Gating control in a telecommunication system

摘要

A method and system for updating or handling the update of a media path between a first user terminal and a second user terminal in a telecommunications network is provided. According to an embodiment of the present invention, the media path includes one or more gateway nodes. Each gateway node includes a gating function for gating media packets. Each gating function has an associated controlling function for controlling the gating function. Responsive to a message indicating at an update of the gating at the gating function is required, the gating function arranges for a new gating to be opened while keeping the old gating open. The gating function determines when the media has been switched to the new path. Responsive to the determination, the gating function arranges for the old gating to be closed.
