  1. Structure and management of very large TETRA project Seppo Seitsonen, JP-Epstar Ltd. tel +358 9 682 6696, email Management of large TETRA project

  2. Introduction • Describtion on how a nationwide and shared professional mobile radio project has been succesfully managed in Finland • Conclusions are personal views of the authors and are not official views of Finland’s Ministry of Interior, or VIRVE Unit • Authors are JP-Epstar’s consultants, who have worked in the VIRVE project since early 1990s, and performed tasks such as • Identification of requirements • Costs analysis • Assistance in the procurement process i.e. RFQ preparation, evaluation of tenders, contract negotiations • Assistance in management of the implementation • Auditing network performance Management of large TETRA project

  3. JP-Epstar • Independent telecommunications consulting and engineering company • Subsidiary of Jaakko Pöyry Group • Extensive experience in network based telecom business and projects, such as professional mobile radio systems for authorities and industries •, Management of large TETRA project

  4. VIRVE Network today • Authority Network = “VIRVE” • 1200 Base stations • Nationwide coverage • 15 Switching centres • 200+ Dispatcher work stations • Capacity for 50 000 user/terminals • 22 000 users/terminals (2003), growing • Service is well accepted by users 1200 km Management of large TETRA project

  5. VIRVEuser groups, public authorities Defence Forces Ministry of Social Affairs and Health Ministry of the Interior • Peacetime security operations • Inter-authority co-operation • Operations in Normal Conditions • Preparations for emergency situations • Police • Rescue Services • Frontier Guard Ministry of Transport and Communications Ministry of the Environment • Civil Aviation Authority • Meteorological Institute • Navigation Administration • Telecommunications administr. • Road Administration • National Broadcasting Company Ministry of Justice • Accident Investigation Agency Customs Authority Ministry for Foreign Affairs Prime Minister’s Office Ministry of Trade and Industry Other User Groups Office of the President of the Republic • Nat. Emergency Supply Agency • National Food Administration • Safety Technology Authority • Population Register Center • Technical Research Center of Finland Management of large TETRA project

  6. Background of VIRVE-project Background • High number and dedicated emergency centers of police and rescue organisation were found inefficient and expensive • Separate and incompatible radio system of police and rescue caused several operational limitations Goals • Reduce number of emergency centers and make them common • Public safety organisation wanted to intensify their mutual cooperation • Ministries of Interior, Defence and Transport and Communications preferred a common radio communication system Management of large TETRA project

  7. Phases of VIRVE project • Feasibility Evaluation • Identification of user requirements, technology evaluation, the first cost estimations. • Procurement • Preparation of the requirements for the VIRVE network, decisions concerning the scope of procurement, tendering and evaluation of tenders. • Implementation • Implementation of the network, terminal distribution and network testing. • Early Operation • Operation during the implementation phase. • Regular Operation • Operation when the most of the network had been implemented. Management of large TETRA project

  8. Time schedule of VIRVE project Management of large TETRA project

  9. Phase 1: Feasibility study phase • Ministy of Transport and Communications (neutral party) set up a project team • Most essential system requirements were managed communication within and between organisations, group call, fast call set up, encryption • Common view: A professional mobile radio system was required, cellular services do not meet requirements • No single organisation could set up the network • Ministry provides the network (investment), users pay for service (operational cost), ”normal” budget structure, outsourcing of the network operation Management of large TETRA project

  10. Phase 2: Procurement phase • VIRVE project was moved to Ministry of Interior due to user organisations and easier budget allocations • A part time project team was not enough -> VIRVE Unit was established • Network tender: • Focus on network functionality and features for users • Technology not fixed • Operator tender: • Focus on implementation and operation of the network • Supplier information provided • Contracts and responsibilities (1997): VIRVE Unit, supplier, operator, users Management of large TETRA project

  11. Phase-3: Procurement phase, contracts and responsibilities • VIRVE Unit • Design parameters for the network: coverage in different areas, capacity, interconnection • Network supplier • Installation and commissioning of the first two switches and 120 base stations • Maintenance support, software support • Network operator • Site acquisition, radio-network planning, • Trunk network, interconnection planning • Installation and commissioning of rest of base stations and switches, and Dispatcher WSs • Maintenance and user support • User organisations • Procurement of terminals • Implementation of VIRVE service in their own operations • Integration of control-room applications with the VIRVE service Management of large TETRA project

  12. Phase-3: Procurement phase, conclusions • Much easier to obtain funding for the improvement of co-operation than for a new network • Funds for a full-time project organisation needed from beginning • With only two supplier candidates for each tender, real competition was maintained • Frame contracts signed with the supplier -> flexibility • Handling of terminals and user applications as separate projects made the network project simpler, less costly and easier to manage • Time pressuremeant that the contract for operator services had some inadequacies • Better contracts management if • Installation of the network and operation during the installation phase -> Two contracts for the installation period • Regular operation -> One contract at end of the installation phase (better knowledge) • TETRA systems were still prototypes -> extensive system testing was required Management of large TETRA project

  13. Phase-4: Installation and early operation • Installation • 5 phases according to yearly budget allocations • System testing in Helsinki area -> difficult to get sites • Base station rollout went smoothly • Need for Dispatcher WS turned out to be much less • System testing • Terminals from several manaufacturers were missing • Tests made by different user groups were not coordinated well enough • Management centre • 24h network management and user support was established (run by VIRVE operator) • Terminals • Distributor was selected through an open tender • Implementation of VIRVE service • Planning of work processes took a lot of time • Availability of terminals which fulfilled requirements was delayed -> waiting • Group call feature in large area was not available -> problems in daily operations Management of large TETRA project

  14. Phase-4: Installation and early operation, conclusions • Stronger coordination and guidance by VIRVE Unit could accelerate implementation of VIRVE service within user organisations • Today VIRVE network could be implemented in 3 years, instead of 5 years, cost savings as parallel systems are needed for shorter time • Users wanted to be sure that the service would meet their need before start using it, a quality audit of each part of the network might increase confidence • It is very important to arrange efficient handling of user fault reports, their analysis and provision of feedback -> increased confidence • Definition of usability of service is different for each user group -> implementation of the new services takes different amount of time in each organisation Management of large TETRA project

  15. Phase-5: Regular operation • Complete network • 1200 base stations by end of 2002 • Capacity up to 50.000 user terminals • Network wide group call feature and data services • Wide range of compatible terminals • Routine VIRVE operation • Normal network maintenance, customer service, network performance monitoring • Right moment to specify operator tasks in detail, including performance indicators • Some open issues • Management of subscriber data, complete agreement with users • Application on packet data services • Network wide call recording service • Only average indoor coverage in cities, dedicated solutions needed for special sites • Usage based billing Management of large TETRA project

  16. Project organisation of VIRVE activities (early operation phase) Ministry of Interior VIRVE Board Co-operation groups Operational Group VIRVE Unit Supplier Operator Technical Group Distributor National Regional VIRVE-executive groups VIRVE-executive groups VIRVE-executive groups VIRVE Executive groups Management of large TETRA project

  17. Organisation of VIRVE activities (early operation phase) • VIRVE Board • Tasks: main decisions, project supervision • Members: ministry, main user groups • VIRVE Unit • Tasks: procurement, management, administration, economy, planning, organisation, supervision, tech. guidelines • Members: dedicated organisation Operational Group / Technical Group • Tasks: definitions, specifications, operational models • Members: main user groups • VIRVE Executive groups • Tasks: commissioning, start-up, user information, capacity planning, support for service implementation • Members: main user groups • Supplier / Operator / Distributor • Supplier: delivery of network equipment • Operator: network planning, operation, maintenance, reporting of network matters, provision of infrastructure • Distributor: terminal distribution and settings • Common 3-party groups: seamless co-operation Management of large TETRA project

  18. Summary of project organisation / parties in each phase Management of large TETRA project

  19. Experiences from regular operation phase • Some issues remained / can remain open during the project • More effort/attention in the planning phase should be put on • Management of subscriber data and billing • Implementation of applications • Network wide services/functionality • Indoor coverage in cities • Some user groups, like municipal organisations, are difficult to get • Marketing is required • Predefined product packages are required • Traffic per user is lower than expected • Coverage is more important than capacity Management of large TETRA project

  20. Why VIRVE was successful project? • VIRVE is part of an on-going project to improve the level of co-operation between the country’s different public safety organisations • All major government ministries have supported it • VIRVE is a network project only • Terminals and user applications do not belong to the VIRVE project, they are part of a parallel project managed by the user organisations • This approach has helped to avoid VIRVE becoming a mammoth project which is too costly and too complex to handle Management of large TETRA project

  21. VIRVE today • VIRVE project was successfully completed at the end of 2002 • Gradual substitution of old analogue systems during 2003 • VIRVE service is well accepted by users • Number of users is expected to grows up to 50.000 • Since beginning of 2004, the project organisation was converted to an operational one • State owned service provider Management of large TETRA project
