Patent ID: 8804679

Claim:
A data transfer method which compensates for delays in transmissions caused by faulty reception of data packets using information to negotiate characteristics of the data transfer, the method comprising: transferring identity of a subscriber terminal from the subscriber terminal to an intermediate station associated with a radio system; transferring at least one data packet from a transmitter to the subscriber terminal through the intermediate station; negotiating characteristics of the data transfer during transferring the at least one data packet to compensate for delays in transmission and retransmission, the characteristics comprising at least one of data transfer protocol, bandwidth reservation, and data compression method; saving each data packet in the intermediate station; detecting a faulty reception of a data packet in the subscriber terminal; transmitting, from the subscriber terminal, initiating a request for retransmission of the data packet associated with the faulty reception in response to a message indicating faulty reception; retransmitting, from the intermediate station to the subscriber terminal, a saved data packet in response to the request caused by faulty reception of the data packet using the negotiated data transfer characteristics; and performing signaling of the subscriber terminal to the transmitter by the intermediate station including data transfer according to the negotiated data transfer characteristics, the signaling being an emulation of an information response message ordinarily sent by a receiver to the transmitter, with an emulated information response message sent by the intermediate station in place of the transmitter in response to reception of the at least one data packet of data packet protocol context transmitted by the transmitter and addressed to the subscriber terminal and received by the receiver, the emulation being based on the identity of the subscriber terminal transferred to the intermediate station, wherein the subscriber terminal is coupled to the intermediate station through a delay network comprising an undetermined delay of about at least a second, the transmitter being coupled to the intermediate station through a connection comprising a nearly constant delay that is shorter than that of the delay network, thereby compensating for delays in transmissions caused by faulty reception of data packets using information to negotiate characteristics of the data transfer.
