METHOD AND APPARATUS FOR PRIORITIZING VOICE OVER INTERNET PROTOCOL SIGNALING MESSAGES

摘要

A method and apparatus for enabling prioritization of signaling messages in a communication network are disclosed. For example, the method receives at least one signaling message, and classifies each of the at least one signaling message. The method schedules each of the at least one signaling message for processing, and discards selectively one or more signaling messages that have been scheduled under an overload condition.

主权项

1. A method for discarding a signaling message in a communication network, the method comprising:
receiving, by a processor, the signaling message; classifying, by the processor, the signaling message; scheduling, by the processor, the signaling message for processing; and discarding, by the processor, selectively the signaling message that has been scheduled under an overload condition, wherein the discarding comprises:
discarding the signaling message that has been scheduled from a tail of a provisional message queue when the provisional message queue is not empty, when a high priority message or a non-provisional signaling message is newly received and when the signaling message is a provisional signaling message;discarding the signaling message that has been scheduled from a non-provisional message queue when the provisional message queue is empty and the non-provisional message queue is not empty, when a high priority message or a non-provisional signaling message is newly received and when the signaling message is a non-provisional signaling message;discarding a newly received signaling message under the overload condition when the newly received signaling message is a provisional signaling message; anddiscarding the newly received signaling message under the overload condition when both of the provisional message queue and the non-provisional message queue are empty.
