[Problem] Provided is a scheme such that it is possible to efficiently perform signaling for controlling the operation mode of a small cell in an environment in which a plurality of small cells are disposed. [Solution] Provided is a communication control device provided with: a communication unit that communicates with each communication node operating a plurality of small cells each belonging to at least one of a plurality of small cell groups; a determination unit that, in units of small cell groups, determines whether to set the respective operation modes of the plurality of small cells to an active mode; and a signaling unit that signals, to the communication nodes via the communication unit, a control message for specifying the operation mode of units of the small cell groups as determined by the determination unit.
