<p>Provided is a smart antenna control method using a handover which can remotely adjust service coverage according to the movement of a train by controlling vertical and horizontal directions of an antenna for a base station and a relay station. According to an embodiment of the present invention, the smart antenna controlling method using a handover comprises the following steps of: setting an RRC connection between a terminal operating a railway and eNB1 disposed around the railway; performing, by the terminal, an intra-handover while moving between cells formed in eNB1 after setting the RRC connection; and performing, by the terminal, a handover through an X2 interface while the terminal is disposed in an identical MME group and is moving between cells formed in eNB2 disposed in a different location from that of eNB1.</p> |
