Abstract
A method for sending an end marker, a device, and a system, where the method includes receiving, by a source access node (AN) through a source path between the source AN and a core-network user-plane device, a first end marker sent by the core-network user-plane device. The method further includes generating, by the source AN, N second end marker(s) based on the first end marker, where N is a number of source data radio bearers (DRBs) corresponding to the source path, and sending, by the source AN, the N second end marker(s) to a target AN through a forwarding path corresponding to the source path.
Claims20
A method for sending an end marker, wherein the method comprises:
- 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.
A communication system, comprising:
- a core-network user-plane device;
- and
- a source access node (AN) configured to:
- receive, through a source path between the source AN and the core-network user-plane device, a first end marker from the core-network user-plane device, wherein the first end marker indicates that sending downlink data of a user equipment (UE) on the source path is completed;
- generate N second end markers based on the first end marker, wherein N is greater than or equal to 2;
- and
- send 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.
