  • 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 Wireless Location Application Wireless Network Home Location Register Mobile Originated Request Mobile Terminated Request Manage Requests, Privacy, Business Rules, Obtain Location, Provide Record Provide Subscriber Location/Information Switch (MSC) Location Server PDE (A-GPS…)
  • 5. FriendFinder TM
    • 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
    • FriendFinder is a Location Based Service (LBS) solution enabling subscribers to locate and communicate with friends.
  • 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 Location Server Home Location Register Obtain Location Provide Subscriber Location/Information A B C D 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 Operators can plug and play with different equipment vendors Switch (MSC) PDE (A-GPS…)
  • 8. Interoperability of Applications Wireless Location Application Location Server LIF-MLP Specified interface let’s applications go on-line efficiently in multiple networks 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 A A A
  • 9. Interoperability of Services -Today Wireless Location Application Location Server Wireless Location Application Location Server MLP MLP Roaming GSM allows for LBS roaming through the Lg interface TIA is more difficult, requiring shared cell information Wireless Network Wireless Network
  • 10. Interoperability of Services - Future Wireless Location Application Location Server Wireless Location Application Location Server PPR (GSM) LIR (TIA) MLP (OMA) MLP (OMA) GSM = Lr (OMA) TIA = ISPOSREQ (PN-4747) 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 PPR (GSM) LIR (TIA) Wireless Network Wireless Network
  • 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
