Abstract
A network device stores overload handling criteria for a real-time credit management system of a wireless core network. The network device monitors for overload conditions based on the overload handling criteria and determines, based on the monitoring, that a potential overload condition exists. The network device receives a first credit control request for a user device, determines a standard resource quota that is responsive to the first credit control request, and allocates an increased resource quota, over the standard resource quota, for the first credit control request. The increased resource quota is based on the potential overload condition and the overload handling criteria. The increased resource quota may prevent the system from reaching a complete overload condition, may reduce overall message traffic, and may provide time for manual or autonomous recovery from the circumstance that caused the potential overload condition.
