Summary:This application provides a communication method and a communications apparatus, to help control switching of a PDU session, thereby improving system performance. The method includes: determining, by a network device based on switching indication information of protocol data unit PDU sessions established by a terminal in a first network, a target PDU session from the established PDU sessions, where all the established PDU sessions have a same data network name DNN; and sending, by the network device, session information of the target PDU session to a mobility management entity device in a second network.
