<P>PROBLEM TO BE SOLVED: To prevent operation efficiency from becoming low by speedily performing resynchronization without causing a stop of communication service when it becomes impossible to maintain frame synchronism between base station devices. <P>SOLUTION: A synchronism monitor part 218 instructs a timing detection part 212 to periodically or abruptly monitor frame synchronism with other base station devices. The timing detection part 212 discretely detect reference timing from a signal received from an external base station device through a wireless part 204. A synchronizing signal generation part 214 continuously generates internal timing based upon the reference timing that the timing detection part 212 discretely detects. A synchronism control part 214 corrects the internal timing to make an error between the reference timing and the continuously generated internal timing smaller in steps and generates internal timing to synchronize with the reference timing of the external base station device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
