运用Wireshark排查GPRS终端通信故障的高级分析技术

GPRS终端在用电信息采集系统中被广泛应用于数据传输，主要是由于采用GPRS通信方式省去了通信信道的建设与维护方面的开销投入。在GPRS终端通信异常时，通过简单地更换通信卡，重启终端，或改善网络信号质量等手段往往无法解决问题。文章通过对GPRS终端通信基本原理的介绍。对实际案例的详细分析，讲解如何运用Wireshark对GPRS终端通信过程的网络数据封包进行监测与分析，对GPRS终端的通信故障进行更加专业高效的定位和排查。

Advanced Analysis Techniques of Troubleshooting GPRS Terminal Communication Failure with Wireshark

GPRS terminal is widely applied to data transmission in electric energy data acquisition system, which is due to a huge saving from constructing and maintaining the communication network. In the occurrence of communication failure, simply replaces SIM card, reboots the terminal, or improves the signal quality is not always going to work. Therefore, this article introduces the fundamental communication principle of GPRS terminal, together with detailed illustrates several troubleshooting examples, demonstrates how to use Wireshark to monitor and to analyze network packets during GPRS terminal data transmission, makes more professional and efficient troubleshooting and locating for the communication failure of GPRS terminal.
