发布时间：2018-12-12 03:35
【摘要】：专用通信网通常运用于一些特殊行业或单位内部,能够满足安全生产、组织管理、任务调度指挥等。当今,随着社会经济的发展和信息技术的进步,专用网的用途也在发生着变化。而专用交换机作为专用通信网中的核心设备,负责模拟话机、无线用户、SIP电话接入及网络中的综合业务的交换控制,其中模拟用户作为专用网交换机中的基本用户,其承载着大量的呼叫任务。本论文主要研究的是专用交换机呼叫处理软件中模拟用户信令的实现,具体包括用户摘挂机信令的实现、信号音的产生、模拟用户软件和维护管理软件结构的设计与实现。本文首先对专用网通信和专用交换机结构进行了研究;其次研究了模拟用户信令接续的基本过程,对模拟用户信令各部分进行了分析,设计了呼叫控制实体,并用有限状态机对呼叫控制过程进行了描述;然后用C语言实现了模拟用户信令呼叫处理的各模块的功能及模块间的关联;最后通过编写测试用例,对该软件进行测试,即将模拟用户信令的呼叫处理任务向呼叫控制软件发送信令原语,呼叫控制软件运行之后会输出对应的信令原语。本课题使用的硬件平台主控板的中央处理器是美国摩托罗拉公司的MPC8086芯片,而软件平台是嵌入式Vx Works操作系统,开发和编译的环境是风河公司的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.
