无线网络呼叫接纳控制算法的研究

Research on Algorithm of Call Admission Control in Wireless Networks

呼叫接纳控制(CAC,Call Admission Control)是无线网络中无线资源管理(RRM,Radio Resource Man-agement)的重要组成部分,是保证用户服务质量(QoS,Quality of Server)和提高系统资源利用效率的重要手段。简要介绍了无线网络资源管理基本模型及CAC目标,重点分析了无线网络中典型CAC算法,最后对CAC算法进一步研究方向进行了展望,这对于无线网络的实际部署与应用具有重要的实际意义。

Call Admission Control （CAC） is an important part of wireless radio resource management and an important means which is assured of Quality of Server （QoS） and is improved of system resource utilization efficiency in wireless networks. It was briefly described of RRM basic model and CAC objectives in wireless networks. At the same time, it was focused on analyzing typical CAC algorithm in wireless networks. Finally, research direction of CAC was looked into the future. All of which is important practical significance and reality necessity when wireless networks is deployed and applied.
