应用排队论的理论和方法分析GSM网络的准拥塞状态,进而提出一种缓解网络拥塞的方法。当网络处于准拥塞状态时,在不增加资源的前提下,适当增加服务器的处理时延,就能提高GSM网络容量。应用这种方法的仿真结果表明,当系统网络的利用率大于0.6小于0.8时,采用这个优化算法能够提高系统在单位时间内支持的通信用户数量,增加网络容量,降低系统的呼损率,证明了此算法的有效性及可行性。
Applying the theory and method of queuing theory to analyze the quasi-congestion status of GSM network, and then propose a way to alleviate the network congestion. When the network is in a quasi-congested state, without increasing resources, appropriately increasing the processing delay of the server can increase the GSM network capacity. The simulation results using this method show that when the utilization of the system network is greater than 0.6 and less than 0.8, this optimization algorithm can increase the number of communication users supported by the system per unit time, increase the network capacity and reduce the call loss rate of the system, The effectiveness and feasibility of this algorithm.
