A method of performing a handover between heterogeneous networks and user equipment apparatus for the same are disclosed. The user equipment apparatus includes a first type communication module configured to transceive a signal with a first type base station (BS) using a first wireless communication scheme, a second type communication module configured to transceive a signal with a second type BS using a second wireless communication scheme, and a processor configured to control the handover to be performed on a second type BS operating in an idle state with the second type communication module when a signal is received from a first type BS operating in an active state with the first type communication module, wherein the signal request that the UE performs the handover to the second type BS operating in an idle state with the second type communication module from the first type BS.
