<p>PURPOSE: A method for controlling a data call traffic frame of a mobile communication system is provided to control a frame transceiving process by giving a sequence number to a traffic frame, thereby retransmitting a lost frame from an SDU(Selection and Distribution Unit) without passing through a wireless section. CONSTITUTION: An SDU(210) transmits a traffic frame including a sequence number to a PCF(Packet Control Function)(230), and stores the traffic frame in a temporary buffer. The PCF(230) receives the traffic frame, checks a sequence order, and confirms whether the traffic frame has the sequence number for receiving. If not, the PCF(230) transmits a retransmission request frame to the SDU(210). The SDU(210) confirms whether a frame has a sequence number for retransmission by retrieving the stored traffic frame, and retransmits the corresponding traffic frame to the PCF(230).</p> |
