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 distribu ted between the AGWs in proportion to the traffic rate they offer. A leak ra te calculation method is used to calculate the GlobalLeakRate control par...

Zusammenfassung:	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 distribu ted between the AGWs in proportion to the traffic rate they offer. A leak ra te calculation method is used to calculate the GlobalLeakRate control parame ter 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 emb odiment of the present invention, the calculation is based on bringing the c all reject rate close to a configurable low target reject level. An MGC is a ble 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 inst ructed to stop the control.
