[0394] In step 101, an access network element (e.g., NG-RAN) sends an NWDAF Info Request message (see the second request in the above embodiment, the same below) to the AMF, where the message is used to request available NWDAF information. Based on the message, the AMF sends NWDAF info to the NG-RAN.

[0395] In some embodiments, the AMF may obtain information of at least one NWDAF instance through the NRF, wherein the information may be used for selecting the NWDAF instance.

[0396] In some embodiments, the NWDAF Info Request information is included in a non-UE related NGAP message, for example, an NGAP NG Setup Request message or a RAN Configuration Update message.

[0397] In some embodiments, if the NGAP NG Setup Request message includes an NWDAF Info Request, the AMF shall include the NWDAF information (if supported) in the NG SETUP RESPONSE message.

[0398] In some embodiments, if the NWDAF Info Request is included in the RAN CONFIGURATION UPDATE ACKNOWLEDGE message, the AMF shall include the NWDAF information (if supported) in the RAN CONFIGURATION UPDATE message.

[0399] In step 102, the AMF sends NWDAF info to the access network element (see the second response in the above embodiment, the same below), where the NWDAF info is used by the access network element to select a suitable NWDAF to obtain analysis data (including statistical and / or prediction information).

[0400] In some embodiments, the second response is included in a non-terminal related NGAP message, for example, an NGAP NG Setup Response message, a RAN CONFIGURATION UPDATE ACKNOWLEDGE message, or an AMF Configuration Update message.

[0401] In some embodiments, if NWDAF Info is included in the NG SETUP RESPONSE message, the access network element shall store this information (if supported) and use it for NWDAF selection.

[0402] In some embodiments: If NWDAF Info is included in the AMF CONFIGURATION UPDATE ACKNOWLEDGE message, the access network element shall store this information (or replace the old information) and use it for NWDAF selection.

[0403] In some embodiments, the NWDAF info information includes information about at least one NWDAF instance, and the information about each NWDAF instance includes at least one of the following information:

[0404] -NWDAF identifier, used to identify NWDAF or NWDAF instance, for example, it can be FQDN, IP address, instance ID, routing ID, etc.

[0405] -Analytics ID, used for supported network slice information;

[0406] -Supported Analytics Delay, used to indicate supported analytics delay;

[0407] -NWDAF Capabilities, which indicates the capabilities of NWDAF, including but not limited to analytics aggregation capability, analytics metadata provisioning capability, and accuracy checking capability;

[0408] -AI / ML model information, which indicates information related to the AI / ML model.

[0409] Step 103: When necessary, the access network element selects an appropriate NWDAF according to the NWDAF info to obtain analysis data. The access network element sends an uplink X protocol transmission message to the AMF (see the first transmission message in the above embodiment, the same below).

[0410] The uplink X protocol transmission message may include at least one of the following information:

[0412] -UE identity, used to indicate that the message is related to a specific UE.

[0413] - X-Protocol-PDU, including an X-Protocol message (see the first request in the above embodiment).

[0414] The X protocol is a communication application protocol between the NG-RAN node and the NWDAF. In some embodiments, the X protocol is used by the NG-RAN node and the NWDAF to request and / or subscribe to analysis data.

[0415] In some embodiments, the purpose of the specific protocol transmission procedure is to transmit specific protocol signaling between the access network element and the NWDAF via a next generation (NG) interface.

[0416] In some embodiments, the downlink terminal-associated protocol-specific transmission process (i.e., the transmission process of the first response) and the uplink terminal-associated protocol-specific transmission process (i.e., the transmission process of the first request) utilize terminal-associated signaling. The terminal-associated signaling is used to support analysis reporting and AI / ML-related operations using the terminal-associated signaling's protocol-specific message.

[0417] In some embodiments, the downlink non-terminal-associated specific protocol transmission process (i.e., the transmission process of the first response) and the uplink non-terminal-associated specific protocol transmission process (i.e., the transmission process of the first request) use non-terminal-associated signaling. Non-terminal-associated signaling is used to support analysis and reporting of specific protocol messages using non-terminal-associated signaling and AI / ML-related operations.

[0418] In step 104, the AMF transmits the received X protocol-PDU to the designated NWDAF, wherein the X protocol message (see the first request in the above embodiment) may include information obtained by analyzing data or information related to model operations.

[0419] In step 105, the NWDAF sends a response X protocol-PDU (see the first response in the above embodiment) to the AMF based on the received X protocol-PDU. The X protocol-PDU may include information obtained by analyzing data or information related to model operations.

[0420] Step 106: The AMF sends a downlink X protocol transmission message to the access network element (see the second transmission message in the above embodiment).

[0421] The downlink X protocol transmission message may include at least one of the following information:

[0422] -NWDAF identifier, used to indicate the NWDAF with which communication is desired;

[0423] -UE identity, used to indicate that the message is related to a specific UE.

[0424] - X Protocol-PDU, including X Protocol messages.

[0425] The access network element can perform AI-related operations, resource allocation and / or network optimization based on the information in the X-Protocol-PDU.

[0426] In the embodiment of the present disclosure, the above method can enable the access network network element to select appropriate core network functions and obtain comprehensive statistical data or predictive data from the core network's big data nodes (such as NWDAF) for AI-related operations or network optimization of the access network network element, which can improve the performance of the access network network element, improve resource utilization, reduce energy consumption, etc.
