Abstract:
1. A method of controlling call admission within a system including a plurality of media gateways interconnected by a packet switched backbone, the method comprising the steps of: monitoring a level of congestion suffered by incoming packets for a first media gateway, wherein said incoming packets are transmitted from a group of said plurality of media gateways over said backbone, wherein said first media gateway acts as a terminating media gateway for said group of media gateways, and wherein said group of media gateways is organized as a subnet and is identifiable by applying a specific subnet mask to an address in incoming packets from the group of media gateways; receiving a request for said first media gateway to terminate a new bearer connection extending over said backbone from a second media gateway within said group of media gateways to said first media gateway; making a decision on the admissibility of the request based upon a previously monitored level of congestion suffered by incoming packets transmitted from said group of media gateways to said first media gateway; and rejecting or accepting said request based on said decision.
