					MIND (Mobile IP based Network Developments)

Start date: 1/06/2001
End date : 30/11/2002
Action line: IST 2000 - IV.5.4
Clusters: Systems beyond 3G

Main Objectives
 Overall aim: To facilitate the rapid creation of broadband multimedia services and applications that are fully
 supported and customised when accessed by future mobile users from a wide range of wireless access
 Research areas: To extend the concepts of IP mobile networks. This includes: new network topologies -
 ad-hoc, self-organising and meshed networks; enhanced support for QoS, ad-hoc networks and self
 organisation at all layers of HIPERLAN/2; QoS support in IP-based mobile networks; investigation of the
 spectrum requirements for systems beyond 3G.
 Trials: The project will research the use of WLAN and an IP-based access network as a complement to
 UMTS for high bandwidth provision in hot spot areas.
 Delivery: To contribute actively to standards bodies and industry forums.

Technical Approach
The technical approach of MIND provides a vision of what shows a path towards 4G. The work will be based
on results of the IST project BRAIN. The project will take as a starting point the concept of an IP core,
accessed by a variety of technologies. It will develop this vision with business models and user considerations
(including scenarios – which will look at the user side of ad-hoc networks). From this the project will derive the
requirements on the network and air interface parts of the vision. In addition the project will conduct a trial –
practical research – into the use of HIPERLAN/2 and an IP-based access network, using IP QoS and IP
mobility management techniques, as a complement to UMTS and as a part of this vision. The project is not
concerned with the core IP network and will focus only on those aspects of the problem that specifically relate
to mobile. This is why we have the concept of an access network – where different IP QoS protocols could
run, for example, and where IP micro-mobility management would be introduced. The project will run a trial of
this access network and show HIPERLAN/2 systems running from this network. HIPERLAN/2 has been
chosen because it is a candidate system for 4G – it also represents a quantum leap in terms of bandwidth and
functionality (dynamic frequency allocation, self configuration, broadcast channels, convergence layers ...)
than current Wireless LAN systems. Our work is aimed much further than a simple demonstration of Wireless
LAN and UMTS hand-over – this has already been achieved by the use of Mobile IP. We are trying to
research how a unified UMTS, HIPERLAN/2 and ADSL could essentially offer multimedia services across
Europe at low cost, with high flexibility and fully convergent with emerging IP services.

Key Issues
 To investigate new business models beyond 3G – mapping the value-chain into the functional entities
 required for rapid and flexible multimedia service creation and support.
 To detail the scenarios that need to be supported by future wireless networks.
 To investigate, define and specify suitable mechanisms for authentication, security and accounting.
 To provide support - QoS, mobility management and security - for ad-hoc and self provisioned sub-
 networks attached to a fixed IP network.
 To investigate the opportunities offered by IPv6 for creating additional functionality.
 To develop and design protocols to support fixed-mobile convergence.
 To investigate and propose solutions to the complicated inter-related issues of scalability, performance,
 signalling load and QoS.
 To investigate and propose solutions for dynamic frequency and resource allocation mechanisms in
 support of ad-hoc and self provisioned networks.
 To investigate the generic support required at the layer2/3 interface for vertical handover and multi-homing.
 To study the spectrum issues raised by the MIND model.
 To investigate how the range and performance of HIPERLAN/2 can be increased to make it suitable for a
 wider range of scenarios including ad-hoc networks and supporting a full range of user QoS.
 To integrate a trial environment including systems such as WLAN (e.g. HIPERLAN/2), UTRA and IPv6
 based core network testbeds.
 To validate and evaluate basic functions and protocols specified by the IST project BRAIN: vertical (at IP
 layer) and horizontal handover mechanisms and QoS related aspects.
 To contribute actively to standardisation bodies and forums including ETSI, ITU, IETF, and H2GF as

Expected Impact
MIND will develop further the concepts elaborated by the IST project BRAIN and, thus, will show a path
towards 4G systems. It will design an access system which is optimised across application, network, and air
interface layer with regard to QoS and mobility management taking into account the requirements of future
mobile users. The resulting MIND trials will allow the validation of the concepts and protocols developed in the
BRAIN project, including mobile applications exploiting high data rates, QoS negotiation between terminals
and the access network, IP handovers, and integration with IP core networks over well defined interfaces. The
main conceptual work of MIND includes investigations of the performance limitations of the current
HIPERLAN/2 standard in terms of range and mobility, to reduce the gulf between it and the UTRA air
interfaces and investigations of the way in which ad hoc and self organising networks can be supported,
including the meshed (multi-hop) case and integration with wired networks. The results of the MIND work will
be disseminated through conferences, workshops, journals, and through the Internet. MIND will work to
contribute to standards groups for wireless LANs and ad-hoc networks and those efforts looking to harmonise
the 5GHz spectrum usage.
