接入控制(CAC)是移动通信网络无线资源管理中一个重要的组成部分,它依据一定的准则决定是否允许呼叫接入。文中首先概述了CAC策略的内容,描述了基本的接入控制算法,然后分析了一种资源预留的TD-SCDMA接入控制算法,最后讨论了在非对称业务环境下的接入控制策略。
Access Control (CAC) is an important part of wireless resource management in mobile communication network. It decides whether to allow call access according to certain criteria. The paper first outlines the content of CAC strategy, describes the basic access control algorithm, and then analyzes a TD-SCDMA access control algorithm with resource reservation. Finally, it discusses the access control strategy in asymmetric service environment.
