Summary of Study Group replies
Replies to the draft ITU-T Action Plan for Standardization on Telecommunications for Disaster Relief and Early Warning (TDR/EW) were received by
TSAG from ITU-T Study Groups 9, 11, 12, 16, 17 and 19. Study Groups 2 and 6 did not meet since the last TSAG meeting in March 2005.
- ITU-T Study Group 9 has developed requirements for preferential telecommunications over IPCablecom networks and is developing specifications for preferential telecommunications over IPCablecom networks. Additionally, it will study if additional work is possible in this area.
- ITU-T Study Group 11 has developed BICC and ISUP support for IEPS priority mechanism defined in E.106 (2000) and has approved amendments that extend that support to the 2003 revision of E.106. Additionally, SG 11 intends include the support for TDR/EW in the signalling and control protocols required to support FGNGN requirements.
- ITU-T Study Group 12 reported that while it has no specific study items directly related to TDR/EW, it has substantial expertise in communication quality and would be pleased to provide advice as needed on its areas of expertise.
- ITU-T Study Group 13 has ongoing work on emergency telecommunication. A framework Recommendation on requirements and capabilities for network to support emergency telecommunications was approved during the last study period. There is additional work in progress to consider enabling emergency telecommunications in an NGN environment.
- ITU-T Study Group 15 has worked on Automatically Switched Optical Network (ASON) specifications, which by its own nature allow routing around major network failures and hence are directly applicable to TDR/EW scenarios by the definition of appropriate local policies for affected network elements (for example, by forcing existing calls to be dropped to free network resources then using call admission control to limit network access).
- ITU-T Study Group 16 has developed support for priority mechanisms over H.323 IP-based multimedia systems and started a new work item for message broadcast in H.323 that can be used for EW scenarios.
- ITU-T Study Group 17 identified three topics that relate to network security that are relevant to TDR/EW telecommunications scenarios: (a) Security Architecture and Secure Communications System; (b) Security Management; and (c) Security Incident/Event Handling. There are several Recommendations under SG 17 – existing and under development – that address these areas.
- ITU-T Study Group 19 addressed emergency services in a supplement for requirements for IMT-2000 networks and is preparing a chapter on the subject for the second edition of the Handbook on Deployment of IMT-2000 Systems.
- ITU-T Study Groups 9, 11, 12, 16, 17 and 19 are ready to cooperate with Study Group 2 within their areas of expertise, including in the organization of a future workshop on telecommunications standardization for TDR/EW.
