<p><P>PROBLEM TO BE SOLVED: To provide a data transmission method for a GPRS with which waste of shared resources caused by a retransmission of an RLC data block is minimized by predicting and reporting a stall state before a transmit window of terminal equipment is stalled. <P>SOLUTION: Data of the GPRS are transmitted by successively performing: a step for predicting an approach of the transmit window to the stall state; a step for transmitting a stall state alarm signal of the transmit window to a network when it is predicted that the transmit window approaches the stall state; and a step for controlling the transmission of data according to whether an ACK signal for the stall state alarm signal is received or not from the network. <P>COPYRIGHT: (C)2004,JPO</p> |
