the AMF to the LMF carries the location service association identifier (LCScorrelation ID), and deletes information such as the UE ID;

[0283] Optionally, the seventh information may include at least one of the following information:

[0284] (1) third information (or target data type);

[0285] (2) fourth information (or information of the target device);

[0286] (3) Fifth information (or target collection method);

[0287] (4) filtering information of positioning-related data, used to indicate the conditions that the positioning-related data must meet;

[0288] (5) Notification Target Address.

[0289] (6) tenth information, where the tenth information is used to indicate that the type of the message carrying the first information is a request message;

[0290] (7) eleventh information, where the eleventh information is used to indicate that the type of the message carrying the first information is a subscription message;

[0291] (8) Subscription related identification;

[0292] (9) One or more terminal identifiers (UE IDs);

[0293] (10) Group ID;

[0294] (11) Identification information of the third communication device.

[0295] Step 504: LMF interacts with the seventh communication device to obtain positioning related data;

[0296] Specifically, the LMF can interact with the seventh communication device, such as positioning, and obtain positioning-related data during the interaction. For example, during the positioning process, the LMF obtains measurement data of the seventh communication device, or obtains location information and other data of the seventh communication device; or before positioning, the LMF interacts with the seventh communication device to obtain some auxiliary data, etc.;

[0297] Optionally, the seventh communication device may include at least one of RAN, UE, PRU, and LMF.

[0298] It should be noted that step 504 may be performed before the LMF receives the seventh information, or may be performed after the seventh information and before the LMF sends the second information. According to the information carried in the seventh information (such as the second information, the sixth information or the ninth information, etc.), the LMF may determine the number of interactions or the interaction time with the seventh communication device (such as RAN, UE, PRU, etc.). For example, LMF can store positioning-related data locally, and after receiving the seventh information, report the positioning-related data when it is determined that the current local / historical positioning-related data meets the indication of the information carried in the seventh information; for example, when the data collection method is non-actively triggered data collection, or the filtering information of the positioning-related data includes time information of the past time (such as the time of the past week, etc.), LMF can select the positioning-related data corresponding to the third communication device based on the historical data / locally stored data; or there is no or cannot be local positioning-related data stored, LMF can immediately perform interaction according to the content of the seventh information after receiving the seventh information to obtain the positioning-related data corresponding to the third communication device and report it, or LMF triggers the positioning and other interactive operations in other ways and reports the collected positioning-related data corresponding to the third communication device, or regularly interacts and reports the positioning-related data corresponding to the third communication device, or reports after accumulating a certain amount of positioning-related data corresponding to the third communication device, etc. For example, when the data collection method is actively triggered data collection, or the filtering information of the positioning-related data includes time information of the future time, LMF can immediately perform one or more positioning and other interactions, and report the collected positioning-related data;

[0299] It should be noted that the historical data in this application have the same meaning as historically generated data, local data, locally stored data, etc. and can be replaced with each other.

[0300] Optionally, the interaction may refer to a positioning operation, or other operations that can obtain positioning-related data;

[0301] Step 505-7: LMF sends the second information to AMF, AMF sends the eighth information to GMLC, GMLC sends the ninth information to NWDAF, etc., wherein the eighth information and the ninth information may include at least part of the content of the second information. Further, the content of the eighth information can be set according to the content of the second information, and the content of the ninth information can be set according to the content of the second information or the eighth information.

[0302] Specifically, LMF collects the positioning-related data corresponding to the third communication device based on the seventh information, and feeds back the positioning-related data that meets the conditions, such as sending the positioning-related data to AMF through the Nlmf_location_determineLocation Response service message, or directly sending it to GMLC (if there is a GMLC address); or when sending it to AMF, AMF can send it to GMLC through the Namf_Location_ProvidePositioningInfo Response service message; GMLC feeds back to NWDAF through Ngmlc_Location_ProvideLocation Response, etc.

[0303] The positioning related data includes: numerical information of the positioning related data, which may refer to information such as numbers represented by the positioning related data;

[0304] Optionally, the positioning-related data also includes at least one of the following:

[0305] (1) Data name;

[0306] (2) Data type;

[0307] For example, it may be positioning measurement data, location information accuracy, location information, intermediate feature data, positioning assistance data, etc.; or it may be a specific data type, such as RSRP, PDP, CIR, etc.; or it may be a combination of the two, such as positioning measurement data, CIR, etc.; Global Navigation Satellite System (GNSS) data, etc.;

[0308] (3) Time information;

[0309] Time information refers to the time corresponding to the positioning related data that needs to be fed back, such as the time when the positioning related data is generated, or the time when the positioning related data is collected;

[0310] (4) Data source information;

[0311] Optionally, the data source information is used to indicate that the positioning-related data is generated by the PRU; or, the data source information is used to indicate that the positioning-related data is generated by the UE or LMF; or, the data source information is used to indicate that the positioning-related data is generated by the RAN node.

[0312] Optionally, step 508: LMF sends second information to NWDAF.

[0313] Step 508 and steps 505 to 507 are two different ways of LMF feeding back positioning related data. After step 504, step 505-7 may be performed, or step 508 may also be performed.

[0314] Embodiment 2:

[0315] See also Figure 6 , the specific steps are as follows:

[0316] Step 600: NWDAF obtains UE ID or group ID.

[0317] Step 601: NWDAF initiates a first message to GMLC, where the first message is used to request subscription to positioning related data.

[0318] Specifically, the NWDAF may send first information to the GMLC through services such as Ngmlc_Location_ProvideLocation, where the first information is used to request the acquisition of positioning-related data.

[0319] The positioning-related data may include data corresponding to the third communication device.

[0320] Step 602: GMLC sends sixth information to AMF, where the sixth information is used to request subscription to positioning related data, etc. Optionally, the sixth information may include at least part of the content of the first information, and further, the content of the sixth information may be set according to the content of the first information.

[0321] Step 603: AMF selects LMF according to the sixth information, and sends seventh information to the selected LMF, where the seventh information is used to request subscription to positioning-related data, etc.; wherein the sixth information and the seventh information contain at least part of the content carried by the first information. Optionally, the content of the seventh information can be set according to the content of the first information or the sixth information.

[0322] Step 604: The LMF interacts with the seventh communication device to obtain positioning related data;

[0323] Optionally, the seventh communication device may include at least one of RAN, UE, PRU, and LMF.

[0324] Step 605-7: LMF sends the second information to AMF, AMF sends the eighth information to GMLC, GMLC sends the ninth information to NWDAF, etc., wherein the eighth information and the ninth information may include at least part of the content of the second information. Further, the content of the eighth information may be set according to the content of the second information, and the content of the ninth information may be set according to the content of the second information or the eighth information.

[0325] Optionally, step 608: LMF sends second information to NWDAF.

[0326] Step 608 and steps 605 to 607 are two different ways of LMF feeding back positioning related data. After step 604, step 605-7 may be performed, or step 608 may also be performed.

[0327] The difference between Example 2 and Example 1 is that in Example 2, the first information sent by NWDAF is a subscription message. Therefore, in step 601-3, the first information, the sixth information and the seventh information need to carry the parameters required for subscribing to the positioning-related data; the reporting conditions of the positioning-related data in step 604 are also different from those in step 504, and the positioning-related data can be reported after the interaction; the message carrying the positioning-related data in step 605-7 is also different from the message carrying the positioning-related data in step 505-7, for example, it is not a response message corresponding to the request message, but a message corresponding to the subscription message, such as a notification message.
