| 摘 要： | IMS是NGN的IP多媒体业务部件,是为3G的IMS域用户和固定宽带用户提供融合业务的统一网络.对于固定宽带用户,软交换是IMS的一种实现.PSTN/窄带软交换与统一IMS分属不同的网络并且将长期并存.为宽带终端提供业务的软交换设备必然要成为统一IMS的一部分,覆盖固定宽带终端的网络将向统一IMS演进.本文还介绍了呈现、即时消息等业务服务器的组网方式以及基于IMS的语音融合业务的实现方案.

| Abstract: | IMS is a unique network which can provide converged services to both the 3G IMS subseribers and fixed SIP terminals. For the latter, softswiteh is an implementation of IMS. PSTN/narrow-band softswiteh network is independent from the unique IMS while they coexist in a long term. Broad-band softswiteh network is believed to become part of IMS and ultimately evolve to IMS. This paper also introduces the implementation of IMS services, such as presence/instant message and converged voice service. |
