【摘要】：集群通信系统,即无线专用调度通信发展迅速,由于其专用性要求高,使得各个系统相互兼容存在很大问题,在有些方面无法满足用户的需求。随着数字集群移动通信网络建设的日趋完善,尤其是专业数字集群系统(PDT)等满足中国国情并具有我国自主知识产权的数字集群通信标准的出现,厂家系统互通互联以及向下兼容模拟系统等问题有了很大改善。因此,对各数字集群协议标准及系统间相互兼容问题进行研究具有重要意义。本文详述了PDT数字集群基站协议子系统的设计,实现了PDT协议与陆上集群无线电(TETRA)协议间的相互解析。首先分析了国内外的发展现状及应用前景,重点介绍了相关的关键技术,包括本系统所需的PDT数字集群系统、系统的总体架构,为本系统的开发奠定基础。然后,设计实现了PDT基站协议子系统,包括基站控制器(BSC)侧和基站收发信机(BSR)侧,其中BSC侧主要是对PDT结构信令与TETRA消息交互的实现,而BSR侧主要是对PDT结构信令的接收转发功能的实现。最后,在ETRA平台基础上,实现了登记、单呼等功能。在实现PDT系统基站软件协议子系统基础上,利用MFC编写显示模块显示信令在系统内的解析过程。用协议分析软件pdtAnalyser解析信令,以及SecureCRT查看系统运行日志,对三者的数据进行分析对比,验证了PDT基站软件协议子系统的信令解析的正确性。
[Abstract]:Trunked communication system, that is, wireless private scheduling communication, is developing rapidly. Due to its high requirement of specificity, there are many problems in compatibility between different systems, which can not meet the needs of users in some aspects. With the development of digital trunking mobile communication network, especially the professional digital trunking system (PDT), the digital trunking communication standard, which meets China's national conditions and has its own intellectual property rights, has emerged. Factory system interconnection and down-compatible analog systems have been greatly improved. Therefore, it is of great significance to study the standards of digital trunking protocols and the compatibility between systems. In this paper, the design of PDT digital trunked base station protocol subsystem is described in detail, and the mutual analysis between PDT protocol and terrestrial trunking radio trunking protocol is realized. Firstly, this paper analyzes the development situation and application prospect at home and abroad, and introduces the relevant key technologies, including the PDT digital trunking system needed by the system, the overall structure of the system, which lays the foundation for the development of the system. Then, the PDT base station protocol subsystem is designed and implemented, including the base station controller (PDT) side and the base station transceiver (BSR) side, in which the BSC side is mainly for the implementation of PDT structure signaling and TETRA message interaction. The BSR side is mainly the realization of the receiving and forwarding function of the PDT structure signaling. Finally, on the basis of ETRA platform, the functions of registration and single call are realized. Based on the realization of the software protocol subsystem of the base station of the PDT system, the display module is written by MFC to display the parsing process of the signaling in the system. The protocol analysis software pdtAnalyser is used to analyze the signaling and the SecureCRT to view the system operation log. The correctness of the signaling parsing of the PDT base station software protocol subsystem is verified by the analysis and comparison of the three data.
