Method of communicating emergency warnings through an existing cellular communication network, and system for communicating such warnings
First Claim
1. A method of communicating emergency warnings to persons within a selected geographic area within a geographic region served by an existing cellular communication system that comprises a plurality of signal transmission stations, the method comprising:
- providing a plurality of warning devices within the geographic region;
identifying one or more, but less than all, of the plurality of transmission stations in the cellular communication system appropriate to activate warning devices in the geographic area; and
transmitting a predetermined signal from the identified transmission station or stations to activate all the active warning devices in the geographic area of the geographic region, which warning devices generate emergency warnings in response to the predetermined signal.

Abstract
A method of communicating emergency warnings to persons within a selected in a region served by a cellular communication system that comprises a plurality of transmission stations, includes providing persons in the area with warning devices that generate an emergency warning in response to a predetermined signal; identifying at least one transmission station in the communication system to transmit the predetermined signal to warning devices in the selected area; and transmitting the predetermined signal from the identified transmission station to cause warning devices in the selected area to generate emergency warnings. The system for implementing this method includes a plurality of warning devices disbursed throughout the area, and a device for identifying one or more signal transmission stations in the cellular communication network appropriate to transmit the predetermined signal to warning devices in the selected area, and causing the transmission stations identified to transmit the predetermined signal to cause warning devices in the selected geographic area to generate emergency warnings.
