Multi-stream data transmission method, apparatus, and system, and anchor
First Claim
1. A multi-stream data transmission system, comprising at least one access node, an anchor, and a wireless backhaul device, wherein data transmission is performed between each access node and the anchor by using a wireless backhaul link established by using the wireless backhaul device;
- whereinthe anchor is configured to;
obtain resource availability data of all data transmission paths from user equipment (UE) to the anchor, wherein the resource availability data comprises resource data of wireless backhaul links between all access nodes and the anchor;
determine multiple target data transmission paths according to the resource availability data of all the data transmission paths;
transmit service data to the UE in a multi-stream manner by using the multiple target data transmission paths, wherein the multiple target data transmission paths comprise a corresponding wireless backhaul link that is established between a target access node and the anchor by using the wireless backhaul device, and the target access node is an access node that is in the at least one access node and that transmits the service data;
when resources of each target data transmission path are greater than a specified value, distribute data packets of the service data to a transmission path with low resource consumption; and
when resources of a target data transmission path are less than the specified value, distribute high-priority data packets to a transmission path with sufficient resources, and distribute low-priority resources to a transmission path with strained resources; and
the target access node is configured to send the service data to the UE by using the corresponding wireless backhaul link.
