Abstract: The present application relates to a timer control method, a data packet processing method, and a device. The timer control method comprises: a receiving device reconstructs a PDCP layer or restores data of the receiving device; if a reordering timer of the PDCP layer is in a running state, the PDCP layer stops running the reordering timer, the reordering timer being used by the PDCP layer to wait to receive a lost data packet. Since the reordering timer is stopped running, and does not time out, the PDCP layer does not update the value of RX_DELIV. Therefore, an effective time window does not change. Therefore, after the PDCP layer is completed reconstructing, if the PDCP layer receives a data packet again, determination can be also made according to the original effective time window, thereby reducing the packet loss rate and minimizing the possibility that the PDCP layer delivers disordering data packets to an upper layer.
