This application provides a reflective QoS flow characteristic-based communications method and apparatus. In the method, an access-network network element sends first information to a core-network network element, where the first information is used to indicate whether a data packet has a reflective QoS flow characteristic; and the access-network network element determines, based on the first information, whether there is a need to send a QoS flow identifier to a terminal. In this way, signaling overheads are reduced.
A communication method for handover, comprising:
A communication system, comprising:
A communication apparatus, comprising:
A communication apparatus comprising a memory and a processor, the memory stores program code, and the processor is configured to invoke the program code to send a handover request message to a target base station, wherein the handover request message comprises an identifier of a data radio bearer (DRB) and information indicating whether to configure a service data adaptation protocol (SDAP) header for the DRB;
