Dienste integrierender Bahnmobilfunk. DIBMOF-VALID Schlussbericht

In the project DIBMOF-VALID, the transmission parts of the superproject DIBMOF-VALID, following the results which have been worked out up to 1996, have been finalized successfully in the timeframe January to September 1997. The work packages radio network optimization, spezification of FZB (i.e. Train Control System) quality of services and channel error model have been finalized. Optimization of the radio network led to a reduction of more than 30% of the network elements without reducing transmission quality, which was validated on the trial site. For the train control system FZB, QoS parameters have been defined and specified. Also measuring methods have been specified. The parameters could not be fully validated. A channel error model has been designed as a result of the collected measuring files and is available for simulation. Further Results cover the finalization of the technical specification, design specifications for both driver and controller MMIs (man machine interfaces) and a new redundancy concept for the fixed transmission lines of the base stations.
