SYSTEM AND METHOD FOR OVERLOAD CONTROL IN A NEXT GENERATION NETWORK

SYSTEM AND METHOD FOR OVERLOAD CONTROL IN A NEXT GENERATION NETWORK

A Call Server in a network is able to monitor an offered rate of incoming calls per Access Gateway (AGW). A calculated GlobalLeakRate can be distributed between the AGWs in proportion to the traffic rate they offer. A leak rate calculation method is used to calculate the GlobalLeakRate control param...

description A Call Server in a network is able to monitor an offered rate of incoming calls per Access Gateway (AGW). A calculated GlobalLeakRate can be distributed between the AGWs in proportion to the traffic rate they offer. A leak rate calculation method is used to calculate the GlobalLeakRate control parameter of the ETSI NR restrictor at an overloaded Control Server. The leak rate calculation is based on the POTS call rejection rate. In one particular embodiment of the present invention, the calculation is based on bringing the call reject rate close to a configurable low target reject level. An MGC is able to identify the end of an overload event with a greater degree of confidence and an AGW is able to respond appropriately if the AGW is prematurely instructed to stop the control.
