SOME SIGNAL PROPAGATION AND TRAFFIC HANDOVER ASPECTS OF A MOBILE RADIO NETWORK FOR HIGH-SPEED RAILWAYS

Taking advantage of GSM's elaborated mobility management and international roaming capability, the International Union of European Railroad Operators (UIC) has decided to build a supra-national rail radio network based on enhanced GSM technology. In this paper, some implementation aspects specific to the railroad radio environment resulting from the effects of vehicle speed--in particular, Doppler shifting--are discussed, and an "off-line" algorithm for the traffic handover is proposed. This algorithm offers better radio link reliability and less critical timing constraints than conventional handover schemes. More reliable handover is of vital importance in the case of high-speed trains because the radio link is intended to carry the automatic control signals as well.
