It is expected that systems beyond 3G will provide seamless access to broadband services over a wide range of air interfaces and will allow new business models for providing and running these services and the underlying networks. Considering these user requirements on future mobile networks, the project MIND will extend the concepts of a broadband multimedia IP-based radio access technology. The research conducted by MIND includes new network topologies like ad-hoc, self-organising networks, improved QoS support in IP mobile networks, enhancements of HIPERLAN/2 and investigations of spectrum requirements for systems beyond 3G. In this context, HIPERLAN/2 is seen as part of a 4G system, which complements traditional cellular systems such as UMTS. The resulting concepts of the MIND access network will be validated by running trials based on UMTS, HIPERLAN/2, and IPv6 testbeds. Results will be contributed to relevant standards bodies.
1. 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 technologies.
2. 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.
3. 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.
4. Delivery: To contribute actively to standards bodies and industry forums.
To achieve the objectives of MIND, its activities are grouped in 6 workpackages:
1. Services and Applications - This area aims to define and improve mechanisms for the seamless provision of IP services and applications, to develop new business and service models.
2. Network support - To support mobile Internet applications, MIND will specify an advanced IP network layer that will meet the following objectives: support for ad-hoc and self provisioned networks attached to a fixed IP network; investigation of features offered by IPv6; support of multi-homed terminals and vertical handover over multiple air interfaces; development of protocols to support fixed-mobile convergence; investigation of the inter-related issues of scalability, performance, signalling load and Qos.
3. Air interface - This area focuses on allowing connections to a common IP network over a range of air interfaces as well as offering support for ad-hoc and self provisioned networks at physical and link layer. It will also study spectrum issues raised by the MIND model of a 4G system and will investigate how to extend the range and the performance of HIPERLAN/2 to make it suitable to a wider range of scenarios.
4. Trials - Key concepts of the MIND architecture will be proven by running trials based on UMTS, wireless LAN and IPv6 testbeds. Thus, the project will gain practical experience in particular on handover mechanisms and QoS negotiation. The four technical areas described above will be supported by the project management (5.) and standardisation and dissemination activities (6.), which aim to secure the acceptance and adoption of MIND concepts.
The MIND work carried out in the different areas will be based on results of the IST project BRAIN.
Two main milestones are defined for the conceptual work resulting in (M1) specifications for service scenarios, business models, access network architecture, IP convergence layer, and (M2) specifications for protocols, HIPERLAN/2 enhancements, and spectrum requirements.
The trial activities are structured in (M1) intermediate trial configurations and (M2) final testbeds and evaluation of trials.
Standardisation and dissemination activities accompany above two activity streams.
The following technical achievements can be highlighted:
1.Concept definition and implementation of a an End-to-End negotiation protocol.
2.Development of new models for future, flexible, mobile networks.
3.Development of network architectures for wireless and mobile router extensions to an IP radio access network.
4. Proposals and analysis of Mobility management and QoS schemes for ad-hoc fringe networks.
5. Specification of the IP Service Specific Convergence Sub-Layer of HIPERLAN/2.
6. Detailed evaluation of enhancements to HIPERLAN/2 supporting higher speed and new scenarios.
7. Implementation of the BRAIN Candidate Mobility Protocol (BCMP), a micromobility protocol designed during the predecessor project BRAIN.
8. Integration of mobility management and adaptive applications into a single trial.
