Abstract: Provided in the present application are a report sending method, a terminal, a base station, an apparatus and a storage medium. The method comprises: according to an identifier of a first MRB, which is configured by a target base station for a QoS flow of a target MBS service, determining an identifier of a second MRB, which is configured by a source base station for the QoS flow of the target MBS service; and by means of a packet data convergence protocol (PDCP) entity corresponding to the identifier of the second MRB, sending, to the target base station, a PDCP state report for the QoS flow of the target MBS service. In the embodiments of the present application, by means of using a PDCP entity which has been established for a first MRB of a source base station before switching, the release and establishment processes of a PDCP entity corresponding to a second MRB are prevented from being triggered during the switching to a target base station, thereby guaranteeing lossless transmission based on a PDCP state report, and guaranteeing the reliability of data transmission.

Abstract: Disclosed in the present application are a handover method and apparatus, relating to the field of communications, and being used for reducing the interruption time of data transmission in a distributed unit DU handover process when the central unit control plane/central unit user plane CU-CP/CU-UP in a base station are separated, enhancing the user experience. In the handover method provided in the embodiments of the present application, a notification sent by the CU-CP to the CU-UP not only carries tunnel switching instruction information, but also comprises maintenance instruction information, the maintenance instruction information instructing the CU-UP to continue sending downlink data by means of the original downlink tunnel, such that downlink data can still be received when the user device is not yet connected to a target DU, thereby reducing the interruption time of data transmission during the DU handover process, and enhancing the user experience.
