Abstract: The present invention relates to traffic profiling in real time within a video streaming session. First, multiple data packet flows at a lower layer of the OSI model are observed. A data packet flow pattern is obtained for each observed flow, and each obtained pattern is compared to a pre-defined characteristic streaming pattern. From the observed flows, any data packet flow that has its data packet flow pattern close to the pre-defined characteristic streaming pattern is selected as a video streaming flow. A buffer state of the video streaming flow is identified amongst a filling state, a steady state, and a depletion state, by observing a slope of accumulated data over time. Eventually, multimedia-related information of the selected video streaming flow is provided based on its data packet flow pattern.

Abstract: An apparatus and method are provided for estimating a refined location in dependence on a plurality of measurements of one or more communication channels. The apparatus comprises one or more processors configured to: compress each channel measurement; process the compressed channel measurements using a neural network to form a plurality of intermediate location estimates; and process the intermediate location estimates to form the refined location.

Abstract: A communication entity for transmitting a video data stream at a target transmission bit rate and corresponding method are provided. The communication entity comprises: a first scheduling instance configured to determine a preliminary transmission bit rate for forwarding the video data stream towards the user equipment; and a second scheduling instance configured to determine the target transmission bit rate based on the preliminary transmission bit rate and a set of video bit rates, the set of video bit rates comprising a first video bit rate associated with a first video quality and a second video bit rate associated with a second video quality, the first video bit rate being smaller than the second video bit rate, wherein the second scheduling instance is configured to select the preliminary transmission bit rate as the target transmission bit rate if the preliminary transmission bit rate does not exceed the first video bit rate.
