Radio communication terminal for optimizing transmission of messages to selective call transceivers and method therefor

A radio communication terminal operating under a frequency reuse plan for communicating to and from a SCT (selective call transceiver) located in any one of a plurality of communication zones corresponding to the frequency reuse plan, comprising:

• a processing system for directing operation of the controller;
• a radio transceiver coupled to the processing system for transmitting and receiving messages from a SCT,
• wherein the processing system is programmed to:
• cause the radio transceiver to receive a registration request when transmitted from the SCT, wherein each SCT transmission occurs as a result of the SCT entering a new communication zone;
• track a history of the SCT's whereabouts according to each registration request received from the SCT;
• receive a message intended for the SCT;
• cause the radio transceiver to transmit the message to the SCT;
• cause the radio transceiver to wait a predetermined time to receive an acknowledgement message from the SCT indicating that the message was received;
• if the acknowledgement message is not received,
• determine from the history of the SCT's whereabouts, one or more most probable communication zones where the SCT may be located;
• and
• cause the radio transceiver to re-transmit the message to the SCT at the one or more most probable communication zones.
