1. A wireless communication system comprising:
a base station to which a plurality of terminal stations are connectable; and
a control station configured to control the base station,
the base station including one or more processors configured to:
collect terminal station information indicating terminal stations each having issued a connection request to the base station;
cause a storage unit to store connected terminal station information indicating, among the terminal stations indicated by the terminal station information, the terminal station currently being connected to the base station;
receive, from the control station, base station control information for controlling a response to the connection request from the terminal station that is not indicated by the connected terminal station information; and
determine, based on each of the connected terminal station information and the base station control information, whether or not the connection request from the terminal station that is not indicated by the connected terminal station information is to be refused,
the control station is configured to:
transmit, when a predetermined condition is satisfied, to the base station, the base station control information indicating that the connection request from the terminal station that is not indicated by the connected terminal station information is to be refused; and
transmit, to the base station, the base station control information indicating that the terminal station that has issued the connection requests the number of which is not less than a predetermined number within a predetermined period is to be permitted to be connected even when the terminal station is not indicated by the connected terminal station information.
