ITU-T Study Groups (Study Period 2005-2008)

Lead Study Group Activities

Standardization work is carried out by the technical Study Groups (SGs) in which representatives of the ITU-T membership develop Recommendations (standards) for the various fields of international telecommunications.

The SGs drive their work primarily in the form of study Questions. Each of these addresses technical studies in a particular area of telecommunication standardization. Each SG has a SG Chairman and a number of vice-chairmen appointed by the World Telecommunication Standardization Assembly (WTSA).

Lead Study Group for service definition, numbering and routing
Lead Study Group for Telecommunication for Disaster Relief/Early Warning

Areas of study

SG 2 is responsible for studies relating to:

principles of service provision, definition and operational requirements of service emulation;
numbering, naming, addressing requirements and resource assignment including criteria and procedures for reservation and assignment;
routing and interworking requirements;
human factors;
operational aspects of networks and associated performance requirements including network traffic management, quality of service (traffic engineering, operational performance and service measurements);
operational aspects of interworking between traditional telecommunication networks and evolving networks;
evaluation of feedback from operators, manufacturing companies and users on different aspects of network operation.

Study Group 3

Tariff and accounting principles including related telecommunication economic and policy issues

Areas of study

SG 3 is responsible for studies relating to tariff and accounting principles for international telecommunication services and study of related telecommunication economic and policy issues. To this end, Study Group 3 shall in particular foster collaboration among its members with a view to the establishment of rates at levels as low as possible consistent with an efficient service and taking into account the necessity for maintaining independent financial administration of telecommunication on a sound basis.

Study Group 4

Telecommunication management

Lead Study Group on Telecommunication Management

Areas of study

SG 4 is responsible for studies regarding the management of telecommunication services, networks, and equipment, including support for next generation networks (NGN) and the application and evolution of the telecommunication management network (TMN) framework.

Additionally, it is responsible for other telecommunication management studies relating to designations, transport-related operations procedures, and test and measurement techniques and instrumentation.

Study Group 5

Protection against electromagnetic environment effects

Areas of study

SG 5 is responsible for studies relating to protection of telecommunication networks and equipment from interference and lightning.

Also responsible for studies related to electromagnetic compatibility (EMC), to safety and to health effects connected with electromagnetic fields produced by telecommunication installations and devices, including cellular phones.

Study Group 6

Outside Plant and related indoor installations

Areas of study

SG 6 is responsible for studies relating to outside plant such as the construction, installation, jointing, terminating, protection from corrosion and others forms of damage from environment impact, except electromagnetic processes, of all types of cable for public telecommunications and associated structures.

Study Group 9

Integrated broadband cable networks and television and sound transmission

Lead Study Group on integrated broadband cable and television networks

Areas of study

SG 9 is responsible for studies relating to:

Use of cable and hybrid networks, primarily designed for television and sound programme delivery to the home, as integrated broadband networks to also carry voice or other time critical services, video on demand, interactive services, etc.
Use of telecommunication systems for contribution, primary distribution and secondary distribution of television, sound programmes and similar data services.

Study Group 11

Signalling requirements and protocols

Lead Study Group on Signalling and Protocols
Lead Study Group on Intelligent Networks

Areas of study

SG 11 is responsible for studies relating to signalling requirements and protocols for Internet protocol (IP) related functions, some mobility related functions, multimedia functions for networks including convergence toward NGN, and enhancements to existing Recommendations on access and internetwork signalling protocols of BICC, ATM, N-ISDN and PSTN.

Study Group 12

Performance and quality of service

Lead Study Group on Quality of Service and performance

Areas of study

SG 12 is responsible for Recommendations on the end-to-end transmission performance of terminals and networks, in relation to the perceived quality and acceptance by users of text, data, speech, and multi-media applications.

Although this work includes the related transmission implications of all networks and all telecommunication terminals, a special focus is given to IP QoS, interoperability and implications for NGN, and also includes work on performance and resource management.

Study Group 13

Next Generation Networks

Lead study group for NGN and satellite matters

Areas of study

SG 13 is responsible for studies relating to the architecture, evolution and convergence of next generation networks including frameworks and functional architectures, signalling requirements for NGN, NGN project management coordination across study groups and release planning, implementation scenarios and deployment models, network and service capabilities, interoperability, impact of IPv6, NGN mobility and network convergence and public data network aspects.

Study Group 15

Optical and other transport network infrastructures

Areas of study

SG 15 is the focal point in ITU-T for the development of standards on optical and other transport network infrastructures, systems, equipment, optical fibres, and the corresponding control plane technologies to enable the evolution toward intelligent transport networks. This encompasses the development of related standards for the customer premises, access, metropolitan and long haul sections of communication networks.

Study Group 16

Multimedia terminals, systems and applications

Lead Study Group on multimedia terminals, systems and applications
Lead Study Group on ubiquitous applications (“e-everything”, such as e-health and e-business)

Areas of study

SG 16 is responsible for studies relating to multimedia service capabilities, and application capabilities (including those supported for NGN). This encompasses multimedia terminals, systems (e.g., network signal processing equipment, multipoint conference units, gateways, gatekeepers, modems, and facsimile), protocols and signal processing (media coding).

Study Group 17

Security, languages and telecommunication software

Areas of study

SG 17 is responsible for studies relating to security, the application of open system communications including networking and directory, and for technical languages, the method for their usage and other issues related to the software aspects of telecommunication systems.

Study Group 19

Mobile Telecommunication Networks

Lead study group on mobile telecommunication networks and for mobility

Areas of study

SG 19 is responsible for studies relating to network aspects of mobile telecommunications networks, including International Mobile Telecommunications 2000 (IMT-2000) and beyond, wireless Internet, convergence of mobile and fixed networks, mobility management, mobile multimedia functions, internetworking, interoperability and enhancements to existing ITU-T Recommendations on IMT-2000.

TSAG

Telecommunication Standardization Advisory Group

TSAG reviews priorities, programmes, operations, financial matters and strategies for the Sector, follows up on the accomplishment of the work programme, restructures and establishes ITU-T Study Groups, provides guidelines to the Study Groups, advises the Director of TSB, elaborates A-series Recommendations on organization and working procedures.
