基于IP网络公务电话系统设计与实现毕业论文及附录代码.docxVIP

重庆邮电大学本科毕业设计（论文） -  PAGE 83 - 摘 要 IP网络已经成为全球信息一体化的关键承载网络。随着人们需求的增加，越来越多的业务需要开发，IP网络也必须满足对各种业务的承载。目前，公务电话业务的需求正在下降，于是，公务电话需要增强灵活性，用IP网络承载公务电话成了必然的趋势。 本文设计并实现了一个IP网络公务电话的网络应用软件。运用了VC++6.0平台、MFC的动态链接库。为了在IP网络中承载，我们要满足TCP/IP协议，因此，微软的MFC库里面包含了一种基于Windows的Socket套接字库，在这种套接字可以绑定连接IP网络后可以进行面向连接和面向非连接的通信服务。 本次程序设计实现了单呼和组呼的IP网络公务电话的功能。本文介绍了本次软件设计的框架结构、类图设计、信令机制、操作界面、话机状态以及话机系统线程设计。这些总体设计帮助我们设计出程序的框架结构以及逻辑关系，我们也可以通过这些设计来理解程序的编写过程，帮助我们优化程序。 本文还介绍了这次IP公务电话仿真系统的操作方法和流程，包括初始化配置以及拨号流程。并且着重介绍了组呼和单呼通话建立过程中界面的一些显示过程，帮助我们更好的理解这个系统的操作流程。 最后，本文还对本次设计的关键程序代码进行了解释，特别是对单呼和组呼处理时的程序编写进行了详细的解释。 【关键词】IP网络 公务电话 微软基础类库 套接字  ABSTRACT IP network has become the main bear-netweork of the integration of global information. Along with the increase of the people demand, more and more business need to develop, the IP network must satisfy to bear the various of business. At present, the sevice telephone business is going down, therefore, the service telephone need to enhance the flexibility, bearing service telephone with IP network has become the inevitable trend. This paper designs and realizes an IP network service telephone network application software, using VC++ 6.0 platform and MFC dynamic link library. In order to load in the IP network, we should meet the TCP/IP protocol, therefore, Microsoft MFC repository contains a Socket Character based on Windows, in this kind of Socket can bound and connect IP network, and then provide connection-oriented and communication services for the connection. The program has realized the single call and group call function of the IP network service telephone. This paper introduces the frame structure of the software design, the class diagram design, signaling mechanism, interface design, the design of thread of the telephone system. These designs help us to design a program of the overall design framework structure and logic relations, we can also understand programs written by these design process, and also help us to optimize the program.
