1. A mobile network control apparatus for energy efficiency, the apparatus comprising:

  • a calculating unit configured to calculate a first amount of total consumed power consumed by m base stations that have a first cell as a coverage area, and configured to calculate a second amount of total consumed power consumed by n base stations that have a second cell including the first cell as a coverage area, where n and m are natural numbers; and

    a processor configured to initiate an operation of the n base stations on a high power mode, and to temporarily suspend an operation of remaining base stations excluding the n base stations, in response to the first amount of total consumed power being greater than the second amount of total consumed power,wherein;

    the calculating unit is further configured to calculate a first result value by multiplying an amount of consumed power that is used for data transmission per unit time in the remaining base stations of which operation is suspended, and an average traffic demand per unit time in terminals located in the first cell, and adding the multiplied result to a base power amount used for initiating an operation of the remaining base stations, and is further configured to calculate a second result value by multiplying an amount of consumed power that is used for data transmission per unit time in the n base stations of which operation is initiated, and an average traffic demand per unit time in the terminals located in the first cell, in response to a number of the terminals located in the first cell being greater than a predetermined number; and

    the processor initiates an operation of the remaining base stations on a low power mode, in response to the first result value being less than the second result value.
