摘要
分析了软交换的话务特性,建立了软交换的一般话务量模型,即分别考虑呼叫的到达服从Bernoulli分布、Poisson分布和Pascal分布的情况。在此基础上,给出了软交换系统排队过程的系统状态图。最后,推导出软交换一般话务量计算的数学公式,为软交换系统的分析与设计提供了理论上的依据。
Based on the analysis of the traffic attribute of softswitch system, this paper introduces a general traffic model of softswitch, i.e. respectively taking three arrival processes - - - Bernoulli process, Poisson process and Pascal process into consideration. Based on this, a queuing system status diagram of softswitch system is given. And the formula of calculating softswitch traffic is deduced, which provides theoretical bases for the design and analysis of a softswitch system.
