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. For example, if primary authentication succeeds, it may be considered that AKMA authentication also succeeds. 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.

Abstract: Embodiments of this application provide a communication method and an apparatus to resolve a PC5 unicast establishment failure due to inconsistency between security parameters of terminal devices in a V2X scenario with security negotiation introduced into a PC5 unicast establishment procedure. The communication method includes: A first direct communication discovery name management function network element obtains a security parameter of a first terminal device. A security parameter is required for establishing a PC5 connection between the first terminal device and a second terminal device. The first direct communication discovery name management function network element receives a security parameter of the second terminal device from a second direct communication discovery name management function network element and determines, based on whether the security parameter of the first terminal device matches the security parameter of the second terminal device, whether the first terminal device and the second terminal device support mutual communication.
