Abstract: PURPOSE: A satellite Internet service method is provided to enable a user to access a specific ISP(Internet Service Provider) using a different ISP network and to use satellite Internet services, even though a specific contract has not been made between ISPs. CONSTITUTION: After accessing an ISP that provides generic Internet services and a tollgate server that provides satellite Internet services through a terminal, a user is allocated an IPa address and an IPb address respectively(S10). The user sends a data request command of packet 1 for specific information to a specific web server through a web browser(S11). A tollgate part in the terminal generates packet 2 equivalent to the data request command as a new IP packet, and transmits it to the ISP. The ISP transmits packet 2 to the toll gate server through the Internet according to a destination IP address(IPtol)(S12). If packet 2 is delivered to the tollgate server, the tollgate server removes the header of packet 2 and creates packet 3 identical to packet 1. Then the tollgate server confirms an IPb, source IP address of packet 3, compares it with user information stored in a user DB, and confirms a user for the IPb(S13). Then the tollgate server, confirming an IPweb, destination IP address of packet 3, and checks information stored in a cache to judge whether access to the web server has performed before(S14). In case that it is judged that no one has accessed the web server before, the tollgate server transmits packet 3 to the web server through the Internet according to the IPweb(S15). In response to packet 3, the web server creates packet 4 and transmits it through the Internet. Packet 4 is transmitted to the tollgate server according to the IPb. The tollgate server confirms information data for an Internet site from packet 4(S16), and transmits the information data of packet 4 to the user terminal through a satellite(S17).
