1. A base station that communicates with a mobile station by using radio signals, comprising:

  • a storage unit for storing a predetermined number of base station information, each including a base station ID for discriminating a specific base station and parameter information for radio communications set for the specific base station;

    an acquisition unit for acquiring base station IDs of base stations forming destination cells of the mobile station, or base station IDs of base stations forming source cells of the mobile station during a first time period;

    an aggregating unit for aggregating a number of times that each of the base station IDs is acquired by the acquisition unit;

    a determination unit for determining a priority of each of the base station IDs on a basis of the aggregated results obtained by the acquisition unit;

    a judging unit for judging among the base station IDs whose acquisition numbers are aggregated whether or not there is a base station ID having a priority higher than the base station ID stored in the storage, and whose acquisition number is larger than a predetermined number of times; and

    a manager for deleting, from the storage, a base station information including a base station ID having a priority lower than a base station ID judged to have a higher priority, and to store, in the storage, a base station information including the base station ID judged to have a higher priority, in a case where the judging unit judges there is a base station ID having a higher priority than the base station ID stored in the storage and whose acquisition number is larger.
