A Next Generation Network (NGN) is a packet-based
network able to provide services including
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 offers unrestricted access by users to
different service providers. It supports generalized
mobility which will allow consistent and ubiquitous
provision of services to users.

• 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)
• Broadband capabilities with end-to-end QoS
and transparency
• Interworking with legacy networks via open

• Generalized mobility
• Unrestricted access by users to different
service providers
• A variety of identification schemes which can
be resolved to IP addresses for the purposes of
routing in IP networks
• 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
• Compliant with all Regulatory requirements, for

The separation of services from the network
is a key cornerstone of the NGN, i.e., two
distinct blocks of functionality

• ITU’s NGN (e.g., IP) related standards are
being developed in cooperation with other
standards development organizations (SDOs)
to add to ITU’s long-term expertise in
telecommunications to the process of
developing new Internet standards and the
evolution of old ones.
• A number of ITU-T IP-related standardization
activities are done in cooperation with the
Internet Engineering Task Force (IETF). A
common interest mapping of IETF Working
Groups to ITU-T Study Groups is available on
the ITU-T Study Group 13 website.
• Create ITU-T Focus Group on NGN
• ITU-T also conducts seminars and
workshops within its domains of
competence: e.g.,

Declaration of Principles: e.g.,
37. Spam and cyber-security should be dealt with at appropriate
national and international levels.
48. The international management of the Internet should be
multilateral, transparent and democratic, with the full
involvement of governments, the private sector, civil society
and international organizations.
49. The management of the Internet encompasses both technical
and public policy issues and should involve all stakeholders and
relevant intergovernmental and international organizations.
50. International Internet governance issues should be addressed in
a coordinated manner.
64. The core competences of the International Telecommunication
Union (ITU) in the fields of ICTs—assistance in bridging the
digital divide, international and regional cooperation, radio
spectrum management, standards development and the
dissemination of information—are of crucial importance for
building the Information Society.
International
Plan of Action: e.g.,
9.j) Optimize connectivity among major information networks by
encouraging the creation and development of regional ICT
backbones and Internet exchange points, to reduce
interconnection costs and broaden network access.
9.k) Develop strategies for increasing affordable global
connectivity, thereby facilitating improved access.
13.c) Governments are invited to:
i) facilitate the establishment of national and regional
Internet Exchange Centres;
ii) manage or supervise, as appropriate, their respective
country code top-level domain name (ccTLD);
iii) promote awareness of the Internet.
13.d) In cooperation with the relevant stakeholders, promote
regional root servers and the use of internationalized
domain names in order to overcome barriers to access.
