Major critical users classes concerned • Two major classes : • Mission critical (private) such as Fire, Security, Health, Civil protection… • Non mission critical : • Administration critical (public and private) for Government agencies, Utilities…in order to decide, coordinate, inform... • Consumer critical (public) to allow the public (residential…) to make an emergency call, communicate, be informed... • Business critical (corporate) such as Companies, Operators…which are also concerned to maintain their work environment such as VPNs, data bases, ROBO, SOHO... • Using different communications means dedicated or commercial, with different EC policies,different services.…and who need to inter work Walter LEGRAND- EDSN Presentation
Emergency communications types • Communications types in case of emergency: • 1 Mission critical communications ‘day to day’ or ‘emergency’, or ‘disaster’ • Local: on site users (Fire, Security, Medical…) • Remote: Call centers (112…), operational/tactical… Computer Aided Dispatches (CAD), Control centers (GIS, AVL…) users • 2 Utilities (electricity, gas…) communications • 3 Agencies(local/regional/central administration, government, meteorology, environmental…) communications • 4 Operators communications • 5Corporate business communications • 6 Consumers communications • Using different network standards: PMR, PSTN, GSM, WLAN... Walter LEGRAND- EDSN Presentation
Mission critical communications • Use of a separate ( operated or not ) private, fixed and mobile, voice and data digital network (TETRA, APCO25, TETRAPOL as defined in ITU report M 2014) • High quality voice and data, end to end secured, fast set up, high traffic on a small area, operational whatever conditions, redundant nodes... • With specific features used like fast call set up,Security, Group call, Emergency call, a full set of specific Services … • Direct ModeDMO • With on site coverage, possibly ‘ad hoc’, anyway DMO • Composed of different sub systems like • Radio access, Core network, • Repeaters, Control centers, Call centers ... • Allowing inter workingbetweendifferent organizationson thesame or different networks Walter LEGRAND- EDSN Presentation
Business critical communications • Maintain business for Voice and Data • Disaster recovery • Geographical dispersion, but maintain service • Rely on public and private VPN networks, circuit and packet switched • Networks requirements for Corporate V+D continuity: • Network fast switching, data rerouting, redundancy, variable bandwidth, back up access • Mobile switches, IT Hubs... • VPN connectivity... • Remote access • Remote management Walter LEGRAND- EDSN Presentation
Consumers critical communications • Infrastructure for PSTN, ISDN, IP, Cables, GSM, TV… • Consumers need Voice and Data emergency communications, call back… • But also Agencies and Administrations, Corporate need of Communications resources for information, coordination and control (warning, reports, back up switching…) • Day to day: allow some resources as defined in ETS, GETS... • (But use of PMR could be easy as ‘under loaded’) • Emergency: generally public communications completely congested • Have to be restored, rerouted, controlled... Walter LEGRAND- EDSN Presentation
Consumer/Business and Mission critical connexity • ‘Routine’ situation: • PMR networks services for mission critical users • ETS (GETS, Pas…) limited set of PMR services on public networks for non mission critical users • Possible end to end Public to Private (to public) calls (Roaming…) • Emergency situation: differentiate on site mission critical users and remote users • On site connexity • Inter working of public/private networks to share information • Remote connexity • Have Points of connection between Private and Public networks through gateways, with guaranteed QoS, Security to allow: • Some back up/rerouting for Control and Call centers … users • Some administration, business, consumers priority/emergency calls • Some end to end Public to Private (to public) calls PMR Public ETS Walter LEGRAND- EDSN Presentation
ETSI SPAN 14 work • IPFN architecture as an open intelligent inter working platform • Work Item created in SPAN in June 2000 • Document EG 210 936 TC approved in December 2001 • users requirements and scenarios • architecture (new function identified as Core Profile Server...) • recommendations listed with liaison to Tiphon, SES, ECMA... • BOF meeting SPAN-TIPHON on IPFN in Washington in March 2001 • Recommendations taken in release 4 and 5 (Priority, Security…) of TIPHON with Public Private inter connection needs • Work item in SPAN for DEG /SPAN-140005 in January 2002 • Taking into consideration IEPS and IEMS • Focussed on core profile server • ENUM based work foreseen • EC Policies with multinational adaptation, (e-procedures) • ECcivil protection project EGERIS Walter LEGRAND- EDSN Presentation

Core profile server: a new area of standardization • Get Information on Networks (Interrogate Network Management …) • Get information on Users (Interrogate HLR …) • Authentication of authorized users • Ask for required QoS, Security... • Network Location of user • Choice of network according to status (ENUM…) • Value added functions as broadcast... Walter LEGRAND- EDSN Presentation
Other possible areas of standardization • Public - Private inter working gateway (TIPHON) • Some EC procedures and practices of civil protection…standardization (e procedures) • Emergency management • Translation function (Language…) • Mediation function (Different terminals…) • Converter function (Different formats…) • Inter networks Mobility • Push service according • to event, to procedure... • Value added services Walter LEGRAND- EDSN Presentation
Conclusion • Consumer and mission critical telecommunications core networks can offer complementarity and interoperability in routine and disaster situations, by being interconnected. • SPAN14has an architecture work ongoing with proposals of new functional sub systems, work is also linked to the EGERIS ECIST project • Classify situations, define commercial and dedicated networks roles, users types to clarify scenarios.
