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
– 5 Corporate business communications
– 6 Consumers communications
• Using different network standards: PMR, PSTN,
GSM, WLAN...
6
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 Mode DMO
• 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 working between different organizations on the
same or different networks
7
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
8
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...
9
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
PMR
– 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
Public ETS
priority/emergency calls
– Some end to end Public to Private (to public) calls

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

Control Center
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...
15
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
16
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.
• SPAN 14 has an architecture work ongoing with
proposals of new functional sub systems, work is
also linked to the EGERIS EC IST project
• Classify situations, define commercial and
dedicated networks roles, users types to clarify
scenarios.
