  1. Interoperability for Location Services Paul Hebert Principal Product Manager Location Server + Presence Server March 2003

  2. Agenda • Objective • Describe location services and interoperability • Describe some current interoperability solutions • Describe current activities in location standard bodies, such as OMA

  3. General Trends in Location Services • TIA moving from emergency to commercial services • Telecommunications Industry Association, mostly this hemisphere • GSM moving from commercial to emergency services • Global System for Mobile Telecommunications, mostly rest of the world • Operators looking for technical solutions to interoperability • Operators trying to figure out long-term business models around interoperability

  4. Location Services Overview PDE (A-GPS…) Switch (MSC) Location Server Provide Subscriber Location/Information Mobile Originated Request Wireless Location Application Wireless Network Home Location Register Manage Requests, Privacy, Business Rules, Obtain Location, Provide Record Mobile Terminated Request

  5. FriendFinderTM • FriendFinder is a Location Based Service (LBS) solution enabling subscribers to locate and communicate with friends. • Leverage network technology • Location • SMSC • WAP Gateway • Soon… IM and MMS • Protects location data • Protects privacy • Easy subscriber self-provisioning • Subscribers can set up individual or group lists

  6. Interoperability Drivers • Operators • Mix and match equipment, bring on-line quickly • Applications • Bring on-line in multiple networks easily • Enterprise • Services across networks • Asset tracking, fleet management, employee finder … • Consumer • Find friends/family in different networks • Use favorite services when traveling • Roadside help, local information, directions …

  7. Interoperability of Network Elements PDE (A-GPS…) Switch (MSC) Operators can plug and play with different equipment vendors Provide Subscriber Location/Information D C A Location Server Home Location Register B Obtain Location A + B have different/multiple GSM and TIA standard protocols and messages to obtain location C has a standard TIA message in its architecture (being considered in GSM D has a different standard protocol and message in its architecture Openwave Location Server has interoperated with 3 different HLR/MSC vendors in a single live network

  8. Interoperability of Applications LIF-MLP Specified interface let’s applications go on-line efficiently in multiple networks A A Wireless Location Application Location Server A A = Location Interoperability Forum Mobile Location Protocol interface GSM – Le interface was met de facto by MLP interface TIA – MLP interface is strong contender for standard solution for commercial services as well

  9. Interoperability of Services -Today Wireless Network Wireless Network Wireless Location Application MLP Location Server Roaming Wireless Location Application MLP Location Server GSM allows for LBS roaming through the Lg interface TIA is more difficult, requiring shared cell information

  10. Interoperability of Services - Future Wireless Network Wireless Network PPR (GSM) LIR (TIA) MLP (OMA) Wireless Location Application Location Server GSM = Lr (OMA) TIA = ISPOSREQ (PN-4747) Wireless Location Application Location Server MLP (OMA) PPR (GSM) LIR (TIA) Wireless networks will enable LBS roaming and validate subscriber privacy as they do it Lr = Location Roaming ISPOSREQ= Intersystem Position Request PPR = Privacy Profile Register LIR = Location Information Register

  11. MLP – Mobile Location Protocol • For Le interface • MLP Version 3.0.0 complete • Standard Immediate Location Service • Emergency Immediate Location Service • Standard Location Reporting Service • Emergency Location Reporting Service • Triggered Location Reporting Service

  12. RLP – Roaming Location Protocol • For Lr interface between Location Servers • Heavy lifting Is done , should be Ratified in 2Q/3Q 2003

  13. PCP – Privacy Checking Protocol • For interface between a Location Server and Privacy Checking Entity (PCE) – aka a PPR or LIR • PCP Version 1.0.0 under development, which supports: • Location Privacy Checking Service. • Early days,probably ratified next year NOTE: an interoperability standard for sharing geoposition information, such as map rendering, ZIP code translation, etc. also being considered by OMA Presence is also now part of the OMA

  14. PN- 4747 • Currently in version 24, should be ratified later this year

  15. Summary • Interoperability is key to long-term success of location based services • Some decent workarounds available today • More robust standardized solutions are well on their way • Business models to take advantage of interoperability are still being developed
