Abstract
Disclosed is an interworking device for interworking with a first network and supporting signaling between a terminal and a second network. The interworking device sets a first wireless data path with the first network. The interworking device sets a first radio link with the terminal, receives an authentication message through a first radio link, and transmits the authentication message to an authentication server of the second network through the first wireless data path. When the authentication server finishes authentication, the interworking device sets a second wireless data path with the terminal. Accordingly, the interworking device provides an Internet service to the terminal during movement.
