Abstract: A method and apparatus for load balancing and overload control of packet media gateways under control of a single media gateway controller is provided. More particularly, the invention is directed to a technique for load balancing and overload control by defining an interface between the media gateway (MG) and the media gateway controller (MGC) to handle both load balancing as well as general congestion and resource congestion.
