Summary:
Next-generation cellular networks are expected to support a wide range of communication technologies and user devices. Under such conditions, proper modelling of user traffic and system performance evaluation is of major importance. In this paper, we employ mathematical modelling techniques to analyse the performance of a single CDMA cell under the presence of user-generated multirate Poisson traffic. We also explicitly consider different traffic priority classes in the system. The considered model, enables us to determine the resource occupancy of the cellular system at different system states and to accurately calculate call blocking probabilities for different services. In particular, we describe the CDMA system as a continuous-time Markov chain and derive formulas for system state probabilities.We also perform a thorough simulation experiments to validate the accuracy of the derived equations.
