Integrated Platform for Location-Based Services
Project Objectives
 To design and implement an Integrated Platform for
Location Based Services (LBS) for:
 Service Creation
 Service Deployment
 Service Provision

Integrated Platform for Location-Based Services
Main Advantages of PoLoS (1/2)
 Portability: platform independent of specific hardware/operating
systems
 Re-usability: generic platform, decoupled from service logic - basic
components unaffected by dynamic new service introduction
 Independence from underlying technologies:

platform not bound to specific network technologies. Covers both outdoor
and indoor environments (GSM/GPRS, UMTS and WLAN)

platform not coupled with specific GIS

Open interfaces towards the GIS, the network and end-user devices
 Support for many operation paradigms (e.g., server push, client pull,
event scheduling)
Integrated Platform for Location-Based Services
Main Advantages of PoLoS (2/2)
 Flexible Service Handling
 Service Creation Environment handles the XML-based service specification
 service logic fully covered by the platform. Service specified through the
SCE, deployed & executed in the kernel
 Roaming across different infrastructures (e.g., moving from an
outdoor/GPS to an indoor/WLAN environment)
 Generic system infrastructure tied with generic business model
 separation between service creation, service provisioning and the network,
allowing each function to be handled by independent (yet cooperating)
organisations.

PoLoS Consortium Composition
 Highly focused project involving 7 organisations,
from 5 European countries, with complementary
know-how:
 Two major telecom manufacturers with expertise on
systems engineering and standardisation
 Two R&D institutions with expertise on mobile networks
and services
 Two R&D partners specialised in G.I.S.
 A mobile network operator
Integrated Platform for Location-Based Services
Target Audience
 Providers of innovative telecommunications services (LBS in
particular)
 Telecom operators wishing to extend the range of their VAS by
exploiting positioning capabilities offered by their infrastructure
 Large organizations wishing to exploit LBS platforms internally
(e.g., fleet-management)
 Other Organizations: Universities, R&D centers or industries
wishing to exploit LBS technologies in their premises
Integrated Platform for Location-Based Services
Exploitable Results
 A new platform: allows the deployment and provision of LBS
over different network infrastructures
 A Service Creation Environment / Specification Language:
easy service creation and deployment
 A prototype service: deployment and provisioning using the
developed platform
 A generic process model: allows service providers to fully
realise the potential of the developed platform
Integrated Platform for Location-Based Services
Definition of a Business Model
 An architecture for:
 Product
 Service
 Information flows
 Business Actors and their Roles
 potential benefits for the various Business Actors
 sources of revenue
Integrated Platform for Location-Based Services
PoLoS Business Models
 An important aspect of the PoLoS project is the
introduction/ proposal of a business model specially
designed, tailored to organisations that exclusively provide
Location Based Services to various sectors of economic
activity. Such models will be structured appropriately to
optimally exploit the outcome of PoLoS.

Service Specification Language
 The specification language consists of the following parts:
 Service control logic
 Configuration options
 Embedded components
 Web Server pages
 WAP pages
 Custom java classes/libraries
 Midlets
 These parts are defined in a single XML file, which completely
specifies the service.
