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.
Claims20
A method for handling an overload condition in a communication network, comprising:
- calculating a retry-after-timer parameter by at least one core signaling network element for at least one edge signaling network element;
- and
- sending said retry-after-timer parameter by said at least one core signaling network element to said at least one edge signaling network element, when a total queueing delay of said at least one core signaling network element exceeds a predefined high threshold in a measurement interval, wherein said retry-after-timer parameter is used by said at least one edge signaling network element in an overload control that throttles signaling traffic.
A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform the steps of a method for handling an overload condition in a communication network, comprising:
- calculating a retry-after-timer parameter by at least one core signaling network element for at least one edge signaling network element;
- and
- sending said retry-after-timer parameter by said at least one core signaling network element to said at least one edge signaling network element, when a total queueing delay of said at least one core signaling network element exceeds a predefined high threshold in a measurement interval, wherein said retry-after-timer parameter is used by said at least one edge signaling network element in an overload control that throttles signaling traffic.
