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...


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

Public ETS



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

ENUM based work foreseen

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.
