Step 102: when the train is determined to drive out of the coverage area of the private network cell, sequentially deactivating control channels of M private network single cells;
here, when determining that the train is driven out of the coverage area of the private network cell, the following steps are performed: when the time that the train drives into the private network cell exceeds the preset second protection time, namely when the train drives out of the first private network cell which is driven into the private network cell;
