Abstract
Information about usage bandwidths of the ONUs and information about cover areas of the RRHs are acquired. A maximum cover area of each RRH is set. The remaining RRH included in the currently-set cover areas within the maximum cover area of each RRH is identified. The plurality of ONUs, a total usage bandwidth of which is smaller than or equal to an amount of traffic accommodatable by a single ONU, are identified as a sleep candidate ONU group. The ONU and the RRH to be switched to the sleep state are selected. If the maximum cover area of the RRH connected to one of the ONUs included in the sleep candidate ONU group includes a current cover area of the RRH connected to the remaining ONU, the remaining ONU and the RRH connected to them are selected as the ONU and the RRH to be switched to the sleep state.
