PowerPoint PowerPoint Presentation Transcript

  • ETSI SPAN Public and Private networks complementarity in Emergency Telecommunications  [email_address] Emergency Telecommunications Workshop 26th-27th February 2002, ETSI, Sophia Antipolis - France
  • Presentation outline
    • Disaster global scenario, SPAN analysis
    • Major critical users classes
    • Emergency communications types
    • Mission critical communications
    • Business critical communications
    • Consumer critical communications
    • Consumer and Mission critical connexity
    • ETSI SPAN14 work
    • Core profile server
    • Possible areas of standardization
    • Conclusion
    • Abbreviations
  • Toulouse AZF disaster Day to day operations Emergency or public event Disaster
  • SCN IP PMR SAT 3GPP GW IPFN WLAN/ad hoc/DMO DMO... V+D disaster GW VPN Disaster - global scenario SPAN analysis
  • 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
  • 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...
  • 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
  • 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
  • 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...
  • 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
  • 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)
    • EC civil protection project EGERIS
  • Servers IPFN 3GPP Data Bases (GIS…) Information Centres Radio Access Corporate Intranet Administrations GPS Operators VPN IT Public safety Emergency services, Civil protection... Residential public AGENCIES GW PABX ROBO SOHO IP core RTCP IPFN
  • Core Profile server user ENUM+?
  • One possible Users scenario PC Tel 3GPP user2 Tel Core profile server PMR Control Center user1 internet ENUM TV, Radio Dispatch
  • 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...
  • 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
  • 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.
