PROBLEM TO BE SOLVED: To reduce a probability of a mobile station device used for a mobile communication system adopting the TDM/TDMA system that is synchronized with other word than an original synchronizing word during channel switching from a control channel to a communication channel. SOLUTION: Aftar detecting a synchronizing word of a channel designated by its own station by a mobile station device in the case of synchronization to a communication channel (step S11), a synchronizing word at other channel is detected in a timing estimated for its presence on the same carrier (gaps S12-S14) so as to reduce probability of mis-synchronization. |
