浅谈NGN的体系架构

Discussion on NGN Framework

目前,下一代网络(NGN)的体系架构已经成为各国际标准组织的研究热点。ITU和ETSI都认为IMS的体系架构具有与接入无关、能够提供多种业务的特点,是NGN的核心结构,并在IMS体系的基础上,进一步提出了支持固定和移动综合接入的NGN体系架构。

At present, framework of NGN has become study hotspots of international standard organizations. ITU and ETSI presume that IMS framework is core structure of NGN and is irrelevant to access while providing various services. Based on IMS framework, it brings forward NGN framework supporting fixed and mobile access.
