由于通过无线网络可以很方便地使用网络服务,因此无线网络用户越来越多。与此同时,随着无线网络服务的快速发展,人们对无线网络提供的通信容量提出了很高的要求。如何分析和设定网络参数,提高当前网络的运行效率已成为解决网络服务质量优化的一个重要问题。论文提出了一种描述和分析服务切换策略的概率模型,利用生灭过程来分析基站通信信道在不同使用方式下的状态转移概率模型。通过分析不同信道分配策略所对应的队列模型性能,给出了各种队列使用方法的优缺点,并讨论了无线基站预留信道的使用方式以及预留信道的数量对无线基站运行性能的影响。

With the quick development of wireless networks,more and more people begin using the wireless equipment to access the Internet.On the other side,the service provided by the networks has the requirement of a high QoS of transmission.How to evaluation the performance of a network has become a serious problem.This paper introduces a probability model of the usage of channel of base station.Some schemes of channel allocating have been analyzed in this paper,and it gives the relationship of the blocked-call to the way of channel allocating and the relationship of the blocked-call to the number of reserved channel.
