發(fā)布時間：2018-12-12 03:35
【摘要】：專用通信網通常運用于一些特殊行業(yè)或單位內部,能夠滿足安全生產、組織管理、任務調度指揮等。當今,隨著社會經濟的發(fā)展和信息技術的進步,專用網的用途也在發(fā)生著變化。而專用交換機作為專用通信網中的核心設備,負責模擬話機、無線用戶、SIP電話接入及網絡中的綜合業(yè)務的交換控制,其中模擬用戶作為專用網交換機中的基本用戶,其承載著大量的呼叫任務。本論文主要研究的是專用交換機呼叫處理軟件中模擬用戶信令的實現,具體包括用戶摘掛機信令的實現、信號音的產生、模擬用戶軟件和維護管理軟件結構的設計與實現。本文首先對專用網通信和專用交換機結構進行了研究;其次研究了模擬用戶信令接續(xù)的基本過程,對模擬用戶信令各部分進行了分析,設計了呼叫控制實體,并用有限狀態(tài)機對呼叫控制過程進行了描述;然后用C語言實現了模擬用戶信令呼叫處理的各模塊的功能及模塊間的關聯(lián);最后通過編寫測試用例,對該軟件進行測試,即將模擬用戶信令的呼叫處理任務向呼叫控制軟件發(fā)送信令原語,呼叫控制軟件運行之后會輸出對應的信令原語。本課題使用的硬件平臺主控板的中央處理器是美國摩托羅拉公司的MPC8086芯片,而軟件平臺是嵌入式Vx Works操作系統(tǒng),開發(fā)和編譯的環(huán)境是風河公司的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.
