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.
