Abstract
A communications system provides subfleet calls for both voice and data communications using a secondary identification (301, 303, 305, 307, 309) incorporating a plurality of subfleets in a hierarchical arrangement. A message including the secondary identification (301, 303, 305, 307, 309) is transmitted to a communication unit (117) having a stored secondary identification (301, 303, 305, 307, 309). If the transmitted secondary identification sufficiently matches the stored secondary identification, the communication unit (117) responds to the instructions in the transmitted message.
Claims19
A method for providing subfleet transmissions in a communication system, comprising the steps of:
- storing a secondary identification, wherein said secondary identification comprises a plurality of subfleets in a hierarchical arrangement and wherein said secondary identification reflects the hierarchial arrangement of said plurality of subfleets;
- receiving a subfleet data transmission including a variable identification, said second identification and a command to store said variable identification;
- storing said variable identification;
- and
- responding to a subsequent subfleet data transmission only when said subsequent subfleet data transmission includes one of said stored variable identification and said stored secondary identification.
A method for providing transmissions to at least two subfleets in a communication system with a plurality of communication units, comprising the steps of:
- identifying at least two desired subfleets for a subfleet data transmission;
- transmitting, responsive to said identifying step, a message to each of said at least two desired subfleets, said message incorporating a secondary identification pertaining to one of said at least two desired subfleets, wherein said secondary identification comprises a plurality of subfleets in a hierarchical arrangement;
- transmitting with said messages to each of said at least two desired subfleets a variable identification and a command to store said variable identification;
- receiving and storing said variable identification at a communication unit;
- and
- responding, by said communication unit, to a subsequent subfleet data transmission only when said subsequent subfleet data transmission includes one of said variable identification and said secondary identification stored in said communication unit.
A method for providing transmissions to at least two subfleets in a communication system with a plurality of communication units, comprising the steps of:
- identifying at least two desired subfleets for a subfleet voice transmission;
- transmitting, responsive to said identifying step, a message to each of said at least two desired subfleets, said message incorporating a secondary identification pertaining to one of said at least two desired subfleets, wherein said secondary identification comprises a plurality of subfleets in a hierarchical arrangement;
- transmitting with said messages to each of said at least two desired subfleets a variable identification and a command to store said variable identification;
- receiving and storing said variable identification in a communication unit;
- transmitting a third message with said variable identification and a command to go to a voice channel;
- transmitting said subfleet voice transmission on said voice channel;
- receiving said third message and said subfleet voice transmission at said communication unit;
- and
- responding, by said communication unit, to said subfleet voice transmission only when said subfleet voice transmission includes one of said variable identification and said secondary identification stored in said communication unit and tuning to said voice channel without operator intervention.
A communication unit able to receive subfleet transmissions in a communication system, the communication unit comprising:
- means for storing a secondary identification, wherein said secondary identification comprises a plurality of subfleets in a hierarchical arrangement and wherein said secondary identification reflects the hierarchial arrangement of said plurality of subfleets;
- means for receiving a subfleet data transmission including a variable identification, said second identification and a command to store said variable identification;
- means for storing said variable identification;
- and
- means for responding to a subsequent subfleet data transmission only when said subsequent subfleet data transmission includes one of said stored variable identification and said stored secondary identification.
