<p>The present invention is a transport layer protocol for data packet delivery in a wireless environment. The method of the present invention incorporates a transport data protocol structure to implement a modified go-back-n automatic repeat request for data packet delivery. The invention further employs a distinct pair of sequence numbers and request numbers for client and server originated data packet transmissions. Several packets can be transmitted by the sender without the need for each packet to be individually acknowledged by the receiver. After n successive packets have been transmitted, the sender polls the receiver for an acknowledgment. The acknowledgment (350) sent by the receiving party contains the request number equal to the sequence number of the packet that the receiver requests to be sent next (325). This number represents the last packet which was received in order plus one (325). Lastly, the present invention provides a method for the client and server to imply that an acknowledgment (350) has been sent to it even though the acknowledgement was lost in transmission.</p> |
