Claim Text:
1. A renewable energy base station, which is used in a wireless cellular system, comprising: an adjustment request determining part for determining whether an adjustment to a coverage area of the renewable energy base station is required based on at least one of network resource usage information of the renewable energy base station and storage battery electric power information of the renewable energy base station; an adjustment request transceiver, in a case where it is determined that the adjustment to the coverage area of the renewable energy base station is required, sending a coverage area adjustment request to neighboring base stations in the wireless cellular system, and receiving an adjustment request response from one or more of the neighboring base stations; an adjustment request responding part for determining whether the coverage area adjustment request from the one or more of the neighboring base stations is allowed based on at least one of the network resource usage information and the storage battery electric power information of the renewable energy base station in a case where receiving the coverage area adjustment request from one of the neighboring base stations; and a response transmitter for sending the adjustment request response to the neighboring base stations based on a result of the determination made by the adjustment request responding part, wherein the network resource usage information includes information indicating a used amount of a network resource of the renewable energy base station, and the storage battery electric power information includes information indicating a remaining electric power of the storage battery of the renewable energy base station, and in a case where the used amount of the network resource of the renewable energy base station is less than a predetermined first threshold value and the remaining electric power of the storage battery of the renewable energy base station is greater than a predetermined second threshold value, the adjustment request responding part determines that the coverage area adjustment request from the one of neighboring base stations is allowed.
