ABSTRACT:
A method and apparatus for handling an overload condition in a communication network are disclosed. For example, the method calculates a retry-after-timer parameter by at least one core signaling network element for at least one edge signaling network element. The method then sends the retry-after-timer parameter 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 retry-after-timer parameter is used by the at least one edge signaling network element in an overload control that throttles signaling traffic.
