The present invention provides an X2 handover method and device, the method comprises: after sending a Handover Request Acknowledge message, a target eNB sets, for handed-over UE, a flag for indicating whether or not a Sequence Number Status Transfer message is received and sets the flag to be 'not received'; and after receiving an RRC Connection Reconfiguration Complete message, the target eNB directly sends a Path Switch Request message to a core network without determining whether or not the Sequence Number Status Transfer message is received. With the technical scheme provided in the present invention, the problem in the current X2 handover is solved that handover delay is increased as an RRC Connection Reconfiguration completion message is received by a target side prior to a Sequence Number Status Transfer message, thus simplifying the processing of a target eNB and increasing handover speed. |
