Abstract
The present invention proposes a solution in the area of HSDPA flow control. It proposes an improvement to transport network congestion detection and avoidance. The improvement proposes to use a measurement of incoming bitrate to determine the reduction of bitrate after a transport network congestion event. The advantage is that high bitrate reduction is only used when it is necessary; otherwise only small bitrate reduction is used, which results in small oscillation, and consequently higher transport network utilization.
