Abstract: The present invention relates to efficient handover processing for a multi-mode mobile station supporting a licensed wireless system and unlicensed wireless system. A handover processing method using unlicensed mobile access (UMA) includes: checking, upon recognition of necessity of handover, neighbor cell information from a licensed wireless system; determining possibility of handover on the basis of the neighbor cell information; preventing, if handover is not possible, a handover-related operation, and maintaining an existing connection to the licensed wireless system; and performing, if handover is possible, handover to an associated unlicensed wireless system.
