1. A wireless communication system comprising:
a plurality of base stations to which a plurality of terminal stations are connectable; and
a control station that controls each of the base stations,
the control station including:
a network communication unit, including one or more processors, configured to receive, from each of the base stations, base station information indicating the base station, wireless environment information indicating a reception signal received by the base station from another of the base stations and a signal intensity thereof, and terminal station information indicating the terminal station connected to the base station and a signal intensity; and
a calculation unit, including one or more processors, configured to calculate, based on (i) the base station information, (ii) the wireless environment information, and (iii) the terminal station information each received from each of the base stations, connection control information for controlling a connection permission from each of the base stations to each of the terminal stations, wherein the connection control information is calculated so as to cause the base station currently being connected to the terminal station and another of the base stations having an area overlapping that of the base station currently being connected to the terminal station with a signal intensity of not less than a predetermined value to permit connection from the terminal station,
each of the base stations including:
a connection control unit, including one or more processors, configured to control, based on the connection control information, the connection permission to each of the terminal stations.
