Abstract
An interruption cause determination device comprising: acquiring in the memory a radio wave reception strength (RWRS) and a packet error rate (PRE) of a wireless link, and estimating a characteristic curve of the PRE against RWRS that passes through a point corresponding to a combination of values of the RWRS and the PRE at a first point in time a specific amount of time earlier than a second point in time at which the acquired PRE of the wireless link reached a threshold value or greater, under the assumption that the interference power at the first point in time is maintained; and determining the cause of interruption based on a positional relationship of a point corresponding to a combination of values of the RWRS and the PRE at the second point in time, with respect to the estimated characteristic curve of the PRE against RWRS.
