Data transmission method and system
First Claim
1. A method for transmitting data, comprising:
- when transmitting downlink data, shunting, by a master node, the downlink data at a Radio Link Control (RLC) sublayer to obtain shunted data packets, and sending the shunted data packets to shunting nodes;
processing, by the shunting nodes, the shunted data packets, and sending the processed data packets to a User Equipment (UE); and
when transmitting uplink data, converging, by the master node, data packets sent from a shunting node and data packets sent from a UE, and sending the converged data packets to a core network;
further comprising the step, preceding sending the shunted data packets to the shunting nodes, of;
selecting, by the master node, a shunting node for the UE according to quality of wireless signals transmitted between the UE and the shunting nodes, and sending control plane information of the UE to the selected shunting node.

Abstract
Disclosed is a data transmission method. The method includes that: when downlink data is transmitted, a master node shunts, on a Radio Link Control (RLC) sublayer, the downlink data to obtain shunted data packets, and sends the shunted data packets to shunting nodes; the shunting nodes process the shunted data packets, and send the processed data packets to a User Equipment (UE); and when uplink data is transmitted, the master node converges data packets sent from the shunting nodes and data packets sent from the UE, and sends the converged data packets to a core network. Also disclosed is a data transmission system. With embodiments of the disclosure, mobile communications system is able to provide an optimized service, a higher bandwidth and better performance.
