Patent ID: 7536170

Claim:
A method comprising: identifying one or more mobile stations registered within a service area of a wireless communication system, the mobile stations potentially comprising Improvised Explosive Device (IED) triggering devices; and transmitting, from a stationary platform, one or more directionalized, low power alerting signals to the mobile stations within a portion of the service area defining an IED detonation zone, thereby alerting the mobile stations including any IED triggering devices within the IED detonation zone, the IED detonation zone defining the portion of the service area in which the mobile stations can receive the alerting signals; performed by a wireless terminal defining a directionalized local cellular alerting transmitter (DLCAT) residing at the stationary platform, where the DLCAT is not part of a telecommunication infrastructure system with which the mobile stations have subscribed for wireless communication services, the alerting signals transmitted by the DLCAT are directory number specific signals associated with respective mobile stations within the IED detonation zone. wherein the directionalized, low power alerting signals have a power low enough such that only mobile stations within the IED detonation zone will receive the alerting signals so that any mobile stations outside the IED detonation zone will not receive the alerting signals.
