GPRS通信性能检测系统

基于Microsoft Visual Studio.NET平台,利用C#网络编程技术,开发了GPRS通信性能测试软件,并构建了GPRS通信性能检测平台,它可同时检测GPRS网络中的时延、丢包率以及传输速率三项通信性能指标。首先介绍了系统的硬件组成和系统基本检测原理并重点分析了数据帧格式和数据解析机制,然后简要介绍了系统测试软件的操作界面和主要功能,最后对系统检测表明,GPRS通信过程中主要有三种不同的网络拥塞情况并可通过控制数据发送速率来保证通信质量。

GPRS Communication Performance Testing System

With C# network programming and based on the platform of Microsoft Visual Studio.NET,the software of GPRS communication performance testing is developed,and the GPRS communication performance testing platform is constructed,this platform could simultaneously test three communication performance indexes of GPRS network,including delay,packet loss and transmission rate.Firstly,the hardware composition of the system and the testing principles are given,and the format of data frames and the mechanism of data parsing emphatically analyzed.Then the operation interface and the functions of testing software are briefly described.Finally,the system testing results indicate that in the process of GPRS communication,there are three different congestion situations,and the communication quality could be ensured by controlling the data sending speed.
