| ITU-T Study Group 2 Area of Responsibility (Study Period 1997 - 2000) |
 Responsible for studies
relating to:
- General
aspects of service definition related to telecommunication
services;
- PSTN
based, ISDN(s), mobile and UPT services, principles of their
interworking and relevant user quality of service (QoS);
- network
operations including routing, numbering, network management
and service quality of networks (traffic engineering, operational
performance and service measurements);
- human
factors;
- service
and operational aspects of fraud prevention.
Lead
Study Group on Service definition, Numbering, Routing and Global Mobility
- Study
Group 2 is the Lead Study Group for service definition (including all
types of services) for numbering and routing and for global
mobility.
Study Group 2 has a coordination role in studies on billing
information
(Phase one) and operational quality of service/network
performance.
- Study
Group 2 shall define and describe services including FPLMTS in
its area of responsibility from a user's point of view to
facilitate global
interconnection and interoperation and also ensure compatibility
with the
International Telecommunication Regulation and related
intergovernmental agreements. It should also recommend QOS for
each
service and interact with other Study Groups (e.g. SG 13) in this
respect
as required.
- Within
its area of responsibility Study Group 2 should define services
functionally on an end-to-end basis, deal with supplementary
services,
services facilitating access to basic services and with services
that are
supported by networks or by other services, such as telephone.
- Study
Group 2 should continue to study service policy aspects including
those that may arise in the operation and provision of transborder, global
and/or regional services, including those that offer both
carriage and
content components, taking due account of national sovereignty.
- Bureau,
document communication, directory and audiovisual/multimedia
services are studied, except in the mobile environment, by other Study
Groups (SG 7, SG 8, SG16) being responsible for
relevant technologies.
However, harmonization of service interworking and service operation
aspects is required.
- Study
Group 2 is responsible for studying, developing and
recommending general principles of numbering and routing for all
types
of network.
- The
Chairman of Study Group 2 (or, if needed the Chairman's delegated
representative) should provide technical advice to the Director
of the
TSB concerning general principles for numbering and routing and
the
effect on allocation of international codes.
- Study
Group 2 should provide the Director of the TSB with advice on
technical, functional and operational aspects in the assignment,
reassignment and/or reclamation of international numbering and
addressing resources in accordance with the relevant E- and F-Series
Recommendations taking into account the results of any ongoing
studies.
- Study
Group 2 recommend traffic engineering planning and dimensioning
guidance for the implementation and operation of all types of
networks
and network elements.
- Study
Group 2 recommend measures to be taken to assure operational
performance of all networks (including network management) in
order to
meet the in-service network performance and QOS.
- If
Study Group 2 identifies operating functions which need the support of
network capabilities, these functions should be defined and
described
on the basis of the description method and network architectural
principles as defined by SG13.
