Abstract
This application discloses a communication method and a communications apparatus, to resolve problems of a long transmission path and a large transmission delay of signaling that are caused because a data network (DN) to which application layer control signaling used to control path switching needs to be transmitted for processing in a process of the path switching is outside a mobile communications network. The method includes receiving, by a first core network device, a request message from a terminal, where the request message is used to request to switch from a multicast mode to a unicast mode to transmit service data to be sent to the terminal. The method further includes indicating, by the first core network device based on the request message, a multicast user plane gateway and/or a service server corresponding to the terminal to send, to the terminal in the unicast mode, the service data to be sent to the terminal.
