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.
Claims20
A method for handling an overload condition in a communication network, comprising:
- calculating a call target rate by at least one core signaling network element for at least one edge signaling network element;
- and
- sending said call target rate 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 call target rate 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 call target rate by at least one core signaling network element for at least one edge signaling network element;
- and
- sending said call target rate 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 call target rate is used by said at least one edge signaling network element in an overload control that throttles signaling traffic.
An apparatus for handling an overload condition in a communication network, comprising:
- means for calculating a call target rate by at least one core signaling network element for at least one edge signaling network element;
- and
- means for sending said call target rate 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 call target rate is used by said at least one edge signaling network element in an overload control that throttles signaling traffic.
