INTER-NETWORK CONNECTION RELAY DEVICE FOR DIFFERENT KIND OF NETWORKS

摘要

A device for relaying heterogeneous network access is provided to relay data through protocol conversion between a user terminal and a corresponding network. A WiBro connector(14) receives an authorized IP(Internet Protocol) address by connection to WiBro(Wireless Broadband). An access relay controller(15) converts the authorized IP address received from the WiBro connector into a private IP address. The access relay controller relays data through protocol conversion between a wireless Internet terminal connector(11) and the WiBro connector. The wireless Internet terminal connector permits access of a wireless Internet terminal by receiving a heterogeneous network access request using a password from the wireless Internet terminal. The wireless Internet terminal connector transfers the private IP address received from the access relay controller to the wireless Internet terminal.
