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,Utilitiesin 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, Operatorswhich 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,differentservices.and who need to inter work

Emergency communications types
Communications types in case of emergency: 1 Mission criticalcommunications day to day or emergency, or
disaster
Local: on site users (Fire, Security, Medical)
Remote
: Call centers (112), operational/tactical ComputerAided 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...
8/2/2019 ETSI EADS Presentation
7/18Walter LEGRAND- EDSN Presentation7
Mission critical communications
Use of a separate ( operated or not ) private, fixed and mobile, voice
and data digital network (TETRA, APCO25, TETRAPOL as defined inITU report M 2014)
High quality voice and data, end to end secured, fast set up, hightraffic 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

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, backup access
Mobile switches, IT Hubs...
VPN connectivity...
Remote access
Remote management

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, coordinationand 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 communicationscompletely congested
Have to be restored, rerouted, controlled...

Consumer/Business and Mission criticalconnexity
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, consumerspriority/emergency calls
Some end to end Public to Private (to public) calls

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) ofTIPHON 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

Conclusion
Consumer and mission critical telecommunications corenetworks can offer complementarity and interoperability in routineand disaster situations, by being interconnected.
SPAN14has an architecture work ongoing with
proposals of new functional sub systems, work isalso linked to the EGERIS ECIST project
Classify situations, define commercial anddedicated networks roles, users types to clarify
scenarios.
