Claim 1
Independent Claim
120 words
A method of transmitting message information from an initiating unit to a destination unit over a time division multiple access (TDMA) mobile radio network having a plurality of mobile units, each with a unique internal identification (ID) number, comprising the steps of: a) determining a destination unit identification number (ID) for said destination unit desired to receive information packet; b) creating a message packet having a message ID, the destination unit ID, and said message information; c) determining a time slot assigned to said initiating unit; d) broadcasting the message packet to recipient mobile units in a non-interfering fashion at a time period other than that assigned to said initiating unit; e) for each recipient mobile unit receiving the broadcast:
Claim 2
Independent Claim
120 words
A method of transmitting message information from an initiating unit to a destination unit over a time division multiple access (TDMA) mobile radio network having a plurality of mobile units, each with a unique internal identification (ID) number, comprising the steps of: a) determining a destination unit identification number (ID) for said destination unit desired to receive information packet; b) creating a message packet having a message ID, the destination unit ID, and said message information; c) determining a time slot assigned to said initiating unit; d) broadcasting the message packet to recipient mobile units in a non-interfering fashion at a time period other than that assigned to said initiating unit; e) for each recipient mobile unit receiving the broadcast:
Claim 3
Dependent Claim
156 words
checking for errors in the received message packet, and transmitting an ackowledgment signal if received with no errors, 2. identifying if the message is a valid message packet, a valid message packet being one which was received without errors, has not expired and is has an message ID which does not match stored message IDs, 3. comparing the destination unit ID to the intemal ID of the recipient mobile unit for the message if it is a valid message packet, 4. storing and utilizing valid message packets which the destination unit ID matches the intemal ID of the recipient mobile unit, 5. determining a time slot assigned to this recipient mobile unit if the message is a valid message packet, and 6. re-broadcasting the message packet to other recipient mobile units in a non-interfering fashion at a time period other than that assigned to this recipient mobile unit if the message is a valid message packet.
Claim 4
Dependent Claim
156 words
checking for errors in the received message packet, and transmitting an ackowledgment signal if received with no errors, 2. identifying if the message is a valid message packet, a valid message packet being one which was received without errors, has not expired and is has an message ID which does not match stored message IDs, 3. comparing the destination unit ID to the intemal ID of the recipient mobile unit for the message if it is a valid message packet, 4. storing and utilizing valid message packets which the destination unit ID matches the intemal ID of the recipient mobile unit, 5. determining a time slot assigned to this recipient mobile unit if the message is a valid message packet, and 6. re-broadcasting the message packet to other recipient mobile units in a non-interfering fashion at a time period other than that assigned to this recipient mobile unit if the message is a valid message packet.
Claim 5
Dependent Claim
155 words
The method of transmitting message information of claim 1 further comprising, after the step of re-broadcasting the message packet, the steps of: a) listening for an acknowledgment (ACK) signal from a recipient mobile unit which has received the message packet without error; b) comparing a count of ACK signals received to a ROBUSTNESS value in the message packet; c) deleting the message except for the message ID if the count of ACK signals meets or exceeds the ROBUSTNESS value, and d) determining if the message has expired and erasing the message if it has expired, and e) re-broadcasting the message packet to other recipient mobile units in a non-interfering fashion at a time period other than that assigned to this recipient mobile unit if the message is a valid message packet; and f) repeating steps a-e if the message packet has not expired and the count of ACK signals does not exceed the ROBUSTNESS value.
Claim 6
Dependent Claim
60 words
The method of transmitting information of claim 1 further comprising, after the step of re-broadcasting the message packet, the steps of: a) detecting if a collision has occurred; and b) re-broadcasting valid message packet after a randomized delay period at a time period other than the slot assigned to this recipient mobile unit to reduce the possibility of another collision.
