Provided is a base station capable of maintaining a communication quality of a communication terminal (mobile station) having registered its position with the base station itself, even if an operating frequency is changed. According to the present invention, the base station includes a transmission and reception unit 102 configured to transmit and receive signals at the operating frequency for communication with the communication terminal, a pilot beacon transmission unit 104 configured to transmit a pilot beacon to a communication terminal, in communication with another base station, at an operating frequency of the another base station in order to allow the communication terminal to detect the operating frequency of the base station itself, and a control unit 101, if changing the operating frequency of the transmission and reception unit 102, configured to control the pilot beacon transmission unit 104 to change the frequency of the pilot beacon to transmit therefrom to the operating frequency of the transmission and reception unit 103 before changed and transmit the pilot beacon at this frequency. |
