Classification: CPC H | IPC H

Claim 7:
8. A transmission method comprising:
sending, by a master radio access network device, to a core network control plane device a request message, the request message comprises an identity of a protocol data unit (PDU) session and an identity of a quality of service (QoS) flow, the request message requests changing a route of the QoS flow of the PDU session to a secondary access network device; and
receiving, by the master radio access network device, a first end marker packet from a core network user plane device; wherein the first end marker packet indicates that the core network user plane device no longer sends a data packet of the QoS flow to the master radio access network device; and
sending, by the master radio access network device, a second end marker packet to the 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.
