PROBLEM TO BE SOLVED: To provide a communication system for filtering multi-destination messages.SOLUTION: The communication system includes a number of transmitters, an interface, a first filter, and a second filter. The number of transmitters send information wirelessly to a number of wireless terminals. The interface receives messages intended for at least some of the number of wireless terminals, where the number of wireless terminals include a wireless terminal. The first filter determines a subset of the number of transmitters that generally correspond to predetermined geographic criteria, where the subset transmits a message. The second filter determines if the wireless terminal corresponds to the predetermined geographic criteria. |
