Abstract
In order to reduce a disruption of communication which occurs upon performing an active scan, an access point (_) includes an interface on DS side (_) which communicates with different access points (_and_) through distribution system (DS) media (), and an interface on terminal side (_) which generates, when receiving from a terminal () not being in communication with the access point through a radio channel (CH) a probe request frame (FR) which is the one for scanning an access point capable of communicating with the terminal and which includes an address (A_) for the DS media () to identify the different access point (_) being in communication with the terminal (), a response frame (FR) addressed to the address (A_) and responding to the probe request frame (FR), and makes the interface on DS side (_) transmit the response frame (FR) to the DS media ().
