Position determination timing selection device, wireless communication system, position determination timing selection method, and recording medium

Abstract

Channel identification information indicating a channel measured by each of a plurality of measurement devices that measure a radio wave strength of radio waves propagating in the channel used by a wireless terminal device for radio wave transmission, and information indicating a measurement time at which the measurement was performed are acquired. For each channel, a time at which number of the measurement devices performing measurement satisfies a predetermined condition defined in advance is selected based on the acquired channel identification information of each measurement device and the information indicating the measurement time. A position determination time for each channel from each selected time is selected, and the channel identification information indicating the channel used by the wireless terminal device subject to position determination is acquired.
