N2 - The wide-band code division multiple access (WCDMA) based 3 G and beyond cellular mobile wireless networks are expected to provide a diverse range of multimedia services to mobile users with guaranteed quality of service (QoS), The main contribution of this paper is to design and analyze a novel dynamic priority call admission control (DP-CAC) that can be able to achieve a better balance between system utilization and quality of service provisioning. More importantly, the analytical model of this system is valid for the real-time (RT) and non-real-time (NRT) calls having different bit-rate (i.e. different bandwidth requirements), channel holding time, time out, and E b/No requirements. Its performance is compared with another two call admission control strategies, referred to as the complete partitioning CAC (CP-CAC) and the queuing priority CAC (QP-CAC), The DP-CAC analytical model can be used easily to derive the analytical model of the QP-CAC and to the CP-CAC. We present numerical examples to demonstrate the performance of the proposed CAC algorithms and we show that analytical and simulation results are in total agreement. Results also indicate the superiority of DP-CAC as it is able to achieve a better balance between system utilization and quality of service provisioning.
