COGNITIVE FLOW CONTROL BASED ON CHANNEL QUALITY CONDITIONS

摘要

A system and method which improve the performance of a wireless transmission system by intelligent use of the control of the flow of data between a radio network controller (RNC) (12) and a Node B (54). The system monitors certain criteria and, if necessary, adaptively increases or decreases the data flow between the RNC (12) and the Node B (54). This improves the performance of the transmission system by allowing retransmitted data, signaling procedures and other data to be successfully received at a faster rate, by minimizing the amount of data buffered in the Node B (54). Flow control is exerted to reduce buffering in the Node B (54) upon degradation of channel qualities, and prior to a High Speed Downlink Shared Channel (HS-DSCH) handover.
