Method for creating configuration information and communication apparatus

A communication apparatus, comprising a processor, wherein the processor is coupled to a memory, the memory is configured to store a computer program, and the processor is configured to execute the computer program stored in the memory to:

• receive a first request message from a network exposure function network element, wherein the first request message is used to request to create application configuration information, and the first request message comprises identification information of an application function network element;
• determine subscription data of one or more target terminal devices based on the identification information of the application function network element;
• create the application configuration information based on the subscription data of the one or more target terminal devices;
• and
• send, to the network exposure function network element, a first response message in response to the first request message.

A system comprising:

• a data management network element and a network exposure function network element,
• wherein the data management network element is configured to:
• receive a first request message from a network exposure function network element, wherein the first request message is used to request to create application configuration information, and the first request message comprises identification information of an application function network element;
• determine subscription data of one or more target terminal devices based on the identification information of the application function network element;
• create the application configuration information based on the subscription data of the one or more target terminal devices;
• and
• send, to the network exposure function network element, a first response message in response to the first request message;
• wherein the network exposure function network element is configured to:
• send the first request message to data management network element;
• and
• receive the first response message.
