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.

Abstract: Example mapping methods and apparatus are described. One example method includes determining a message type of an uplink signaling message by an integrated access and backhaul node. The integrated access and backhaul node maps the uplink signaling message to a corresponding backhaul radio link control (BH RLC) based on an uplink mapping relationship from an integrated access and backhaul donor centralized unit and the message type. The uplink signaling message is sent to a parent node of the integrated access and backhaul node.
