摘要
PCC control of HTTP adaptive bit rate video streaming protocols. This PCC control is enforced in a network node that is in communication interaction with a user terminal, UE, and a media server, and is configured to: perform a deep packet inspection, DPI, on IP packets sent from the media server to the UE to detect an association between a plurality of identifiers and corresponding characteristics of respective different media streams representing the same media information; perform a DPI on IP packets sent from the UE to the media server to detect a media stream identifier selected by the UE from said association, the IP packets corresponding to a request to obtain one of the different media streams of the association; and modify the request by replacing the detected media stream identifier selected by the UE with any other of the media stream identifiers of the association.
