Method and network node for monitoring a quality of media transfer in a session initiation protocol based voice over internet protocol communications network

摘要

Method and network node for monitoring a quality of media transfer in a SIP based VoIP communications network comprising a first and second network node. The method includes the step of collecting, by the first network node, information representative of the quality of media transfer on the user plane, such as information included in one or more RTCP messages related to that media transfer, and including, by the first network node, in a SIP message said information representative of the quality of media transfer on the user plane. The method further includes transmitting the SIP message from the first network node to the second network node, and storing in a repository associated with the second network node the information representative of the quality of media transfer on the user plane.

1. A method for monitoring a quality of media transfer in a Session Initiation Protocol (SIP) based Voice over Internet Protocol (VoIP) communications network comprising first and second network nodes, the method comprising:
the first network node updating the second network node with quality information representative of a quality of a media transfer on a user plane of a first early dialog associated with establishment of a SIP session supporting a particular VoIP call, the updating comprising:
collecting the quality information at the first network node;detecting a response to a second early dialog associated with the establishment of the SIP session supporting the VoIP call; andin response to the detecting, transmitting a first SIP message comprising the quality information to the second network node; wherein the first early dialog is distinct from the second early dialog.
