Interoperability for Location Services

• Paul Hebert
• Principal Product Manager

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

Location Services Overview
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

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

Interoperability of Network Elements
Operators can plug and play with different
equipment vendors

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

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

GSM allows for LBS roaming through the Lg
interface TIA is more difficult, requiring shared
cell information

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
