Agenda

• Objective– Describe location services and interoperability– Describe some current interoperability solutions– Describe current activities in location standard bodies, such

as OMA

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

FriendFinderTM

• 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.

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 …

A + B have different/multiple GSM and TIA standard protocols and messages to obtain locationC has a standard TIA message in its architecture (being considered in GSMD 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

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

RLP – Roaming Location Protocol

• For Lr interface between Location Servers

• Heavy lifting Is done , should be Ratified in 2Q/3Q 2003

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

PN- 4747

• Currently in version 24, should be ratified later this year

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
