PURPOSE: A method for supplying a wireless Internet service within a mobile body by using a multi-communication network is provided to transmit an upload Internet signal by using a mobile communication network, and to receive a download Internet signal by using a satellite communication network, thereby accessing the Internet at low price while receiving high-speed data. CONSTITUTION: When an Internet request signal is generated, a network server attempts connecting with the Internet through a mobile communication network by calling a cellular phone or a wireless modem(S500,S502). The network server is connected with a mobile communication authentication server, and then is connected with a wireless LAN authentication server(S504,S508). If authentication processes are successful, the Internet request signal is transmitted to a web server(S512). The wireless LAN authentication server transmits a response signal of the web server to a satellite earth station through a satellite delivery device. The satellite earth station delivers the response signal to a satellite(S514). The satellite delivers a satellite signal to the earth, and a satellite Internet receiver extracts the response signal to demodulate into an Internet signal, and transmits the Internet signal to the network server(S516-S520). The network server broadcasts the Internet response signal, and a notebook computer receives the Internet response signal(S522). |
