  • Call admission control (CAC) is one of the most important parts of resource management in mobile communication systems. It keeps the system work stable by accepting or rejecting users service requests. CAC solves the conflict between the service satisfaction of user and system resource utilization. This paper focuses on the dynamic CAC strategy providing guaranteed fairness in the CDMA systems with non-uniform traffic distribution among cells. A novel CAC strategy, which can support multi-traffic with different QoS requirements and VBR traffic, is proposed based on former research achievements. By adopting greedy algorithm, whether accepting or rejecting a new call request depends on the target Signal-to-Interference of the whole system. Therefore the equilibrium of blocking probability among cells with different arriving rates and the access fairness is guaranteed. It is very significant for practical system applications.
