The invention provides a method for controlling movement authorization of a train. The method comprises the steps that when a radio blocking center (RBC) determines that a block section occupancy (oranomaly) occurs within a driving permission range which is sent to the train by the radio blocking center, and the occupied (or abnormal) block section is not an adjacent block section of the block section where the train is located, at the moment, the RBC sends a conditional emergency stop message(CEM) to the train; after the train receives the CEM, the train determines whether or not the currentposition where the train is located is beyond an emergency stop position according to emergency stop position information in the CEM, whether or not to execute the CEM is determined according to a determination result. According to the method for controlling the movement authorization of the train, by determining whether or not the current position where the train is located is beyond the emergency stop position and determining whether or not to execute the CEM according to the determination result, the situation that an emergency braking is conducted on the train to make the train stop due to the fact that the train is running at a high speed or position report intervals are big is avoided.
