  1. Emergency Interfacing:Military and Civil Communications in Crisis Response Scenarios Dr Michael Street MIEE CEng CIS Division NATO Command, Control & Consultation Agency Michael.Street@nc3a.nato.int

  2. Crisis Response Scenarios • Crisis scenarios where a response is required • Natural disasters • Flooding (Czech Republic, Germany, Hungary, Italy, Norway, Poland, UK) • Earthquakes (Italy, Turkey, USA) • Hurricanes and Ice storms (Canada, USA) • Non-natural disasters • Transport crashes (Canada, Germany, Norway) • Fires (Germany, Netherlands) • Terrorism • Crisis Response Operations • ‘Traditional’ military CRO • Peace-keeping, peace-support, Operations Other than War etc

  3. Military and Civil Communications • In all previous disaster scenarios the military has been involved to support civil emergency services in a co-ordinated manner • In ‘traditional’ CRO, military works with NGOs, local services etc • Communications between military and civil emergency services are vital • Both have effective individual communications systems - the interface between is vital

  4. Effect of Disasters on Telecoms • Area affected • Natural - widespread • Man-made - limited • Communications Affected • Fixed line • Congestion and/or disruption • Radio • Congestion and/or disruption • Loss of power • Loss of infrastructure • Priority mechanisms utilised occasionally • From Euro-Atlantic Partnership Council, Civil Communications Planning Committee (N/EAPC U)

  5. Communications Infrastructure in crisis .. .. response operation Existing infrastructure is likely to be unusable and rapidly deployable communications will be required. Users may use remains of previous infrastructure as best they can.

  6. Emergency Telecoms: What’s needed • Communications system requirements: • Rapidly deployable • Easy to use • no time for operator training • Self supporting • Interconnected to other networks • High capacity • Congestion is a recurring problem in many emergency scenarios

  8. GSM & GPS • GSM data services support useful services for Emergency Operations • Position reporting • Status monitoring COTS GSM for Emergency Scenarios GSM Piconode • Standalone GSM infrastructure • BTS, BSC, MSC, NMS • Deployable - 20 kg, 0.6 m3 • Can be connected to other networks • GSM, PSTN, PABX • Satellite backhaul • Tactical Military • Used by UK in Kosovo GSM is useful, but no security Not just GSM, any digital mobile radio … like TETRA

  9. Military Position Reporting, Civil Bearer C2PC Common Operation Picture software operating over a TETRA network

  10. Military C2 software (C2PC) running over COTS (TETRA) network

  11. Military - Civil Interface • Interface between COTS TETRA network and military network • PC running Linux • NC3A developed interface software • Converts GPS to OTH/Gold format for MCIS

  12. TETRA - Military Services; Civil Standard • Developed for Public Safety & Security with C3 features • Group Communication • Direct Mode Operation (when no infrastructure) • Emergency facilities (call priorities & preemption) • Dispatching • TETRA services @ Combat Net Radio features • has many large, security conscious user groups • Large user groups -- COTS equipment

  13. Why COTS PCS ? “The times they are a changing” Bob Dylan • Military role has changed • Peace-keeping • Peace-support • Crisis response • OOW, Non-article 5 operations • Composition of forces has changed • increasingly multi-service, multi-national • Military budgets have changed

  14. NC3A PCS Study • Study all available Personal Communications Systems • terrestrial, satcom, COTS & GOTS • Evaluate for use against a detailed Crisis Response scenario • Match for suitability • different users e.g. military, policing, NGOs, VSOs • different applications e.g. speech, location, data, video • different tasks e.g. liaison, reconnaissance • different phases e.g. initial deployment to long-term peace support

  15. NC3A TETRA Evaluation SystemSHAPE - June ‘01

  16. NC3A Deployable Comms ModuleTETRA system installed inside(occasionally)

  17. Where is NC3A using? • NC3A, NL • SHAPE, BE • JWID 2001 • Poland • Strong Resolve • Baumholder, GE • Combined Endeavour 2002 • Banja Luka, BiH • SFOR/BRITFOR trial (97 Signal Sqdn, UK)

  18. ETSI Standards; NATO Exercises • NC3A TETRA system is • Mobile • Deployable • Easy to use • Combined Endeavour 2002 • Strong Resolve • Used to establish comms infrastructure for exercise • SFOR trial, Banja Luka • 2nd (National Communications) Signal Brigade, UK

  19. Military and Civil InterfacingPSTN, Public Safety Mobile Radioand Tactical Military Comms PSTN / TETRA / Autoko trials AUTOKO - German Army tactical comms Clear speech interoperability

  20. Secure Voice Communications • Military and many public safety users want secure speech services • In emergency scenarios public safety users may want privacy from media • Security against eavesdropping and disruption • Must consider and protect against emergencies where cause is deliberate • Unprotected communications leaves rescuers vulnerable

  21. TETRA Security and Fraud Prevention Group Guidance on implementing end-to-end encryption within ETSI Standards Prepared with public safety, commercial & military input • Contents • Introduction • Overview • Physical Realisation Issues • Use of Algorithms • Key Management • Interoperability • Threats • Specifications • Appendices • User profiles • Additional detail to be specified • Sample specification (IDEA) • Sample Test Data Courtesy of D Parkinson, BT Exact

  22. TETRA Standards SFPG Recommendation 02 End to End Encryption Algorithm Vocoder TETRACivil Technology, Military Security • Need to interface during the standards making process • User requirements • Technical spec Commercial or national (public safety or military) algorithm Vocoder (TETRA ACELP, AMR or MELPe)

  23. A Digression on CongestionAvoiding it: Military Vocoder vs Civil Vocoder Voice Coders COTS X = 3.6 kbps COTS Y = 4.56 kbps COTS X = 4.56 kbps MELPe = 2.4 kbps MELPe is NATO Stanag 4591 • Congestion is a problem in emergency scenarios • Choice of voice coder • Military is used to minimising throughput for low capacity channels • Same speech intelligibility, half the throughput • Interoperability • Frequency congestion and allocation Intelligibility (%) Male speaker Female speaker

  24. Security for other COTS PCSSummary of Trials with Early Commercial ‘Secure’ GSM Location Reliability Quality • Within NL 60-70% Good • Outside NL, Urban • Within country 90 % Good • International Poor • Rural 33 % Poor • GSM - PSTN 40 % Poor • But no NL-BE connectivity • Standard COTS services didn’t work as expected

  25. Military Secure GSM • Swedish/Norwegian Project • Integrated GSM / DECT unit • DECT via satellite • Encrypted Voice + Data • High grade • NATO and commercial versions • Reliable

  26. Summary • Long history of military forces working with public safety in emergencies • NATO is prepared for this role • e.g. NATO Civil Communications Planning Committee • Current events make military-public safety co-operation more likely and more important • Need effective, secure communications • Need commonality for quick and easy interfacing (interconnection and interoperability) • requires planning from the start • involvement by all in requirements definition and standards process
