NEC Successfully Demonstrated Beyond-3G IP-based Converged MobileArchitecture
November 17, 2003
NEC Europe announced the successful completion of the three-year “Moby
Dick Project”, aimed at developing a seamless converged mobile network
architecture based on Internet Protocol version 6 (IPv6). The project
title “Moby Dick” stems from “Mobility and Differentiated Services in
a Future IP Network”, fostering the evolution of mobile and wireless infrastructures
toward the Internet and targeting the “Terrestrial Wireless System and
Networks” area of the Information Society Technologies (IST) programme.
An international consortium of twelve organisations from the private and
public sector in telecommunication, Internet technologies and network
operation, including NEC, launched the project to develop, implement and
evaluate a common IPv6 mobility-enabled network architecture, integrating
Authentication, Authorisation, Accounting and Charging (AAA or AAAC) services,
with support for Quality of Service (QoS). The group successfully demonstrated
the achievement of these aims at a public seminar held on campus at the
University of Stuttgart, Germany on November 6th. The initiation of the
next project, Daidalos, also supported by the EU’s IST program, which
will continue and strengthen the development begun with Moby Dick, will
commence immediately.
Aiming to fulfil the needs of present and future mobile communications
services, the Moby Dickgroup focussed on IPv6, developed and published
by the Internet Engineer Task Force (IETF) as a basis for their next generation
network architecture. The beauty of IPv6 mobility is that it offers smooth
evolution from existing 2G and 3G network architectures - meaning that
these will not become “obsolete” and dismantled before 4G or beyond can
come into force – while simultaneously allowing the plug-in of future,
yet to be developed network technologies. The Moby Dick architecture offers
seamless handover between network access technologies over IP, a function
crucial for effective video- streaming and audio communication.
The project was born amid the hyperbole of UMTS licence sales in 2000.
The Moby Dickparadigm was to be based entirely on the Internet, with obvious
cost advantages for operators and users, integrating licensed and unlicensed
radio access networks. The MobyDickgroup decided that the IP layer would
be directly on top of TD-CDMA. The TD-CDMA interface and the radio link
protocol would exist but other network elements, such as RNC, HLR, VLR,
SGSN, GGSN are replaced by functionally IP-based equivalents – MIPv6 home
agents and access routers, AAA Servers and QoS brokers. The data transmission
is pure IPv6 from end-to-end without a tunnelling protocol (like GTP),
offering significant advantages and simplified inter-technology handovers.
The recent demonstration proved that it was possible, with acceptable
quality, to transmit uninterrupted streaming to a mobile terminal; despite
changing it’s point of attachment to the network several times – employing
intra- and inter-technology handovers. Taking into account an initial
registration of a mobile terminal to the AAAC system, charging for authorised
usage and QoS negotiation throughout. Interfacing between three network
access technologies, WLAN, TD-CDMA and Ethernet, the team moved a mobile
terminal topologically among them, maintaining unbroken transmission of
audio or video streams. The demonstration is described in fuller detail
in the attachment ““Moby Dick” - Integrated Platform Final Demonstration-
An Explanation “.
The integration of AAAC services and QoS means that a commercial network
can not only deliver premium quality services that can be monitored to
ensure minimum standards are supplied, but can also charge premium rates
for the efficient provision of that service. The customer has a detailed
and accessible record of his usage and charges available in an online
database and the operator has a means of maintaining QoS to justify their
charges. Authentication confirms proof of users identity, Authorisation
gives permission for legitimate users to proceed, and Metering involves
the generation of raw charging data. During the Accounting and Auditing
phases, the provision of metering data for charging and the proof of service
are appraised. Charging is calculated based on the accounting phase and
security is maintained via standard IP security (IPsec).
In terms of what this means for users of future networks, it is safe
to suggest that seamless mobility will provide users with the most suitable
network access at any time and any place, offering significant cost benefits,
in addition to continuous maintenance of requested service levels and
communication security. Currently, parallel tests of this architecture
using PDA’s are being conducted. The benefits afforded by this architecture
will foster the evolution of mobile terminals into multifunctional communications
devices, capable of a whole range of tasks, including voice, emailing,
video streaming and conferencing, real-time access for uploading and downloading
via the Internet while the user is on the move. Telematics, navigation
or security and surveillance are other likely applications.
