<P>PROBLEM TO BE SOLVED: To specify a faulty card by highly precisely detecting the intermittent fault of a card loaded into a base station device with respect to a base station device and a faulty card specifying method. <P>SOLUTION: The base station device is mounted with cards including a call processing control card 101 and baseband processing cards 11, 21. In the base station device, the baseband processing cards 11, 21 are grouped corresponding to a transmission path for an intra-device signal between the baseband processing card 11, 21 and the call processing control card 101. The call processing control card 101 monitors an abnormality of the intra-device signal transmitted from the baseband processing card 11, 21 to the call processing control card 101 and based on the numbers of baseband processing cards 11, 21, each of which has transmitted the intra-device signal with the detected abnormality for each group and packaging position information, a fault position of the card on the transmission path for the intra-device signal is determined. <P>COPYRIGHT: (C)2010,JPO&INPIT |
