Mission

  • To support IPv6 based "Layer-3" mobility solutions: Support heterogeneous current and future access technologies, thus optimising solutions for the concrete requirements. Moby Dick focuses on Ethernet, Wireless LAN (802.11b) and TD-CDMA, but these technologies should be seen as examples. Others, i.e. Bluetooth, 802.11a or yet unknown wireless and wireline technologies, may replace them.
  • To overcome two major deficiencies of Internet solutions compared to traditional mobile (2G and 3G): Provide a contracted Quality of Service and AAA and Charging support. This is a prerequisite to enable current and new business models with co-operating players and domains.

Main Objectives

  • To facilitate the development of seamless access to existing and emerging IP-based applications.
  • To propose an architecture for wireless Internet access by developing new mechanisms for seamless hand-over, QoS support after and during hand-over, AAA, and charging.
  • To facilitate new business opportunities for operators, manufacturers, services providers, and content providers for wireless, access, and backbone technology and services.
  • To contribute actively to standardisation bodies, such as Internet Engineering Task Force and Internet Research Task Force.

Technical Approach

In order to continue to evolve 3rd Generation mobile and wireless infrastructure towards the Internet - targeting IST 2000 IV 5.2 "Terrestrial Wireless System and Networks", the project Moby Dick defined, implemented, and evaluated an IPv6-based mobility-enabled end-to-end QoS architecture starting from the current IETF's QoS models, Mobile-IPv6, and AAA framework. A representative set of interactive and distributed multimedia applications served to derive system requirements for the verification, validation, and demonstration of the Moby Dick architecture in a test bed comprising TD-CDMA, 802.11 Wireless LANs and Ethernet.

Key Issues

  • Definition of a common architecture integrating QoS, IPv6 mobility, and AAA (out of the separate architectural approaches for each component currently provided by the IETF) with respect to wireless issues.
  • Implementation and evaluation of an IPv6-based end-to-end technological approach to fulfil the requirements of present and future mobile communication services.
  • Implementation and evaluation of QoS models (e.g. Differentiated Services) in highly dynamic and heterogeneous network topologies. Understanding of QoS models is normally restricted to relatively static environments.
  • Definition of a suitable charging concept, which would enable permanent mobile IP-based services on a large scale .
  • Trans-European trial to test the implementation by using SOKRATES-ERASMUS exchange students as test-users.
  • Actively participate in IRTF (Internet Research Task Force) AAAArch (Authentication, Authorisation, and Accounting Architecture) working group, and monitor in particular ETSI, 3GPP (3rd Generation Partnership Project), MWIF (Mobile Wireless Internet Forum), IEEE (in particular 802.11) and WWRF (Wireless World Research Forum).
  • Follow and actively influence ongoing relevant IETF standardisation activities.

The evaluation of the implementation is being done in a distributed trial.

Structure of the Trial NetworkStructure of the Trial Network

NEC Focus

  • Compare performance of various handover techniques: standard MIPv6, MIPv6 enhanced with fast handover (FMIPv6), hierarchical MIPv6 and combinations of all using simulations via ns-2 (completed).
  • Specify and implement fast handover (completed)
  • Specify and implement IP-based paging (completed)
  • Integrate fast handover and paging with AAA and QoS (completed)
  • Support of trials (ongoing)

Expected Impact

The architecture is expected to support mobile IP end-to-end communication with QoS, seamless hand-over and all necessary AAA and charging mechanisms to satisfy the user and the network operator. The solution will allow operators to implement new (charged service) business models.

The implementation will be validated in a real environment field trial. The results will be presented in conferences, journals, and workshops. A major part of the dissemination will be the contribution to the standardisation bodies, IETF and IRTF, with a significant influence.
