| Abstract: | This paper presents a novel approach for designing a call-admission control (CAC) algorithm for code-division multiple-access CDMA) networks with arbitrary call-arrival rates. The. design of the CAC algorithm uses global information; it incorporates e call-arrival rates and the user mobilities across the network and guarantees the users' quality of service (QoS) as well as prespecific blocking probabilities. On the other hand, its implementation in each cell uses local information; it only requires the number f calls currently active in that cell. We present several cases for a nontrivial network topology where our CAC algorithm guarantees QoS and blocking probabilities while achieving significantly higher throughput than that achieved by traditional techniques. We so calculate the network capacity, i.e., the maximum throughput f r the entire network, for prespecified blocking probabilities and QoS requirements. [ABSTRACT FROM AUTHOR] |
