Method of reliable radio communication network duplication for high speed train and radio communication-based high speed train control system using the same

A radio communication-based high speed train control system comprising:

• a first base station connected to a first base station controller and a second base station adjacent to the first base station connected to a second base station controller different from the first base station controller and a third base station adjacent to the second base station and connected to the first base station controller;
• the base station controllers configured to dispose a directional antennas so that an upper radio cell of the first base station with a lower radio cell of the second base station and an upper radio cell of the second base station with a lower radio cell of the third base station so that the lower radio cells and the upper radio cells can overlap so as to prevent handover delay and disconnection at the interfaces between a plurality of communication network cells;
• a communication network controller connected with the base station controllers and configured to manage a connection between a base station and a radio communication terminal, wherein the radio communication terminal is configured to control a high speed train through a communication network;
• and
• a train system controller connected with the communication network controller and configured to collect railway control information and analyze the collected railway control information.
