CDMA网络中综合业务的呼叫接纳控制算法及性能分析

Call Admission Control Arithmetic and Performance Analysis for Integrated Traffic in CDMA Networks

呼叫接纳控制(CAC)是CDMA系统无线资源管理中的重要组成部分,有效的CAC算法能在满足各类业务不同QoS要求的同时,提高资源的利用率。本文对于新呼叫和切换呼叫,提出了一种有效的呼叫接纳控制算法,给予了切换呼叫更高的优先级,并采用Markov链对算法的性能进行了分析。

Call admission control （CAC） is becoming an important composing part of CDMA systems in radio resource management. An efficient call admission control arithmetic is essential to provide QoS guarantees of different services to enhance the utilization of radio resource. In this paper, an efficient call admission control arithmetic is proposed for new call and handoff call, which gives handoff call higher priority , and a Maxkov chain is used to analyze the performance of the call admission control arithmetic.
