TISPAN IMS标准化进展

Standardization Status of TISPAN IMS

基于IMS的网络架构支持固定网络接入需求和未来网络的各种业务需求,有利于实现未来固定、移动网络在核心业务控制层的共享和融合,并提供对高层多种业务的支持,已经成为下一代网络的发展方向。本文介绍了TIS PANIMS的网络框架和功能结构,分析了TIS PANPSTN/ISDN仿真子系统的功能和接口,并对TIS PANIMS的功能结构进行了扩展。

Network architecture based on IMS can fulfill the access requirement of fixed network and the service requirement of future network, which plays a vital role in the Fixed Mobile Convergence （FMC） at core service control layer and supports multiple service of high layer, so IMS represents the development direction of future Next Generation Network （NGN）. This paper introduces the network framework and function architecture of TISPAN IMS, then analyzes the function and interface of TISPAN PSTN/ISDN Emulation Subsystem （PES）. In conclusion, we propose the extensible function architecture of TISPAN IMS.
