ZXC10-MSCVLR信令处理子系统R2模块的研究及实现
|
摘要
发展中国家的通信设备市场是通信行业的新兴市场,主要集中在亚洲的大部分国家、非洲的全部、拉美和东欧一些国家,这些国家数量很多,目前占全球通信设备市场的20%多,未来这些国家的市场份额将会上升到30%多,而欧美通信设备企业并不十分重视这些市场。作为国际标准信令的R2协议就是基于这些新兴市场的。R2是随路信令的一种,它满足半自动及全自动业务的各种要求,在国际上有较广泛的应用。
为了开拓国际市场,我们开发和实现了基于ITU-T标准的R2信令系统,实现局间线路信令和寄发器信令通过E1接口的发送和接收,接续控制,并且实现和其他各种局间信令的互通。在本系统的基础上可以再次开发基于各国标准的R2信令系统,以满足各个国家的需求。
本文首先介绍了ZXC10系统的组成结构,接着介绍了R2信令的一些基本知识。接下来本文总体设计R2信令系统:根据R2与其他信令模块的关系,本系统采用了半呼叫的软件结构思想,并且提出了其开发目标、设计思想和接口定义。在开发过程中,我们运用了模块化的设计方法,将该系统划分为多个的独立的模块分别进行开发,对其中重要模块的开发原理、处理流程和关键函数的实现作了详细介绍,特别是信令处理模块、桥接模块和过负荷控制模块。接下来介绍了如何搭建该系统的测试环境,对其进行基本功能和相关性能测试,并对测试结果进行分析。最后总结了全文,并提出了对未来的展望。
Those markets of the communications facilities in developing countries are the burgeoning markets in the communications industry, centralized mainly in the most Asian countries, the entire African countries and some countries in Latin America and East Europe. There are many such countries, but they only occupied the 20% markets of the global communications facilities at present which will rise to 30% in the future. However, the communications enterprises in the Occident do not think much of these markets. As the international standard signaling, R2 is based on these markets. As one of the channel associated signaling, R2 meets all kinds of demands in the semiautomatic or automatic operations and has wide applications in the international area.
In order to exploit the international markets, we develop and realize the R2 signaling system based on the ITU-T standard. This system realizes the functions of transmitting and receiving the line and register signal by the E1 interface, controlling connection and interconnection between different signals. On the foundation of this system, we can develop different R2 signaling systems based on different state standards to fulfill different state requirements.
Firstly, the thesis introduces the component structure of the ZXC10 system and some basic concepts of the R2 signal. Secondly, it designs the whole R2 signaling system. According to the relationship between R2 and other signaling modules, this system uses the concept of software structure which is called half-call and presents the development objective, design idea and the definitions of the interfaces. During the developing process, the design method of modularization is used. It is divided into several independent modules and each module is achieved respectively. The developing principle, transacting flow and some key functions of some important modules are explained in detail, especially the modules of signaling transaction, bridge connection and overload control. Thirdly, it illuminates how to set up the testing environment and makes some basic function tests and relevant performance tests.
At last, the thesis is concluded and the directions of further work are presented.
