Within the 3G networks, the HSDPA use a scheduler in the Node B that has to be optimised to differentiate traffic / users to provide the appropriate Quality of Service to everyone. There are several kinds of application / user that need different QoS priorities not only in terms of throughput but also in terms of delay. Most of the algorithms for HSDPA scheduler work based on throughput and some of them also are based on delay but with complicated functions difficult to implement in the HW of the current 3G networks. It is needed to simplify the algorithms. This invention allows a more efficient control of the delay of the traffic involved in the different applications in the 3G networks when going through the HSDPA scheduler and also guarantees the best Quality of Service (QoS) to the customers.
