 A consultation process was initiated on
  NGN in Jan 2006 to deliberate on various
 Based on the feedback of stakeholders and
  deliberation on issues, TRAI issued certain
  recommendations in March 2006.
 One of the decisions was regarding setting
  up of a committee named NGN-eCO

            TRAI Decision no 6.4
 “….. There is a need for setting up joint consultative
  committee under the aegis of regulator involving
  industry to deliberate upon the various issues related to
  interconnection, QoS, Awareness building and
  migration time table for NGN. For this purpose, it is
  decided that
   An expert committee named NGN eCO will be
      constituted by TRAI co-opting experts from DOT,
      TEC, C-DOT, service providers, venders and

Overview of NGN

     CN Division, TRAI   8
     Definition of NGN (ETSI)

 NGN is a concept for defining and deploying
 networks, which due to their formal separation
 into different layers and planes and use of open
 interfaces, offers service providers and
 operators a platform which can evolve in a
 step-by-step manner to create, deploy and
 manage innovative services.

                     CN Division, TRAI          9
          What is NGN?
          (From Common man’s point of view)

 Next Generation Services – Converged (quad-play, voice, data,
    video, mobile)
   Next Generation Access – High speed (Broadband) IP based
    connectivity (ADSL,VDSL, Wi-Max, Cable TV, FTTH.
   Next Generation Transport – Ethernet, IP-MPLS
   Next Generation Architecture – Service oriented, layered
    (transport, control, application)
   Next Generation Mobile – 3G+
   Next Generation Internet – IPv6
   Next Generation Interconnect – Capacity and Quality based
   Next Generation Licensing – Unified

        Driving forces for NGNs

 Integration of network resulting in huge
  network cost savings
 Reduction in operational costs
 Reduced time to roll out new services
 Ease in offering new services (VoIP, IP-TV)
 Cost     savings    hence     competitiveness
 Fixed-mobile convergence,

   NGN Regulatory Challenges
As per ITU:-

“The move to NGNs represents an opportunity to
  establish in advance ground rules for ensuring the
  continued passage to effective competition and
  minimise damage during transition”.

  It is in contrast to the regulation of the legacy
  network, which are actually in place. That is why,
  NGN is different.
