Global Standards Collaboration GSC#10 28 August – 2 September 2005 Sophia Antipolis, France GSC Agenda Item: gsc10_grsc3_5.1, Location-based Services TIA TR-45 Standards Work Program on Location Based Services (LBS) Presented by: Cheryl Blum, TR-45 Chair Lucent Technologies 1 GSC 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 2 GSC User Plane Network LCS-y Target MS LCS-x Serving PDE Ref.pt 18 Serving PS LCS-z SMS/WAP Push Home PS L1 External LBS Client 3 GSC 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. 4 GSC 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) 5 GSC 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 6 GSC Control Plane Standards TIA-881 TIA-881 builds on the network architecture developed for JSTD-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. 7 GSC Old/Other slides 8 GSC 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 9 GSC 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 10 GSC 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 11 GSC 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 12 GSC 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 13 GSC 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 14 GSC 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 15 GSC 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 16 GSC Thank You!
