notifying a wireless terminal of an active prohibition time in which a change to an active state, in which the wireless terminal and the wireless base station are ready to start a communication in the estimated time period, is prohibited, and of a dormant prohibition time in which a change to a dormant state, in which the wireless line is released and a logical connection between the wireless terminal and the wireless base station is maintained, is prohibited; changing a connection state between the wireless terminal and the wireless base station to the active state when a current time enters the estimated time period and is other than the active prohibition time; changing the connection state to the dormant state when the current time enters the estimated time period and the current time is the active prohibition time and is other than the dormant prohibition time; and changing the connection state to a null state in which the wireless line is released and the logical connection is disconnected when the current time enters the estimated time period and the current time is the active prohibition time and is the dormant prohibition time. ### Claim 7 (depends on 3) The communication controlling method according to claim 3, wherein a wireless line is selected from among wireless lines in which the wireless terminal and the wireless base station are not in communication but which are in the active state, and a connection state of the selected wireless line is changed from the active state to the dormant state, when the number of wireless lines in the active state exceeds a predetermined number. ### Claim 8 (depends on 7) The communication controlling method according to claim 7, wherein the selected wireless line is a wireless line used by an application with a lowest priority among applications using the wireless line. ### Claim 9 (depends on 7) The communication controlling method according to claim 7, wherein the selected wireless line is a wireless line of which a telephone number is not a telephone number to be connected with high priority. ### Claim 10 A method for sharing control information with a wireless base station and a wireless terminal, the method comprising: notifying, from the wireless base station to a wireless base station controlling apparatus managing the control information, an active prohibition time that prohibits an active state in which the wireless line is occupied, a dormant prohibition time that prohibits a dormant state in which the occupied wireless line is released and a logical connection between the wireless terminal and the wireless base station is maintained, and position information of the wireless base station, as the control information;
