Abstract:
1. In a radio network using TCP as the transport protocol for acknowledging message packets successfully received at a destination station and retransmitting message packets from the source station which are not acknowledged within a predetermined period of time, a method of reducing the unnecessary retransmission of message packets comprising the steps of: a) receiving a TCP retransmission packet at a source radio from a source station for retransmission to a destination station and maintaining the packet in a message queue until retransmission; b) receiving a TCP acknowledgment packet at the source radio from a destination station; c) comparing the received acknowledgment packet from the destination station with the retransmission packet in the message queue at the source radio; and d) discarding the retransmission packet from the message queue if the retransmission packet corresponds to the acknowledgment packet.
