A gateway device that cooperates with a regional network, a terminal device, and a cross-region transferring server. The gateway device includes a first I/O module, an inquiring signal-generating module, a second I/O module, and an analysis module. The first I/O module receives the destination of an output signal from the terminal device. The inquiring signal generating module generates a region distinguishing information-inquiring signal according to the destination of the output signal. The second I/O module outputs the region distinguishing information-inquiring signal to the destination of the output signal via the regional network, and then receives region distinguishing information from the destination of the output signal. The analysis module analyses the region distinguishing information to determine whether or not the destination of the output signal is located in the regional network. In this case, when the destination of the output signal isn't located in the regional network, the second I/O module outputs the output signal to the cross-region transferring server via the regional network, and then the cross-region transferring server transfers the output signal to the destination of the output signal. The invention also discloses a cross-region transferring system, which includes the gateway device, the regional network and a cross-region transferring device.
