Patent ID: 8824972

Claim:
A radio station connected to another radio station via a radio link and identifying a fault of the radio link, comprising: a radio link controlling unit configured to execute radio link control of the radio link in accordance with a radio link control scheme: a statistical information acquiring unit configured to acquire statistical information indicating a state of the radio link during the execution of the radio link control: and a fault identifying unit configured to identify the fault of the radio link from among a plurality of faults associated with statistical information, on the basis of the statistical information acquired by the statistical information acquiring unit, wherein the radio link control scheme includes at least two of: a scheme 1 in which communication with the another radio station is stopped; a scheme 2 in which communication by a different radio station using same channel as that used by the another radio station is stopped; a scheme 3 in which communication by a different radio station using a channel adjacent to the channel used by the another radio station is stopped; a scheme 4 in which communication by a different radio station using same channel as that used by the another radio station is stopped, and a test frame is transmitted to the another radio station; and a scheme 5 in which communication by a different radio station using same channel as that used by the another radio station is stopped, and a test frame is transmitted to the another radio station at a lower rate than a rate of the scheme 4, wherein, the statistical information and the faults are associated for each of the schemes 1 to 5, the radio link controlling unit is configured to execute the radio link control of the radio link in accordance with each of the at least two of schemes 1-5 and the fault identifying unit identifies the fault according to one that has been executed among the at least two of schemes 1-5 and the statistical information acquired by the statistical information acquiring unit during the execution of the radio link control of the one scheme.
