An access control scheme for bursty traffic in CDMA system

In this paper, we examine the traditional power control and associated access control schemes in cellular CDMA systems and analyze their effectiveness for bursty data traffic. We propose a novel access/admission control scheme based on a probabilistic channel usage framework. Simulation results show that the proposed scheme could improve the system capacity considerably without QoS degradation. Compared with existing access control schemes, the algorithm proposed in this paper improves the system capacity by 50% for high traffic load and by 100% for low to medium traffic loads.
