Welcome to BOSS project website


Technical elements:

Launched by France, Spain, Hungary and Belgium under the framework of the EUREKA Celtic inititiative, BOSS project started in Oct. 2006 and has ended in June 2009.



Project Abstract:

The BOSS project aims at developing an innovative and bandwidth efficient communication system to transmit large data rate communications between public transport vehicles and the wayside to answer to the increasing need from Public Transport operators for new and/or enhanced on-board functionality and services, such as passenger security and exploitation such as remote diagnostic or predictive maintenance. In particular, the BOSS concepts will be evaluated and demonstrated in the context of railway transport. As a matter of fact, security issues, traditionally covered in stations by means of video-surveillance are clearly lacking on-board trains, due to the absence of efficient transmission means from the train to a supervising control centre. Similarly, diagnostic or maintenance issues are generally handled when the train arrives in stations or during maintenance stops, which prevents proactive actions to be carried out.
To achieve this goal, the BOSS project intends to develop a communication system relying on an IP gateway inside the train that will enable the communications both inside the train, for communications inside carriages and for mobile passengers and controllers, and outside the train, mobile in the terrestrial reference frame, with a link towards wireless base stations (e.g. WiMAX). The BOSS project will consequently work on a dual mobility level, and will work to guarantee a differentiated Quality of Service for the different targeted services. The project partners will also work on video surveillance applications adaptation, in particular via robustification of the existing tools and development of behaviour analysis algorithms to ensure that the passenger security is handled in the best possible way.
As an enhanced level of railway passenger security services is highly demanding in terms of bandwidth, this application thus represents a good case study to validate the BOSS concepts. Moreover, taking advantage of the bandwidth made available both downlink and uplink, wireless communications solutions such as video on demand, internet access, travel information services … which greatly interest travellers, will be integrated in the global BOSS framework via an adapted level of service management.
The BOSS project, with its IP gateway, is willing to offer the mobile train the possibility to inform a control centre both on security, and trains exploitation related issues, and consequently to greatly increase the user protection as well as demonstrating the possibility to offer at the same time video on demand, on-board information and telecommunication services to the travellers. Validation will be performed through on-line tests on train in revenue service.



Contribution to CELTIC “Integrated Telecommunications Systems”:

To reach the objectives envisioned by the BOSS partners, that is the offer of on board wireless services, predictive maintenance and security solutions by means of video surveillance, alarms and maintenance information transmission, a system offering interconnectivity with a guaranteed QoS level both inside the carriages and between the train and the way side will be developed. The external link (train-way side; wireless, e.g. WiMAX and UMTS) will offer a bi-directional connection with a control centre able to manage alerts and video-surveillance activities, and the internal (wired and wireless; e.g. WLAN) will provide a connection inside the train with mobile supervisors (e.g. train controllers). The internet access and other on-board services for the users require lower QoS but higher throughputs and is thus foreseen to be delivered with a high throughput wireless access that could be the same as the security access with different QoS priorities. Moreover, the railways being deployed both in suburban areas and in the countryside, vertical handover issues are to be considered on the external wireless link, which adds a second complexity level to the interconnectivity and justifies that mobility over IP, QoS and handover issues are considered together by the BOSS project and not studied separately. The transmission of several multimedia streams from several trains to a control centre will set up the problem of radio resources management and multi-user accesses. Thus, the BOSS project will contribute to the CELTIC “Integrated Telecommunications Systems”
A test-bed platform demonstrating in a real train this dual-mode approach with guaranteed QoS will be developed to validate the BOSS approach, and two Europeans well known end users will be involved in the project to evaluate concretely the different technical outputs of the project. This way, the BOSS project will promote the CELTIC “Pan-European Lab”
