摘要：The present invention is designed to establish synchronization properly evenwhen synchronizing between different cells by means of a radio interface in anasynchronous NW. A radio base station establishes radio synchronization by usingdownlink signals transmitted from the radio base station of other cells, and has asynchronization information control section that, via an inter-base station interface,reports a synchronization information request to the radio base stations of other cellsand also acquires synchronization information reported from the radio base stations ofother cells, and a determining section that determines a radio base station to establishradio synchronization with, based on the synchronization information acquired, and thesynchronization information which the synchronization information control sectionacquires from the radio base stations of other cells includes the synchronization status,the synchronization stratum levels, and information to represent the synchronizationgroups, of the radio base stations of other cells.
