Patent ID: 8570942

Claim:
A wireless LAN terminal comprising: a storage unit that stores profile information including information on a channel of a predetermined access point and an SSID (service set identifier); a unit that sets a channel to be scanned on the basis of a scanning period and said profile information; a passive scanning unit that performs a passive scanning operation at the set channel and checks whether there is a beacon signal transmitted from said access point without sensing the SSID of the transmitted beacon signal; and an active scanning unit that performs an active scanning operation at said set channel by transmitting a probe request signal including said SSID of said predetermined access point, and receiving a probe response signal from the access point which has an SSID identical to the transmitted SSID, so as to detect said access point, wherein, before said active scanning unit performs said active scanning operation at said set channel, said passive scanning unit performs said passive scanning operation at said set channel for each said scanning period, and said active scanning unit performs said active scanning operation at said set channel after said passive scanning unit confirms that there is said beacon signal without sensing said SSID of said beacon signal so as to search for said access point.
