Abstract

A base station 10 is provided with a battery 12 and is capable of being driven by power supplied from the battery 12, comprises: a network communication unit 132 configured to transmit remaining power amount information indicating a remaining power amount of the battery 12 to another base station; and a communication control unit 171 configured to control the transmission of the remaining power amount information to the other base station in accordance with the remaining power amount of the battery.

Claims

1. A communication control method in a mobile communication system that includes abase station that is provided with a battery and that is capable of being driven by power supplied from the battery, comprising:

a transmission control step of controlling, by the base station, transmission of remaining power amount information from the base station to another base station, wherein

the remaining power amount information indicates a remaining power amount of the battery, and

the transmission control step controls the transmission of the remaining power amount information from the base station to the other base station in accordance with the remaining power amount of the battery.

2. The communication control method according to claim 1, wherein

the transmission control step comprises:

a step of controlling so as to transmit the remaining power amount information to the other base station when the remaining power amount of the battery is equal to or more than a first threshold value; and

a step of controlling so as not to transmit the remaining power amount information to the other base station when the remaining power amount of the battery is less than the first threshold value.

3. The communication control method according to claim 2, further comprising:

a reception step of receiving, by the other base station, the remaining power amount information from the base station; and

a load adjustment step of performing, by the other base station, a process for increasing a load of the base station and for decreasing a load of the other base station when a remaining power amount of a battery provided in the other base station is less than the remaining power amount indicated by the remaining power amount information received in the reception step.

4. The communication control method according to claim 1, wherein

the transmission control step comprises:

a step of controlling so as to transmit the remaining power amount information to the other base station when the remaining power amount of the battery is less than a second threshold value; and

a step of controlling so as not to transmit the remaining power amount information to the other base station when the remaining power amount of the battery is equal to or more than the second threshold value.

5. The communication control method according to claim 4, further comprising:

a reception step of receiving, by the other base station, the remaining power amount information from the base station; and

a load adjustment step of performing, by the other base station, a process for decreasing a load of the base station and for increasing a load of the other base station when a remaining power amount of a battery provided in the other base station is more than the remaining power amount indicated by the remaining power amount information received in the reception step.

6. A base station that is provided with a battery and capable of being driven by power supplied from the battery, comprising:

a transmission unit configured to transmit remaining power amount information indicating a remaining power amount of the battery to another base station; and

a control unit configured to control the transmission of the remaining power amount information to the other base station in accordance with the remaining power amount of the battery.
