Data processing method and apparatus

An apparatus comprising:

• a memory configured to store program instructions;
• and
• a processor configured to execute the program instructions to cause the apparatus to:
• determine identification information of one or more submodels related to a target model;
• send a first request message to a network element corresponding to the identification information of the one or more submodels, wherein the first request message comprises the identification information of the one of more submodels;
• receive a first response message from the network element, wherein the first response message comprises a first output result obtained through calculation by the network element by using the one or more submodels, and the first output result reflects a value;
• and
• obtain the target model through training that is based on the first output result of the network element corresponding to the identification information of the one or more submodels;
• wherein to determine the identification information of the one or more submodels related to the target model, the apparatus further caused to:
• determine, based on a local configuration, the identification information of the one or more submodels related to the target model;
• or
• determine the network element that is related to the target model and that has a confidentiality requirement;
• and obtain the identification information of the one or more submodels from the network element having the confidentiality requirement.

A communication system, comprising a first network data analytics network element and a second network data analytics network element, wherein the first network data analytics network element includes a processor and a non-transitory computer-readable storage medium storing instructions executable by the processor such that the first network data analytics network element is at least configured to:

• determine identification information of one or more submodels related to a target model;
• send a first request message to a network element corresponding to the identification information of the one or more submodels, wherein the first request message comprises the identification information of the one or more submodels;
• receive a first response message from the network element, wherein the first response message comprises a first output result obtained through calculation by the network element by using the one or more submodels, and the first output result reflects a value;
• and
• perform training that is based on the first output result of the network element corresponding to the identification information of the one or more submodels to obtain the target model;
• wherein to determine the identification information of the one or more submodels related to the target model, the first network data analytics network element is further configured to:
• determine, based on a local configuration, the identification information of the one or more submodels related to the target model;
• or
• determine the network element that is related to the target model and that has a confidentiality requirement;
• and obtain the identification information of the one or more submodels from the network element having the confidentiality requirement.
