The TETRA Interoperability Certification Process 哈尔德 Harald Ludwig Chairman TETRA Technical Forum TETRA Experience 2006 China 8 Nov 2006, Beijing 1
Content of Presentation Ø TETRA Technical Forum Ø What is Interoperability Ø Benefits of Open Multi-Vendor Market Ø The Interoperability Process Ø What is IOP Tested and Certified Ø Status of IOP Specifications and Certification Ø Next Steps - The Way Forward 2
Structure of the TETRA Mo. U Association Operator and Users Association (OUA) Technical Forum (TF) Security and Fraud Prevention Group (SFPG) Rail Forum 3
Technical Forum Ø Open to all Mo. U Members Ø 5 Meetings per Year Ø Website and Mailing List Ø Task: Management and Monitoring of the TETRA Interoperability Process Ø Top Priorities for 2006/2007: – Implementat New Certificate Formats – Encourage other (non-European) manufacturers to join the Interoperability Process 4
What is Interoperability (IOP) Ø IOP ensures, that TETRA equipment from one manufacturer is working with TETRA equipment from another manufacturer, and vice versa. Ø IOP Testing gives the confidentiality, that purchased equipment is interoperable. Ø IOP ensures, that TETRA is an Open Standard. Ø IOP enables Multi-Vendor market for TETRA 5
Benefits of open multi-vendor market Ø 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 Ø Industry benefits – wider market, bigger volumes – more possibility to invest – faster product creation – longer lifetime of market TETRA Mo. U Association runs the IOP certification process to guarantee open multi-vendor market! 6
How does the IOP Process work? Common Standard Define Rules for Implementation Practical Test of Equipment IOP Specification Process IOP Certification Process 7
IOP Specification Process Ø A formal process managed by the TETRA Association Technical Forum – Users to define Requirements and Priorities – Manufacurers to provide technical expertise 8
IOP Specification Process Operator User Association (OUA) Know How V+D Topics & Goals DMO Drafts ISI PEI Proposals Resolution Comments Members Enquiry TF Meeting Technical Forum Requirements TETRA IOP Profile TETRA IOP (TIP) Test Plan Comments Manufacturers 9
TETRA Products Request for Testing TETRA IOP Profile. TETRA (TIP) IOP Test Plan TEST SESSION Evaluation of Results Independent TETRA Certification Body Duration approx. 4 -5 month IOP Certification Process TETRA IOP Certificate 10
Independent TETRA Certification Body Ø ISCOM is the official type approval body of Italy Ø Testing is performed at the infrastructure manufacturers premises supervised by ISCOM Ø Test execution is traced and the test logs are used by ISCOM to check the compliance to IOP specs. Ø After careful analysis of the logs the certificates are issued and published on the TETRA Mo. U web-site Photo by ISCOM 11
Interfaces covered by TETRA IOP AI Base Station PEI LSI PSTN NMI ISDN Base Station ISDN PDN BSI TETRA Base Station Switch TETRA Network DMI AI: DMI: ISI: PEI: ISI Other TETRA Network Air Interface Direct Mode Interface Inter-System Interface Peripheral Equipment Interface 12
Interoperability Testing ØProtocol Stack Testing – mainly Layer 3 signalling – some parts of Layer 2 ØFrequency Independent Testing – IOP Certificate is valid for all frequencies ØIOP Testing does not cover: – Type Approval Testing – EMC Testing – Electrical Safety Testing – RF Conformance Testing 13
Status of IOP Documents (1) Ø Ø 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) Ø Lists of Specifications available at: www. tetramou. com Using TETRA Interoperability Ø Specifications are property of the TETRA Mo. U Association and available free of charge to TETRA Mo. U Association members. 14

Status of IOP Testing and Certification (1) Ø 12 Manufacturers participate in IOP Testing: – 8 companies have received TETRA infrastructure certificates for 9 systems – 9 companies have received TETRA terminal certificates in trunked mode – 6 companies have received TETRA terminal DMO certificates – 2 companies have received TETRA terminal DMO gateway certificates 16
Status of IOP Testing and Certification (2) Ø In total 176 IOP Certificates issued Ø Testing and Certification for Inter-System Interface (ISI) and Peripheral Equipment Interface (PEI) has not started yet Ø Certificates available for download: www. tetramou. com Using TETRA Interoperability 17
Interoperability in Practice Ø Almost all TETRA networks use a mix of terminals from different vendors Ø High innovation speed: – more than 30 new terminal models have been launched during the last 3 years. – terminals with GPS receivers and colour displays Ø An increasing number of application developers rely on the TIP specifications and the IOP process Ø Many Users and Operators ask for IOP Certificates when purchasing new equipment 18
The Way Forward Ø Continuing success of TETRA in Asia Ø Increasing number of manufacturers in Asia Ø from a European-Centric to a Global Activity Ø TETRA Mo. U would like to invite Asian companies to join the IOP testing process. Ø The first Technical Forum Meeting outside of Europe will be held in Asia in February 2007 19
