<p><P>PROBLEM TO BE SOLVED: To provide a radio base station, an inter-radio base station synchronization control center, and a synchronization control method for an inter-radio base station synchronization control system, enabling restoration of frame synchronization when the frame synchronization fails. <P>SOLUTION: A frame synchronization controller 33 synchronizes a frame of the self-station with a reference signal from a GPS antenna 30. A communication state information generator 21 generates communication state information representing the communication state of the self-station, so as to transmit to the inter-radio base station synchronization control center 1. A frame resynchronization controller 3 decides whether frame resynchronization is required in each radio station based on the received communication state information of each radio base station, and transmits an instruction for frame resynchronization to the radio base station in which the frame resynchronization is required. On receipt of the instruction for frame resynchronization, a frame synchronization controller 33 performs frame synchronization of the self-station again. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
