The object of the invention is to allow two systems residing in the same area and same frequency band to be coexistent compatibly with each other while reducing the mutual interference. A radio network controller 20 for controlling the broadcast timing when various kinds of broadcast information is broadcast with respect to each of two systems, which reside in the same frequency band of the same area and have common specification for physical layer in a state where all or a part of upper layer protocols have no compatibility, broadcasts various kinds of broadcast information about system 1 at a predetermined timing. With respect to various kinds of broadcast information about system 2, broadcast timing information, which is scheduled to be staggered from the broadcast timing of the system 1, is notified using a part of region of the broadcast information, and the broadcast information of the system 2 is broadcast at the notified broadcast timing.
