NWhy 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

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 roadmap that 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

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

NacceSS7 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

NLocating 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

S

NLocating 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

S

NLocating the Handset : Rx Lev

Handset makes measurements on 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

NLocating the Handset : S/W Enhancement

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

Grid Map data analysis

“Learns” RF characteristics

NKey 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
