ABSTRACT:
A system and method for communicating with only a subquantity of mobile receivers operating within a geographic area that the sender wishes to communicate with, particularly for time critical messages. A system for geo-casting messages to at least one receiver within a geographic region is provided. The system includes an input for receiving the message and a circuit coupled to the input. Upon receiving the message, the circuit reads a geographic designator. Then the circuit accesses a geospatial database using the geographic designator whereby the circuit determines which receivers are in the geographic region designated by the geographic designator. From the geospatial database, the circuit also determines addresses for the receivers so that the circuit can individually forward the message to the receivers within the designated geographic region.
