Abstract: Provided are an entity configuration method, device and system, a gNB-CU-User Plane (gNB-CU-UP). The entity configuration method includes: acquiring, through an Xn interface, specified information for configuring each packet data convergence protocol (PDCP) entity for processing a data radio bearer, where the Xn interface is an interface between a gNB-CU-Control Plane (gNB-CU-CP) and a gNB-CU-UP; and configuring the each PDCP entity according to the specified information. The present disclosure solves the problem of how to implement configuration of a gNB-CU-UP protocol entity and achieves centralized traffic convergence.

Abstract: Provided is a data packet transmission method and device. The method includes: generating, by a first network element, first indication information according to a delivery status fed back by a second network element to the first network element, where the first indication information is used for instructing the second network element which has not successfully sent a data packet to a terminal to discard the data packet indicated by the first indication information. The present disclosure may solve the problem in the related art of unsynchronized data transmission in sending of a data packet to a terminal by a plurality of second network elements.
