[0266] 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.

[0267] The following describes the implementation of the present application in conjunction with Example 1 and Example 2.

[0268] Example 1:

[0269] Referring to Figure 5, the specific steps are as follows:

[0270] Step 500: NWDAF obtains UE identifier (UE ID) or group ID.

[0271] NWDAF can first obtain a 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;

[0272] Optionally, the UE identifier includes but is not limited to at least one of GPSI and SUPI.

[0273] 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).

[0274] In one embodiment, the NWDAF requests information such as the UE ID or group ID corresponding to a certain area information by requesting a network element such as the AMF;

[0275] In another embodiment, the NWDAF may also obtain information such as the UE ID or group ID based on its internal logic or other means, such as information carried when a network element, as a consumer of a certain analytics task, requests an analytics task.

[0276] 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 a consumer requesting 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.

[0277] Step 501: NWDAF sends first information to GMLC, where the first information is used to request acquisition of positioning-related data.

[0278] 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 acquisition of positioning-related data.

[0279] The positioning-related data may include data corresponding to the third communication device.

[0280] Optionally, the positioning-related data may include data generated by a seventh communication device.

[0281] Step 502: GMLC sends sixth information to AMF, where the sixth information is used to request positioning-related data, etc.

[0282] Specifically, the GMLC sends the sixth information to the 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 that initiates 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 (Vertical Accuracy), etc.; the delay that must be met, such as no delay, low delay, etc.

[0283] It should be noted that, in step 502, the GMLC may 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.

[0284] Step 503: The AMF selects an LMF based on the sixth information and sends a seventh information to the selected LMF, where the seventh information is used to request positioning-related data, etc.

[0285] Specifically, the AMF may select an LMF based on information such as the area where the UE is located. After selecting the target LMF, the AMF may send seventh information to the target LMF. The seventh information may be sent through services such as Nlmf_Location_DetermineLocation. The content of the seventh information may include at least part of the content of the sixth information. The content of the seventh information may be further set based on the content of the sixth information. For example, the seventh information sent by the AMF to the LMF may carry a location service correlation identifier (LCS correlation ID) and delete information such as the UE ID.

[0286] Optionally, the seventh information may include at least one of the following information:

[0287] (1) third information (or target data type);

[0288] (2) fourth information (or information of the target device);

[0289] (3) Fifth information (or target collection method);

[0290] (4) Filtering information for positioning-related data, used to indicate the conditions that the positioning-related data must meet;

[0291] (5) Notification Target Address.

[0292] (6) tenth information, the tenth information being used to indicate that the type of the message carrying the first information is a request message;

[0293] (7) eleventh information, the eleventh information being used to indicate that the type of the message carrying the first information is a subscription message;

[0294] (8) Subscription related identification;

[0295] (9) One or more terminal identifiers (UE IDs);

[0296] (10) Group ID;

[0297] (11) Identification information of the third communication device.

[0298] Step 504: The LMF interacts with the seventh communication device to obtain positioning-related data;

[0299] Specifically, the LMF may interact with the seventh communication device, such as for 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 data such as location information of the seventh communication device; or the LMF interacts with the seventh communication device before positioning to obtain some auxiliary data, etc.

[0300] Optionally, the seventh communication device may include at least one of RAN, UE, PRU, and LMF.

[0301] It should be noted that step 504 may be performed before the LMF receives the seventh information, or after the seventh information and before the LMF sends the second information. Based on the information carried in the seventh information (such as the second information, the sixth information, or the ninth information), 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, the LMF may store positioning-related data locally, and after receiving the seventh information, report the positioning-related data if it determines that the current local / historical positioning-related data meets the requirements indicated by the information carried in the seventh information. For example, when the data collection method is non-actively triggered data collection, or when the filtering information of the positioning-related data includes time information of the past time (e.g., time of the past week, etc.), the LMF may select the positioning-related data corresponding to the third communication device based on the historical data / locally stored data. Alternatively, if there is no or no positioning-related data stored locally, the LMF may immediately perform an interaction based on the content of the seventh information after receiving the seventh information to obtain and report the positioning-related data corresponding to the third communication device. Alternatively, the LMF may report the collected positioning-related data corresponding to the third communication device after triggering an interaction operation such as positioning in other ways, or may periodically interact and report the positioning-related data corresponding to the third communication device, or may report the positioning-related data corresponding to the third communication device after accumulating a certain amount of positioning-related data corresponding to the third communication device. For example, when the data collection method is actively triggered data collection, or when the filtering information of the positioning-related data includes time information of a future time, the LMF may immediately perform one or more positioning interactions and report the collected positioning-related data.

[0302] 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 used interchangeably.

[0303] Optionally, the interaction may refer to a positioning operation, or other operations that can obtain positioning-related data;

[0304] 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., where the eighth information and the ninth information may include at least part of the content of the second information. Furthermore, 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.

[0305] 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.

[0306] 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;

[0307] Optionally, the positioning-related data also includes at least one of the following:

[0308] (1) Data name;

[0309] (2) Data type;

[0310] For example, it can be positioning measurement data, location information accuracy, location information, intermediate feature data, positioning assistance data, etc.; or it can be a specific data type, such as RSRP, PDP, CIR, etc.; or it can be a combination of the two, such as positioning measurement data, CIR, etc.; Global Navigation Satellite System (GNSS) data, etc.;

[0311] (3) Time information;

[0312] 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;

[0313] (4) Data source information;

[0314] 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.

[0315] Optionally, step 508: LMF sends second information to NWDAF.

[0316] Step 508 and steps 505 to 507 are two different ways for LMF to feedback positioning related data. After step 504, step 505-7 can be performed, or step 508 can also be performed.

[0317] Example 2:

[0318] Referring to Figure 6, the specific steps are as follows:

[0319] Step 600: NWDAF obtains UE ID or group ID.

[0320] Step 601: NWDAF sends a first message to GMLC, where the first message is used to request subscription to positioning-related data.

[0321] 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 acquisition of positioning-related data.

[0322] The positioning-related data may include data corresponding to the third communication device.

[0323] Step 602: The GMLC sends sixth information to the 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. Furthermore, the content of the sixth information may be set according to the content of the first information.

[0324] Step 603: The AMF selects an LMF based on the sixth information and sends a seventh message to the selected LMF. The seventh message is used to request a subscription to positioning-related data, etc. The sixth and seventh messages contain at least part of the content carried by the first message. Optionally, the content of the seventh message can be set based on the content of the first or sixth message.

[0325] Step 604: The LMF interacts with the seventh communication device to obtain positioning-related data;

[0326] Optionally, the seventh communication device may include at least one of RAN, UE, PRU, and LMF.

[0327] 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., where the eighth information and the ninth information may include at least part of the content of the second information. Furthermore, 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.

[0328] Optionally, step 608: LMF sends second information to NWDAF.

[0329] Step 608 and steps 605 to 607 are two different ways for LMF to feedback positioning related data. After step 604, step 605-7 can be performed, or step 608 can also be performed.

[0330] The difference between Example 2 and Example 1 is that in Example 2, the first message sent by the NWDAF is a subscription message. Therefore, in step 601-3, the first, sixth, and seventh messages must carry the parameters required for subscribing to positioning-related data. The reporting conditions for positioning-related data in step 604 are also different from those in step 504, and positioning-related data can be reported after interaction. The message carrying positioning-related data in step 605-7 is also different from the message carrying positioning-related data in step 505-7. For example, it is not a response message corresponding to a request message, but a message corresponding to a subscription message, such as a notification message.
