摘　　要：根据从移动运营商的移动智能网中采集到的真实数据,分析了“神州行”预付费业务用户通话时长的分布规律。分析结果表明，指数分布与样本数据的经验分布之间存在较大差异，不适合用来描述通话时长规律；经验分布可以用一个混合分布描述，它由两个单点分布和两个对数正态分布的加权和分布组成。类似的结论对于移动虚拟专用网（VPN）业务的通话时长也成立，它对移动智能网的性能分析具有重要意义。According to the real data collected from the mobile intelligent netwo＆ of mobile operators, the distribution law of call duration of pre-paid service is studied. The analytical results indicate that there are great disparities between exponential distribution and empirical distribution of samples and using exponential distribution to describe the call duration is not suitable. The empirical distribution can be described by a mixture of distributions, which is composed of two singlepoint distributions and a weight sum of two lognormal distributions. Similar conclusion can be given for mobile virtual private network service. It has great significance for the performance analysis of mobile intelligent network.
