Abstract: A cell handover method and a device are provided, so that a target eNB uses a current serving small node as a user plane serving node after a UE is handed over. The UE and uses the target eNB as a control plane serving node after the handover. The method includes 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. According to the application, a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great is avoided, because the current serving small node forwards a large amount of data to the target eNB.
