Systems and methods to select peered border elements for an IP multimedia session based on quality-of-service

摘要

Systems and methods to select peered border elements for a communication session based on Quality-of-Service (QoS) are disclosed. An example method includes selecting a peered border element to handle a communication session based on a list of peered border elements (PBEs) and a composite QoS parameter of the communication session, the list of PBEs being prioritized based on respective statuses of PBEs in the list, the first composite QoS parameter being based on weighted QoS parameters of the communication session including a grade of service (GoS) parameter of the communication session and a preferred mode of communication for a VoIP device of a called party in the communication session, the GoS parameter including an attempted performance range and an expected performance range of the communication session; and controlling a second server to generate a QoS authorization token to reserve network resources associated with the selected PBE.

主权项

1. A method to assign peered border elements to a communication session, comprising:
selecting, by executing a first instruction with a processor, a peered border element to handle a communication session based on a list of peered border elements and a first composite quality-of-service parameter of the communication session, the list of peered border elements being prioritized based on respective statuses of the peered border elements in the list, the first composite quality-of-service parameter being based on weighted quality-of-service parameters of the communication session including a grade of service parameter of the communication session and a preferred mode of communication for a voice over Internet protocol device of a called party in the communication session, the grade of service parameter including an attempted performance range and an expected performance range of the communication session, the grade of service parameter being based on a level of service for the communication session, and the preferred mode of communication indicating one of multiple devices at which the called party prefers to be reached; and controlling, by executing a second instruction with the processor, a second server to generate a quality-of-service authorization token to reserve network resources associated with the selected peered border element.
