摘要
本文是基于软交换(SoftSwitch)技术的发展而提出的,从网络融合的角度分析了SIP和ISUP互通单元(IWU,即InterworkingUnit)的结构模型,着重介绍了IWU上实现SIP和ISUP互通的原则和机制,为实现PSTN向软交换网络的平滑过渡提供了可行的解决方案。
Based on the rapid development of technology on softswitch, the interworking unit architecture model about SIP and ISUP protocol are analysed from the point of view of the integrating network. The principle of realization Interworking Unit(IWU) and its mechanism are explained which provides an effective solution for the PSTN network to evolve into softswitch network smoothly.
