Abstract: PURPOSE: A communication quality information supplying method on a network of railroads is provided to rapidly supply wireless communication quality information to a manager. CONSTITUTION: A DM(Device Management) server(400) receives wireless quality information from a ground communication device(200). The DM server updates wireless quality information received from a vehicle device(100) in quality information database. The DM server receives a request of wireless quality information from a communication terminal of a requester. The DM server searches for wireless quality information in the quality information database. The DM server supplies the searched wireless quality information to a communication terminal.
