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 (52)) AND A NODE B (54). THE SYSTEM MONITORS CERTAIN CRITERIA AND, IF NECESSARY, ADAPTIVELY INCREASES OR DECREASES THE DATA FLOW BETWEEN THE RNC (52) 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.
