GSC9/GRSC_015 TIA TR-45 StandardsWork Program onLocation Based Services Presented by: Cheryl Blum, TR-45 Chair Lucent Technologies
Location Based Services • TIA-881 • Wireless network capabilities that enable deployment of commercial Location Services (LCS) • Wireless service provider LCS • LCS applications external to the wireless network • MS-based services • LCS applications can query for MS position • latitude, longitude, altitude, velocity • application requests Position Quality of Service • accuracy, response time, position age, priority GSC-9, Seoul
Location Based Services • TIA-881 • Wireless network provides an estimate of the Target MS’s geographic position • Position 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 GSC-9, Seoul
Location Based Services • TIA-881 • Supports non-call related location services • Position 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 services • Request for geographic position applicable only during call GSC-9, Seoul
Location Based Services • TIA-881 • User privacy protection • Location 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 GSC-9, Seoul
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 GSC-9, Seoul
Location Based Services • TIA-843 • Non-call related LCS “triggered” by non-call events • New 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 GSC-9, Seoul
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 GSC-9, Seoul
Location Based Services • IP-Based Location Services (PN-3-0131, TIA-1020 • Extension of the legacy network location services capabilities • Develop IP interface capabilities • Offer IP Services comparable to legacy service drivers • Fleet and Asset Management • Location Based Charging • Location Based Information Services • Enhanced Call Routing • Support mobile, network, and external LCS Clients • TIA-1020 scheduled to be published 4Q04 GSC-9, Seoul
