Abstract
The connection state of a wireless line, in which a communication can be immediately made in an estimated time period, is preset by estimating the time period with a high possibility of making a communication based on the communication history of a wireless terminal for a predetermined past period in a communication made between the wireless terminal and a wireless base station.
Claims17
A communication controlling method for controlling a communication using a wireless line between a wireless terminal and a wireless base station, the communication controlling method comprising:
- estimating, using a communication history of the wireless terminal for a predetermined past period, a time period with a high frequency of making communications;
- and
- changing a connection state between the wireless terminal and the wireless base station to a connection state in which a wireless line is occupied for the wireless terminal to allow starting of a communication using the occupied wireless line in the time period with a high frequency of making a communication.
A communication controlling method for controlling a communication using a wireless line between a wireless terminal and a wireless base station, the communication controlling method comprising:
- estimating, using a communication history of the wireless terminal for a predetermined past period, a time period with a high frequency of making communications;
- 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.
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;
- respectively notifying, by the wireless base station controlling apparatus, wireless base stations of control information received from the wireless base stations;
- and
- notifying, by the wireless base station, a wireless terminal connectable to the wireless base station of the control information received from the wireless base station controlling apparatus.
A non-transitory storage medium having stored therein a program for causing a wireless terminal to execute a process for controlling a communication using a wireless line between the wireless terminal and a wireless base station, the process comprising:
- estimating, using a communication history of the wireless terminal for a predetermined past period, a time period with a high frequency of making communications;
- and
- changing a connection state between the wireless terminal and the wireless base station to a connection state in which a wireless line is occupied for the wireless terminal to allow starting of a communication using the occupied wireless line in the estimated time period.
A recording medium having stored therein a program for causing a wireless base station to execute a process for controlling a communication using a wireless line between a wireless terminal and the wireless base station, the process comprising:
- selecting a wireless line from among wireless lines in which the wireless terminal and the wireless base station are not in communication but which are in an active state in which a wireless line is occupied for the wireless terminal to allow starting of a communication using the occupied wireless line, and changing a connection state of the selected wireless line from the active state to 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, when the number of wireless lines in an active state exceeds a predetermined number;
- and
- selecting a wireless line from among wireless lines in which the wireless terminal and the wireless base station are not in communication but which are in the dormant state, and changing a connection state of the selected wireless line from the dormant state to a null state in which the occupied wireless line is released and a logical connection is disconnected, when the number of wireless lines in a dormant state exceeds a predetermined number.
A wireless terminal making a communication with a wireless base station using a wireless line, the wireless terminal comprising:
- a time period estimating unit to estimate, using a communication history of the wireless terminal for a predetermined past period, a time period with a high frequency of making communications;
- and
- a communication controller to change a connection state between the wireless terminal and the wireless base station to a connection state in which a wireless line is occupied for the wireless terminal to allow starting of a communication using the occupied wireless line in the estimated time period.
A wireless base station making a communication with a wireless terminal using a wireless line, the wireless base station comprising
- a line selector to select a wireless line from among wireless lines in which the wireless terminal and the wireless base station are not in communication but which are in use and to change a connection state of the selected wireless line to a state other than the connection state, when the number of wireless lines in use exceeds a predetermined number.
A wireless base station controlling apparatus managing information about a wireless base station which makes a communication with a wireless terminal using a wireless line, the wireless base station comprising:
- a receiver to receive, from the wireless base station, an active prohibition time that prohibits an active state in which the wireless line is occupied for the wireless terminal to allow starting of a communication using the occupied wireless line, 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 control information;
- and
- a notifying unit to respectively notify wireless base stations of control information received from the wireless base stations.
