Abstract
A method and network entity for downloading detected video packets. A minimum bit rate MinBR equals ViBR+M, where M≧0 is a configurable bit rate margin from an estimated video bit rate ViBR. A specific bit rate SBR is greater than MinBR. The method uses MinBR and SBR as a minimum bit rate limit and a maximum bit rate limit respectively between which the bit rate for delivering video in case of congestion is defined. The method can further compare the predefined specific bit rate with a real throughput of the user requesting video download with a QoS profile, and if there is congestion and if the throughput is larger than or equal to SBR, the priority value of a QoS profile to be used for downloading video in case of congestion.
