[0265] In the embodiment of the present disclosure, the first network element sends a first response message to the access network element. The first response message includes first analysis data, and the first analysis data includes the credibility of the data.

[0266] Exemplarily, the first analysis data includes data used for terminal mobility analysis and the credibility of the data, which can reflect the accuracy of the data used for terminal mobility analysis. For example, the credibility of the data used for terminal mobility analysis is 90%, which can reflect that the accuracy of the data used for terminal mobility analysis is high.

[0267] Exemplarily, the first analysis data includes data used for terminal communication analysis and the credibility of the data, which can reflect the accuracy of the data used for terminal communication analysis. For example, the credibility of the data used for terminal communication analysis is 90%, which can reflect that the accuracy of the data used for terminal communication analysis is high.

[0268] Exemplarily, the first analysis data includes data used for business experience analysis and the credibility of the data, which can reflect the accuracy of the data used for business experience analysis. For example, the credibility of the data used for business experience analysis is 90%, which can reflect that the accuracy of the data used for business experience analysis is high.

[0269] Exemplarily, the first analysis data includes data used for abnormal behavior analysis and the credibility of the data, which can reflect the accuracy of the data used for abnormal behavior analysis. For example, if the credibility of the data used for abnormal behavior analysis is 90%, it can reflect that the accuracy of the data used for abnormal behavior analysis is high.

[0270] Exemplarily, the first analysis data includes data used for performing statistical analysis of motion behavior and the credibility of the data, which can reflect the accuracy of the data used for performing statistical analysis of motion behavior. For example, the credibility of the data used for performing statistical analysis of motion behavior is 90%, which can reflect that the accuracy of the data used for performing statistical analysis of motion behavior is high.

[0271] In some embodiments, an access network element receives a first response message sent by a first network element, and the first response message includes first analysis data of a second network element. When the first analysis data is data related to an AI model, the access network element can use the first analysis data to perform AI-related processing, such as training an AI model, managing an AI model (including model monitoring, etc.), and reasoning about an AI model.

[0272] In some embodiments, an access network element receives a first response message sent by a first network element, the first response message including first analysis data of a second network element. If the first analysis data is network operation data, the access network element may use and / or consider the network operation data to perform relevant network operations. For example, network operations include resource allocation, coverage and capacity optimization, load balancing, mobility optimization, user experience optimization, network slicing optimization, etc.

[0273] It can be understood that the analysis data is stored in the second network element (NWDAF), and the analysis data includes at least one of the following: data used for terminal mobility analysis; data used for terminal communication analysis; data used for service experience analysis; data used for abnormal behavior analysis; data used for motion behavior statistical analysis; and data credibility.

[0274] The data includes at least one of: AI model, model training data set, model update data set, model input data, and model output data.

[0275] In one possible implementation, an access network network element involves the need to perform terminal mobility analysis and needs to obtain data for performing terminal mobility analysis from a second network element. However, related technologies do not support the access network network element obtaining analysis data from the second network element. Therefore, in an embodiment of the present disclosure, the access network network element obtains analysis data from the second network element through the first network element, for example, by sending a first request to the first network element and receiving a first response from the first network element to obtain analysis data from the second network element. In this way, the access network network element can obtain data for performing terminal mobility analysis from the second network element and then perform terminal mobility analysis.

[0276] Among them, the access network network element involves the need to perform terminal mobility analysis, and it is necessary to obtain data for performing terminal mobility analysis from the second network element, for example, it is necessary to obtain an AI model for performing terminal mobility analysis, or it is necessary to obtain a model training data set for performing terminal mobility analysis, or it is necessary to obtain a model update data set for performing terminal mobility analysis, or it is necessary to obtain model input data for performing terminal mobility analysis, or it is necessary to obtain model output data for performing terminal mobility analysis.

[0277] It should be noted that the access network element may also involve the need to perform terminal communication analysis, and the need to obtain data for terminal communication analysis from the second network element, or may also involve the need to perform service experience analysis, and the need to obtain data for service experience analysis from the second network element, or may also involve the need to perform abnormal behavior analysis, and the need to obtain data for abnormal behavior analysis from the second network element, or may also involve the need to perform motion behavior statistical analysis, and the need to obtain data for motion behavior statistical analysis from the second network element, and so on.

[0278] S206A: The first network element determines second analysis data after the first analysis data is updated.

[0279] In the embodiment of the present disclosure, the first analysis data may be updated, and the first network element may determine the second analysis data after the first analysis data is updated.

[0280] In some embodiments, the first network element obtains the second analysis data after the first analysis data is updated, including: receiving an update notification message sent by the second network element, wherein the update notification message includes the second analysis data after the first analysis data is updated; and obtaining the second analysis data according to the update notification message.

[0281] In an embodiment of the present disclosure, the first network element can receive an update notification message sent by the second network element, and the update notification message includes the second analysis data after the first analysis data is updated. Thus, the first network element can determine the second analysis data after the first analysis data is updated based on the update notification message.

[0282] It should be noted that S206A is optional. For example, when there is no update to the first analysis data or when there is an update to the first analysis data, the first network element does not need to actively notify the access network network element, but the first network element needs to provide the access network network element with the second analysis data after the first analysis data is updated based on the first request of the access network network element.

[0283] S207A: The first network element sends second analysis data to the access network element.

[0284] In an embodiment of the present disclosure, after the first network element determines the second analysis data after the first analysis data is updated, it can send the second analysis data to the access network network element. Thus, the access network network element can obtain the second analysis data after the first analysis data is updated, and update the first analysis data in a timely manner.

[0285] It should be noted that S207A is optional. For example, the first analysis data does not contain the updated second analysis data, that is, the first network element does not need to send the second analysis data to the access network element.
