Network operation method in interactive satellite communications system

摘要

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.
