Mobile communication system, and method for controlling channel connection and control station in mobile communication system

A mobile communication system comprising a plurality of wireless base stations to communicate with mobile terminals via wireless channels and a control station connecting to the plurality of wireless base stations to control the plurality of wireless base stations, wherein

• the control station
• regularly collects from the plurality of wireless base stations congestion information of the wireless channels in respective wireless base stations and movement information of mobile terminals;
• prepares schedule information based on statistical processing results of the collected congestion information, the schedule information being used to switch a wireless channel connection control mode of respective wireless base stations;
• and,
• in the case of controlling a wireless base station in a channel congestion avoidance mode according to the prepared schedule information, based on the congestion information of wireless base stations adjacent to the wireless base station and the movement information of the wireless base station, selects a wireless base station as a down channel connection destination from among the adjacent wireless base stations for each mobile terminal currently connected to the wireless base station and for each mobile terminal about to be connected to the wireless base station, notifies each mobile terminal of the selected wireless base station, and controls the wireless base station so that each mobile terminal is connected via a down channel to the selected wireless base station.
