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 a method for transmitting a control signal for determining a keep alive status of a counterpart node in a broadband communication network are provided. When a period for determining a keep alive status of the counterpart node to which a data is connected arrives, whether traffic is received from the counterpart node is determined. If it is determined that the traffic is received from the counterpart node, the keep alive status of the counterpart node is determined using the traffic received from the counterpart node. If it is determined that the traffic is not received from the counterpart node, a request signal for determining the keep alive status of the counterpart node is transmitted to the counterpart node.
