    摘要： This application provides a data packet processing method and device. The method includes: during re-establishment of a packet data convergence protocol PDCP entity or data recovery, if a first timer is running, stopping and resetting, by a receiving device, the first timer, where the first timer is used to detect a loss of a received data packet or is used to detect whether a received data packet is out of order; and setting, by the receiving device, a value of a first variable to a value of a second variable, where the first variable indicates a count value of a next data packet that the receiving device expects to receive, and the second variable indicates a count value of a data packet that is still waiting and is the first data packet that is not delivered to an upper layer. The data packet processing method provided in this application can resolve a problem that a packet loss may occur after PDCP re-establishment or data recovery because a reordering timer is started prematurely, thereby improving data transmission accuracy and data transmission efficiency, and improving user experience.
