摘要 |
This invention relates to a method and apparatus for warning telephone and wireless customers of a localized emergency condition such as a tornado. The agency responsible for such notification sends a message to an emergency transmission unit. This unit will then cause a warning to be sent to all cellular stations in a plurality of cells defined by the notification message. A similar warning can be sent to land-based stations in the geographic area defined by these cells. Advantageously, the telephone and wireless customers of the affected area can be warned quickly.
