基于SIP的无线局域网络视频电话系统

System of the WLAN Video Phone System Based on SIP

未来的电信网络无论是固网还是移动网络都将整合成一个AllIP网络的架构。因此异构网络间的信息如何正确的传递变得尤为重要,SIP协议已成为其中的重要关键技术。目前在有线的因特网上,已有许多通信软件提供了语音服务,而本研究则以SIP为基础在无线局域网络上开发视频电话系统,并设计了客户端代理者接口程序与服务器系统,在无线局域网中实现了基于SIP技术的视频电话系统。

The future telecommunication network,both the fixed network and the mobile networks,will be integrated into the structure of All IP Network.Also,SIP has been seen a sresolution to the problem of signal transmission between different types of network.Currently there are many software provid ingadequate voice services,and this particular study is intending to understand WLAN based on the application of SIP video phone.
