Abstract: A communication method, apparatus, and system are provided, to resolve problems in a conventional technology that an AKMA authentication procedure is complex and signaling overheads are large. Principles of the method are as follows: In a registration procedure of a terminal device, AKMA authentication is implicitly indicated based on primary authentication.

In addition, an AKMA temporary identifier is allocated to the terminal device after AKMA authentication succeeds. According to the method, apparatus, and system in this application, no additional AKMA authentication is required. This simplifies a procedure and reduces signaling overheads.
