Method and apparatus for performing handover in wireless communication system

A method of performing pre-processing for handover of a moving cell by a neighboring base station adjacent to a serving base station, the method comprising:

• receiving a handover pre-processing request message including information on a handover history of the moving cell, from the serving base station;
• and
• transmitting a pre-processing response message including at least one of a random access preamble allocated from the neighboring base station, radio resource control (RRC) configuration of the neighboring base station and system information of the neighboring base station, to the serving base station,
• wherein the pre-processing response message transmitted from the neighboring base station is forwarded to the moving cell before handover of the moving cell is initiated.

A serving base station for performing pre-processing for handover of a moving cell, the serving base station comprising:

• a backhaul interface for transmitting a handover pre-processing request message including information on a handover history of the moving cell, to at least one neighboring base station adjacent to the serving base station and receiving a pre-processing response message including at least one of a random access preamble allocated from the neighboring base station, radio resource control (RRC) configuration of the neighboring base station and system information of the neighboring base station, from the neighboring base station;
• a radio interface for transmitting the pre-processing response message to the moving cell before handover of the moving cell is initiated;
• and
• a processor for controlling the backhaul interface and the radio interface.

A neighboring base station for performing pre-processing for handover of a moving cell, the neighboring base station comprising:

• a backhaul interface for receiving a handover pre-processing request message including information on a handover history of the moving cell, from the serving base station and transmitting a pre-processing response message including at least one of a random access preamble allocated from the neighboring base station, radio resource control (RRC) configuration of the neighboring base station and system information of the neighboring base station, to the serving base station;
• and
• a processor for controlling the backhaul interface,
• wherein the pre-processing response message transmitted from the neighboring base station is forwarded to the moving cell before handover of the moving cell is initiated.
