Abstract: This application provides a communication system, method, and apparatus. The system is applied to implement authentication and key management for applications (AKMA) service-based data transmission between a terminal device and an application function network element. The system includes an AKMA anchor function network element and a network exposure function network element. The network exposure function network element obtains first identification information from a unified data management network element, where the first identification information is used to determine an authentication server function network element corresponding to the terminal device, and sends the first identification information to the AKMA anchor function network element. The AKMA anchor function network element obtains, from the unified data management network element based on the first identification information, identification information of the authentication server function network element corresponding to the terminal device.

Abstract: A communication method and apparatus are provided. The method may include: A mobility management network element receives a transaction identifier of a remote terminal device and a name of a data network from a relay terminal device. The mobility management network element determines a subscription permanent identifier of the remote terminal device based on the transaction identifier, and then sends the subscription permanent identifier and the name of the data network to a session management network element. After receiving the subscription permanent identifier and the name of the data network, the session management network element determines, by using a data management network element based on the subscription permanent identifier and the name of the data network, whether to perform secondary authentication on the remote terminal device. Whether to perform secondary authentication on the remote terminal device can be determined by using the provided solution.
