Revenue and delay control in 3G service network

In the future, 3G networks will be required to provide support for a number of different types of traffic and services, each with its own particular characteristics and quality of service parameters, including e.g. guaranteed bandwidth, jitter, and latency. In this paper, an adaptive weighted fair queue (WFQ) based algorithm for 3GPP traffic class allocation is presented and studied in the single node case. This node can be any RAN or core network user plane node. The weights in the fixed-point type fast adaptive WFQ algorithm are updated using revenue as a target function. Instead of revenue, also delay or throughput could be used as targets. Due to the adaptive nature of the algorithm, it can operate in non-stationary environments. In addition, it is nonparametric and deterministic in the sense that no assumptions about call density functions or duration distributions are made.
