Abstract
Communications may be established based on geographic location when a communication resource controller (101) transmits a communication message (119), which includes a message ID (120) a communication payload (121), and a set of geographic coordinates to a plurality of communication units (102, 103). Each of communication units (102, 103) upon receiving the communication message (119), compares its identification code (123) with the message ID (120). If a match occurs, the communication unit (102, 103) then determines its geographic location. Having obtained the geographic location, the unit determines whether its present location is within the area defined by the set of geographic coordinates and, if so, adjust its receiver to receive the communication payload (121).
