Abstract: This application provides a satellite communication method and an apparatus. The method may include: A session management network element obtains an identifier list. The identifier list includes identification information of one or more terminal devices that access a satellite in a satellite backhaul manner. The session management network element configures a forwarding rule for a user plane network element on the satellite. The forwarding rule is used to offload, to an access network device corresponding to the terminal device, a data packet whose destination address is included in an address of the terminal device corresponding to the identifier list. Based on the foregoing solution, a terminal device that supports local switching in the satellite can perform communication through local switching in the satellite, so that a delay can be reduced and user experience can be improved.

Abstract: An access network device receives characteristic information of a first live media stream included in a switching request from a terminal device. The access network device or a user plane network element determines, based on the characteristic information, the first live media stream corresponding to the characteristic information of the first live media stream. Therefore, the access network device or the user plane network element switches a media stream sent to the terminal device, to be specific, switches the live media stream sent to the terminal device from a second live media stream to the first live media. Both the second live media stream and the first live media stream correspond to the access network device or the user plane network element. According to the method, media stream switching can be completed on the access network device side or the user plane network element side.
