A handover method of Source eNB and Source eNB thereof

摘要

This invention relates to a handover processing method between a base station in a mobile communication system. Handover processing method in a mobile communication system according to the present invention includes the steps of receiving a message and the radio access bearer message including radio access chopping reoeo (Radio Access Bearer) information for the radio resource reset and the packet forwarding from the target base station If the UL packet forwarding indicator bit representing the phase information and the UL packet forwarding indicator to search for information is set to '1', the source base station comprises the step of forwarding the UL packet and the DL packet. ; According to the present invention, can be in the handover preparation phase handover request by forwarding the packet to UL UL packet forwarding indicator included in the handover response message preferred than the center of the receiving end and, at the packet forwarding UL UL packet in the bitmap information of the bitmap can reduce the size of unnecessary control signals of the inter-base station handover by sending a bitmap with a size optimized in transmitting the information to the variability in, reducing the bitmap processing time in the target base station be in, there is an effect that it is possible to perform more efficient handover.
