Abstract: In one example method, a first network node transmits a first control message, which indicates a set of candidate mobile edge computing (MEC) hosts, a client device, and network performance boundaries for selection of a MEC host, to a second network node. The first network node receives a second control message, which indicates a subset of the set of candidate MEC hosts and performance of a fastest path from the client device to each candidate MEC host in the subset of candidate MEC hosts, and probabilities of the client device entering a coverage area of the each candidate MEC host, from the second network node. The first network node transmits a third control message indicating a selected MEC host to the second network node. The second network node selects a user plane function (UPF) for traffic steering to the selected MEC host based on the third control message.

Abstract: A video generating device obtains Laplace pyramid levels of 360° video frames; upscales each of the obtained Laplace pyramid levels so as to recover a set of corresponding Gaussian pyramid levels for each 360° video frame; determines a recovered Gaussian pyramid level among the set of recovered Gaussian pyramid levels for each pixel in each 360° video frame based on a bitrate budget for live streaming and a viewport region by performing a pyramid level assignment procedure; composes a 360° video with heterogeneous spatial quality based on summing up the determined recovered Gaussian pyramid levels for each pixel in each 360° video frame. Thereby, reduction of bitrate while providing a high video quality to the user when watching 360° videos is possible. Furthermore, the disclosure also relates to a download proxy comprising such a video generating device, corresponding methods, and a computer program.

Abstract: Transmitting and receiving arrangements and methods in a Digital Subscriber Line (DSL) system having a plurality of modems and vectored transmission capability. A first part of an available frequency band is reserved for vectored DSL transmission and reception using modems operating in the first part of the frequency band. The remaining, second, part of the available frequency band is reserved for both vectored and non-vectored transmission using modems operating in the second part of the frequency band.

Abstract: The invention relates to a method for fault analysis in a multi-layer network. The method includes receiving a first set of performance measurements occurring in response to the fault and representing at least a first and a second layer in a multi-layer communications network. A probable set of network elements affected by the fault are localized. The type of fault is inferred from one or more symptoms in the performance measurements. The root cause of the failure is determined from a combination of information on probable set of network elements and inferred type of fault. The invention also relates to a network management node for carrying out the method. The node includes a root cause analyzer to detect affected network elements and fault type upon network failure, wherein affected network elements are determined in a spatial localization unit and the fault type is determined in a fault type inference unit.
