[0520] The following is an exemplary introduction to the above methods in the above embodiments.

[0521] In some embodiments, the LMF (i.e., the core network device 103 in each embodiment of the present application) sends a measurement request (i.e., the first message in each embodiment of the present application) to an inferring gNB (i.e., the first access network device 101 in each embodiment of the present application) to notify it of potential input-related information from other gNBs. The LMF sends measurement requests to other gNBs (i.e., the second access network device 102 in each embodiment of the present application), instructing them to send measurement results to the inferring gNB. The other gNBs send the measurement results to the inferring gNB. The inferring gNB performs AI inference based on the received measurement results and / or its own measurement results, and sends the output to the LMF for UE position calculation.

[0522] 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.

[0523] In step 101, the LMF sends a first message to the inference gNB, where the first message includes first information indicating AI model input TRP information. If the first information is included in the first message, the inference gNB receives TRP measurement results from other gNBs based on the information as input for model inference.

[0524] The first message is an NRPPa message, for example, a measurement request message, but not limited thereto.

[0525] The first information includes a first identifier (the first identifier is used to uniquely identify a measurement process within the LMF, such as an LMF measurement ID) and one or more AI input TRP information, each TRP information including at least one of the following information: the gNB ID where the TRP is located; the TRP ID; the Cell ID.

[0526] In step 102, the LMF sends a fourth message to the other gNB, where the fourth message is used to instruct the other gNB to perform positioning measurements for AI inference. The second message includes the identifier of the inference gNB. If the second message includes the identifier of the inference gNB, the other gNB sends the positioning measurement results to the indicated inference gNB based on the identifier.

[0527] The second message is an NRPPa message, for example, a measurement request message, but not limited thereto.

[0528] Optionally, step 101 and step 102 may occur simultaneously, or the order of occurrence is not limited.

[0529] In step 103, the other gNB sends a second message to the inference gNB, where the second message is used to transmit AI positioning model input information (e.g., positioning measurement results). The second message includes the AI ​​positioning model input information. If the second message includes the AI ​​positioning model input information, the inference gNB performs AI model inference based on the information and outputs the corresponding inference result.

[0530] The second message is an XnAP message, such as a positioning measurement report message, a positioning measurement information message, a positioning measurement update message, a data collection report message, a data collection update message, etc.

[0531] Among them, the model input information of the AI ​​positioning includes at least one of the following information: an LMF identifier, used to indicate that the positioning process is initiated by a specific LMF; a first identifier, the first identifier is used to uniquely identify a measurement process within the LMF (for example, an LMF measurement ID); information on positioning measurement data, including measurement results of one or more TRPs.

[0532] Each TRP measurement result includes at least one of the following information:

[0533] The gNB identity of the TRP is used to indicate the gNB identity of the TRP performing the measurement, such as the NG-RAN node identity;

[0534] TRP identifier, used to uniquely identify a TRP within a gNB;

[0535] A cell identifier, used to indicate the cell where the TRP is located;

[0536] TRP measurement data, used to indicate the data of the TRP measurement, wherein the TRP measurement data includes at least one of the following information: TRP measurement data value (i.e., in each embodiment of the present application), for example, including but not limited to the following measurement values: CIR, PDP, DP, Angle of Arrival, SRS-RSRP, RTOA, gNB Rx-Tx Time Difference, Z-AoA, multiple UL-AoA; timestamp; used to indicate the time of measurement; measurement quality, used to indicate the quality of measurement, for example, it can be measurement accuracy information; measurement beam information, used to indicate the receiving beam information when receiving the uplink positioning signal, for example, it can be SSB, PRS; positioning signal type, used to indicate the type of received positioning signal, for example, it can be SRS, pos-SRS, etc.; LoS / NLoS information, used to indicate LoS or NLoS information when receiving the positioning signal; measurement purpose, used to indicate the purpose of the measurement value, such as model training or inference.

[0537] The Inference gNB performs centralized AI positioning inference based on the received AI positioning model input information and generates the AI ​​positioning inference results.

[0538] Step 104: The inference gNB sends a third message to the LMF, where the third message is used to transmit the result of AI positioning inference. The third message includes the output result of the AI ​​positioning model inference.

[0539] The third message is an NRPPa message, for example, a measurement report message or a measurement update message.

[0540] In some embodiments, the third message includes a TRP Measurement Response List information element (TRP Measurement Response List IE), where the information element (IE) includes model output results of one or more TRPs, each TRP model output result being the result of AI positioning model inference based on model input information of a specific TRP. The model output result corresponding to each TRP includes the gNB ID of the TRP.

[0541] In some embodiments, the LMF (i.e., the core network device 103 in various embodiments of the present application) sends a measurement request (i.e., the first message in various embodiments of the present application) to an inferring gNB (i.e., the first access network device 101 in various embodiments of the present application) to notify it of potential input-related information from other gNBs. The inferring gNB sends the measurement request to the other gNB (i.e., the second access network device 102 in various embodiments of the present application). The other gNB sends measurement results to the inferring gNB. The inferring gNB performs AI inference based on the received measurement results and / or its own measurement results and sends the output to the LMF for UE position calculation.

[0542] 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.

[0543] Step 201 is consistent with step 101 and is not repeated here. The difference is that if the first message includes the first information, the inference gNB sends a measurement request to other gNBs based on the first information to receive measurement results from other gNBs as input for model inference.

[0544] In step 202, the inference gNB sends a fifth message to the other gNB, requesting the other gNB to perform positioning measurements for AI inference. The fifth message includes the second information. If the fifth message includes the second information, the other gNB performs positioning measurements based on the second information and sends the positioning measurement results to the inference gNB as AI input information.

[0545] The fifth message is an XnAP message, for example, a positioning measurement request message or a data collection request message, but is not limited thereto.

[0546] The second information includes at least one of the following information: positioning measurement request information, used to instruct other gNBs to perform positioning measurements and reports; an LMF identifier, used to indicate the LMF identifier that initiates the positioning measurement; and a first identifier, used to uniquely identify a measurement process within the LMF.

[0547] Step 203 is the same as step 103 and will not be repeated here.

[0548] Step 204 is the same as step 104 and will not be described again here.

[0549] In some embodiments, the LMF (i.e., the core network device 103 in each embodiment of the present application) sends a measurement request (i.e., the first message in each embodiment of the present application) to an inferring gNB (i.e., the first access network device 101 in each embodiment of the present application) to notify it of potential input-related information from other gNBs (i.e., the second access network device 102 in each embodiment of the present application). The LMF initiates measurement requests to other gNBs to collect measurement results from them. The LMF sends the measurement results of the other gNBs to the inferring gNB. The inferring gNB performs AI inference based on the received measurement results and / or its own measurement results, and sends the output to the LMF for UE position calculation.

[0550] 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.

[0551] Step 301 is the same as step 101 and is not repeated here. The difference is that if the first message includes the first information, the inference gNB, based on the first information, temporarily does not report or perform AI inference after performing its own positioning measurement. Instead, it waits to receive the TRP measurement results of other base stations sent by the LMF and uses the TRP measurement results of other base stations as inference input to perform the AI ​​positioning inference process.

[0552] In steps 302-303, the LMF initiates a positioning measurement process to instruct other base stations to perform positioning measurements and report the measurement results, which will be used in the AI ​​positioning inference process.

[0553] In step 304, the LMF sends a second message to the inference gNB, where the second message is used to transmit the positioning measurement results of other gNBs. The second message includes AI positioning model input information. If the second message includes AI positioning model input information, the inference gNB performs the AI ​​positioning model inference process based on the AI ​​positioning model input information and / or its own positioning measurement results as model inputs, and generates a result.

[0554] The second message is an NRPPa message, for example, an AI measurement request message, but not limited thereto.

[0555] Step 305 is the same as step 104 and will not be repeated here.
