  3. Location Based Services : Revenues Source : OVUM

  4. Why Excitement About Location –Based Services ? • Strategically Important • New customer ownership • Mobile Location Services important component & enabler of future services • Market Potential • $15Bn by 2006 • Growth engine • Will be a “hygiene factor” • Customer expectation and regulatory pressure

  5. Service Provider Needs for MLS • Get experience now from early deployment of location based services with minimal initial investment • Provide location services to current customers without handset change out • Technology roadmapthat enables ramp to mass market deployment of location services & support for 2.5 & 3G • Platform that allows for the broadest portfolio of new location services (business & consumer applications) • Control the information that enables new application areas

  6. Shortcomings of Other Solutions • E-OTD – medium accuracy but v.Expensive ; replacement of legacy handsets, impact on n/w infrastructure, handset query required, new technology • GPS / A-GPS – cannot locate during call, poor indoor capabilities, expensive handset replacements, time-to-lock, unsuitable for mass market applications • Cell-id – poor accuracy • Enhanced cell-id - enhanced data difficult to get from network equipment in necessary quantities

  7. acceSS7 location approach • Enables a broad variety of business and consumer applications • Best platform for mass market deployment- highly available & accessible database of location data for all active & idle subscribers • Good location accuracy at considerably lower cost than other techniques- no expensive handset / base-station mods / RF receivers • Rapid realisation of new location services revenue - works with all legacy (GSM) handsets from day one • Near zero latency – refresh twice per second for active calls • Totally passive - does not threaten network performance

  9. Locating the Handset : Basic Cell-id • Cell-ID : the cell (or base station) the handset is connected to • Operators know where the cell sites are • Accuracy depends on cell density

  10. Locating the Handset : Timing Advance • Timing Advance is a GSM specific parameter • Measures the round trip delay between the handset and the base station to ensure correct timing for RF burst arrival

  11. Locating the Handset : Rx Lev Zoom … • Handset makes measurementson the air interface to facilitate hand-over decisions • The measurement reports contain power levels for the serving & neighbouring cells • This RxLev can be triangulated to estimate base station to handset distance, esp. whencombined with RF planning data

  12. Locating the Handset : S/W Enhancement Zoom … A721 • Track moving subscribers, relate to roads & railways (30% subs are moving) • Grid Map data analysis • “Learns” RF characteristics

  13. Key Features • Totally passive • offloads effort from network • Vendor independence • Information accessibility , availability & volume • Scalable • Twice per second location measurements • Correlation (e.g. Rx power level, Tracking handovers) , GIS analysis & floating car data for increased accuracy • Platform designed for purpose (network elements can’t monitor!) • Flexible and conforms to GSM standards

  14. Service Provider Needs for MLS • Get experience now from early deployment of location based services with minimal initial investment • Provide location services to current customers without handset change out • Technology roadmapthat enables ramp to mass market deployment of location services & support for 2.5 & 3G • Platform that allows for the broadest portfolio of new location services (business & consumer applications) • Control the information that enables new application areas
