Abstract

A network operation method in an interactive satellite communications system interworking with an external network without modifying a network setting is provided. The network operation method in a base station of the interactive satellite communications system includes the steps of: receiving a data request packet from a user; converting a private internet protocol (IP) address of the user into a public IP address; transmitting the data request packet to an external server; receiving a response packet to the data request packet from the external server and converting the converted public IP address into the private IP address; and transmitting the received response packet to the user by using information on a mapping table.

Claims

1. A method for operating a network in a base station of a satellite communications system, comprising the steps of:

receiving a data request packet from a user;

converting a private internet protocol (IP) address of the user into a public IP address;

transmitting the data request packet to an external server;

receiving a response packet to the data request packet from the external server and converting the converted public IP address into the private IP address; and

transmitting the received response packet to the user by using information on a mapping table.

2. The method as recited in claim 1, wherein the receiving of the data request packet is carried out through a terminal station and the terminal station is allocated with a private IP address of the terminal station, a gateway address and a range of private IP addresses to be allocated to the user from the base station.

3. The method as recited in claim 2, wherein the information on the mapping table includes a media access control address of the terminal station and the range of private IP addresses to be allocated to the user.

4. The method as recited in claim 3, wherein the transmitting of the response packet to the user is carried out by converting the received response packet into a multi-protocol encapsulation (MPE)/moving picture experts group (MPEG)-transport stream (TS) packet by using the information on the mapping table and transmitting the converted MPE/MPEG-TS packet to the user through the terminal station.
