GSM-R International: Europas Bahnen wachsen zusammen

摘要

Die Einführung des digitalen Zugfunks GSM-R macht nicht nur in Deutschland, sondern auch europaweit deutliche Fortschritte. Die moderne Mobilfunktechnologie bildet mehr und mehr den einheitlichen Standard und trägt damit wesentlich zur Interoperabilität der Bahnsysteme in Europa bei [1]. Aufgrund der zentralen Lage in Euro-pa kommt Deutschland und damit dem Netz der Deutschen Bahn sowie seiner Mobilfunkzentrale (MSC) als Drehscheibe für den Quell-, Ziel- und Transitverkehr eine Schlüsselrolle zu (Bild 1).%GSM-R, the digital radio communication system for railways, offers a uniform standard, which more and more railways throughout Europe are using. GSM-R is thus making a crucial contribution to bringing the railway systems closer together. The network operators are already cooperating with one another internationally at various levels in Europe with this aim in mind. The UlC's working groups have drawn up a standardised contract for setting up international roaming, but there are still numerous hurdles to overcome, despite the very considerable volume of work already done. In this context, it would be helpful if certifications of the individual GSM-R networks and their operating methods could be introduced in a binding fashion in accordance with the example laid down ISO 9002. New interfaces between the radio-equipment systems are coming into being at the border crossings between neighbouring infrastructure managers, where there has to be an adequately dimensioned overlapping zone between the networks, and switching from one network to another must be determined independently of the operational constraints of the particular border sections. Thanks to GSM-R, it is becoming possible in many instances to eliminate the communication gaps that have existed to date in handling train movements across borders and thus to make a contribution to the desired improvement in interoperability and operating control. In doing this, it is important above all else for the railway employees to feel at ease working with such systems too.
