Abstract
A data forwarding method and device, a master base station and a slave base station are provided. The data forwarding method includes: after receiving a handover request message sent by a second master base station, if it is determined that a slave base station node is newly added, a service data adaptation protocol (SDAP) layer of a part of flows of a preset protocol data unit (PDU) session is configured at a master base station node, and an SDAP layer of the rest part of flows of the preset PDU is configured at the newly added slave base station node, sending a handover request response message carrying first preset information to a second master base station. The first preset information includes: first identity identifications of all flows configured for the first master base station and data forwarding addresses corresponding to the first identity identifications, and second identity identifications of all flows configured for the newly added first slave base station and data forwarding addresses corresponding to the second identity identifications.
