<p>A method for redirecting network communication port and a network communication system thereof are disclosed. When a receiving end determines that a communication port needs to be redirected, the receiving end sends a redirected address to a transmitting end via a communication port. The redirected address includes redirected address information of a transport layer. The redirected address may also include address information of a network layer of a receiving end which can be reached via a communication port corresponding to the redirected address information of the transport layer. The address information of the network layer of the receiving end includes the address of a network layer of the original receiving end, the address of a network layer of the new receiving end capable of managing the transmitting end, or the address of the network layer of the receiving end supporting the new protocol. According to the present invention, when the gatekeeper is not able to receive, via a well-known port, some of signaling sent from a node, the gatekeeper can inform the transmitting end to switch the port automatically, allowing thereby the node to continue the previous service. The present invention further allows the node to perform protocol switching automatically.</p> |
