【摘要】：相比模拟对讲机,数字对讲机具有频率利用率高、话音质量好、业务能力强、易于加密等特点,是对讲机发展的必然趋势。目前,国内外缺乏数字对讲机空中接口协议解析的相关设备,不能有效解析数字对讲机空中接口协议信息。数字对讲机空中接口协议的解析能实现不同厂商数字对讲机的互通性测试。因此,数字对讲机空中接口协议解析的研究与实现具有重要意义。本文在综述了国内外空中接口协议解析的研究现状的基础上,首先分析了数字对讲机空中接口协议栈结构,描述了数字对讲机空中接口协议突发结构和帧结构,给出了数字对讲机空中接口协议监测系统的组成,设计了数字对讲机空中接口协议解析软件的主流程、数字对讲机空中接口协议数据包解析的主流程和子流程、协议解析软件与协议监测仪间的接口以及数据包解析模块与数据包过滤模块间的接口;然后,在Visual Studio 2010软件平台中,利用MFC应用程序框架,开发了数字对讲机空中接口协议解析软件,并基于Wireshark插件技术,利用C语言,开发了数字对讲机空中接口协议解析插件,实现了数字对讲机空中接口协议短数据业务、语音业务和控制信息的协议解析功能;最后,对数字对讲机空中接口协议解析软件的短数据解析功能、语音解析功能、控制信息解析功能进行测试,测试结果表明,数字对讲机空中接口协议解析软件实现了数字对讲机空中接口协议短数据、语音和控制信息的协议解析功能,满足设计要求。
[Abstract]:Compared with analog walkie-talkies, digital interphone has the characteristics of high frequency utilization, good voice quality, strong business ability and easy encryption, which is the inevitable trend of the development of interphone. At present, the domestic and foreign lack of the digital interphone air interface protocol analysis related equipment, can not effectively analyze the digital interphone air interface protocol information. The analysis of the air interface protocol of the digital interphone can realize the interworking test of the digital interphone made by different manufacturers. Therefore, the research and implementation of air interface protocol analysis for digital interphone is of great significance. On the basis of summarizing the research status of air interface protocol analysis at home and abroad, this paper first analyzes the structure of digital interphone air interface protocol stack, describes the burst structure and frame structure of digital interphone air interface protocol. The composition of the digital interphone air interface protocol monitoring system is given. The main flow chart of the digital interphone air interface protocol analysis software, the main process and sub-flow of the digital interphone air interface protocol packet analysis are designed. The interface between protocol analysis software and protocol monitor and the interface between packet resolution module and packet filter module, and then, in the Visual Studio 2010 software platform, the application program framework of MFC is used. Based on the Wireshark plug-in technology and C language, the digital interphone air interface protocol analysis plug-in is developed, and the short data service of the digital interphone air interface protocol is realized. Finally, the short data analysis function, voice analysis function and control information analysis function of the air interface protocol analysis software of digital interphone are tested, and the test results show that, The digital interphone air interface protocol analysis software has realized the digital interphone air interface protocol short data, the speech and the control information protocol analysis function, satisfies the design request.
