Question 3

​Service and operational aspects of telecommunications, including service definition

(Continuation of Question 3/2)

Motivation

With the emergence of the requirements of future telecommunication/ICT architectures, capabilities, technologies, applications and services and the continued development of future IP-based networks, providing constancy for users of various voice-based and non-voice-based services, particularly on the PSTN, ISDN and mobile networks, to be able to communicate with other users on other networks remains essential. Interworking of existing and future telecommunication/ICT architectures, capabilities, technologies, applications and services and capabilities will remain important to satisfy customers' future and/or changing requirements (e.g., QoS, terminal/personal mobility).
In addition, increased awareness of customers' needs by administrations and ROAs, and the continued application of competition to future telecommunication/ICT architectures, capabilities, technologies, applications and services are likely to increase the pace of future service development. It is especially important that mechanisms, including interworking scenarios, be identified that may be of benefit to developing countries in making the transition from legacy networks and the services that they support to more modern means of telecommunication/ICTs, possibly supported on current and future IP-based networks, or other fixed mobile or satellite networks.


Question

The Question will deal with the issues detailed under Tasks below.​

Tasks

Tasks include, but are not limited to:

1)  Maintenance of all existing service-related Recommendations

This task 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., ITU-T E.105, E.106, E.116, and F.110, F.111, F.115, F.116, F.85x.

2)  Service and operational aspects of numbering and related service definition issues

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 future telecommunication/ICT architectures, capabilities, technologies, applications and services including, but not limited to, current and future IP based networks.
Changes in the provision of telecommunication services, including aspects of international roaming across both terrestrial and satellite based architectures, capabilities, technologies, applications and services may give rise to the need for future service requirements and definitions for numbering, naming, addressing and identification resources.
This task will expand its assessment on the impact of introduction of future IP-based networks and interworking with current IP-based networks (including NGN) to include future developments of future telecommunication/ICT architectures, capabilities, technologies, applications and services requirements to determine what future services, service features, and service principles for interworking need to be defined to take advantage of technology developments.

3)  Service and Operational Aspects for emergency service provision

Further develop service requirements for the provision of emergency services to warn and inform the public over future telecommunication/ICT architectures, capabilities, technologies, applications and services. The task will evolve current emergency related recommendations to ensure that future telecommunication/ICT architectures, capabilities, technologies, applications and services are able to be used whatever medium is used. The task will study the provision of emergency service messaging, supporting emergency telecommunications provision over different current and future telecommunication/ICT architectures, capabilities, technologies, applications and service areas and across national boundaries. The focus should be to facilitate multi-language warnings, cross-border roaming, and to prevent spam.

4)  Service and operational aspects of interworking issues

To study the service and operational impacts of future telecommunication/ICT architectures, capabilities, technologies, applications and services that would emerge from interworking with existing telecommunication/ICT architectures, capabilities, technologies, applications and services. This would include continuing to study what characteristics of traffic can be identified that would enable traffic to be deemed as impermissible as well as initiating studies of future architectures, capabilities, technologies, applications and services to assess the exact nature of any impact upon services that may emerge with their implementation and provide guidance to Administrations and operators.
Q3/2 will continue to define, study, and resolve future issues through the approval of additional tasks.
