  1. The TETRA Interoperability Certification Process 哈尔德 Harald Ludwig Chairman TETRA Technical Forum TETRA Experience 2006 China 8 Nov 2006, Beijing

  2. Content of Presentation • TETRA Technical Forum • What is Interoperability • Benefits of Open Multi-Vendor Market • The Interoperability Process • What is IOP Tested and Certified • Status of IOP Specifications and Certification • Next Steps - The Way Forward

  3. Structure of the TETRA MoU Association Operator and UsersAssociation (OUA) TETRA MoU Association Technical Forum (TF) Security and FraudPrevention Group (SFPG) Rail Forum

  4. Technical Forum • Open to all MoU Members • 5 Meetings per Year • Website and Mailing List • Task: Management and Monitoring of theTETRA Interoperability Process • Top Priorities for 2006/2007: • Implementat New Certificate Formats • Encourage other (non-European) manufacturers to join the Interoperability Process

  5. What is Interoperability (IOP) • IOP ensures, that TETRA equipment from one manufacturer is working with TETRA equipment from another manufacturer, and vice versa. • IOP Testing gives the confidentiality,that purchased equipment is interoperable. • IOP ensures, that TETRA is an Open Standard. • IOP enables Multi-Vendormarket for TETRA

  6. Benefits of open multi-vendor market • User benefits • wide choice of compatible certified terminals • specialised products for special needs • continuous and fast product innovation • continuous and genuine competition, hence lower prices • 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!

  7. Common Standard How does the IOP Process work? Define Rules Practical Test for Implementation of Equipment IOPSpecification Process IOPCertification Process

  8. IOP Specification Process • A formal process managed by the TETRA Association Technical Forum • Users to define Requirements and Priorities • Manufacurers to provide technical expertise

  9. V+D DMO ISI PEI IOP Specification Process Operator User Association (OUA) Requirements Comments TETRA IOP Profile (TIP) Topics & Goals Drafts TETRA IOP Test Plan TF Meeting Members Enquiry Resolution Technical Forum Know How Proposals Comments Manufacturers

  10. Duration approx. 4-5 month IOP Certification Process TETRA Products Independent TETRACertificationBody Request for Testing TETRA IOP Profile (TIP) TEST SESSION TETRA IOP Test Plan Evaluationof Results TETRA IOP Certificate

  11. Independent TETRA Certification Body • ISCOM is the official type approval body of Italy • Testing is performed at the infra-structure manufacturers premisessupervised by ISCOM • Test execution is traced and the test logs are used by ISCOM to check the compliance to IOP specs. • After careful analysis of the logs the certificates are issued and published on the TETRA MoU web-site Photo by ISCOM

  12. AI PSTN Base Station ISDN Base Station PDN PEI BSI Base Station Other TETRA Network DMI Interfaces covered by TETRA IOP PSTN LSI NMI ISDN PDN TETRASwitch ISI TETRA Network AI: Air Interface DMI: Direct Mode Interface ISI: Inter-System Interface PEI: Peripheral Equipment Interface

  13. Protocol Stack Testing mainly Layer 3 signalling some parts of Layer 2 Frequency Independent Testing IOP Certificate is valid for all frequencies IOP Testing does not cover: Type Approval Testing EMC Testing Electrical Safety Testing RF Conformance Testing Interoperability Testing

  14. Status of IOP Documents (1) • Air Interface: 18 TIPs and 13 Test Plans • Direct Mode: 5 TIPs and 4 Test Plans • Inter-System Interface: 7 TIPs and 3 Test Plans • Peripheral Equipment Interface: 1 TIP (Draft) • Lists of Specifications available at:www.tetramou.com Using TETRA  Interoperability • Specifications are property of the TETRA MoU Association and available free of charge to TETRA MoU Association members.

  15. Air Interface V+D Functionality Part 1: Core Part 2: Short Data Service Part 3: Dynamic Group Number Assignment Part 4: Authentication Part 5: Packet Data (incl. Multi-Slot) Part 6: Air Interface Migration Part 7: Fleet Specific Short Number Part 8: RF Loop-Back Testing Part 9: Ambience Listening Part 10: End-to-End Encryption Part 11: Air Interface Encryption Part 12: Service Interaction Part 13: Enable/Disable Part 14: TETRA Key Distribution Part 15: Call Authorised by Dispatcher Part 16: Air-to-Ground Part 17: Radio User Assignment Part 18: Circuit Mode Data DMO Functionality  Part 1: Core Part 2: Gateway Part 3: Repeater Type 1 Part 4: End-to-End Encryption Part 5: Air Interface Encryption ISI Functionality Part 1: Mobility Management Part 2: Individual Call Part 3: Short Data Service Part 4: Lower Layers Part 5-1: Circuit Mode Speech Format Part 5-2: Packet Mode Speech Format Part 6: Group Call PEI Functionality  Part 1: Core Status of IOP Documents (2)

  16. Status of IOP Testing and Certification (1) • 12 Manufacturers participate in IOP Testing: • 8 companies have received TETRA infrastructure certificates for 9 systems • 9 companies have received TETRAterminal certificates in trunked mode • 6 companies have received TETRA terminal DMO certificates • 2 companies have received TETRAterminal DMO gateway certificates

  17. Status of IOP Testing and Certification (2) • In total 176 IOP Certificates issued • Testing and Certification for Inter-System Interface (ISI) and Peripheral Equipment Interface (PEI) has not started yet • Certificates available for download:www.tetramou.comUsing TETRA Interoperability

  18. Interoperability in Practice • Almost all TETRA networks use a mix of terminals from different vendors • High innovation speed: • more than 30 new terminal models have been launched during the last 3 years. • terminals with GPS receivers and colour displays • An increasing number of application developers rely on the TIP specifications and the IOP process • Many Users and Operators ask for IOP Certificates when purchasing new equipment

  19. The Way Forward • Continuing success of TETRA in Asia • Increasing number of manufacturersin Asia • from a European-Centric to a Global Activity • TETRA MoU would like to invite Asian companies to join the IOP testing process. • The first Technical Forum Meeting outside of Europe will be held in Asia in February 2007
