Some comments on ITU-T work on NGN

Organisation of NGN studies in the ITU-T

• Study Group 13 (Study Group NGN) is one of
  thirteen study groups in the telecommunication
  standardisation sector of the ITU
• At the World Telecommunications Standardisation
  Assembly (October 2004) it was given the task to
  lead the standardisation work on Next Generation
  Networks
• This is being carried out on a project basis
  involving other study groups, other sectors of
  the ITU and other standardisation organisations,
  such as the IETF and ETSI

NGN Focus Group

• In order to accelerate the work on NGN
  standardisation a Focus Group was set up in June
  2004 under the auspices of Study Group 13
• Has been meeting every two / three months and the
  final meeting (the 9th) will be held at the end
  of 2005
• Its target has been to prepare Release 1
  specifications for NGN

Definition of Next Generation Network

• A Next Generation Network is a packet-based
  network able to provide telecommunication
  services, 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 offers unrestricted access by users to
  different service providers.
• It supports generalised mobility which will
  allow consistent and ubiquitous provision of
  services to users.

An NGN is characterised by the following
fundamental aspects

• Packet-based transfer
• Separation of control functions among bearer
  capabilities, call/session, and application/
  service
• Decoupling of service provision from network, and
  provision of open interfaces
• Support for a wide range of services,
  applications and mechanisms based on service
  building blocks (including real time/ streaming/
  non-real time services and multi-media services)
• Broadband capabilities with end-to-end QoS

• Interworking with legacy networks via open
  interfaces
• Generalised mobility
• Unrestricted access by users to different service
  providers
• A variety of identification schemes
• Unified service characteristics for the same
  service as perceived by the user
• Converged services between Fixed/Mobile
• Independence of service-related functions from
  underlying transport technologies
• Support of multiple last mile technologies
• Compliant with all regulatory requirements for
  example concerning emergency communications,
  security, privacy, lawful interception

Impacts on policy and regulatory aspects

• NGN provides for the separation of services and
  transport
• Policy and Regulation environments will be
  impacted by this
• Change from Vertical to Horizontal environment

8
Role of the ITU-T

• The ITU-T will not develop regulations for the
  NGN
• However with the wide participation of member
  states, operators, vendors and regulators the
  ITU-T does provide a forum for regulatory aspects
  to be considered in order that the necessary
  capabilities can be built into the standards
