WIRELESS COMMUNICATION SYSTEM

摘要

A wireless communication system includes a machine to machine (M2M) device, and a base station that performs wireless communication with the M2M device. The M2M device includes a check-signal transmitting unit that transmits, after a bearer in a wireless section between itself and the base station is released, a check signal to the base station every first period by wireless communication using a frequency that is used in the bearer. The base station includes a determining unit and a notifying unit. The determining unit determines whether there is an abnormality in wireless connection between itself and the M2M device based on whether a check signal is received from the M2M device within a second period. The notifying unit notifies, when the determining unit determines that there is an abnormality in the wireless connection between itself and the M2M device, the abnormality to a predetermined notification destination.
