1. A communication control apparatus, comprising:

  • a radio communication unit configured to provide a second radio communication service within a cell in which a base station provides a first radio communication service; and

    a control unit configured to;

    determine that a communication quality of the first radio communication service exceeds a determined threshold quality;

    switch an operation mode of the radio communication unit from a first mode to a second mode based on the determination that the communication quality of the first radio communication service exceeds the determined threshold quality, whereinin the first mode, the radio communication unit is configured to operate continuously,in the second mode, the radio communication unit is configured to operate intermittently,the operation mode is switched after stepwise reduction of transmission power of a reference signal transmitted from the radio communication unit,the stepwise reduction of the transmission power corresponds to reduction of the transmission power in a plurality of steps; and

    stand by for a specific time period after each step of the plurality of steps, whereinthe specific time period is a time period required for a terminal apparatus connected to the second radio communication service to switch a connection destination,a power consumed in the second mode is less than a power consumed in the first mode,a plurality of component carriers includes first component carriers used in the second mode and second component carriers used in the first mode, anda count of the first component carriers is less than a count of the second component carriers.
