[0524] The following is an exemplary introduction to the above methods in the above embodiments.

[0525] In some embodiments, the training gNB (i.e., the first access network device 101 in the present invention) requests the LMF (i.e., the core network device 103 in the present invention) to collect positioning data via NRPPa, and the LMF initiates data collection through a traditional positioning process or initiates positioning data collection, and the LMF sends the collected positioning data to the training gNB.

[0526] As an example, please refer to FIG. 6A . In the following steps shown in FIG. 6A , the prior art and the contents irrelevant to the present embodiment are omitted.

[0527] Step 101: The training gNB sends a first message to the LMF, where the first message includes information indicating requirements for data collection.

[0528] The first message is an NRPPa message, and the NRPPa message is used for data collection request. For example, the NRPPa message is a positioning data collection (Positioning Data Collection Required) message.

[0529] The requirement information for indicating data collection includes at least one of the following information:

[0532] Requested positioning data measurements, used as input for positioning AI model training (e.g., CIR, PDP, DP, etc.) and / or legacy positioning measurement requests (e.g., gNB-RxTxTimeDiff, UL-SRS-RSRP, UL-AoA, UL-RTOA, Multiple UL-AoA, UL SRS-RSRPP, etc.);

[0533] The transmission mode of the collected positioning data, for example, periodic or on-demand transmission, or transmission by TRP, or transmission by UE;

[0534] The amount of location measurement data collected;

[0535] The time when the positioning measurement data was collected;

[0536] Base station information for which data collection is requested, used to indicate the base stations for which positioning data collection is required, such as identifiers of one or more base stations;

[0537] The cell information for which data collection is requested is used to indicate the cell for which positioning data collection is required, for example, one or more cell identifiers;

[0538] Request to collect TRP information, including the number and / or type of TRPs.

[0539] In steps 102 to 103, the LMF receives information indicating the need for data collection, and collects the required positioning data from other base stations (ie, the second access network device 102 in the present invention) based on the information.

[0540] In some embodiments, the LMF collects positioning data that meets the conditions during the existing positioning process; in other embodiments, the LMF initiates a positioning process for data collection based on demand information.

[0541] Step 104: The LMF sends a second message to the training gNB, where the second message includes collected positioning data. The collected positioning data is received by the LMF from other base stations.

[0542] The second message is an NRPPa message, which is used to transmit the collected positioning data sent by the LMF to the training gNB. For example, the NRPPa message is positioning data collection information (Positioning Data Collection Information).

[0543] In some embodiments, the collected positioning data may include positioning data measured by one or more base stations; in other embodiments, the collected positioning data includes positioning measurement data of one or more TRPs; in yet another embodiment, the collected positioning data includes positioning data for one or more UEs.

[0549] The gNB performs centralized positioning model training based on the collected positioning measurement data received, and uses the trained model for the AI-assisted positioning process.

[0550] In some embodiments, the training gNB (i.e., the first access network device 101 in the present invention) requests the LMF (i.e., the core network device 103 in the present invention) to collect positioning data through an NRPPa message, and the LMF initiates data collection through a traditional positioning process or the LMF initiates positioning data collection. In addition, the LMF instructs other gNBs (i.e., the second access network device 102 in the present invention) to send the collected positioning data directly to the training gNB.

[0551] As an example, please refer to FIG. 6B . In the following steps shown in FIG. 6B , the prior art and the contents irrelevant to this embodiment are omitted.

[0552] Step 201 is consistent with step 101 and will not be repeated here.

[0553] In step 202, the LMF sends a third message to other base stations, wherein the third message includes data collection request information, and the data collection request information includes the identifier of the training gNB.

[0554] The third message is an NRPPa message, which is used for requesting the collection of positioning data. The NRPPa message may be a positioning measurement request message or a positioning data collection request message.

[0555] Other base stations measure positioning signals based on the data collection request and send the collected positioning data to the base station identified by the training gNB.

[0556] In step 203, the other base stations send a second message to the training gNB, where the second message includes the collected positioning measurement data. The specific content and effect of the collected positioning measurement data are consistent with those in step 104 and are not repeated here.

[0557] The second message is an XnAP message, and the XnAP message is used to transmit positioning measurement data. For example, the XnAP message may be a Positioning Data Collection Information message.

[0558] In some embodiments, the training gNB (i.e., the first access network device 101 in the present invention) directly requests other gNBs (i.e., the second access network device 102 in the present invention) to collect positioning data through XnAP. The other gNBs collect positioning data during the traditional positioning process. The other gNBs check whether the measured positioning data can be used for the requested data collection, and then send the collected data directly to the training gNB.

[0559] As an example, please refer to FIG. 6C . In the following steps shown in FIG. 6C , the prior art and the contents irrelevant to the present embodiment are omitted.

[0560] Step 301: When the training gNB has a positioning data collection requirement, the training gNB sends a first message to other gNBs, where the first message includes positioning data collection request information.

[0561] The first message is an XnAP message, for example, the XnAP message is a data collection request message;

[0562] The positioning data collection request information includes at least one of the following information:

[0563] The measurement identifier for positioning data collection is generated by the training gNB and is used to uniquely identify a data collection task within the training gNB.

[0564] Positioning data collection request indication, used to instruct the training gNB to start or stop positioning data collection;

[0567] Data reporting methods, such as periodic reporting, on-demand reporting, etc.;

[0568] The amount of location measurement data collected;

[0569] Positioning signal configuration for positioning measurement, such as SRS configuration or pos-SRS configuration;

[0570] The time when the positioning measurement data is collected, for example, the length of time or interval of the measurement;

[0571] Other base stations receive the information and perform positioning measurement and reporting based on the information.

[0572] In some embodiments, other base stations, while performing existing positioning processes, select positioning data that meets the data collection criteria as collected positioning data. In some embodiments, other base stations collect positioning data based on positioning measurements requested by the training gNB and collect measurement results as collected positioning data.

[0573] In step 302, the other base stations send a second message to the training gNB, where the second message includes the collected positioning measurement data. The specific content and effect of the collected positioning measurement data are consistent with those in step 104 and are not repeated here.

[0574] The second message is an XnAP message, for example, the XnAP message is a data collection feedback message or a data feedback update message.
