Next Generation Networks [ NGN ]

Definition :
As per ITU - T " A NGN is a packet based network able to provide 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 enables unfettered access for users to networks and to competing service providers and/or services of their cgoice.It supports generalised mobility which will allow consistent and ubiquitous provision of services to users."

The essence of NGN
>> An IP-based network
>> Service independent from transport
>> One network – many services
>> Traffic management (QoS)
>>  An NGN is divided into a core and an access network.

Description :
"Generalised mobility":
At present subscribers are enjoying terminal mobility where network
identification system is available in the form of SIM and the same is inserted in
the terminal. If user is having that terminal he will be mobile with the identity of
the SIM.
In NGN subscriber can have Generalised mobility. Here, each individual will
have its own network identity in the form of "SIPURL: xyz @ domain
name.com
". Users have to make registration from his devices against the given
URL. Registrar servers of the company will maintain bindings with URL and physical location of registered devices. Users can register for more than one
device at a time. With this subscribers need not to depend upon specific terminal.
They can login with any device enabled with required protocols (SIP) and call
will come to that device.
