PURPOSE: A reserve advertising lottery system using a wireless Internet terminal is provided to reduce the terminal usage expenses and increase the utilization of wireless Internet by offering advertising lottery winning opportunities to subscribers. CONSTITUTION: The reserve advertising lottery system(150) is comprised of an AD server(130), a database(135) and a lottery program(140). If advertisement service request signals are received from mobile terminals(110(1),110(M)) through wireless Internet gateway servers(120(1),120(M)), the reserve advertising lottery system(150) sends information stored in the database(135) to the mobile terminals(110(1),110(M)). In this case, the AD server(130), the database(135) and the lottery program(140) are connected with mobile systems(115(1),115(M)) through the medium of the wireless Internet gateway servers(120(1),120(M)). The database(135) contains a goods D/B, a member D/B and a lottery number grant authentication D/B. In case that a subscriber executes goods advertisement inquiries using his mobile terminal, winning prize money is automatically accumulated by the lottery program(140). The accumulated money is distributed through a lottery system(145) in proportion to the number of inquiries.
