Why excitement about location based services
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


Service provider needs for mls
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


Shortcomings of other solutions
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


Access7 location approach
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

Locating the handset basic cell id
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


Locating the handset timing advance
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


Locating the handset rx lev
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


Locating the handset s w enhancement
Locating the Handset : S/W Enhancement

A721

  • Track moving subscribers, relate to roads & railways (30% subs are moving)

  • Grid Map data analysis

  • “Learns” RF characteristics


Key features
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
