<p><P>PROBLEM TO BE SOLVED: To obtain a wireless base station apparatus increasing the success rate of reference clock correction. <P>SOLUTION: The device includes: a memory part 2 for storing time data obtained from a time server and determination results of whether the time data can be used for reference clock correction or not; a time data obtaining part 1 for requiring the time server to provide the time data, and storing in the memory part 2 the time data obtained as response of the requiring; a time data determination part 3 for determining whether the time data stored in the memory part 2 can be used for reference clock correction or not, and storing in the memory part 2 the determination results associated with the time data; and a correction control part 4 for reading latest time data obtained from the same time server and time data obtained in the past, out of the usable time data stored in the memory part 2, and correcting the reference clock based on the read data. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
