PROBLEM TO BE SOLVED: To quicken synchronization with a remote base station by detecting an information channel in addition to the detection of a control channel and adjusting a clock from these detection results. SOLUTION: A control channel(CCH) detection part 13 searches for the CCH of a base station at an interval of 100ms from the detected timing. When the CCH is detected, the clock of the base station and the clock of its own base station are synchronized by recording the receiving timing of the CCH by a 100ms timing measuring part 14, calculating a reception interval and adjusting the interval in a clock adjusting part 17. After the remote base station RBS synchronization by the CCH is established, an information channel (TCH) detection part 15 receives timing information from the 100ms timing measuring part 14. The TCH detection part 15 searches for the synchronizing burst or the TCH burst of the base station at an interval of 5ms from the detected timing and adjusts the clock from the detected results of the CCH and TCH. |
