ABSTRACT:
A method of managing a data packet queue in a buffer associated with the radio layers of a wireless network, the buffer storing packets prior to their transmission over the radio interface. The method comprises defining minimum and maximum threshold levels for the packet queue, and for a data packet received by the buffer 1) performing a congestion avoidance procedure if the buffer queue exceeds said maximum threshold level, or 2) not performing said procedure if the buffer queue is less than said minimum threshold level, or 3) if the buffer queue lies between said maximum and minimum thresholds, performing said congestion avoidance procedure for said packet, and not performing the procedure for at least one or more subsequent packets.
