ABSTRACT:
Geographic information may be automatically transmitted to communication units (102, 103) by a communication resource controller (101). The communication resource controller (101) upon receiving location coordinates, accesses a data base (124) to determine localized geographic dependent information. Having retrieved this information, the communication resource controller (101) transmits this information to the communication units (102, 103). Upon receipt of this information, the communication units (102, 103) determine whether it is pertinent to them. If the information is pertinent, the communication units (102, 103) display the information.
