Abstract
The present invention relates to an interworking device for interworking with a first network and exchanging data between a second network and a terminal device. The interworking device establishes a first wireless data path with the first network, and receives a first network address from an address allocation server of the first network through the first wireless data path. In addition, the interworking device establishes a second wireless data path with the terminal device, receives a second network address from an address allocation server of the second network through the second wireless data path, and transmits the second network address to the terminal device. Subsequently, the interworking device establishes a tunnel that passes through the first network and is accessed to the second network, and exchanges data with the second network.
