[0092] The following first describes the related technologies of the embodiments of the present application.

[0093] 1. Network Data Analytics Function (NWDAF)

[0094] This functional network element 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, SMF, or Operation Administration and Maintenance (OAM). In the current 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.

[0095] If an NWDAF consumer initiates a service request to NWDAF, requesting NWDAF to collect relevant statistics or make predictions, then 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.

[0096] 2. Location Service (LCS)

[0097] It is executed and provided by network elements such as AMF and LMF in the core network. LCS messages are exchanged between user equipment (UE) and LCS client or application function (AF). A typical process is the mobile terminated location request (MT-LR).

[0098] The MT-LR process is initiated by an external third-party application (LCS client) or by the AF via the NEF network element, and finally obtains the UE's location information through the Gateway Mobile Location Centre (GMLC), AMF, LMF and other network elements.

[0099] The channel between NWDAF and LMF via GMLC, AMF and then LMF can only be used to request and obtain location information, lacking data types such as measurement data; and can only obtain data based on UE ID or group ID, which is inefficient. As a result, NWDAF cannot efficiently obtain sufficient data from LMF.

[0100] 3. In the prior art, LMF does not register its support for AI positioning-related or data collection-related information, and NWDAF or other network elements cannot quickly find a suitable LMF to perform subsequent AI positioning-related operations, such as data collection, AI positioning, etc.

[0101] The information transmission method, apparatus and communication device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0102] like Figure 2 As shown, the embodiment of the present application provides an information transmission method, including:

[0103] Step 201: A first network element sends first information to a second network element, where the first information is used to request to obtain positioning-related data of a target area;

[0104] Step 202: The first network element receives second information from a third network element, where the second information includes positioning-related data of the target area.

[0105] It should be noted that the positioning-related data of the target area can be understood as the positioning-related data related to the terminal in the target area generated or acquired, or the positioning-related data of the target area can also be understood as the positioning-related data related to the terminal in the target area generated or acquired by the access network node in the target area;

[0106] Optionally, the terminals within the target area may refer to all terminals or any terminal (anyUE) within the target area.

[0107] It should be noted that the embodiment of the present application obtains the positioning-related data of the target area from the third network element by sending the first information for requesting the acquisition of the positioning-related data of the target area to the second network element, so as to directly obtain the positioning-related data of the specific area and improve the data acquisition efficiency.

[0108] It should be noted that the above positioning-related data may be at least one, or at least one item. Positioning-related data may be understood as positioning-related data, and positioning-related data may include data generated by different communication devices such as UE / LMF / radio access network (RAN) node / positioning reference unit (PRU), and positioning-related data may be at least one of the following: measurement data, position data, intermediate feature data, or auxiliary data, etc.

[0109] It should be noted that positioning-related data can also be distinguished according to positioning methods, such as data in uplink positioning and data in downlink positioning. The above-mentioned data in uplink positioning and data in downlink positioning can refer to data generated during the uplink positioning or downlink positioning process, and can also be measurement data, position data, intermediate feature data or auxiliary data in uplink positioning or downlink positioning.

[0110] Optionally, in an implementation manner, the first information includes at least one of the following:

[0111] A11, area information corresponding to the target area;

[0112] It should be noted that the area information is used to indicate an area range. Optionally, for example, it can be area information based on longitude and latitude. The area information / area range based on longitude and latitude can be in the form of a geographic area description (GAD) shape, such as including the shape of a geographic area (such as a rectangle) and the longitude and latitude description of the shape (such as the longitude and latitude information of the four corners of the rectangle); optionally, for example, it can also be cell-based area information (which can be indicated by cell information (such as cell ID), tracking area (TA) identifier, TA list, etc.), that is, the area range is represented by at least one cell, and the cell coverage range is the corresponding area range.

[0113] It should be noted that the area information may be area information indicating an area of ​​interest, that is, area information that the first network element is interested in and wants to collect data about. It can be understood that the area information is used to indicate that the first network element wants to collect positioning-related data for the area indicated by the area information.

[0114] In one implementation, the area information corresponding to the target area may indicate that data is collected based on the area information.

[0115] A12, first indication information, wherein the first indication information is used to indicate passive data collection;

[0116] It should be noted that the first indication information specifically indicates that the third network element does not need to trigger additional interactions to realize data collection. For example, after receiving the first information, the third network element does not trigger additional interactions due to the first information, such as positioning operations / positioning interactions, but interacts based on trigger conditions in the prior art (such as positioning interactions), and then collects positioning-related data generated during the interaction. The positioning interaction process can occur at a historical time, a current time, or a future time, determined based on data limiting information;

[0117] Optionally, passive data collection may also be referred to as non-active data collection, passive collection, or data collection in a non-actively triggered positioning manner, etc.

[0118] It should be noted that the indication can be an explicit indication or an implicit indication.

[0218] It should be noted that, when the search request message includes information indicating the AI ​​positioning method that the communication device to be searched needs to support, the fifth network element can search for a communication device that supports the AI ​​positioning method (for example, a third network element that supports the AI ​​positioning method) according to the “information indicating the AI ​​positioning method that the communication device to be searched needs to support”. For example, if the search request message indicates that the search supports uplink positioning, the fifth network element searches for a third network element that supports uplink positioning.

[0219] It should be noted that the AI ​​positioning method can be understood as an AI positioning type, or a positioning mode. The AI ​​positioning method may refer to, for example, uplink positioning, downlink positioning, PRS-based positioning, SRS-based positioning, AI / ML-based uplink positioning, AI / ML-based downlink positioning, AI / ML-based and PRS-based positioning, or AI / ML-based and SRS-based positioning. It should be noted that the positioning mode may also directly correspond to Case 1, Case 2a, Case 2b, Case 3a, Case 3b, etc. in the existing discussion.

[0220] Specifically, the following five situations are defined in the existing standards:

[0221] - Case 1: UE positioning, the model is at the UE end, including direct AI / ML positioning or AI / ML assisted positioning;

[0222] - Case 2a: UE-assisted positioning / LMF positioning, the model is on the UE side, AI / ML-assisted positioning;

[0226] The uplink positioning method can be understood as a method for acquiring positioning information based on measurement data reported from the RAN as input data for inference, such as the RAN (base station) performs measurements based on signals sent by the terminal and reports the measurement data. The downlink positioning method can be understood as a method for acquiring positioning information based on measurement data reported from the UE as input data for inference, such as the UE performs measurements based on signals sent by the RAN and reports the measurement data.

[0227] When the search request message includes information indicating the AI ​​positioning reasoning method that the communication device to be searched needs to support, the fifth network element can search for a communication device that supports the AI ​​positioning reasoning method (for example, a third network element that supports the AI ​​positioning reasoning method) based on the "information indicating the AI ​​positioning reasoning method that the communication device to be searched needs to support".

[0228] When the search request message includes information indicating the type or granularity of input data that the communication device being searched needs to support, the fifth network element can search for a communication device that supports the type or granularity of input data (for example, a third network element that supports the type or granularity of input data) based on the "information indicating the type or granularity of input data that the communication device being searched needs to support".

[0231] When the search request message includes information about the second network element, the fifth network element (e.g., NRF) makes a judgment based on the information about the second network element and the information about the device supported by the third network element requesting AI positioning analysis, thereby determining that the second network element can interact with the third network element and send an AI positioning request.

[0232] In the case where the search request message includes information about the positioning object, the information about the positioning object is used to instruct the fifth network element to search for a third network element that allows AI positioning of the positioning object. For example, the information about the positioning object indicates that the positioning object is a UE, and the communication device (network element) searched by the fifth network element (e.g., NRF) is a communication device that allows AI positioning of the UE (e.g., a third network element that allows AI positioning of the UE).

[0233] In the case where the search request message includes information indicating the time when the communication device to be searched needs to support AI positioning, the fifth network element can search for a communication device that supports AI positioning at that time (e.g., a third network element that supports AI positioning at that time) based on the “information indicating the time when the communication device to be searched needs to support AI positioning”. It should be noted that the time can be a period of time.

[0234] When the search request message includes information indicating an area where the communication device to be searched needs to support AI positioning, the fifth network element can search for a communication device that supports AI positioning in the area (for example, a third network element that supports AI positioning in the area) based on the "information indicating an area where the communication device to be searched needs to support AI positioning".

[0235] In one implementation, the information indicating the need for model training capabilities corresponding to the AI ​​positioning model can be understood as information indicating the need for model training capabilities corresponding to AI positioning, or information indicating that the communication device requesting the search needs to have model training capabilities corresponding to AI positioning.

[0236] In the case where the search request message includes information indicating that the communication device to be searched needs to have the model training capability corresponding to the AI ​​positioning model, the fifth network element can search for a communication device with the model training capability corresponding to the AI ​​positioning model (e.g., a third network element with the model training capability corresponding to the AI ​​positioning model) based on the “information indicating that the communication device to be searched needs to have the model training capability corresponding to the AI ​​positioning model”. It should be noted that “having the model training capability corresponding to the AI ​​positioning model” can be understood as supporting the model training corresponding to the AI ​​positioning model.

[0237] In one implementation, the information indicating the need for model training capabilities corresponding to the AI ​​positioning model can be understood as information indicating the need for model reasoning capabilities corresponding to AI positioning, or information indicating that the communication device requesting the search needs to have model reasoning capabilities corresponding to AI positioning.

[0238] In the case where the search request message includes information indicating that the communication device to be searched needs to have the model reasoning capability corresponding to the AI ​​positioning model, the fifth network element can search for a communication device with the model reasoning capability corresponding to the AI ​​positioning model (e.g., a third network element with the model reasoning capability corresponding to the AI ​​positioning model) based on the “information indicating that the communication device to be searched needs to have the model reasoning capability corresponding to the AI ​​positioning model”. It should be noted that “having the model reasoning capability corresponding to the AI ​​positioning model” can be understood as supporting the model reasoning corresponding to the AI ​​positioning model.

[0239] In one implementation, the information indicating the need for model acquisition capability corresponding to the AI ​​positioning model can be understood as information indicating the need for model acquisition capability corresponding to AI positioning, or information indicating that the communication device requesting the search needs to have model acquisition capability corresponding to AI positioning.

[0240] In the case where the search request message includes information indicating that the communication device to be searched needs to have the model acquisition capability corresponding to the AI ​​positioning model, the fifth network element can search for a communication device with the model acquisition capability corresponding to the AI ​​positioning model (e.g., a third network element with the model acquisition capability corresponding to the AI ​​positioning model) based on the “information indicating that the communication device to be searched needs to have the model acquisition capability corresponding to the AI ​​positioning model”. It should be noted that “having the model acquisition capability corresponding to the AI ​​positioning model” can be understood as supporting the model acquisition corresponding to the AI ​​positioning model.

The fifth network element can search for a communication device with model training capability, model reasoning capability, and / or model acquisition capability based on the information (for example, a third network element with model training capability, model reasoning capability, and model acquisition capability).

[0242] It should be noted that AI positioning refers to the ability to introduce AI in the positioning process. For example, communication equipment such as UE / RAN / LMF uses AI / machine learning (ML) models to process measurement data and / or intermediate feature data and / or auxiliary information to obtain intermediate feature data or positioning result data (eg location information, etc.). This process can be regarded as an inference process related to AI positioning. Similarly, AI positioning can also refer to model training related to AI positioning.

[0243] Optionally, the fifth network element mentioned in the embodiment of the present application refers to a network element or communication device capable of storing and discovering network element information, for example, the fifth network element may be an NRF.

[0244] For example, the second network element determines that it needs to obtain positioning-related data within an area range based on longitude and latitude granularity. The second network element needs to first determine which third network element services are needed for the area range based on longitude and latitude granularity. At this time, the second network element needs to request a third network element from the fifth network element based on the area range with longitude and latitude granularity. Based on the request of the second network element, the fifth network element searches for a third network element that meets the conditions among the locally registered third network elements and feeds back to the second network element. The second network element can directly use the feedback from the fifth network element, or further determine which third network elements specifically receive the message from the feedback from the fifth network element.

[0245] Optionally, in order for the fifth network element to know which third network elements exist, each third network element needs to register with the fifth network element when accessing the network.

[0251] C102, capability information supporting AI positioning;

[0252] The capability information is used to indicate the capability of the third network element to support AI positioning. If the registration request message does not include the information, it means that the third network element does not support the capability of AI positioning.

[0261] It should be noted that the ability to support training data collection can be used to indicate that the network element being registered has the ability to collect data for training models. It can be understood that the third network element being registered indicates that it has the ability to collect data and / or that the collected data is used for model training through the "ability to support training data collection". It should be noted that in the present application, the "ability to support training data collection" in the registration process (such as a registration request message) is used to indicate that the registered network element has the ability to collect data for training models, and the "ability to support training data collection" in the network element search process (such as a network element discovery message) is used to indicate that the network element to be searched must have the ability to collect data for training models.

[0262] C105. Time range supported for data collection; it should be noted that this time range is used to indicate the time range supported by the network element for registration for data collection. For example, if the indicated time is historical time (i.e., the time period or time point before the search request message is sent), it means that the third network element to be searched needs to have the ability to retain historical data.

[0263] C106, AI positioning related capability information

[0264] It should be noted that the capability information related to AI positioning includes at least one of the following:

[0265] The AI ​​positioning method supported by the third network element;

[0266] The AI ​​positioning reasoning method supported by the third network element;

[0267] The type or granularity of input data supported by the third network element;

[0268] The type or granularity of output data supported by the third network element;

[0269] The positioning accuracy supported by the third network element is used to indicate at least one of the precision and credibility of the positioning analysis result;

[0270] Allowing the third network element to be requested for information about a device that performs AI positioning analysis;

[0271] Information about the object of positioning that allows the use of AI positioning;

[0274] Information indicating whether the third network element has a model training capability corresponding to the AI ​​positioning model;

[0275] Information indicating whether the third network element has a model reasoning capability corresponding to the AI ​​positioning model;

[0276] Information indicating whether the third network element has the model acquisition capability corresponding to the AI ​​positioning model. Among them, the AI ​​positioning method supported by the third network element can be understood as the AI ​​positioning type supported by the third network element, or can also be understood as the positioning mode supported and used by the third network element. In one embodiment, the AI ​​positioning method supported by the third network element may refer to, for example, uplink positioning, downlink positioning, PRS-based positioning, SRS-based positioning, AI / ML-based uplink positioning, AI / ML-based downlink positioning, AI / ML-based and PRS-based positioning, or AI / ML-based and SRS-based positioning, etc. It should be noted that the positioning mode can also directly correspond to Case 1, Case 2a, Case 2b, Case 3a, Case 3b, etc. in the existing discussion.

[0277] Specifically, the following five situations are defined in the existing standards:

[0278] - Case 1: UE positioning, the model is at the UE end, including direct AI / ML positioning or AI / ML assisted positioning;

[0279] - Case 2a: UE-assisted positioning / LMF positioning, the model is on the UE side, AI / ML-assisted positioning;

[0280] -Case 2b: UE-assisted positioning / LMF positioning, the model is on the LMF side, direct AI / ML positioning;

[0281] - Case 3a: NG-RAN assisted positioning, model on the gNB side, AI / ML assisted positioning;

[0282] - Case 3b: NG-RAN assisted positioning, model on the LMF side, direct AI / ML positioning.

[0283] The uplink positioning method can be understood as a method for acquiring positioning information based on measurement data reported from the RAN as input data for inference, such as the RAN (base station) performs measurements based on signals sent by the terminal and reports the measurement data. The downlink positioning method can be understood as a method for acquiring positioning information based on measurement data reported from the UE as input data for inference, such as the UE performs measurements based on signals sent by the RAN and reports the measurement data.

[0284] Among them, the AI ​​positioning reasoning methods supported by the third network element may include but are not limited to direct positioning, indirect positioning, etc. It should be noted that direct positioning may refer to directly outputting positioning analysis results (location information) based on measurement data and AI / ML models, etc.; it can be understood that the direct positioning is that the reasoning output data is the positioning result information. Indirect positioning may refer to outputting intermediate features based on measurement data and AI / ML models, and the intermediate features can be used to determine the positioning analysis results (location information), etc. It can be understood that the indirect positioning is that the reasoning output data is the positioning intermediate information.

[0285] Among them, the types of input data supported by the third network element may include but are not limited to at least one of the following: measurement data, intermediate characteristic data and auxiliary data. The measurement data may be but are not limited to Channel Impulse Response (CIR), power delay profile (PDP), delay profile (DP), reference signal received power (RSRP), reference signal received path power (RSRPP) or reference signal time difference (RSTD), PRS, SRS, etc. The intermediate characteristic data may be but are not limited to Time of Arrival (TOA), or path phase, etc. The auxiliary data may be but are not limited to Reference Signal Configuration (RS configuration), etc.

[0286] The granularity of the input data supported by the third network element may be a tracking area (TA) granularity, a cell granularity or other finer granularity, wherein the finer granularity may be smaller than the granularity of the cell granularity.

[0287] In an optional implementation manner, the registration request message may include the type or granularity of input data required by the third network element.

[0288] The output data may be, but is not limited to, positioning analysis information, etc. Based on this, the types of output data supported by the third network element may include at least one of the following: positioning result information and positioning intermediate information (or intermediate features).

[0289] The granularity of the output data supported by the third network element may be, but is not limited to, positioning analysis information at a TA granularity, positioning analysis information at a cell granularity, or positioning analysis information at a finer granularity.

[0290] The positioning accuracy supported by the third network element is used to indicate at least one of the precision and credibility of the positioning analysis result. In one embodiment, the positioning accuracy supported by the third network element is used to indicate at least one of the precision and credibility of the positioning analysis information (positioning analysis result) obtained by inference. For example, the positioning accuracy supported by the third network element can be 98% credibility, and the positioning error is less than 0.5 meters.

[0291] The information of the device that is allowed to request the third network element to perform AI positioning analysis is used to indicate which devices can request the third network element to perform AI positioning analysis. The information of the device may include at least one of the following: the type of device, the manufacturer information of the device, the device identification, and the address information of the device. The type of the device may be UE, Positioning Reference Unit (PRU), gNB, or LMF, etc.

[0292] Among them, the information of the positioning objects that allow AI positioning is used to indicate that the third network element allows AI positioning for those positioning objects. It can be understood that the positioning object is the object to be positioned, for example, if the UE is positioned, the positioning object is the UE. Among them, the information of the positioning object may include at least one of the following: the type of the positioning object, the manufacturer information of the positioning object, the identification of the positioning object, and the address information of the positioning object. Among them, the type of the positioning object may be UE, Positioning Reference Unit (PRU), gNB or LMF, etc.

[0293] The information about the time when the third network element supports AI positioning is used to indicate the times when the third network element supports AI positioning. For example, the information about the time when the third network element supports AI positioning is 8:00, which means 18:00.

[0294] The information of the area in which the third network element supports AI positioning is used to indicate in which areas the third network element supports AI positioning. Wherein, the area refers to the area under the jurisdiction of the third network element. In one embodiment, the information of the area in which the third network element supports AI positioning is used to indicate in which areas under its jurisdiction the third network element supports AI positioning.

[0295] In one implementation, the information indicating whether the third network element has the model training capability corresponding to the AI ​​positioning model can be understood as information indicating whether the third network element has the model training capability corresponding to the AI ​​positioning; the model training capability corresponding to the AI ​​positioning (model) refers to the training capability of the AI / ML model used for positioning, or the ability to train AI / ML models related to positioning.

[0296] The information indicating whether the third network element has the model reasoning capability corresponding to the AI ​​positioning model can be understood as information indicating whether the third network element has the model reasoning capability corresponding to the AI ​​positioning model; the model reasoning capability corresponding to the AI ​​positioning (model) refers to the ability to generate output data or reasoning results (such as location information) based on the AI ​​positioning model (AI / ML model).

[0297] The information indicating whether the third network element has the model acquisition capability corresponding to the AI ​​positioning model can be understood as information indicating whether the third network element has the model acquisition capability corresponding to AI positioning. The model acquisition capability corresponding to the AI ​​positioning (model) refers to the ability to interact with other communication devices to obtain an AI positioning module (AI / ML model). For example, if the third network element can interact with communication devices such as NWDAF, MTLF, ADRF, etc. that have model training capabilities or model storage capabilities, thereby obtaining AI / ML models related to AI positioning, then the third network element has the model acquisition capability corresponding to the AI ​​positioning (model).

[0298] In one implementation, the above-mentioned AI / ML model can be used for AI positioning.

[0299] In one implementation, whether the third network element supports AI positioning can be indirectly indicated by indicating whether the third network element has the model training capability corresponding to the AI ​​positioning model, whether it has the model reasoning capability corresponding to the AI ​​positioning model, or whether it has the model acquisition capability corresponding to the AI ​​positioning model.

[0300] In one implementation, the AI ​​positioning-related capability information includes information indicating whether the third network element has at least one of the following corresponding to the AI ​​positioning model: model training capability, model reasoning capability, and model acquisition capability.

[0301] In an embodiment of the present application, a third network element (e.g., LMF) registers information related to its support for AI positioning or data collection (e.g., sending AI positioning-related capability information through a registration request message), and NWDAF or other network elements quickly find a suitable LMF to perform subsequent AI positioning-related operations, such as data collection, AI positioning, etc.

[0302] In addition, the registration of the third network element can also help the communication device that needs to perform AI positioning to determine the target third network element. In one implementation method, a communication device that needs AI positioning (which may be the second network element or other device mentioned in this application, such as NWDAF, GMLC, AMF, UE and other communication devices) may need to determine the location information through AI positioning. The communication device can send a request message (such as an AI positioning request) to the third network element to request AI positioning or determine the location information, or the communication device sends a request message to the third network element through the second network element. Before the communication device sends a request message to the third network element, it is necessary to first find a third network element that supports AI positioning. After finding a third network element that supports AI positioning, the communication device can send a search request to the fifth network element to find the target third network element with relevant capabilities such as AI positioning.

[0303] Optionally, the registration request message may further include: area information corresponding to the third network element;

[0304] It should be noted that the area information is used to indicate the service range covered by the third network element, and may also be referred to as service area information corresponding to the third network element.

[0305] It should be noted that after receiving the registration request message from the third network element, the fifth network element needs to store the information corresponding to the third network element and feed back a response message to the third network element.

[0306] It should be noted that, since the first information can be used to indicate active data collection or passive data collection, optionally, in one implementation, when the second network element determines that the third network element needs active data collection, in order to facilitate the third network element to perform active data collection, the third information sent by the second network element to the third network element should include the terminal identification information corresponding to the target area, and the terminal here can be understood as the terminal associated with the positioning-related data, for example, the terminal can be UE, PRU, etc. For example, the terminal identification information can be UE ID, user permanent identifier (SUbscription Permanent Identifier, SUPI), International Mobile Equipment Identity (International Mobile Equipment Identity, IMEI), etc., or it may be a processed (AMF does not directly expose UE ID, but maps it to other identifiers) terminal identifier, such as positioning service association identifier (LCS correlation ID), etc.

[0307] After receiving the terminal identification information, the third network element may trigger interaction with the terminal based on the terminal identification information to obtain positioning-related data.

[0308] Optionally, in another implementation method, the second network element may not directly tell the terminal identification information corresponding to the target area, but when the third network element determines that the third network element needs active data collection (the determination method for the third network element that needs active data collection is based on the active data collection determination implicitly or explicitly indicated by the third information), in order to facilitate the third network element to perform active data collection, the third network element directly sends a first request information to the second network element, and the second network element determines the terminal identification information corresponding to the target area based on the first request information; the second network element sends the terminal identification information to the third network element.

[0309] Optionally, the first request information is used to request to obtain terminal identification information corresponding to the target area, or it can also be understood that the first request information is used to request to convert the target area.

[0310] The first request information includes at least one of the following:

[0311] C21, area information corresponding to the target area;

[0312] Optionally, the area information included in the first request information should be a subset or a complete set of area information actually corresponding to the target area.

[0313] C22, fourth indication information, the fourth indication information is used to instruct to obtain the terminal identification information corresponding to the target area;

[0314] It should be noted that, optionally, in the case where the first request information is used to request conversion of the target area, the fourth indication information indicates conversion of the target area into corresponding terminal identification information.

[0315] It should also be noted that when the regional granularity is a cell granularity, the location information of a certain device can be known after the third network element interacts, but the third network element may only obtain geographical location information (or location information based on longitude and latitude), rather than location information at the cell granularity. Therefore, an additional method is required to convert the geographical location information into location information at the cell granularity; optionally, any of the following three methods may be used in the embodiment of the present application:

[0316] Method 1: Enhance the UE. When the UE reports the location information, it also reports the corresponding cell information (e.g., cell ID). It should be noted that the UE reporting the cell information at the same time may be the UE's own capability, that is, the UE itself decides to report the cell ID and other information when performing positioning and other interactions; or the third network element may request the UE to report the geographical location information and the cell-granular location information at the same time when requesting;

[0317] Method 2: The third network element sends a second request message to the second network element, and the second network element determines the cell corresponding to the target area based on the latitude and longitude granularity according to the second request message; the second network element sends the cell information to the third network element.

[0318] Optionally, the second request information is used to request to obtain cell information corresponding to the target area based on longitude and latitude granularity, or it can also be understood that the second request information is used to request to convert the target area.

[0319] Optionally, in an implementation manner, the second request information includes at least one of the following:

[0320] C31, area information corresponding to the target area;

[0321] It should be noted that the area information may also be area information corresponding to positioning-related data collected when the third network element interacts with the device in the target area, such as location data. Alternatively, the area information may also be understood as area information corresponding to positioning-related data, location data corresponding to the target area, etc. That is, after obtaining the location data based on longitude and latitude, the third network element requests the second network element to determine the cell information corresponding to the location data, etc.

[0322] C32. Fifth indication information, wherein the fifth indication information is used to indicate obtaining cell information corresponding to the target area.

[0323] Optionally, when the second request information is used to request conversion of the target area, the fifth indication information is used to instruct conversion of the target area into corresponding cell information.

[0324] Optionally, when the second request information is used to request the conversion of the target area, the second request information should also include:

[0325] Sixth indication information, where the sixth indication information is used to indicate a target granularity after conversion;

[0326] Optionally, the target granularity may be a cell identifier granularity and / or a TA granularity.

[0327] It should be noted that the indication can be an explicit indication or an implicit indication. In the case of an explicit indication, the second request information needs to include the sixth indication information; in the case of an implicit indication, the second request information does not need to include the sixth indication information. For example, it can be indicated by information such as an information name, and the second network element can determine the target granularity after conversion based on the second request information sent by the third network element.

[0328] It should be noted that how the second network element converts the longitude and latitude location information into the cell-granularity location information is not restricted here, and is the internal logic and implementation of the second network element. For example, the cell-granularity location information can be determined by comparing the mapping relationship within the second network element.

[0329] Method three: the second network element carries the area information based on longitude and latitude in the third information at the same time; specifically, after receiving the area information based on cell granularity, the second network element may first convert the area information into the area information based on longitude and latitude, and then send the area information based on longitude and latitude to the third network element; it may also be that after receiving the area information based on cell granularity from the first network element, the fifth network element first converts the area information into the area information based on longitude and latitude, and then sends the area information based on longitude and latitude to the second network element.

[0330] It should be noted that the positioning-related data may include at least one piece of positioning-related data, or multiple pieces of positioning-related data generated by multiple different UEs, or multiple pieces of positioning-related data generated by multiple different devices, etc.

[0331] Optionally, in an implementation manner, the second information further includes at least one of the following:

[0332] D11, data type corresponding to the positioning related data;

[0333] It should be noted that the data type refers to the data type corresponding to at least one piece of positioning related data. It can be understood that the data type can be the data type of positioning related data. The data type can be measurement data, location data, intermediate feature data, auxiliary data, etc.; it can also be a specific data type, such as RSRP, PDP, CIR, etc.; it can also be a combination of the two, such as measurement data, CIR, etc.

[0334] D12, time information corresponding to the positioning related data;

[0335] It should be noted that the time information refers to the time corresponding to the data, such as the time when the data is generated, or the time when the data is collected.

[0336] D13, a data source corresponding to the positioning related data;

[0337] It should be noted that the data source refers to the source of positioning-related data, or can also be understood as the generator of positioning-related data, such as indicating that the generator of positioning-related data is PRU, UE, LMF, RAN, etc. The data source is usually indicated through a device identifier.

[0338] D14, area information corresponding to the positioning related data;

[0339] It should be noted that the region information is used to indicate the region where the data is generated, and may be a region range, such as region information based on longitude and latitude granularity.

[0340] D15, terminal identification information corresponding to the positioning related data;

[0341] It should be noted that this information is used to indicate which terminals the positioning-related data is related to.

[0342] For example, the terminal identification information may include UE ID, SUPI, IMEI, etc.

[0343] D16, access network node identification information corresponding to the positioning related data;

[0344] It should be noted that the information is used to indicate which access network nodes the positioning related data is related to, for example, the information is used to indicate which access network nodes the positioning related data is generated by. The access network node identification information may also be referred to as base station identification information.

[0345] D17. Generation method of the positioning related data

[0346] It should be noted that the generation mode corresponding to the positioning-related data can be used to indicate the positioning method for generating the positioning-related data, or to indicate the positioning process for generating the positioning-related data. It can be understood that the generation mode corresponding to the positioning-related data can indicate in which positioning process the positioning-related data is generated, or in which positioning process corresponding to which positioning method the positioning-related data is generated.

[0347] In one implementation, the generation method corresponding to the positioning related data may be used to include at least one of a positioning type, a measurement method, a measurement type, a positioning measurement method, and a positioning measurement type.

[0348] In one implementation, the generation mode, positioning method or positioning process corresponding to the above-mentioned positioning-related data may refer to at least one of the following: uplink positioning, downlink positioning, PRS-based positioning (positioning based on PRS measurement data), SRS-based positioning (positioning based on SRS measurement data), UE-assisted positioning (such as UE assisted positioning), RAN-assisted positioning (such as NG-RAN node assisted positioning), etc.

[0349] It should be noted that, depending on the type of the third information (request information or subscription information), the conditions of the data reporting method of the third network element are different, and the triggering method of the third network element reporting positioning-related data is also different. For example, when it is a request information, the third network element only feeds back / reports positioning-related data once; when it is a subscription information, the third network element feeds back / reports positioning-related data multiple times within the subscription time period. Optionally, if the reporting condition is periodic reporting, the third network element will report when each period arrives; optionally, if the reporting condition is event-triggered reporting, the third network element will trigger reporting when the event condition is met, for example, based on the amount of data, reporting after collecting a certain amount of data, etc.; or, for example, based on time, such as reporting data at a certain time node (a time node, or a fixed time node, such as next Monday, or every Monday, etc.).

[0350] The specific application examples of the embodiments of the present application are described below.

[0351] Application 1: Regional information based on latitude and longitude granularity, passive data collection

[0352] like Figure 3 As shown in the figure, the specific implementation process includes:

[0353] Step 301: NWDAF sends first information to GMLC to request to obtain positioning related data;

[0354] Optionally, the first information is used to implicitly or explicitly indicate passive data collection.

[0355] Optionally, the positioning-related data may refer to measurement data generated by UE / LMF / RAN, etc.

[0356] Specifically, NWDAF can send first information to GMLC through services such as Ngmlc_Location_ProvideLocation, and the first information is used to request the acquisition of positioning-related data. The positioning-related data may include data generated by different communication devices such as UE / LMF / RAN / PRU, such as measurement data; location data; intermediate features; auxiliary data, etc.

[0357] Step 302: Forward the first information to AMF.

[0358] GMLC sends the first information to AMF to request the acquisition of positioning-related data, etc. For example, GMLC sends the first information to AMF through Namf_Location_ProvidePositioningInfo according to the first information received in step 301, wherein the message sent by GMLC may carry the client type (such as NF network element type), the required LCS service quality (QoS), etc. in addition to the first information (area information; indication information of passive data collection; subscription indication information; subscription indication information; data limitation information, etc.).

[0359] It should also be noted that the first information received by GMLC may not be completely consistent with the content contained in the first information actually forwarded. For example, the subscription address may be sent by GMLC instead of NWDAF (because LMF may still not be able to interact directly with NWDAF).

[0360] Step 303, AMF searches for LMF from NRF;

[0361] For example, the AMF may select a suitable LMF based on local configuration or based on a request message. Specifically, when the AMF selects the LMF based on a request message, the AMF may search for a LMF that meets the conditions through the NRF, and the NRF may feed back the network element information of the LMF that meets the conditions, including the address information of the LMF (IP address, network element identification information, etc.).

[0362] Step 304: The AMF sends the third information to the selected LMF.

[0363] Specifically, after searching for a network element and determining the selected LMF, the AMF sends the third information to the selected LMF network element. The third information may be sent through services such as Nlmf_Location_DetermineLocation.

[0364] Step 305: LMF interacts with devices such as UE / PRU / RAN;

[0365] Specifically, LMF may interact with devices such as UE / RAN / PRU before or after receiving the third information, such as executing a positioning process, to obtain positioning-related data, including historical data or future data. For example, during the positioning interaction, LMF obtains measurement data and / or intermediate feature data of UE / RAN / PRU; or obtains location data of UE / PRU; or before performing positioning, LMF interacts with devices such as RAN to obtain some auxiliary data.

[0366] It should be noted that, optionally, the interaction in this step may occur before the LMF receives the third information or after the LMF receives the third information.

[0367] It should be noted that the triggering of these interactions is similar to the existing technology and is based on the triggering of other devices, such as UE, RAN, other LCS clients, etc. For example, other devices send requests to LMF with information such as UE ID and LCS correlation ID, requesting LMF to obtain the location information of the device corresponding to the UE ID and LCS correlation ID. After receiving these requests, LMF will trigger interactions, such as positioning processes, to obtain location information and other positioning-related data.

[0368] It should be noted that the number and time of LMF interaction may vary depending on the different request methods in the third information (request information or subscription information), different conditions for data reporting, different data collection methods, different data limiting information, etc. For example:

[0369] Past period: LMF selects appropriate positioning-related data based on the data obtained from historical interactions; specifically, LMF may not interact in this case, but directly use the historical positioning-related data stored locally (such as recent, short-term, half-year, or long-term positioning-related data).

[0370] Future time period: In the future time period, LMF interacts. For example, in the future time period, LMF receives a request for location information of other devices and interacts with UE and other devices.

[0371] Step 306: LMF selects positioning-related data that meets the requirements.

[0372] Specifically, LMF selects data that meets the conditions as target data (ie, positioning-related data) based on data limitation information, area information and other information in the third information.

[0373] It should be noted that the time point and method of LMF selection may be different depending on the request method (request or subscription) in the third information, the data limitation information, etc. For example:

[0374] Request information + past time period, LMF selects the target data based on the data obtained from historical interactions; specifically, LMF can only use locally stored historical positioning-related data (such as recent, short-term, half-year, or long-term positioning-related data, etc.), and after receiving the request message, select the data that meets the data limitation information and other information as the target data for reporting.

[0375] Request information + future time period. When the future time period expires, all data that meet the conditions within the time period are selected as target data. For example, if the data limitation information in the request message received by LMF is a future time period, LMF selects all data that meet the conditions within the time period as target data.

[0376] Subscription information + future time period, select each group of data that meets the conditions in the future time period as the target data. LMF determines the target data by judging whether the collected data meets the data limitation information and other information.

[0377] It should be noted that, to determine whether the data meets the data limitation information and other information, it is possible to determine whether the information of the collected data matches the data limitation information. For example, whether the location of the collected data is within the regional information, that is, whether it is within the regional range; whether the device generating the collected data matches the target data source type; whether the generation time of the collected data matches the target time information, or whether it is within the target time period; whether the data type of the collected data matches the target data type, whether the generation method of the collected data (such as the positioning method of the collected data) matches the target data generation method, etc.

[0378] Step 307-step 309, LMF sends the second message carrying positioning related data to NWDAF through AMF and GMLC;

[0379] Specifically, LMF sends the second information carrying the positioning related data to AMF, AMF sends the second information to GMLC, and GMLC sends the second information to NWDAF;

[0380] Step 310: LMF sends a second message carrying positioning related data to NWDAF;

[0381] It should be noted that steps 307 to 309 are applied to request messages, while step 310 is applied to subscription messages. LMF can directly feedback positioning-related data to NWDAF, GMLC and other devices based on information such as the address information of the notification target in the subscription message.

[0382] Application Scenario 2: Regional Information and Passive Data Collection Based on Cell Granularity

[0383] like Figure 4 As shown in the figure, the specific implementation process includes:

[0384] Step 401-step 405, same as step 301-step 305;

[0385] The difference is that the first information carries area information based on cell granularity.

[0386] Step 406: LMF sends a second request message to AMF, requesting to obtain the cell corresponding to the target area.

[0387] Step 407: AMF sends the cell information of the cell corresponding to the target area to LMF.

[0388] It should be noted that step 406 and step 407 are optional steps.

[0389] Step 408 to step 412 are the same as step 306 to step 310.

[0390] Application 3: Regional information and active data collection based on latitude and longitude granularity or cell granularity

[0391] like Figure 5 As shown in the figure, the specific implementation process includes:

[0392] Step 501 to step 503 are the same as step 301 to step 303, or the same as step 401 to step 403;

[0393] The difference is that the first information is used to indicate active data collection.

[0394] Step 504: AMF determines that active data collection is required;

[0395] Step 505: AMF sends the third information to the selected LMF.

[0396] Specifically, after searching for network elements and determining the selected LMF, the AMF sends the third information to the selected LMF. The third information can be sent through services such as Nlmf_Location_DetermineLocation.

[0397] It should be noted that the third information carries terminal identification information.

[0398] Step 506, LMF determines that active data collection is required;

[0399] Step 507: LMF sends a first request message to AMF, requesting to obtain the terminal identification information corresponding to the target area;

[0400] Step 508: AMF feeds back the terminal identification information of the terminal corresponding to the target area;

[0401] Step 509: LMF interacts with devices such as UE / PRU / RAN;

[0402] Step 510 - Step 514 are the same as Step 306 - Step 310 .

[0403] Application Scenario 4: Network Element Registration and Search

[0404] like Figure 6 As shown in the figure, the specific implementation process includes:

[0405] Step 601: LMF registers with NRF to register its capability information.

[0406] For example, LMF can send a registration request message to NRF, such as sending it through Nnrf_NFManagement_NFRegisterRegister message. After receiving the registration request message, NRF stores the network element registration information of LMF and sends a response message (which can be sent through Nnrf_NFManagement_NFRegister response message) to notify LMF that the registration is successful. Specifically, when LMF sends a registration request message to NRF, in addition to its own identification information (NF instance ID, FQDN or IP address of NF, network element instance identification information), NF type, network element type and other information, it can also include at least one of the following:

[0407] The LMF supports the capability indication of data collection at regional granularity, which is used to indicate that the network element can collect positioning-related data information in a certain area based on the information at a certain regional granularity;

[0408] The area information corresponding to the LMF is used to indicate the service range covered by the LMF, such as GAD shape information, cellID, TA information, etc.

[0409] Capability information to support AI positioning;

[0410] Capabilities to support proactive data collection;

[0411] Capabilities to support training data collection;

[0412] The time frame supporting data collection;

[0413] AI positioning-related capability information.

[0414] Step 602: AMF sends a search request message or a network element discovery request to NRF to find an LMF that meets the conditions.

[0415] For example, AMF sends a network element discovery request (e.g., Nnrf_NFDiscovery_Request service).

[0416] Optionally, the search request message or the network element discovery request needs to include a network element type, that is, used to indicate that the network element to be searched is a network element such as LMF responsible for location-related service management, and optionally, at least one of the following may be carried:

[0417] An indication of supporting data collection capability at a regional granularity, used to indicate that the network element being searched needs to support data collection capability at a regional granularity;

[0418] Area information, such as GAD shape information, cell ID, TA information, etc.

[0419] Capability information to support AI positioning;

[0420] Capabilities to support proactive data collection;

[0421] Capabilities to support training data collection;

[0422] The time frame supporting data collection;

[0423] The communication device to be searched needs to support AI positioning-related capability information.

[0424] Step 603: The LMF feeds back network element information of the LMF that meets the conditions;

[0425] For example, the identification information of the LMF that meets the conditions can be fed back, for example, the identification information can be NF instanceID, FQDN or IP address of NF, network element instance identification information, etc.

[0426] Optionally, the network element information may be sent via the Nnrf_NFDiscovery_Request response.

[0427] It should be noted that the embodiment of the present application enables NWDAF to obtain positioning-related data of different data types from LMF at a regional granularity, thereby improving data acquisition efficiency.
