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

© 2002 Openwave Systems Inc. CONFIDENTIAL Agenda Objective –Describe location services and interoperability –Describe some current interoperability solutions –Describe current activities in location standard bodies, such as OMA

© 2002 Openwave Systems Inc. CONFIDENTIAL 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

CONFIDENTIAL Interoperability of Services - Future Wireless Location Application Location Server Wireless Network Wireless Location Application Location Server Wireless Network 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)

© 2002 Openwave Systems Inc. CONFIDENTIAL MLP – Mobile Location Protocol For Le interface MLP Version complete –Standard Immediate Location Service –Emergency Immediate Location Service –Standard Location Reporting Service –Emergency Location Reporting Service –Triggered Location Reporting Service

© 2002 Openwave Systems Inc. CONFIDENTIAL RLP – Roaming Location Protocol For Lr interface between Location Servers Heavy lifting Is done, should be Ratified in 2Q/3Q 2003

© 2002 Openwave Systems Inc. CONFIDENTIAL PCP – Privacy Checking Protocol For interface between a Location Server and Privacy Checking Entity (PCE) – aka a PPR or LIR PCP Version 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

© 2002 Openwave Systems Inc. CONFIDENTIAL PN Currently in version 24, should be ratified later this year

© 2002 Openwave Systems Inc. CONFIDENTIAL 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
