A wireless communication system includes: a mobile station; a first base station that communicates with the mobile station; and a second base station that communicates with the mobile station. The mobile station includes a measuring unit, a calculating unit, and a sending unit. The measuring unit measures a location of the mobile station. The calculating unit calculates, by using location information measured by the measuring unit and location information on the first base station, a distance between the mobile station and the first base station. The sending unit sends, to the second base station based on the distance calculated by the calculating unit and a predetermined threshold, a request signal that is used to request setting of a channel between the second base station and the first base station.
