  • Multiple Consortia Provide LBS Standards
  • A Key Standard The GeoMobility Server
  • Standards at Work in the Chapter 2 Use Case
  • Standards in Korea
  • Conclusion

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
Standards of LBS (1/3)
  • Information and communications technology
    standards are important to the commercial rollout
    of LBS and the fulfilment of their potential

Geospatial data

H/W and S/W
5
Standards of LBS (2/3)
  • Standards are Important to LBS Users

Open service and information framework enables
roaming between location cells
6
Standards of LBS (3/3)
  • Standards are Important to LBS Providers

With open interfaces, applications can access
many sources of content and services
7
Brief History of Standards (1/2)
  • With pahase I architecture model, most
    carriers/operators took an approach in which they
    simply opened up prestandards interface access to
    their network MPC/GMLC to all spatially enabled
    applications residing outside the network
    firewall in the IP domain.

Approach for Carrier/Operator LBS Architectures
8
Brief History of Standards (2/2)
  • Due to the integration problems encountered with
    the Phase I approach, carriers/operators chose to
    implement two additional components within the
    core LBS architecture model
  • Phare II model ensures that the carrier/operator
    has complete control over how any application
    developer interfaces to the core network, and it
    dramatically reduces implementation costs

Approach for Carrier/Operator LBS Architectures
9
Standards Support LBS Business Models (1/4)
  • Technologies for location service
  • Wireless communications
  • Position determination
  • Store, serve, and apply georeferenced data in
    response to queries

10
Standards support LBS Business Models (2/4)
  • Todays reality of service technology
  • Despite telecom industry mergers and
    acquisitions, the number of carriers, service
    providers, application providers, and content
    providers is growing
  • Standards
  • To maintain integration among even a target
    subset of the possible permutations of devices,
    Location Engines, service providers, and content
    providers
  • Saving time, money and reducing business risks

11
Standards support LBS Business Models(3/4)
  • LBS standards benefit providers in the LBS value
    chain
  • Increased billable utilization of carriers
    spectrum and wireless network
  • Niches for providers with special products and
    services
  • A business case for different content providers
  • Expansion of LBS from a niche service to a mass
    market service
  • GSM Assorication, AOL, Microsoft, and AAA

12
LBS Value Chain
13
Multiple Consortia provide LBS Standards(2/2)
14
Open GIS Consortium (OGC)
  • opens Initiative starting from Oct. 2001
  • involves a broad and complex set of geospatial
    software interoperability issues at the level in
    the communications technology stack
  • Working Groups

  • now merged with OMA
  • addressed early and obvious problems related to
    the multiplicity of methods for location
    determination

20
LIFs Mobile Location Protocol
  • MLP serves as the interface between a location
    server and a location-based application

21

30
A Key Standard The Geomobility Server (GMS)
The Relationship between LIFs MLP, OGCs
GeoMobility Server and ASPs
31
A Key Standard The Geomobility Server (GMS)
A typical service/request response via the
GeoMobility Server
32
A Key Standard The Geomobility Server (GMS)
  • OGCs GMS provides open interfaces to core
    services for LBS
  • Route determination
  • Determine route and navigation information
    between locations
  • Location utility
  • Geocode adress -gt X, Y
  • Reverse Geocode X, Y -gt Address
  • Presentation
  • Create display inforamtion showing map, route,
    POI, or route instructions
  • Gateway
  • Obtain position of a moble terminal from the
    network
  • Directory Services
  • Search for POIs

33
GMS
  • basic information construct used by the
    GeoMobility Server and associated Core Services
  • Consists of well-known data types and structures
    for location information
  • Defined as application schemas that are encoded
    in XML for Location Services (XLS).

34
Use Case Example
  • How a Position ADT might be used

Q Joe wants to see where his house is located
on a map One way to do this is to have the
Geocoder Service geocode his address, thus
determining a Position ADT
35
Standards at Work in Find Friend
  • Use Case in Chpater 2
  • developen by Kivera for AT T
  • Application was developed before most of the LBS
    standards described had been developed, Kivera
    could not take advantageof those specifications
  • How the standards might be applied in this
    application?

36
Kivera Web Demo
37
Use Case Find Friend
Geocoding/Reverse geocoding
Geocoding/Reverse geocoding
  • receive latitude/longitude coordinates
  • pinpointing the location of a users
  • mobile phone
  • resolve these positions come from a
  • Nortel GMLC
  • subscriber would connect to the carriers
  • portal to request service
  • portals front end would transmit the
  • request to the GeoMobility Server
  • through an interface implementing the
  • OpensLS specification
  • GMS would use the LIF MLP API to
  • get the subscribers coordinates from
  • the GMLC/MPC
