Abstract: Systems and methods for retransmitting a missing data packet. When at least two reports of the missing data packet are received, then the packet is retransmitted. When a subsequent request for the same data packet is received, then the time difference between the subsequent request and the retransmission is obtained and compared to a predefined retransmission timeout. If the time difference is greater, the packet is again retransmitted.

Abstract: This disclosure describes a system and method for optimizing the transport of payload data on a wireless telecommunications network. For downstream data flow to a mobile communication device client, an application proxy residing on a transmitting server terminates TCP data flows, extracts payload data and encapsulates the data into a UDP packet. A far host server residing on a receiving client device receives the UDP packet, extracts the payload and presents it to an application program on the client device as a TCP packet. For upstream data flow to a server, software running on the mobile communication device acts as the application proxy, extracting payload data from a TCP data flow and encapsulating the extracted data into a UDP packet. The server receiving the UDP packet will extract the payload and present it as a TCP packet.

Abstract: A system and method for managing a session is provided wherein a sending computer, after a period of time in which a number of enumerated packets have been sent to a receiving computer, sends a report request to the receiving computer, which then sends to the sending computer a report containing an acknowledgement of the last packet received from said the sending computer, a list of any enumerated packets not received within the time period, and a rate of receipt of packets from the sending computer. If the sender receives a predetermined number of reports identifying the same packet as the last packet received, the session is terminated.
