Network Profile
ITU/BDT Regional Seminar on BWA, Moscow, 26 - 29 November 2007 6
Next Generation Network (NGN)
A packet-based network able to provide telecommunication
services
Able to make use of multiple broadband, QoS-enabled
transport technologies
Service-related functions are independent from underlying
transport-related technologies
Enables unfettered access for users to networks and to
competing service providers and/or services of their
choice
Supports generalized mobility which will allow consistent
and ubiquitous provision of services to users
