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.

Methods and apparatus for detecting fraudulent traffic associated with a user of a telecommunications system. A system comprises a monitoring network node comprising a traffic monitor configured to monitor traffic transmitted to or from a user in the telecommunications system, a fraud detector configured to apply to the monitored traffic a fraud profile associated with the user to determine whether the monitored traffic comprises fraudulent traffic, a transmitter configured to transmit data to a receiver of a profiling network node notifying whether the monitored traffic comprises fraudulent traffic. The profiling network node further comprises a fraud profiler configured to determine an updated fraud profile associated with the user based at least on the received data and a transmitter configured to transmit data identifying the updated fraud profile to one or both of a receiver of a subscription profile repository and a receiver of the monitoring network node.
