(54) Base station device, control method of base station device and control program of base station device


(57) In the case where two base stations (CS1, CS2) are cascaded by a signal line (20) for ensuring more information channels, if traffic increases in the base station on a master side, it can be considered that communication conditions of the base station on the master side are better than those of the base station on a slave side at that point in time. Sending of the control channel is switched between one and the other of the cascaded two base stations depending on the situations at that point in time, and therefore the base station providing good communication conditions can perform the communication with a mobile terminal to a larger extent so that the communication can be stable. Users can easily perform outgoing and incoming calls with respect to the base station. A base station, which can accommodate more users and can offer 64-kpbs service with an improved probability, is provided.
