Communication method and apparatus

A communication system, comprising a session management network element and an application server discovery network element, wherein

• the application server discovery network element is configured to receive an identifier of a target service from a first terminal, obtain an address of a same target application server that needs to be accessed by a plurality of terminals to access the target service, and send the address of the target application server to the first terminal, wherein the plurality of terminals comprise the first terminal, and the obtaining an address of a target application server comprises:
• receiving the address of the target application server from the session management network element;
• and
• the session management network element is configured to send the address of the target application server to the application server discovery network element.

A communication apparatus, comprising at least one processor coupled to at least one memory storing instructions and configured to execute the instructions to cause the apparatus to:

• receive an identifier of a target service from a first terminal;
• obtain an address of a same target application server that needs to be accessed by a plurality of terminals to access the target service, wherein the plurality of terminals comprise the first terminal;
• and
• send the address of the target application server to the first terminal.

A computer program product comprising instructions that are stored on a computer-readable medium and that, when executed by one or more processors, cause an apparatus to:

• receive an identifier of a target service from a first terminal;
• obtain an address of a same target application server that needs to be accessed by a plurality of terminals to access the target service, wherein the plurality of terminals comprise the first terminal;
• and
• send the address of the target application server to the first terminal.
