Paper ID: 137 Title: Roaming of Advanced Telecom Services through Semantic Annotations Uploaded File Size: 259957 bytes Authors: Josef Noll josef@unik.no, Dumitru Roman dumitru.roman@deri.org, Marcin Pilarski Marcin.Pilarski@mini.pw.edu.pl

Abstract: This paper addresses the seamless service access with specific focus on roaming of advanced telecom services. Telecom networks provide voice and data connectivity in other countries, but advanced service roaming as e.g. location is not yet in place. The contribution of this paper consists in analyzing the current status of location roaming as an example of advanced telecom services. It highlights the complexity of location services, indicates both technical and sociological challenges for this type of service, and proposes WSMO based semantic annotations as a possible way of overcoming existing limitations. Finally, we show how our proposal is applied to a real use case – seamless access to the Orange and Telenor location services.

Roaming of advanced Telecom Services through Semantic Annotations

1. Introdution

  • pervasive services:
    • Awareness: Identification, Positioning, Location, Tracking, Tagging, Authentication
    • Devices: Smart Things, Smart Tags, Smart Assistands, Smart Rooms, Wearables
    • Action: Titi to update (2 paragraph) make the links mobile services (references)

here:

  • Technologies to make your services available (access to your services
  • the mobile device as a personal identifier (WWRF - SIG2 paper)
  • Seamless service access "makes your services available indnpendent of where you are"
  • Service roaming in telecom, specific focus on roaming challenges
  • Customer focus: Seamless (always online) - switch phone on and be online
  • status: GSM okay - bilateral agreement, GPRS - clearing house, advanced telecom service (location, presence) - no roaming

2. Problem introduction

  • advanced telecom service (location, presence) - no roaming
  • tackled today - not at all. Why not: to complex, too heterogeneous, not standardised, too inflexible (Josef)
  • Solution: Semantic Annotation of advanced Telecom Services
  • Selection of "location services", to be extended to presence services
  • answering the "theme of the conference"

3. Service description "location service"

3.1 Mobile Location information

  • Current status of advanced services Josef to send PATS link to
  • Overview over infrastructure (picture)
  • Location: GSM, UMTS, different ways to get location
    • Josef to provide examples cellinfo, eToA
  • Extension to new location information: WLAN location, RFID

3.2 Challenges

  • privacy (consensus, )
  • roaming access
  • variable interface (.wsdl), heterogenous presentation

4. Semantic Annotations

4.1. Role of Semantics Titi

  • advantages of a semantic regocnition

4.2. Case: Orange and Telenor location services

4.3. WSMO representation of location information

  • Marcin to describe process, from WSDL to WSMO

5. Roaming of advanced Telecom services

5.1. GSM and GPRS roaming

  • GSM bilateral agreement
  • GRX used for GPRS, common "clearinghouse", operators sign on with their GPRS service
  • Advanced service roaming: different descriptions, different presentations

5.2. Advanced Service Roaming

  • Assumme business SLA is in place
  • same annotation of services, e.g. WSMO --> show as a picture
  • different ontologies, Ontology mediation --> alternative picture
  • Status: current implementation in ASG, service roaming not established amongst operators.
