- An method for performing a TVBD (TV Band Device) group handover based on TV white space by an AP (Access Point), the method comprising: transmitting multiple location information corresponding to a path along which a mobile vehicle travels to an available channel information providing server; receiving multiple geo-location information from the available channel information providing server as a reply to the transmitted multiple location information; extracting operating channel set information so as to minimize a channel switching caused by the travel of the mobile vehicle, based on the multiple geo-location information; and transmitting the extracted operating channel set information to a TVBD group.
