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.
