Summary:To smoothly switch radio frequencies at which train control information is transmitted and received between a radio mobile station mounted on a train and a plurality of radio base stations disposed along a railway, along which the train moves, in a train control system. In a train control system for performing radio communication between a plurality of mobile stations moving along a predetermined path and a plurality of base stations disposed along the predetermined path, different communication frequencies are assigned to the respective base stations; the mobile stations find the communication frequencies of the base stations disposed along the predetermined path; and the particular radio frequencies found are used to transmit and receive control information between the base stations corresponding to the particular radio frequencies and the mobile stations. La présente invention concerne un procédé permettant de commuter au mieux des radiofréquences auxquelles des données de commande de train sont émises et reçues entre une station mobile installée sur un train et une pluralité de stations de base disposées le long d'une voie ferrée, sur laquelle le train circule, dans un système de commande de train. Dans un système de commande de train qui effectue une radiocommunication entre une pluralité de stations mobiles en déplacement sur un trajet prédéterminé et une pluralité de stations de base disposées le long de ce trajet, différentes fréquences de communication sont attribuées aux stations de base respectives. Les stations mobiles recherchent les fréquences de communication des stations de base disposées le long du trajet prédéterminé, et les radiofréquences trouvées servent à émettre et à recevoir des données de commande entre les stations de base correspondant aux radiofréquences particulières et les stations mobiles.
