Communication method and communications apparatus

A communications apparatus, comprising:

• a processor and a memory;
• wherein
• the memory is configured to store a program;
• and
• the processor invokes the program stored in the memory, to perform the following method:
• obtaining an application information target value of a network slice in a specified location area;
• obtaining a network running information target value of the network slice in the specified location area based on an association relationship between application information and network running information and the application information target value, wherein the association relationship is used to describe the association relationship between the application information and the network running information when a communications service provided by the network slice in the specified location area meets a service level agreement SLA meets a service level agreement (SLA);
• and
• sending the network running information target value to an operation, administration, and maintenance server.

A communications system, comprising:

• a network data analytics function network element, and an operation, administration, and maintenance server;
• wherein
• the network data analytics function network element is configured to:
• obtain an application information target value of a network slice in a specified location area;
• obtain a network running information target value of the network slice in the specified location area based on the association relationship between the application information and the network running information and the application information target value, wherein the association relationship is used to describe an association relationship between application information and network running information when a communications service provided by the network slice in the specified location area meets a service level agreement (SLA);
• and
• send the network running information target value to an operation, administration, and maintenance server;
• and
• the operation, administration, and maintenance server is configured to receive the network running information target value.
