COGNITIVE FLOW CONTROL BASED ON CHANNEL QUALITY CONDITIONS

摘要

PROBLEM TO BE SOLVED: To provide a system and method which improve performance of a wireless transmission system by intelligent use of control of data flow between a radio network controller (RNC) (12) and a Node B (54).

SOLUTION: 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 prior to handover of a High Speed Downlink Shared Channel (HS-DSCH).
