Abstract: System and method for controlling an image collecting device to carry out a target location are provided, which includes: an acoustic sound source locating unit, configured to carry out target location based on a received acoustical signal and transmit the located position to an application layer strategy unit; a voice recognition unit, configured to carry out a recognition and matching process with a stored acoustical signal based on the received acoustical signal, and transmit the recognition result to the application layer strategy unit; and the application layer strategy unit, configured to decide an expected PTZ position of the image collecting device based on the position and the recognition result. The system controls the image collecting device to automatically carry out a target location based on the results of the acoustic sound source location and voice recognition, which thus improves an operating maintainability of the image collecting device.

Abstract: 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. 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.
