The purpose of the present invention is to provide, in the context of the operation of base station devices defined under 3GPP specifications, an alert distribution device that sends an alert to a device as appropriate on the basis of prescribed conditions, without the alert precedingly requested for distribution being overwritten by the alert succeedingly requested for distribution. To achieve this purpose, an assessment is made when distributing a new alert on whether to delay distributing the new alert on the basis of attributes of alerts distributed in the past, and if the assessment is in favor of delaying distribution, the new alert is distributed after a delay of a prescribed length to the base station device that sends new alerts to terminal devices in place of alerts requested for distribution in the past.
