Abstract

The next step in the evolution of UMTS is the Enhanced Uplink or high speed uplink packet access (HSUPA), which is designed for the efficient transport of packet switched data. We propose an analytic modeling approach for the performance evaluation of the UMTS uplink with best-effort users over the enhanced uplink and QoS-users over dedicated channels. The model considers two different scheduling disciplines for the enhanced uplink: parallel scheduling and one-by-one scheduling. Resource Management in such a system has to consider the requirements of the dedicated channel users and the enhanced uplink users on the shared resource, i.e. the cell load. We evaluate the impact of two resource management strategies, one with preemption for dedicated channels and one without, on key QoS-indicators like blocking and dropping probabilities as well as user and cell throughput.
