The present invention relates to a handover method and apparatus in a wireless communication system supporting an eICIC function. A communication method of a first base station in a heterogeneous network wireless communication system, which includes the first base station and a second base station and supports a cell range expansion (CRE) function, comprises the steps of: monitoring whether the cell range expansion function is deactivated; when the deactivation of the cell range expansion function is detected, generating a handover request message; and transmitting the handover request message to the second base station.
