The present invention provides a method which enables a hand held electronic device to establish a tunnel between two network terminal devices of remote private network through the internet wherein the private network has at least a computer and at least two network terminal devices connecting to the Internet, and said computer is installed with a Fat UA while said hand-held electronic device is installed with a Thin User Agent enabling said hand-held electronic device to send a control command to said computer through the Internet. After said control command is received, said Fat UA encapsulates said control command in two SIP packets for connection request and connection response and send them to said two network terminal devices respectively. And after said SIP packets are received, said network terminal devices will send the SIP packets with each other so as to automatically establish a tunnel and proceed mutual data access therebetween according to said control command encapsulated in said SIP packets. |
