Abstract: This application provides a service data transmission method and a communication apparatus. The method includes: An application server obtains first information of a multicast broadcast service session; and the application server sends data of a service over the multicast broadcast service session based on the first information. In the foregoing technical solution, the application server may determine, based on related information (for example, information of a terminal in the multicast broadcast service session, or information of the multicast broadcast service session) of the multicast broadcast service session, that the data of the service can be transmitted over the multicast broadcast service session. In this way, the data of the service can be transmitted flexibly over the multicast broadcast service session.

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.

Abstract: An address obtaining method includes obtaining, by a third network device, an identifier of a first application from a terminal device. The identifier of the first application indicates a request for obtaining an address of an instance of the first application. The address obtaining method further includes sending, by the third network device, a first message to a first network device, wherein the first message comprises the identifier of the first application, and the first message is useable to request the address of the instance of the first application. The address obtaining method further includes receiving, by the third network device, the address of the instance of the first application from the first network device, and sending the address of the instance of the first application to the terminal device.
