【摘要】:專用通信網(wǎng)通常運(yùn)用于一些特殊行業(yè)或單位內(nèi)部,能夠滿足安全生產(chǎn)、組織管理、任務(wù)調(diào)度指揮等。當(dāng)今,隨著社會(huì)經(jīng)濟(jì)的發(fā)展和信息技術(shù)的進(jìn)步,專用網(wǎng)的用途也在發(fā)生著變化。而專用交換機(jī)作為專用通信網(wǎng)中的核心設(shè)備,負(fù)責(zé)模擬話機(jī)、無線用戶、SIP電話接入及網(wǎng)絡(luò)中的綜合業(yè)務(wù)的交換控制,其中模擬用戶作為專用網(wǎng)交換機(jī)中的基本用戶,其承載著大量的呼叫任務(wù)。本論文主要研究的是專用交換機(jī)呼叫處理軟件中模擬用戶信令的實(shí)現(xiàn),具體包括用戶摘掛機(jī)信令的實(shí)現(xiàn)、信號(hào)音的產(chǎn)生、模擬用戶軟件和維護(hù)管理軟件結(jié)構(gòu)的設(shè)計(jì)與實(shí)現(xiàn)。本文首先對(duì)專用網(wǎng)通信和專用交換機(jī)結(jié)構(gòu)進(jìn)行了研究;其次研究了模擬用戶信令接續(xù)的基本過程,對(duì)模擬用戶信令各部分進(jìn)行了分析,設(shè)計(jì)了呼叫控制實(shí)體,并用有限狀態(tài)機(jī)對(duì)呼叫控制過程進(jìn)行了描述;然后用C語言實(shí)現(xiàn)了模擬用戶信令呼叫處理的各模塊的功能及模塊間的關(guān)聯(lián);最后通過編寫測(cè)試用例,對(duì)該軟件進(jìn)行測(cè)試,即將模擬用戶信令的呼叫處理任務(wù)向呼叫控制軟件發(fā)送信令原語,呼叫控制軟件運(yùn)行之后會(huì)輸出對(duì)應(yīng)的信令原語。本課題使用的硬件平臺(tái)主控板的中央處理器是美國摩托羅拉公司的MPC8086芯片,而軟件平臺(tái)是嵌入式Vx Works操作系統(tǒng),開發(fā)和編譯的環(huán)境是風(fēng)河公司的Tornado2.2。
[Abstract]:Private communication network is usually used in some special industries or units, which can meet the requirements of production safety, organization and management, task scheduling and command, etc. Nowadays, with the development of social economy and information technology, the use of private network is changing. As the core equipment in the private communication network, the private exchange is responsible for the switching control of analog telephone, wireless users, SIP telephone access and integrated services in the network, in which the analog users are the basic users in the private network switches. It carries a large number of call tasks. This paper mainly studies the implementation of analog subscriber signaling in call processing software of private exchange, including the implementation of user off-hook signaling, the generation of signal sound, the design and implementation of analog user software and maintenance management software structure. In this paper, the architecture of private network communication and private switch is studied. Secondly, the basic process of analog subscriber signaling connection is studied, and each part of analog subscriber signaling is analyzed, call control entity is designed, and the call control process is described by finite state machine (FSM). Then, the function of each module and the relation between the modules are realized by C language. Finally, the software is tested by writing test cases, that is, the call processing task of simulating the user signaling sends signaling primitive to the call control software. After the call control software runs, the corresponding signaling primitive will be output. The central processor of the main control board of the hardware platform used in this subject is the MPC8086 chip of Motorola Company of America, while the software platform is embedded Vx Works operating system. The development and compilation environment is the Tornado2.2. of Fenghe Company.
