1、 International Telecommunication Union ITU-T TELECOMMUNICATION STANDARDIZATION SECTOR OF ITU WORLD TELECOMMUNICATION STANDARDIZATION ASSEMBLY Johannesburg, 21-30 October 2008 Resolution 2 ITU-T study group responsibility and mandates FOREWORD The International Telecommunication Union (ITU) is the Un
2、ited Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recomme

5、rg, 2008) The World Telecommunication Standardization Assembly (Johannesburg, 2008), recognizing the resolutions adopted by this assembly which contain many instructions and implications for the work of the relevant study groups, considering a) that the mandate for each study group needs to be clear
6、ly defined in order to avoid duplication of effort between study groups and to ensure the coherence of the overall work programme of the ITU Telecommunication Standardization Sector (ITU-T); b) that ITU-T has to evolve in order to stay relevant to the changing telecommunication environment and to it
7、s membership interests; c) that collocation of study group, working party or rapporteur group meetings could also be a means to avoid duplication of work and to improve efficiency of work; in practice, collocation enables: attendees participation in the work of more than one study group; reduction i
8、n the need for exchange of liaison statements between the study groups concerned; saving costs for ITU and for ITU members and other experts; d) that the World Telecommunication Standardization Assembly (WTSA), through Resolution 22, assigns authority to the Telecommunication Standardization Advisor
9、y Group (TSAG) in the interval between WTSAs to restructure and establish ITU-T study groups in response to changes in the telecommunication marketplace, noting that the study group structure, responsibilities and mandates agreed at WTSA may be modified in the interval between WTSAs, and that the cu
10、rrent study group structure, responsibility and mandates may be found on the ITU-T website or obtained from the Telecommunication Standardization Bureau (TSB), resolves 1 that the mandate of each study group, which it shall use as the basis for organizing its study programme, shall consist of: a gen
11、eral area of responsibility, as set out in Annex A, within which the study group may amend existing Recommendations, in collaboration with other groups, as appropriate; a set of Questions related to particular areas of study, which are compatible with the general area of responsibility and which sho
12、uld be results-oriented (refer to Section 7 of Resolution 1 of this assembly); 2 to encourage the study groups to consider collocation (e.g. of study group plenaries, working parties or rapporteur meetings) as a means to improve cooperation in some areas of work; the study groups involved will need

40、the post-2008 study Questions in accordance with the proposed structure and general areas of responsibility. The points of guidance are intended to clarify, where appropriate, interaction between study groups in certain areas of common responsibility and are not intended to provide a comprehensive l
41、ist of such responsibilities. B.2 This annex will be reviewed by TSAG as necessary to facilitate interaction between study groups, to minimize duplication of effort and to harmonize the overall ITU-T work programme. Study Group 2 Study Group 2 is the lead study group for service definition (includin
42、g all types of mobile services) and for numbering and routing. Study Group 2 has a responsibility for creating principles of service and operational requirements, including billing and operational quality of service/network performance. Service principles and operational requirements must be develop
43、ed for current and evolving technologies. Study Group 2 shall define and describe services from a users point of view to facilitate global interconnection and interoperation and, to the extent practicable, ensure compatibility with the International Telecommunication Regulations and related intergov
44、ernmental agreements. 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 taking due account of national sovereignty. Study Group 2 is responsible for studying, developing and reco
45、mmending general principles of numbering and routing for all types of network. The chairman of Study Group 2 (or, if necessary, the chairmans delegated representative), in consultation with Study Group 2s membership, should provide technical advice to the Director of TSB concerning general principle
46、s for numbering and routing and the effect on allocation of international codes. Study Group 2 should provide the Director of TSB with advice on technical, functional and operational aspects in the assignment, reassignment and/or reclamation of international numbering and addressing resources in acc
47、ordance with the relevant E- and F-series Recommendations, taking into account the results of any ongoing studies. Study Group 2 should recommend measures to be taken to assure operational performance of all networks (including network management) in order to meet the in-service network performance
48、and QoS. As the lead study group on telecommunication management, Study Group 2 also has the responsibility for the development and maintenance of a consistent ITU-T work plan, prepared with the cooperation of relevant ITU-T study groups, on activities associated with telecommunication management an
49、d with operations, administration and management (OAM). In particular, this work plan will focus on activities involving two types of interfaces: for fault, configuration, accounting, performance and security management (FCAPS) interfaces between network elements and management systems, and between management systems; and for transmission interfaces between network elements. 6 WTSA-08 Resolution 2 In support of market-acceptable FCAPS interface solutions, Study Group 2 studies will identify service provider and network operator re
