Abstract

A method and apparatus for handling an overload condition in a communication network are disclosed. For example, the method calculates a call target rate by at least one core signaling network element for at least one edge signaling network element. The method then sends the call target rate by the at least one core signaling network element to the at least one edge signaling network element, when a total queueing delay of the at least one core signaling network element exceeds a predefined high threshold in a measurement interval, wherein the call target rate is used by the at least one edge signaling network element in an overload control that throttles signaling traffic.
