The presence of mixed traffic (i.e., voice and data) in GSM/GPRS networks raises many problems regarding dimensioning aspects. An important and critical element of these networks is represented by the radio resources. In this paper we study three models which characterize the mixed traffic process in a cell when the available radio resources are shared according different strategies between voice and data. All the strategies we consider are based on the Partial Partitioning allocation scheme. Our combined FR (full-rate) and HR (half-rate) voice traffic technique and the DHR (dynamic allocation technique) voice technique implement an optimal use of resources based on half-rate mobiles allocation capability and re-packing mechanisms. We also define performance parameters suitable for dimensioning purposes, like blocking probabilities, average throughput per user and average total throughput. We present a series of experiments which prove that the presented voice traffic allocation techniques improve the GPRS throughput.
