Traffic profiling in real time within a video streaming session is described. 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.

For each base station, transmit power level variables (I values) for each resource block allocated by the base station are initialized. The I values are used in a model to find sub-gradients for each base station. Neighboring base stations exchange the sub-gradients. For each base station, the base station's sub-gradient and the base station's neighbors' sub-gradients are used in the model to update the I values. Neighboring base stations then exchange the updated I values. For each base station, the base station's updated I value and the base station's neighbors' updated I values are used in the model to update the initial sub-gradients. The updated sub-gradients are then exchanged and used for another update of the I values. After a number of iterations, the I values are used to establish a transmit power level per resource block.
