               Background

 A consultation process was initiated on
  NGN in Jan 2006 to deliberate on various
  issues.
 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

                    CN Division, TRAI           2
            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
      Academicians.

           TRAI Decision no 6.4

 This committee will handle at least the following
  issues

   NGN awareness building program

   Time table for NGN migration in the country

   Back ground paper to be used for consultation on

    interconnection and QoS issues by TRAI.

                   Present Status

 Based on the recommendations a group named
  Focus working Group on NGN was setup with in
  TRAI in May 2006 having representations from MN,
  FN, QoS, CN and Eco division to discuss NGN
  issues internally.
 Terms of the reference of the NGN – eCO was made
  and circulated to various organizations seeking the
  representations.
 NGN –eCO committee was formed in June 2006
  having representations from 19 organization. There
  are total 30 members INCLUDING 5 members from
  TRAI.

 Scope of work
1) NGN awareness building programme
      Closely interact with international bodies like ITU, ETSI, 3GPP2,
       Regulators abroad etc. for obtaining latest information and
       knowledge related to NGN
      Organize awareness programmes to educate other stakeholders
       in the country and make them aware of latest trends in NGN and
       its capabilities.
2) Timetable for NGN migration in the country
      Prepare a detailed timetable for NGN migration in the country
      Provide an implementable, phased and business-driven
       roadmap/ action-plan for achieving this.

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.

          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
  advantage
 Fixed-mobile convergence,

               Advantages of NGN
NGN makes use of best of both the worlds (flexibility, efficiency
& Innovativeness of IP and QOS, Security, Reliability, Customer-
friendly features of proven PSTN
•Advantages for service providers
  Reduced CAPEX due to integrated and efficient IP-based
   technology (Packetized Network)
  Reduced OPEX due to transmission cost saving, less power
   consumption, less space requirement, less O&M costs
  Ability to offer increased range of services
  More flexibility increasing market penetration by offering personal
   service customization and management
  Single network layer for management
  There is no need for separate voice and data networks

   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.

                   Way forward
 It is proposed to setup three core sub groups to
  deliberate on various identified issues.
    Regulatory issues

    Interconnect issues

    Quality of Service (QoS) issues

 Core sub groups will have representations from various
  sector of Industry.
 They will submit their paper on identified issue in two
  month time.

             Way forward                    contd.


 Need to closely interact with international bodies like
  ITU, ETSI, 3GPP2, Regulators abroad etc. for
  obtaining latest information and knowledge related to
  NGN
 Need to organize awareness programmes to educate
  other stakeholders in the country and make them
  aware of latest trends in NGN and its capabilities
 Stakeholders can give their inputs to core group
  through e-Mail published on TRAI website for different
  core groups


                        CN Division, TRAI             32
    Time frame for launch of NGN
 Should some time frame be defined for launch of
  NGN
 Should we concentrate policies on end to end NGN
  or limit it to core to start with.
 What should be mile stones
