A method for supporting handover of a moving entity by a serving base station, the method comprising: determining whether the moving entity is a mobile terminal or a moving cell when the moving entity accesses the serving base station; transmitting a handover pre-processing request message to a neighboring base stations when the moving entity is determined to be the moving cell and receiving, from the neighboring base stations, a handover pre-processing response including identifiers for the moving cell after handover and random access preambles; transmitting a measurement configuration message including measurement configuration regarding neighboring base stations, to the moving entity; receiving a handover accept message from a target base station, to which the moving entity will perform handover, among the neighboring base stations; transmitting a radio resource control, RRC, reconfiguration message indicating reconfiguration of RRC connection, to the moving entity; and returning, to other neighboring base stations except the target base station among the neighboring base stations, identifiers and random access preambles received from the other neighboring base stations among the identifiers and the random access preambles received from the neighboring base stations in accordance with the reception of the handover accept message, wherein the handover accept message is received without determining initiation of the handover and the target base station of the moving cell and without receiving a measurement report from the moving cell; wherein when the moving entity is determined to be the mobile terminal, the serving base station determines initiation of the handover and the target base station, after receiving, from the mobile terminal, a measurement report in response to the measurement configuration message. determining whether the moving entity is a mobile terminal or a moving cell when the moving entity accesses the serving base station; transmitting a handover pre-processing request message to a neighboring base stations when the moving entity is determined to be the moving cell and receiving, from the neighboring base stations, a handover pre-processing response including identifiers for the moving cell after handover and random access preambles; transmitting a measurement configuration message including measurement configuration regarding neighboring base stations, to the moving entity; receiving a handover accept message from a target base station, to which the moving entity will perform handover, among the neighboring base stations; transmitting a radio resource control, RRC, reconfiguration message indicating reconfiguration of RRC connection, to the moving entity; and returning, to other neighboring base stations except the target base station among the neighboring base stations, identifiers and random access preambles received from the other neighboring base stations among the identifiers and the random access preambles received from the neighboring base stations in accordance with the reception of the handover accept message, wherein the handover accept message is received without determining initiation of the handover and the target base station of the moving cell and without receiving a measurement report from the moving cell; wherein when the moving entity is determined to be the mobile terminal, the serving base station determines initiation of the handover and the target base station, after receiving, from the mobile terminal, a measurement report in response to the measurement configuration message.
