Call Admission Control (CAC) is an important mechanism in mobile networks. Many works have been done on GSM/GPRS and on UMTS system with mixed voice and data. However, CAC models and wireless communication proposed in the literature are represented with a uni-dimensional Markov chain, in general based on voice calls in order to reduce the state-space of the chain. Another drawback of those studies is lack of the synchronization between mobiles and servers. In this paper, we aim to evaluate the performance of a CAC scheme which takes into account voice connections, synchronous and asynchronous data connections. This scheme can be represented by a multi-dimensional Markov chain with a very large state-space. Thus, we propose to use Stochastic Well formed Petri Nets (SWN) to model the system interaction which consists of several mobiles, gateways, cells and servers. Performance measures are carried-out using symbolic simulation.
