    • A handover performing method for reducing down time by efficiently using operation time of hard handover is provided to reduce latency by efficiently using the operation time of the hard handover. A handover request message is transmitted to a base station(S510). The handover response message including uplink grant time is received from the base station(S520). Until the uplink grant time comes, data communications with the base station is maintained(S530). If the uplink grant time comes, the uplink grant is received from the base station. The hand-over direction message is transmitted to the base station(S560).
