PACKET FORWARDING METHOD IN THE CASE OF THE HANDOVER BETWEEN BASE STATIONS

摘要

A packet forwarding method during handover between base stations is provided to supply a data format in which a final time of a packet transmitted from a source base station is grasped during handover between base stations. A source base station transmits user data for handover to a target base station(S105). When a packet to be forwarded to the target base station from the source base station does not exist, control data indicating a final time of the forwarding packet is transmitted to the target base station(S110). The target base station recognizes that there are no packet to be forwarded from the control data(S120). The target base station immediately transmits a downlink packet received from a serving gateway to a terminal without a standby time(S130).
