1. A method comprising:
sending, by a core-network user-plane device through a source path between a source access node (AN) and the core-network user-plane device, a first end marker to the source AN, wherein the first end marker indicates that sending downlink data of a user equipment (UE) on the source path is completed;
receiving, by the source AN, the first end marker;
generating, by the source AN, N second end markers based on the first end marker, wherein N is greater than or equal to 2; and
sending, by the source AN, the N second end markers to a target AN through N forwarding paths,
wherein the N forwarding paths are for forwarding, to the target AN, data of the UE received through the source path.
