The Multinet communication system provides the network and application functionalities so that multiple simultaneous networks can be seamlessly handled to optimise communications in multiple dimensions; while sustaining the existing wireless and mobile industry and attracting new business revenue. The capabilities provided facilitate wireless broadband multimedia communication services of high quality and functionality, with an optimum cost, tailored to the communication offer provided. The project aims to provide the necessary networks and application functionality enhancements for seamless data communication mobility. The Multinet system allows users to benefit, without intervention, from ubiquitous access to broadband applications from simultaneous transparent network connectivity among the available access networks.
The project goal is to develop and validate on testbeds in France, Italy and Spain, an evolved Multinet communication platform which provide mobility to users in the context of wireless (IP based) networks, without modifying, either the existing network or the user applications, and in a seamless and transparent way. The priority and focus has been on multi-homing intelligent user PC terminals, providing intelligent network selection and dynamic bearer modifications between WLAN-WLAN initially and progressing to WLAN-UMTS / WLAN-WiMAX.
To achieve this strategic objective, a harmonized technological RTD approach was implemented by providing:
1. Tools and protocol for seamless broadband multimedia session delivery across heterogeneous networks.
2. Middleware techniques for application layer service to adapt to underlying bearer characteristics.
3. Mechanism for bearer services to adapt to the changing nature of multimedia applications.
Two user scenarios, which capture the broadband communication needs at work while on the move, were selected in order to increase the impact of the technology once demonstrated: High-Tech Machinery Maintenance and Utility Companies' Support Services.
Large enterprises and SMEs will obtain significant benefits through the new Multinet enabled multimedia services that permit managing their activities from anywhere, with reduced battery power consumption and better pricing conditions.
The project began with analysis of the current start-of-the-art and future trends in Mobile and Wireless Data Communications technology. Multinet then developed a communication system (a set of tools and protocols) to facilitate seamless and intelligent mobile broadband communication, providing mobility to users with improved performance of connectivity technology, and in a transparent way for applications and users. It investigated teleservices and supporting bearer services to adapt to the underlying time varying nature of radio channels. The application of the technology developed by Multinet in the two selected scenarios was to be examined with the aim of developing Reference Models for potential applications of different solutions. The aim was to achieve the highest flexibility in the communications through several networks simultaneously, making business tasks more intuitive, quicker and cheaper for enterprises/SMEs. These served to identify the specific SME needs to be created in relation to this communication technology. The needs defined the Multinet technology concepts and enabled continuous mapping of the technology development to the business needs.
