CONTROL APPARATUS, CONTROL METHOD, AND PROGRAM
A control apparatus that controls a base station in a mobile communication system including multiple base stations includes a suspension station determination unit configured to determine, based on a traffic demand of each of the base stations, a suspension station that suspends at least one frequency band and a parameter of at least one repair station that covers a coverage hole generated by the suspension of the suspension station; and a control transmission unit configured to transmit control information, the control information including information on the suspension station determined by the suspension station determination unit and the parameter.
1 . A control apparatus that controls a base station in a mobile communication system including a plurality of base stations, the control apparatus comprising:
processing circuitry configured to
determine, based on a traffic demand of each of the base stations, a suspension station that suspends at least one frequency band and a parameter of at least one repair station that covers a coverage hole generated by the suspension of the suspension station; and
transmit control information, the control information including information on the determined suspension station and the parameter.
2 . The control apparatus according to claim 1 , wherein
the processing circuitry is further configured to determine a parameter of the at least one repair station corresponding to a situation in which a number of frequency bands suspendable by the suspension station is the largest among situations in which the at least one repair station is able to cover the coverage hole.
3 . The control apparatus according to claim 1 , wherein
the processing circuitry is further configured to determine a base station in which no coverage hole is generated even when all frequency bands are suspended as a suspension station that does not require a parameter change of a peripheral station.
4 . The control apparatus according to claim 1 , wherein
the processing circuitry is further configured to determine whether to restart the suspended at least one frequency band in the suspension station based on the traffic demand.
5 . The control apparatus according to claim 1 , wherein
the processing circuitry is further configured to
determine the control information for each of a plurality of time zones in future based on a prediction value of a future traffic demand, and
the control information when a time of said each of the time zones arrives.
6 . A control method executed by a control apparatus that controls a base station in a mobile communication system including a plurality of base stations, the control method comprising:
determining, based on a traffic demand of each of the base stations, a suspension station that suspends at least one frequency band and a parameter of at least one repair station that covers a coverage hole generated by the suspension of the suspension station; and
transmitting control information, the control information including information on the determined suspension station and the parameter.
7 . A non-transitory computer-readable recording medium storing a program for causing a computer to execute a process, the process including:
determining, based on a traffic demand of each of the base stations, a suspension station that suspends at least one frequency band and a parameter of at least one repair station that covers a coverage bole generated by the suspension of the suspension station; and
transmitting control information, the control information including information on the determined suspension station and the parameter.
