PURPOSE:To eliminate an exclusively used control station and to simplify a radio communication system by designating any one base station with a selecting and designating means, which is provided on the base station, when data are transmitted between plural mobile stations and the base station and a line connecting request is given from a mobile station. CONSTITUTION:When the line connecting request is given from the mobile station, such a condition is informed from a slave base station through a route 4 between base stations to a master base station and in the master base station, the arbitrary base station is selected out of the receiving base stations to include the master base station itself. Then, a communication command is outputted to the selected base station and a cancel command is outputted to the other base stations. The base station to receive this communication command connects a line to the mobile station and executes the transmission of radio data and the base station to receive the cancel command becomes a stand-by condition. Here, when a trouble is generated in the master base station, a new master base station is selected out of the base stations and transmitted through a data terminal communication path 5 to the respective base stations. Then, the new master base station is allowed to execute prescribed operation by a communication path 15 between base stations. |
