(continuation of part of Q.1/2)
With the advent of IP-based networks, it will become increasingly important
to ensure that users of various voice-based and non-voice-based services,
particularly on the PSTN, ISDN and mobile networks, can communicate with other
users on other networks. Interworking of existing and new services and
capabilities will be ever important to satisfy customers' new and/or changing
requirements (e.g. QoS, terminal/personal mobility). In addition, increased
awareness of customers' needs by administrations and ROAs, and the continued
emergence of competition are likely to increase the pace of new service
development. It is especially important that mechanisms, including interworking
scenarios, be identified which may be of benefit to developing countries in
making the transition from legacy networks (for example, the telex network) and
the services that they support to more modern means of telecommunication,
possibly supported on IP-based networks, or other data networks.
The Question will deal with the issues detailed under Tasks below.
||Topics and rationale
||Target completion date
Maintenance of all existing service-related Recommendations
Rationale: This project reviews and revises, where and when appropriate, the
existing service-related ITU-T Recommendations, including international
telephone, international telecommunication charge card, international
freephone, international premium rate, international shared cost services,
ISDN, UPT, and mobility services, e.g. E.105, E.106, E.116, and F.110,
F.111, F.115, F.116.
Service and Operational aspects of numbering and related service
Rationale: It is important to ensure that users of
various voice-based and non-voice-based services, particularly on the PSTN,
ISDN and mobile networks, can communicate with other users on other networks
including IP based networks.
Changes in the provision of telecommunication services, including aspects
of international roaming across both terrestrial and satellite based mobile
networks may give rise to the need for new service requirements and
definitions for numbering naming and addressing resources.
This project will assess the impact of introduction of IP-based networks
(including NGN) and interworking with IP-based networks (including NGN) to
determine what new services, service features, and service principles for
interworking need to be defined to take advantage of this technology,
including matters related to:
- Requirements for international emergency preference scheme (IEPS)
and related facilitation by telecommunication for disaster relief (TDR)
on national level.
- Quality of service requirements.
- Security requirements.
Specifically in relation to NGN, there may be work within this Project
arising from the NGN issues.
Service and Operational Aspects for mobile services (terrestrial cellular
Rationale: Develop service requirements for the broadcast of
emergency messages to warn and inform the public over mobile services. The
project would take a long-term view to use whatever form of bearer is most
appropriate, which will change as technology develops. It will develop a
framework for harmonizing logical address space in different bearer services
over different service areas and across national boundaries. The focus
should be to facilitate multi-language warnings, cross-border roaming, and
to prevent spam.
Other projects as they are proposed and approved
significant amount of Q.3/2 work throughout a study period is the result of
new issues presented by Q.3/2 Collaborators. These issues typically resulted
in numerous new projects defined and approved during the previous study
Q.3/2 will continue to define, study, and resolve new issues through the
approval of additional projects.
