摘要： Control of a data packet buffer in a communication system is described. Control of a data packet queue in a transmission link is shown. In the queue there is stored a plurality of received data packets that are intended for transmission over a wireless interface. Selected packets are discarded from the queue without the selected packets having been transmitted. A packet is selected for discarding depending on at least the length of time the packet has been stored in the queue. The discarding of a selected packet is effectuated on condition that at least a predetermined time period has elapsed since a previous discarding of a packet has taken place. Such a solution is advantageous in that, for varying transmission bandwidth conditions in the transmission link, it is possible to achieve good link utilization and throughput, while at the same time enabling a low end-to-end delay for packets transmitted in the link.
