Abstract: This application provides a communication method and apparatus, and relates to the communication field, to ensure proximity based service relay communication security. In the method, proximity based service authentication information #1 provided by a data management network element is used, so that a remote terminal and a network may authenticate each other and generate a proximity based service key used for communication between the remote terminal and a relay terminal. Further, the remote terminal device and the relay terminal device derive a communication protection key for a PC5 connection (namely, a connection between the remote terminal and the relay terminal) based on the proximity based service key, which may include at least one of an encryption key and an integrity protection key, so that proximity based service relay communication security is ensured, and a case such as user information leakage caused by an attack is avoided.

Abstract: An authentication management function AUSF receives an authentication request message from an access and mobility management function AMF, where the authentication request message carries a subscription concealed identifier SUCI. The AUSF sends an authentication vector get request message to a unified data management UDM function, where the authentication vector get request message carries the SUCI. The AUSF receives an authentication vector get response message from the UDM, where the authentication vector get response message includes authentication and key management for application AKMA indication information. The AUSF generates, based on the AKMA indication information, an authentication and key management for application-key identifier based on a routing indicator RID in the SUCI.

Abstract: In a method for configuring a policy for user equipment (UE), a PCF network element receives policy information of the UE from a first network element. The policy information of the UE indicates a current policy of the UE. The PCF network element sends configuration information to the UE based on the policy information of the UE, and the configuration information instructs the UE to update the policy of the UE. The policy control function network apparatus then sends to the first network apparatus update information that comprises either the configuration information or an identifier of the configuration information.
