Abstract: A method and system that broadcasts different messages into different geographic areas based on the appropriateness, desirability or necessity of broadcasting each messages to each area is disclosed. In particular, the illustrative embodiment of the present invention is a wireless telecommunications system that uses a portion of its spare bandwidth to broadcast messages to the receivers within its domain. The content of the messages can represent advertising, public service announcements, weather and stock reports, etc. One aspect of the illustrative embodiment is that the domain serviced by it is partitioned into a plurality of tessellated areas called “geographic regions.” From a single broadcast server, the various messages to be broadcast are broadcast not to the entire domain of the system, but to only those geographic regions within the domain where the content of those messages is appropriate, necessary or desirable.
