摘要
目前大多数论及NGN网的论文都认为NGN的核心模块是软交换设备.但这样的结构不能解决NGN网中被叫路由选择和用户漫游的问题,本文提出了一个新的NGN结构,它的核心模块除了软交换设备外,还包括PNS.这样的网络结构能同时解决被叫路由选择问题和用户漫游的问题.
The current architecture of NGN only composed soft switch equipment in core module that cannot solve the problems of called routing selection and roaming. A new architecture of NGN has been proposed that can solve both problems of called routing selection and the roaming problem.
