  1. Agenda Item: gsc10_grsc3_5.1, Location-based Services TIA TR-45 StandardsWork Program onLocation Based Services (LBS) Presented by: Cheryl Blum, TR-45 Chair Lucent Technologies

  2. User Plane LBS • IP-Based Location Service • Extension of the legacy network location services capabilities • Uses IP-based protocols (TCP/IP, WAP etc.) • The MS is a peer with the network elements • Offer IP Services comparable to legacy service drivers • Provides ‘one shot’ or periodic positioning • ‘Warm’ mobiles can obtain position without network interactions. • Includes security capabilities • LBS client can be in mobile, network or external • Supports cdma2000

  3. Serving PDE Target MS Serving PS Home PS External LBS Client User Plane Network LCS-y Ref.pt 18 LCS-x LCS-z SMS/WAP Push L1

  4. Network Elements • MS – Mobile Station with User Plane LBS capabilities. • PDE – Position Determining Entity. Interface to network positioning hardware. • PS – Position Server. Roamers served by Serving PS cooperating with Home PS. • External LBS Client – An application external to the wireless network.

  5. User Plane Standard • PN-3-0131 to be published as TIA–1020 in 2005 • Security framework being defined in 3GPP2 S.P0110 • Designed to be compatible with the developing OMA SUPL • MS positioning protocol (based on A-GPS) is TIA-801-A (Position Determination Service for cdma2000)

  6. Control Plane LBS • TIA-881 • Wireless network capabilities that enable deployment of commercial Location Based Services (LBS) • External clients can query position via Home System. • MS can initiate positioning by dialing a feature code. • Subscribers can restrict positioning, or turn it off entirely. • Positioning allowed when mobile is idle or in a call. • Emergency Service positioning has precedence. • Provides latitude, longitude, altitude, velocity • Requests include Position Quality of Service (PQoS) • accuracy, response time, position age, priority

  7. Control Plane Standards • TIA-881 • TIA-881 builds on the network architecture developed for J-STD-036 (Enhanced Wireless 9-1-1 Phase 2) • TIA-881 was published March 2004 • TIA-843 • Builds on TIA-881 to provide positioning triggered by WIN (Wireless Intelligent Network). • Non-call events, such as moving to a new system, can be a trigger for positioning. • TIA-843 was published August 2004 • TIA-801 • A-GPS positioning between MS and network.

  9. 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

  10. 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

  11. 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

  12. 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

  13. 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

  14. 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

  15. 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

  16. 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
