摘　　要：文章针对现有的以Poisson过程作为输入业务流模型分析系统性能的不足,提出采用马尔可夫调制泊松过程(MMPP)作为输入业务流来分析系统的呼叫阻塞率和掉话率。数值和仿真结果表明,MMPP能够较好的对蜂窝移动网中的业务输入流近似建摸,它考虑了业务流本身的相关特性和突发特性,可以更加准确的用于分析系统性能。In this paper, we present MMPP model as the input traffic models to analyze blocking probability and dropping probability, so as to compensate the shortcomings of the existing performance analysis based on Poisson process. Numerical results and simulations show that MMPP can be used for modeling the input traffic in wireless cellular network very well. In this model, the correlation and bursty characteristic of the traffic are considered and more accurate results can be obtained.
