Location Based Services TIA-881

» Wireless network capabilities that enable deployment of commercial Location Services (LCS)Wireless service provider LCSLCS applications external to the wireless networkMS-based services

» LCS applications can query for MS position latitude, longitude, altitude, velocityapplication requests Position Quality of Service

– accuracy, response time, position age, priority

Location Based Services TIA-881

» Wireless network provides an estimate of the Target MS’s geographic positionPosition estimate is represented as a shape

– The shape represents the uncertainty of the MS position– A number of different shapes can be selected according

to need e.g., ellipsoid point with uncertainty, ellipsoid point with

altitude and uncertainty

Velocity may be used to describe the speed and bearing of the Target MS– e.g., horizontal velocity with uncertainty

All position estimates indicate the time the position information was obtained

Location Based Services TIA-881

» Supports non-call related location servicesPosition can be obtained for an idle MS,

– CDMA Assisted Global Positioning System (AGPS) only

or for an MS that has started a call

» Supports call-related location servicesRequest for geographic position applicable only during

call

Location Based Services TIA-881

» User privacy protectionLocation Information Restriction (LIR) enables the MS

subscriber to restrict presentation of the Target MS’s position only to authorized entities– Emergency services take precedence over LIR

» TIA-881 builds on the network architecture developed for J-STD-036 Enhanced Wireless 9-1-1 Phase 2

» TIA-881 published March 2004

Location Based Services TIA-843

» Wireless Intelligent Network (WIN) capabilities for commercial Location Services (LCS) Intelligent Network application can use the MS’s

location information to provide enhanced subscriber services

Builds on TIA-881 network capabilities

» Call related LCS “triggered” by WIN call processing triggers

Location Based Services TIA-843

» Non-call related LCS “triggered” by non-call eventsNew capabilities enable LCS applications to request

automatic notification of changes in registration status and active/inactive status of Target MS– MS moves to a new system– MS moves to a new service area within a system– MS powers up– MS powers down or leaves a system– ….

LCS application can query for Target MS position when an MS change occurs

Location Based Services TIA-843

» Location Based WIN Service Drivers Fleet and Asset Management

– enables the location of an MS to be tracked Location Based Charging

– wireless subscriber charged different rates for services based on the MS location

Location Based Information Services– allows subscribers to access information services for which the

information is tailored based on MS location e.g., roadside assistance, hotel and restaurant locator

Enhanced Call Routing– calls routed to appropriate destination based on MS position

e.g., #GAS call routed to nearest gas station

» TIA-843 completed – to be published June 2004
