Next Generation Network (NGN)

   Next-generation network (NGN) is a term used to describe key architectural evolutions in telecommunication core and access networks. The general idea behind the NGN is that one network transports all information and services (voice, data, and all sorts of media such as video) by encapsulating these into packets, similar to those used on the Internet. 

NGNs are commonly built around the Internet Protocol, and therefore the term all IP is also sometimes used to describe the transformation toward NGN. 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 and real-time, multi-media communications and it is high-speed access and transport for any medium, anytime, anywhere, and in any volume.
