Agenda • Background • The Starting Line • Issues Under Consideration • Objectives and Focus of work • ETS Security Issues • Progress and Accomplishments • Time Line • Following the Action • Abbreviations
Emergency Communications Telecommunication services to support recovery operations Ensure effective communications to support recovery operations through severely congested and impaired resources during times of disaster – e.g. earth quakes, hurricanes, floods, volcano eruptions, terrorist attacks Authorized users – e.g. medical services, fire brigades, police, government and industry recovery teams
Telecommunications resources often experience severe stress with damaged infrastructure and very high traffic loads Initial recovery response teams need telecom support to enable organization and coordination of recovery resources immediately Response teams must depend on readily available public telecommunications resources – Internet, Cellular, POTS Why ETS Serious Disasters happen any place, any time, unexpectedly
FTS2001 INMARSAT DISN PSN WITH: PBX ACCESS AUTHORIZATION ENHANCED ROUTING PRIORITY TREATMENT Cellular/PCS Diplomatic Telecommunications Service (DTS) International FAX GETS The Government Emergency Telecommunications Service(GETS) GETS established to provide emergency access and specialized processing in local and long-distance telephone networks for authorized users GETS access is through a simple dialing plan and personal identification number (PIN)
GETS convergence NGN Tomorrow Fully integrated global services for NS/EP operations Yesterday PSTN/ISDN/PLMN Today Evolving Nets Transition with circuit/packet interworking Telecom Evolution FUTURE OF NS/EP COMMUNICATIONS
Approach Establish industry agreements collaboratively on telecommunications technology applications and implementation for next generation networks that will fulfill NS/EP operational requirements nationally, regionally, and internationally
Issues Being Addressed Fulfillment of requirement for priority communications among governmental, civil, and other essential users of public telecommunications services in crisis situations 1— Interfacing emergency communication process in existing telephony services with IP-based services during transition period when both services will interwork – PSTN/ISDN/PLMN transition 2— Adapting a broad range of emerging IP-based services to enhance ETS operations: Email, instant messaging, Web access, wireless access, distributed database, interactive audio and video, multicast, remote dbase queries, etc. – Enhanced capabilities
CDC-2001 Extract The Second Tampere Conference on Disaster Communications, Tampere, Finland, 28-30 May 2001 recognizing The vital role of telecommunications in international humanitarian assistence concerned That the magnitude, complexity, frequency and impact of disasters continue to increase at a dramatic rate, especially in the developing world invites The ITU to study ... Operational aspects of emergency telecommunications call prioritization
ETS IEPS – International Emergency Preference Scheme – ITU-T Recommendation E.106 IEMS – International Emergency Multimedia Service – ITU-T Draft Recommendation F.706 are collectively being referred to as Emergency Telecommunications Service (ETS) ETS can then be used in either an international or national context
Mapping ETS indicator codes at national gateways Maintaining foundation of existing national capabilities Expanding communications internationally on priority basis Facilitating orderly evolution to advancing technologies and enhanced capabilities Enabling new national capabilities to be established The Way Ahead Establish family of international ETS standards for global interoperability of emergency communications
Critical Issues Protocol mechanisms in IP-based networks to convey ETS indicator Procedures and processes for handling ETS traffic security measures for protection of ETS traffic Service Level Agreements Realization of ETS requirements in evolving networks should be accomplished by common mechanisms inherent in new basic infrastructure
Objectives of ETS • Selection of multimedia & telephony services • Rapid authentication of authorized ETS users • Security protectionof ETS traffic • Preferential access to telecom facilities • Preferential establishment of ETS communications • Preferential routing of emergency ETS traffic • Preferential use of operational resources for ETS • Preferential completion of ETS traffic • Optional pre-emption of non-emergency traffic • Allowable degradation of QoS for ETS traffic • Interchange of critical service management info
Do not impede or interfere with natural functions and operations of basic Internet infrastructure. Draw upon existing standards with minimal changes or additions, if necessary to meet objectives. new applications– instant messaging & presence, registration of missing/survivors (IAA), broadcast video. Support preferential treatment of emergency calls in IP-telephony service. Fulfillment

ITU-T Umbrella Question Qets/16 Emergency Telecommunications Service Development of emergency telecommunications systems concept and development of a requirements all aspects being addressed by many standards groups.
Qets/16 Cooperation • Close coordination & liaisons among: • ITU-T Study Groups – 2, 4, 9, 11, 12, 13, 16 , 17, SSG • ITU-R and ITU-D • UN Working Group on Emergency Telecommunications • Global Disaster Information Networks (GDIN) • ETSI – Projects MESA, TIPHON, 3GPP • Asia Pacific Telecommunity Standardization Expert Group on Public Safety and Disaster Relief Communications • User organizations – UN Red Cross others to be identified
Qets/16 Deliverables Cooperatively develop: • An emergency telecommunications systems concept – first draft May 2003 • An emergency telecom requirements Recommendation – first draft May 2003 • A systems framework showing how various components support emergency telecom requirements interwork – January 2004
Security Considerations Authentication Allow access to only authorized ETS users Intrusion Prevent interference with flow and processing of ETS traffic
Exiting ETS PSTN capabilities use a credit/calling card procedure to identified authorized users: • dial access number (10 digits), prompt • enter PIN (10 digits), prompt • enter called number (10 digits). Authentication Streamlined authentication using new technology to save valuable time for organizing and coordinating disaster recovery operations. Authentication passed along on multiple SP paths supporting communication instances
NO ENTRY Intrusion Protection of ETS traffic integrity • Spoofing • Denial of service • Changing content • Eavesdropping (for sensitive and confidential traffic)
QoS Parameter ITYs • Survivability • Reliability • Restorability • Durability • Availability • Understandability
Many Considerations • Technical — solutions being sought: • Operational • Policy • Legal • Regulatory • Industry networking standards that fulfill ETS requirements • Enhance ETS operations with value-added capabilities
Standards development is a process of consistency, persistence, patience Progress Established ETS Requirements in all major industry standards bodies Approved and advanced drafts of ETS framework Enthusiastic industry support First drafts of ETS technical specifications
Time Line January 2001 — Identified initial work areas for technical focus and initial technical area for enhanced features December 2001 — ETS requirements adopted in work programs of ITU-T, IETF, ETSI, ANSI T1, and TIA March 2001 – December 2003 —Proactively provide technical contributions and participate in work of specific technical areas of industry standards activities Autumn 2002 First meaningful standards to be established and adopted by industry FY 2002 – 2004 Prototyping work to validate applications of newly agreed upon industry standards
