The allocation of scarce resources to support realtime multimedia services with different quality of service (QoS) requirements is a fundamental problem in wireless cellular networks. In this paper, we propose a new call admission control (CAC) and resource reservation scheme for cellular-based multimedia wireless networks. The well-known CAC guard channel policy is modified to be applicable for different traffic classes with diverse QoS requirements. The proposed scheme is modeled as M/M/C/C queueing system and the performance measures, call blocking probability and call dropping probability are computed
