Abstract：There is a great demand on multimedia services in wireless networks. Capacity analysis of a multi-service CDMA communication system is employed in which the concept of equivalent bandwidth is introduced, and then an optimal Call Admission Control and Resource Allocation algorithm (CAC-RA) is proposed. in CAC-RA, multimedia traffic is classified into two classes: real-time trafficand non real-time traffic, and manage Call Admission Control (CAC), handoff scheme and resource allocation (RA) together by adopting Markov Decision Process model for adaptive real-time applications, queuing model for non real-time applications ,and nonlinear programming for the proposed revenue function which combine these two models. Numerical results reveal that the proposed CAC-RA scheme adapts itself well to multi-service CDMA networks by achieving reasonable utilization of resources.
