【摘要】：隨著通信技術的迅速發(fā)展,近些年來,數(shù)字集群通信系統(tǒng)在全世界得到了普遍應用,行業(yè)競爭日趨激烈。TETRA是我國信息產(chǎn)業(yè)部推薦使用的數(shù)字集群技術的行業(yè)標準,為了更好地滿足市場的需求,新技術和新業(yè)務的開發(fā)及應用顯得尤為重要。短數(shù)據(jù)業(yè)務是一般TETRA系統(tǒng)中的一塊短板,相對于語音業(yè)務起步較晚。目前系統(tǒng)運營商和開發(fā)商對這項業(yè)務有了越來越多的重視。本文所設計的短數(shù)據(jù)應用協(xié)議SDPP (Short Data Point to Point)能夠實現(xiàn)手臺設備與控制中心之間互相收發(fā)短數(shù)據(jù)的功能。本文首先簡單介紹了數(shù)字集群通信的發(fā)展背景和研究現(xiàn)狀,繼而又介紹了TETRA標準數(shù)字集群通信的發(fā)展現(xiàn)狀和前景,在此基礎上進一步研究其系統(tǒng)結構,從而定位短數(shù)據(jù)應用協(xié)議作用的具體模塊；其次,歸納了本文所設計協(xié)議要用到的幾種技術,確定開發(fā)及運行環(huán)境；再次,重點闡述了此協(xié)議的具體內(nèi)容,及協(xié)議模塊的實現(xiàn)細節(jié),包括邏輯功能、模塊接口、算法和數(shù)據(jù)結構等;最后對協(xié)議進行測試,給出了測試用例和部分數(shù)據(jù)截圖,并分析了測試結果。目前該研究成果已經(jīng)成功地用于TETRA數(shù)字集群通信系統(tǒng)的設計和開發(fā),并且通過了測試人員的嚴格測試,已投入商用。測試結果表明其功能及性能能夠滿足客戶提出的一系列需求。
[Abstract]:With the rapid development of communication technology, digital trunking communication system has been widely used in the world in recent years, and the industry competition is increasingly fierce. TETRA is the industry standard of digital trunking technology recommended by the Ministry of Information Industry of China. In order to better meet the needs of the market, the development and application of new technology and new business is particularly important. Short data service is a short board in general TETRA system, which starts later than voice service. At present, system operators and developers have more and more attention to this business. The short data application protocol SDPP (Short Data Point to Point) designed in this paper can realize the function of sending and receiving short data between handstand equipment and control center. This paper first introduces the background and research status of digital trunking communication, then introduces the development and prospect of TETRA standard digital trunking communication, and then further studies its system structure. In order to locate the specific module of short data application protocol; secondly, summarized the design of the protocol to use several technologies to determine the development and operation environment; again, the specific content of this protocol is expounded. And the implementation details of the protocol module, including logic function, module interface, algorithm and data structure, etc. Finally, the protocol is tested, the test cases and some data screenshots are given, and the test results are analyzed. At present, this research result has been successfully used in the design and development of TETRA digital trunking communication system, and has passed the strict test of the testers, and has been put into commercial use. The test results show that its function and performance can meet a series of customer requirements.
