Abstract
A computer obtains a first packet group transmitted wirelessly by a first wireless communication apparatus and a second packet group transmitted wirelessly by a second wireless communication apparatus. The computer then detects a first non-communication period, during which there are no packets transmitted by the first wireless communication apparatus for a prescribed time or longer, and also detects a second non-communication period, during which there are no packets transmitted by the second wireless communication apparatus for the prescribed time or longer. The computer then determines based on an overlap between the first and second non-communication periods whether the first and second wireless communication apparatuses are connected to the same wireless base station.
