Abstract: This disclosure relates to the mobile communications field, and in particular, to a buffer processing technology in a wireless communications system. In a buffer processing method, user equipment UE triggers a direct link buffer status report, where the direct link buffer status report is at least used to report an amount of buffered data generated by the UE for a first service, and the first service is currently transmitted in a device-to-device (D2D) direct communication mode; and when the UE determines to transmit the first service in a base station relay mode, the UE stops reporting the amount of the buffered data generated by the UE for the first service to a base station. In this way, the UE stops reporting the amount of the buffered data of the first service to the base station when the UE switches from direct link transmission to base station relay transmission.

Abstract: Embodiments of the present invention provide a cell handover method and a device. so that the target eNB uses a current serving small node as a user plane serving node after UE is handed over and uses the target eNB as a control plane serving node after the UE is handed over; receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. This avoids a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great because the current serving small node forwards a large amount of data to the target eNB.
