Provided are a method and a device for performing a handover in a wireless LAN system operating in a white space band. A method includes: allowing a specific station (STA) to access a service region of a second access point (AP), the specific STA associated with a first AP and storing a first enablement STA identification information (“IDINFO”), the first enablement STA IDINFO being an IDINFO of an enablement STA managing STA enablement from the first AP; receiving a message, from the second AP, including a second enablement STA IDINFO (an IDINFO of an enablement STA managing STA enablement provided by the second AP); comparing the first and second enablement STA IDINFO; if the first and second enablement STA IDINFO are different, performing a procedure for changing an enablement STA and a handover to the second AP, to a second enablement STA, which corresponds to the second enablement STA IDINFO.
