METHOD, SYSTEM AND EVOLVED NODEB APPARATUS FOR IMPLEMENTING INTER-EVOLVED NODEB HANDOVER

摘要

A method, a system and an evolved NodeB(eNB) apparatus for implementing inter-eNB handover are disclosed in the present invention. The method includes the following steps: when a user equipment hands over from a source-side eNB to a target-side eNB, if the target-side eNB knows via the Mobility Management Entity(MME) that the Serving Gateway(S-GW) has changed, the target-side eNB adds the new route relation of the S-GW and then updates the General Packet Radio Service(GPRS) Tunnelling Protocol User Plane(GTP-U) entity. The present invention can effectively solve the problem of the uplink data packet loss due to the time difference existing between the update to the Tunnel Endpoint Identifier(TEID) and the route table by the eNB when inter-eNB handover is performed via X2 and on the condition that the S-GW has changed, thus enhancing the user experience during the handover.
