Method and apparatus for subscribing to analytics of model transfer status in network, and readable storage medium

A method for subscribing to an analytics of model transfer status in a network, wherein the method is applied to a network data analytic function (NWDAF), and the method comprises:

• receiving, directly or through a network exposure function (NEF), a first message sent by an application function (AF), wherein the first message is configured to request a subscription of analytics information of artificial intelligence/machine learning (AI/ML) model transfer status in the network;
• sending, according to a parameter requested in the first message, a second message to other network function(s) of a 5G core network (5GC NF(s)), wherein the second message is configured to collect data for analyzing the AI/ML model transfer status in the network;
• receiving the data of the AI/ML model transfer status sent by the other network function(s) of the 5G core network (5GC NF(s)), and analyzing the data of the AI/ML model transfer status to obtain the analytics information of the AI/ML model transfer status;
• wherein the analytics information is configured to adjust a network policy parameter and/or information of an application layer model through the AF.

An apparatus for subscribing to an analytics of model transfer status in a network, wherein the apparatus comprises a memory, a transceiver, and a processor;

• the memory is configured to store computer programs;
• the transceiver is configured to send and receive data under a control of the processor;
• the processor is configured to read the computer programs in the memory and perform the following operations:
• sending a first message to a network data analytic function (NWDAF) directly or through a network exposure function (NEF), wherein the first message is configured to request a subscription of analytics information of artificial intelligence/machine learning (AI/ML) model transfer status in the network;
• receiving, directly or through the NEF, the analytics information of the AI/ML model transfer status sent by the NWDAF, wherein the analytics information is determined by the NWDAF according to received data of the AI/ML model transfer status sent by other network function(s) of a 5G core network (5GC NF(s));
• wherein the analytics information is configured to adjust a network policy parameter and/or information of an application layer model.
