摘要
随着三网融合的推进,将会给Vo IP带来广阔的发展空间。针对目前常用的Vo IP系统存在的网络开销高、呼叫接通率低、信令过于复杂等问题,在对SIP协议在P2P网络环境下实现Vo IP的关键技术进行认真分析的基础上,提出了基于SIP的P2P Vo IP。通过给出基于SIP的P2P Vo IP的基本体系结构,分析了该系统中对等点的发现、用户注册及离线、呼叫建立等功能的实现方法,最后提出了基于SIP的P2P Vo IP系统还应该考虑的一些问题。
With the progress in the convergence of the telecommunication,internet and broadcasting networks,Vo IP will be presented with broad space for development. However,existing Vo IP systems usually suffer from high network overhead,low call completing rate,complex signaling,etc. To solve these problems,this paper,based on a thorough analysis of key technologists involved in Vo IP using SIP protocol in the P2 P network scenario,proposed the SIP- based P2 P Vo IP system. By introducing the basic architecture of the SIP-based P2 P Vo IP system,this paper also analyzes the implementation of functions including peer discovery,user registration and getting offline and call establishment,and points out some questions that should be considered in this system.
