1. Interoperability between people, organisations, regions and equipment Middle East TETRA Conference Dubai May 2004 Risto Toikkanen Nokia 11.05.2004

2. Various dimensions of Interoperability -Global issues in Public Safety & Security Organisational interoperability –Between agencies/organisations –Between people Regional interoperability –Between regions –Across national borders Technical interoperability –Between equipment

3. Organisational dimension Hurdles Legislation and/or regulation Operating procedures & practices Information security Radio spectrum Incompatible equipment Organisational interoperability: “Capability for agencies to communicate with each other” –On a daily basis –In emergency situations

4. Inter-regional dimension Inter-regional interoperability: “Capability for peer agencies to communicate across borders” –Between regions –Across national borders –New dimension: cross-agency & cross border Hurdles Legislation and/or regulation Politics Operating procedures & practices Information security Radio spectrum Incompatible technologies/equipment In Europe the cross-border interoperability is high on the EU/Schengen agenda. In Europe the cross-border interoperability is high on the EU/Schengen agenda.

5. Technology dimension Technical interoperability: “Process to ensure that equipment from multiple vendors are compatible” –Problem-free operation –Wanted functionality –In practice it is about protocol conformance Hurdles Standardisation Standard conformance Verification and certification Competitive environment Customer preferences Backward compatibility

6. Organisational interoperability: solutions Operating procedures –Agreements –Training Dedicated radio channels –Common technical specification –Agreed procedures Radio spectrum harmonisation –In some form this is a must Technology harmonisation – standards –Necessary to gain radio compatibility Shared networks –By far the most efficient tool –Requires high-tech system to ensure privacy –Both operational benefit and cost benefit BEST RESULT

7. Regional interoperability: solutions 1. Political & organisational readiness 2A. Conventional technical measures Extra equipment like cellphones Extended coverage across border or repeaters Control room interconnect by wireline Radio swap between control rooms e.g. Belgium & France Radio swap between users 2B. Network interconnect TETRA Inter-System Interface (ISI) Three-country pilot Belgium – Germany – The Netherlands Cross-network PMR functionality, first time True cross-agency & cross-border opportunity

8. Three-Country Pilot (1) Agreement between the governments of Belgium, Germany and The Netherlands Based on the requirements of the Schengen Agreement on cooperation of police forces and customs across the national borders To pilot cross-border functionality with TETRA ISI To create operational scenarios

9. Three-Country Pilot (2) Phase 1 pilot testing completed in 2003 by use of pre-ISI solutions Operational scenarios built and tested in practice final report published at www.3countrypilot.com Phase 2 ongoing now with operational requirements specification for the TETRA ISI produced in 2004 Winner of Outstanding contribution to TETRA award in TWC 2003 please see www.3countrypilot.com

10. Solutions are deeply technical Decisions are done in early development phase Cross-technology interoperability Specific operating modes like analog FM radio channels TETRA Interoperability The TETRA Interoperability (IOP) concentrates on technical interoperability certification of multi-vendor TETRA equipment. Successful IOP certification is fundamental in creation of open multi-vendor market. Open multi-vendor market is fundamental for the success of TETRA - and it has happened Technical interoperability: solutions

11. Benefits of open multi-vendor market User benefits wide choice of compatible certified terminals specialised product for special needs continuous and genuine competition less dependency - lower risk of market disturbances Industry benefits wider market, bigger volumes more possibility to invest – faster product creation longer lifetime of market TETRA MoU Association runs the IOP certification process to guarantee open multi-vendor market

12. TETRA IOP Certification process STANDARDS MoU Operator/User Association Technical Forum Members’ Enquiry TIP SPECS TMO AI group DMO AI group ISI group (PEI group) approx 12 suppliers TEST PLANS MoU Certification Body ISCTI *) – Rome/Italy ACCEPTED into OPERATION (Also need CE mark or TA) CERTIFICATE *) Instituto Superiore delle Comunicazioni e tecnologie dell'Informazione

13. TETRA IOP deliverables TETRA Interoperability Profile (TIP) documents available to members –V + D Air Interface TIP’s Parts 1 to 17 are published or agreed –DMO TIP’s Parts 1 to 3 are published or agreed –TETRA ISI TIP’s Parts 1 to 6 are published TETRA Interoperability Test Plan documents available to members –V + D Air interface Test Plans Parts 1-5, 7, 9-11 are published and used in certification –DMO Test Plan Part 1 is published and used in certification Certification test sessions arranged at manufacturer’s premises to run the test cases specified in the Test Plans TETRA IOP Certificates are public documents and published at the TETRA MoU website –A process is ongoing to improve the layout of the certification document to be more easily readable Most customers today require their equipment supplier to provide IOP certificates on the features they purchase

15. Conclusions Organisational interoperability Best cooperation is achieved by a shared network Current TETRA technology allows privacy and sharing Not to forget the cost savings by sharing Regional interoperability Becoming more & more important TETRA ISI is the tool for network interconnect Technical interoperability TETRA created a true multi-vendor market Benefits to both users and industry TETRA IOP Certificate is the paper to ask for
