Abstract:
A method for forwarding data during cell handover includes: forwarding, by a source base station, user plane data of Packet Data Convergence Protocol, PDCP, data units that have not been transmitted to a User Equipment, UE, to a target base station in a PDCP layer during cell handover. In addition, embodiments of the present invention further provide a system and devices for forwarding data during cell handover. In the method, a system and base stations are provided by the present invention, the data that have not been transmitted are forwarded in a layered manner respectively in at least one of the PDCP layer and RLC layer. Therefore, data transmission during cell handover is implemented and data loss due to the handover is avoided.
