<p><P>PROBLEM TO BE SOLVED: To identify a mobile station having transmitted an access signal, in order to suppress erroneous detection of an access signal transmitted from the mobile station. <P>SOLUTION: The mobile station transmits an access signal. A detection determination unit within a wireless base station obtains and compares: a first difference between the reception timing of the access signal received last time and a processing reference timing; and the second difference between the reception timing of the access signal received this time and the processing reference timing. In accordance with the result of the comparison, the mobile station is identified. With respect to the access signal transmitted from the identified mobile station, it is determined that the access signal is detected, in accordance with the number of times of consecutive reception of an access signal exceeding a threshold level. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
