Abstract
This application provides communication methods and apparatuses. One method comprises: obtaining, by a central unit-user plane node (CU-UP), first information that instructs the CU-UP to map a first data packet to a data radio bearer (DRB) and set a reflective mapping indication field of the first data packet, wherein the first data packet belongs to a quality of service (QoS) flow, and the reflective mapping indication field instructs a terminal device to map an uplink data packet in the QoS flow to the DRB; receiving, by the CU-UP, the first data packet sent by a core network device; setting, by the CU-UP, the reflective mapping indication field of the first data packet; and sending, by the CU-UP to the terminal device on the DRB, the first data packet.
