因为要评副高职称了,必须交篇5000字的论文,可是本人才疏学浅,又在基层运营商做技术管理,实在没有什么拿手的,放眼观望:现在也就NGN什么的吃香,可是自己是一知半解,想乘收集资料时好好学习,诚恳望高手能多赐教啊:
1,NGN的定义:这个INCLUDING是否说NGN可以提供电信以外的业务?TELECOMMUNICATION又是什么概念呢?
               这个UNRESTRICTED指的服务提供商,包括接入商吗?又如何UNRESTRICTED呀?亚星游戏官网-yaxin222

Definition of Next Generation Network
A Next Generation Network (NGN) is a packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies. It offers unrestricted access by users to different service providers. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.
