| Title:
|
Service and operational aspects of telecommunications, including service definition
|
| Description:
|
1 Motivation
With the emergence of the requirements of future telecommunication/ICT architectures, capabilities, 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 PLMN, to be able to communicate with other users on other networks remains essential. Interworking of existing and future telecommunication/ICT architectures, capabilities, applications and services, including emergency services, and capabilities will remain important to satisfy customers' evolving requirements (e.g., QoS, terminal/personal mobility).
In addition, increased awareness of customer needs by administrations and ROAs, and the continued application of competition to future telecommunication/ICT architectures, capabilities, 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.
2 Question
The Question will deal with the issues detailed under Tasks below.
3 Tasks
Tasks include, but are not limited to:
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, and mobility services, e.g., ITU-T E.105, E.106, E.116, and F.110, F.111, F.115, F.116.
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, 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, 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 the introduction of future IP-based networks and interworking with current IP-based networks (including NGN) to include developments of future telecommunication/ICT architectures, capabilities, 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.
The task will also establish the principles of service provision by OTT applications, their operational requirements, capabilities, and impact on other services.
Service & operational aspects of Telecommunication services, ICTs and applications
This task will ensure a consistent approach to the study of the relationship between Telecommunication services, ICTs and applications irrespective of where such work is done in the sector. The existence of multiple activities and associated specifications is being undertaken without a consistent approach to ensure that there is no contradiction through overlap, and no negative impact on operational work driven by SG2.
Activities under this task will review how the interworking of telecommunication services, ICTs and applications as drafted by other ITU-T SGs to:
- understand the operational aspects;
- Identify potential issues and areas of inconsistency with current best practice; and
- if appropriate, seek to address issues that arise.
This work will be undertaken in co-operation with the other SGs in a manner that promotes good practice and efficiency in producing output in the sector.
Service and Operational Aspects for emergency service provision
Further develop service requirements for the provision of emergency services to warn and inform the public about future telecommunication/ICT architectures, capabilities, applications and services. The task will evolve current emergency related recommendations to ensure that future telecommunication/ICT architectures, capabilities, applications and services can be used in 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, applications and service areas and across national boundaries. The focus should be to facilitate multi-language warnings, cross-border roaming, and to prevent spam.
Service and operational aspects of interworking issues
To study the service and operational impacts that could emerge from the interworking between current and future telecommunication/ICT architectures, capabilities, applications and services. This would include ongoing studies to identify characteristics of traffic that would render impermissible, as well as initiating studies of future telecommunication/ICT architectures, capabilities, and applications to assess their potential impact on existing services. The findings will provide guidance to Administrations and operators.
This Question will continue to define, study, and resolve future issues through the approval of additional tasks. An up-to-date status of work under this Question is contained in the SG2 work programme: https://itu.int/ITU-T/workprog/wp_search.aspx?sp=18&q=3/2.
