1. A communication control device comprising: a monitoring unit that monitors a traffic amount between a server that downloads data to a plurality of mobile stations and a base station; a number calculation unit that calculates a number of steps of a value that serves as a reference for determining a mobile station of a download destination of the data based on a monitoring result by the monitoring unit; a value calculation unit that calculates the value for each mobile station using the number of steps calculated by the number calculation unit and radio communication quality of the plurality of mobile stations; a determination unit that determines the mobile station of a download destination in order from a mobile station in which the value at a first timing is higher, the value being calculated by the value calculation unit; and a control unit that downloads the data to the mobile station determined as the download destination by the determination unit, wherein the number calculation unit calculates a number of ranks according to a rate of traffic to be decreased and a threshold value based on a predetermined calculation formula, wherein the number calculation unit calculates threshold values that are boundary values of a plurality of the values for each mobile station using a maximum value and a minimum value of the radio communication quality of the plurality of mobile stations at a predetermined time and the number of steps and the value calculation unit calculates the value for each mobile station based on whether the radio communication quality of each mobile station is equal to or more than the threshold value calculated by the number calculation unit, wherein the maximum value is a maximum value of a Signal to Interference Ratio (SIR) of a corresponding mobile station in a past predetermined time and the minimum value is a minimum value of the Signal to Interference Ratio (SIR) of the corresponding mobile station in the past predetermined time.
