基于Petri网的GSM/GPRS性能分析

Performance Analysis of GSM/GPRS With Stochastic Colored Petri Net Modeling

首先介绍了数字蜂窝移动通信中的语音通信业务,分析了语音通信各种行为所满足的分布函数。接下来建立基于Petri网的语音通信业务的模型,研究在3种通道共享机制控制下语音通信的性能。最后利用TimeNET工具对模型加以分析和讨论。

The common methods to analyze the performance of are practical test and emulation.This paper utilized the capability of Petri nets to construct and analyze the models of mobile wireless communication.We first introduced the service of voice communication in digital cellular mobile communications and gave the distribution functions of the behaviors in voice communication.Then we constructed the model of voice communication based on Petri nets and gave the performance about three kind of sharable mechanism.At last,we analyzed and studied the model through the tool TimeNET.
