Abstract
A base station communicates with a mobile station. The base station includes a wireless communication unit and a control unit. The wireless communication unit transmits an alert periodically to the mobile station using a first channel, receives, from the mobile station, alert reception information related to reception of the alert, and transmits at least a part of the alert to the mobile station using a second channel different from the first channel. The control unit instructs the wireless communication unit, in response to the alert reception information, to transmit to the mobile station at least a part of the alert using the second channel.
