Abstract: Disclosed is a method for a 1st moving cell base station to control a handover in a wireless communication system supportive of a moving cell. The present invention includes performing measurement on signals of at least one or more neighbor base stations and determining whether to make a handover based on a result of the measurement. Moreover, the 1st moving cell base station controls the handover not to be made into a 2nd moving cell among the at least one or more neighbor base stations using information on a moving cell dedicated cell ID.
