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.

Apparatus and method for performing handover in radio local access network communication system

An apparatus and method for providing/receiving a voice service in a Wireless Local Access Network (WLAN) system. In the voice service provision method, an Access Point (AP) generates a multiplexing voice data packet by performing a multiplexing operation on at least two voice data packets among received voice data packets, and performs a multicast operation of multicasting the multiplexing voice data packet to Mobile Stations (MSs) which should receive the at least two voice data packets.
