Method and apparatus in a two-way wireless communication system for location-based message transmission
First Claim
1. A method in a two-way wireless communication system for location-based message transmission, comprising the steps of:
- creating a table for mapping, for ones of a plurality of portable subscriber units, a plurality of message types to a corresponding plurality of locations;
receiving a message matching one of the plurality of message types, the message intended for a portable subscriber unit;
determining a location at which the portable subscriber unit is positioned; and
sending the message to the portable subscriber unit when the location matches one of the plurality of locations corresponding to the one of the plurality of message types.

Abstract
A table (328) is created (402) for mapping, for ones of a plurality of portable subscriber units (122), a plurality of message types to a corresponding plurality of locations. A message matching one of the plurality of message types is then received (404) by a controller (112), the message intended for a portable subscriber unit. In response, the controller and the portable subscriber unit cooperate to determine (406) the location of the portable subscriber unit. The controller sends (428) the message to the portable subscriber unit when the location matches one of the plurality of locations corresponding to the one of the plurality of message types.

17. A portable subscriber unit in a two-way wireless communication system for location-based message transmission, comprising:
-
a receiver for receiving an outbound message; a processing system coupled to the receiver for processing the outbound message; and a transmitter coupled to the processing system for transmitting an inbound message, wherein the processing system is programmed to; cooperate with the receiver to receive a broadcast message specifying a geographic location and a maximum distance; determine, in response to the broadcast message, a location at which the portable subscriber unit is positioned; calculate a distance between the geographic location and the location at which the portable subscriber unit is positioned; and cooperate with the transmitter to transmit information identifying the portable subscriber unit to a fixed portion of the two-way wireless communication system when the distance is less than the maximum distance. - View Dependent Claims (18, 19)
