3. 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
11/19/2018

4. Disasters happen any place, any time, unexpectedly
Why ETS
Telecommunications resources often experience severe stress with damaged infrastructure and very high traffic loads
Serious
Disasters happen any place, any time, unexpectedly
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

7. 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
11/19/2018

8. 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: , instant messaging, Web access, wireless access, distributed database, interactive audio and video, multicast, remote dbase queries, etc. – Enhanced capabilities

9. CDC-2001 Extract
The Second Tampere Conference on Disaster Communications, Tampere, Finland, 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
11/19/2018

10. ETS are collectively being referred to as
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
11/19/2018

11. The Way Ahead
Establish family of international ETS standards for global interoperability of emergency communications
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
11/19/2018

12. 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
11/19/2018

13. Objectives of ETS Selection of multimedia & telephony services
Rapid authentication of authorized ETS users
Security protection of 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
11/19/2018

14. Fulfillment
Draw upon existing standards with minimal changes or additions, if necessary to meet objectives.
Do not impede or interfere with natural functions and operations of basic Internet infrastructure.
Support preferential treatment of emergency calls in IP-telephony service.
new applications– instant messaging & presence, registration of missing/survivors (IAA), broadcast video.

17. 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

19. Security Considerations
Authentication
Allow access to only authorized ETS users
Intrusion
Prevent interference with flow and processing of ETS traffic
11/19/2018

20. Authentication
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).
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
