ITU Plenipotentiary ConferenceNovember 2006, Antalya, Turkey

• PP ’06 Top policy-making body of ITU; asked ITU, among others,• to strengthen its core competencies, esp. in

radiocommunications and standardization, in a rapidly changing ICT environment

• to enhance partnerships with private sector, regional organizations, NGOs, PSOs, …

• to promote initiatives relating to emergency communications

• In particular, ITU-T is asked to• Build confidence and security in the use of ICTs• Assist members in deploying NGN effectively• Highlight the contribution of ICTs to development• Review the International Telecommunication Regulations• Bridge the standardization gap

• TAP for texts with policy or regulatory impact• AAP for technical texts

• Work (mostly) done in Study Groups (13 of them)• Truly global• Consensus decisions• Flexible, fast and transparent procedures• Brand name• IPR Policy

ITU-T

ITU-T’s Focus Group Concepthttp://itu.int/ITU-T/focusgroups

• Create forum-like entities as an “arms-length” organization under an ITU-T Study Group or TSAG

• Work on a well-defined topic, scheduled for completion at a specific time

• Goal: Encourage participation of non-members and members of other organizations (forums)

• Focus Groups have substantial freedom to establish their own rules• Can keep own brand name and at the

same time benefit from ITU’s branding• Non-ITU members can participate

• Focus Groups can issue its own deliverables and can provide deliverables to its parent Study Group but cannot issue Recommendations by themselves

21ITU-T Overview

• From/In/To Cars Communication – Work on specifications for transmission characteristics for headsets and hands free terminals

• IPTV – Coordinating and promoting the development of global IPTV standards

• Security Baseline for Network Operators – Defining a security baseline so that operators can assess their network and information security posture in terms of available standards

• NGN Management – Providing a centralized approach regarding specification of NGN related fault, configuration, accounting, performance, and security management interfaces

• Open Communications Architecture Forum – Defining specifications for a set of components for a new carrier grade open platforms

ITU-T Recommendations

24ITU-T Overview

ITU-T

ITU-T Recommendations

•Developed by 13 Study Groups and TSAG divided into themed series:

• A-series covers the Organization of the Work of ITU-T and guidelines related to Recommendations

• Series D through Z cover specific subject areas, for example:

• the G-series covers Recommendations on “Transmission systems and media, digital systems and networks”

• The Y-series covers Recommendations on “Global information infrastructure, Internet protocol aspects and next-generation networks”

25ITU-T Overview

ITU-T

Approval of Recommendations

• Traditional Approval Process (TAP)For Recommendations subject to policy or regulatory implicationsInitiated by an SG or WP meeting and completed, for final approval, at the subsequent SG meeting (§9 Res.1)

• Alternative Approval Process (AAP)For Recommendations without policy or regulatory implicationsOnce the text is considered sufficiently mature, it is submitted for AAP by an SG or WP meeting (Rec. A.8)
