Abstract:
Provided is a method for performing handover by a STAtion (STA) in a radio Local Access Network (LAN) communication system. The method includes sending a Network Controlled HandOver Setup Request Information Element (Ncho Setup Req IE) message indicating that the STA is to perform a scan operation using a controlled scan scheme, to a serving Access Point (AP); receiving a Network Controlled HandOver Setup Response Information Element (Ncho Setup Rsp IE) message including a scan parameter related to a controlled scan operation of the STA, from the serving AP; and broadcasting a probe request message to the serving AP and neighbor APs over channels according to the scan parameter included in the Ncho Setup Rsp IE message.
