Classification: CPC H | IPC H

Claim 15:
16. A core network user plane device comprising:
at least one processor, the at least one processor is coupled to a memory and a transceiver, the memory storing instructions that instruct the at least one processor to perform operations comprising:
receiving, by using the transceiver, from a core network control plane device a request message, the request message notifies the core network user plane device to change a route, the request message comprises an identity of a protocol data unit (PDU) session and an identity of a quality of service (QoS) flow;
changing the route of a data packet of the QoS flow; and
sending an end marker packet to a master radio access network device; and
sending a second end marker packet to a secondary access network device, wherein the second end marker packet instructs the secondary access network device to send, to the core network user plane device, a data packet that is of the QoS flow and that is sent by a terminal to the secondary access network device.
