摘要电话通信是双向的实时通信,用户完成通话需要经历多个状态的变化。
利用网络模拟电话通信,以客户机/服务器模式来模拟程控交换机的服务功能,通过网络服务器代替的程控交换机完成呼叫处理中经历的各个接续过程,利用客户机实现电话终端的呼叫功能。程序要反映呼叫处理方法和处理过程中可能经历的各种状态,并能够提供多种服务,能够进行局间呼叫。
使用Visual studio C#作为系统编写的环境,他能提供简单易操作的界面系统,完善的指令控制语句,类和对象,方便调用系统本身自带的配置文件等等。精简的程序让人一看就懂,便于修改利于程序功能的扩展。21819
论文主要描述了本课题的开发背景,系统分析,代码编写,以及系统函数的调用等等。

Title Use Network to Simulate Basic
Telephone Service
Abstract
Telephone communication is a kind of two-way real-time communication, the user completes the call to go through changes in multiple states.
Analog telephone communication using the Internet, client / server model to simulate the program controlled switch services, Instead of the program - controlled switches via the network server to complete the process for each successive call handling experience, the use of telephone calling features to achieve the client terminal. Program to reflect the various states may experience call processing method and process, and can provide a variety of services that can be inter-office calls.
Use Visual studio C # written as a system environment, it can provide a simple and easy to operate interface system, perfect command control statements, classes and objects, easy call system itself comes with configuration files, and so on. Streamlined procedures make one easy to understand, easy to modify features conducive to the expansion of the program.
Paper describes the background of the topic development, systems analysis, coding, and system function calls, and so on.
Keywords program control switch network server
