Abstract
A data transmission method of a GPRS includes estimating a possibility of an impending stall state of a transmit window, transmitting a stall state alarm signal of the transmit window to a network if it is predicted that the stall state of the transmit window is approaching, and controlling data transmissions according to whether an ACK signal for the stall state alarm signal is received or not from the network. Notification of the possibility of the stall state of the transmit window is provided at least once and preferably twice to the network before stall actually occurs, thereby reducing the number of occurrences of the transmit window's stall state. As a result, waste of network resources due to re-transmission performed in the stall state is minimized.
