Beijing Government Shared TETRA Network -- The Lagest TETRA Network in Asia Ding Rui Vice President Beijing Just Top Net. Com. 18 th, May, 2005
Background-Why Shared network • The Existing analogue system can’t meet requirements any more • 9 separated analogue trunking networks , outdated technologies, not compatible and being connected • different government agencies can't efficiently communicate with other in the big events or in emergency situation • overlap investment with very low frequency efficiency • the need of Olympic 2008 need up-to-date and shared PMR systems • Beijing government committed to setup a digital PMR system in the bid for the host of Olympics 2008 • The Ministry of Informatization Industry’s official document asked 800 MHz frequencies used in existing private analogue networks needed to be returned before 31 st , Dec, 2005 Police Fire Ambulance … Other agencies
Background: Why TETRA? • Two alternative technologies were competing in China: TETRA and IDEN • Why TETRA? • the only digital PMR technology based on open global standard • Rich dispatching functionalities designed for authority communication • Fast call setup • Security features • Disaster capacity • Redundancy on all levels
The Targets of the Project The Phase 1 System Capacity : 50 k subscribers Implementation schedule: trial use by end of 2003 mass use in 2004 coverage: urban area county central area Communication probability: over 90% The Phase II System capacity: 150 k-200 k subscribers Schedule: implemnt in 2005 completed in 2007 coverage: almost all the area of BJ other Olympic cities Communication probability: over 95%
The Milestones of the Project the Mayor’s round table meeting decided the model of the shared network July, 2002 Dec, 2002 the operator company, Beijing Just. Top Net. Com registered. Mar, 2003 the contract signed with Nokia Sep, 2003 the network is in trial operation already, covering city areas Mar, 2004 The Government Agencies start to join the network June, 2004 The phase I network completed Sep, 2004 Oct, 2004 Sep, 2005 Beijing Police started to join the network The opening Ceremony in Great Hall of the People All Police offices will be in the network
The operation model • • The new model in China PMR market: – “Operator owned network, Government Purchase services” – Decided by the Mayor’s round table meeting in Beijing Just Top Netcom, was established for network operation, and was granted a first digital trunking license in mainland China • Bei. Jing Government Radio Network Administration Center(BJNAC) , under Beijing Municipal office of Informatization, was established for operational management. • BJNAC has signed service agreement with Just Top Net. Com Network Supplier (Nokia) Supply contract Operator Service. Government (Just Top) contract (BJNAC)
Current Status of the Beijing Network • The scale of the network – 2 DXTip – 174 TBS – 50000 subscriber capacity – Covering Beijing city area , key counties and the main highways • 8000 subscribers now • 30000 subscribers by 2005
The network Coverage
Indoor Coverage for key buildings 1. TETRA base station + repeaters Example: State Opera House: Two floors in underground 201 section Entrance Parking area Two floor in underground 5 -floor aboveground Two Floors in underground Implementation Plan 1 -floor aboveground 203 Section 202 Section-Main area (Music Hall、Opera House) 2. Share indoor coverage solution with PHS system
Mobile Operation Center for Events and Emergency • Mobile Operation Center(MOC) is for emergency situation or big events to provide extra capacity • Satellite link has been well tested between MOC and TETRA switch. DXTip • Mobile Operation Center(MOC) now consist of three parts: • Transportable Base station • Satellite transmission system • Power Supply • The Integrated MOC will be available in this summer
Government Agenices in the Beijing TETRA Network • Current Customer Segments – Police – City administration – Ambulance services – Law Enforcement – Water Conservancy – Disease Control • Customer Segments by 2005 – – – Traffic Police National Security Fire Judicial Customs

End user organisations Users on the field Fire Police Health Operational management Technical management Nokia as infra supplier etc. • Government Oranizations work in VPN • Can have full control of own communication • Management of own radio- and Ws-users • Control of own applications • Numbering planning inside own frame • Steers and influences operational management layer
Applications support and Data Services in the Network • • • Network wide Secured Data Services SDS – Two way messaging Status service – Own number range for organisations and common values IP packet data – Very fast set up time Sophisticated Open Interfaces for Applications Increased Service Interaction with Selected Alternate/Simultaneous Voice and Data – Interoperability co-ordination Applica. API Beijing Government Shared TETRA Network Voice + Data API Application
Beijing Government Applications Development • Beijing Government sponsors and manages the application development based on the TETRA network • Several Applications development Projects are going on • Police-Vehicle/Person Automatic Location System • Police Mobile Data System • Traffic Management (POS) Data transmission System • End to End Encryption • Computer-Aided Dispatcher workstation • Customer Care System • The User organizations and Local companies actively involved in the projects The projects proceed very smoothly and application tests have been done with TETRA network
Application example Locationing • Locationing applications are very important for PSS users in Beijing • The Beijing TETRA Network support 3 types of locationing: – GPS based accurate locationing • mobile station direct connect to GPS receiver • New TETRA handportable integrated with GPS receiver – Network based locationing • supported by existing TETRA Terminals – TETRA base station based locationing -- No expecial support needed in terminal
Application example Intelligent AVL/APL system for Beijing Police • Sends compressed data over air interface to minimized air interface load • Does not send a new message before the location is changed more than the preset value. • Congest control is applied • Differential GPS technology are used, the locationing accuracy is 2 -5 meters Data collection Database TCS SDS Beijing Government Shared TETRA Network Router GIS server TCP/IP LAN Information Mangement
Application example Police Mobile Data Access Application Database server Intranet WAP server The Beijing TETRA Network Direct Information enquiry in the field office databases: - person registers - missing persons info - wanted persons - car register info - stolen cars info - Traffic Regulation Violation record
