Call admission control (CAC) is key to administering quality of service. In this paper, CAC principles are reviewed as they apply to wireless DS-CDMA networks offering multiple classes of service. In such networks, the key distinguishing feature for CAC that leads to cross-layer design issues is the role of SIR. CAC algorithms for multimedia CDMA systems balance the system load such that both physical layer QoS requirements (BER targets) as well as network layer requirements (delays) can be met for each user in the system. This is indicative that optimal joint design of optimization algorithms at the physical layer and admission strategy is highly desirable.
