【摘要】：集群通信系統(tǒng),即無線專用調(diào)度通信發(fā)展迅速,由于其專用性要求高,使得各個系統(tǒng)相互兼容存在很大問題,在有些方面無法滿足用戶的需求。隨著數(shù)字集群移動通信網(wǎng)絡建設的日趨完善,尤其是專業(yè)數(shù)字集群系統(tǒng)(PDT)等滿足中國國情并具有我國自主知識產(chǎn)權(quán)的數(shù)字集群通信標準的出現(xiàn),廠家系統(tǒng)互通互聯(lián)以及向下兼容模擬系統(tǒng)等問題有了很大改善。因此,對各數(shù)字集群協(xié)議標準及系統(tǒng)間相互兼容問題進行研究具有重要意義。本文詳述了PDT數(shù)字集群基站協(xié)議子系統(tǒng)的設計,實現(xiàn)了PDT協(xié)議與陸上集群無線電(TETRA)協(xié)議間的相互解析。首先分析了國內(nèi)外的發(fā)展現(xiàn)狀及應用前景,重點介紹了相關(guān)的關(guān)鍵技術(shù),包括本系統(tǒng)所需的PDT數(shù)字集群系統(tǒng)、系統(tǒng)的總體架構(gòu),為本系統(tǒng)的開發(fā)奠定基礎。然后,設計實現(xiàn)了PDT基站協(xié)議子系統(tǒng),包括基站控制器(BSC)側(cè)和基站收發(fā)信機(BSR)側(cè),其中BSC側(cè)主要是對PDT結(jié)構(gòu)信令與TETRA消息交互的實現(xiàn),而BSR側(cè)主要是對PDT結(jié)構(gòu)信令的接收轉(zhuǎn)發(fā)功能的實現(xiàn)。最后,在ETRA平臺基礎上,實現(xiàn)了登記、單呼等功能。在實現(xiàn)PDT系統(tǒng)基站軟件協(xié)議子系統(tǒng)基礎上,利用MFC編寫顯示模塊顯示信令在系統(tǒng)內(nèi)的解析過程。用協(xié)議分析軟件pdtAnalyser解析信令,以及SecureCRT查看系統(tǒng)運行日志,對三者的數(shù)據(jù)進行分析對比,驗證了PDT基站軟件協(xié)議子系統(tǒng)的信令解析的正確性。
[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.
