摘要： The invention relates to a client device (100), a network control node (300) and a UPF (510) for interworking in a multi-connectivity scenario in a mobile communication system (500). Since an application (110) knows how to achieve desired QoS/QoE in the mobile communication system (500), the present invention exposes the performance information of available network paths and information about QoS fulfillment to the application (110) to dynamically adjust QoS requirements and allocate available resources to its traffic data streams. By exposing network performance information of available paths and changes in QoS fulfillment to application (110) developers in API and letting the application (110) define how to allocate resources for its traffic according to application specific criteria the use of mobile core network and QoS framework for mobile services data transfer can be increased and monetized. Furthermore, the invention also relates to corresponding methods and a computer program.

摘要： The invention relates to a method for fault analysis in a multi-layer network. The method includes receiving (210) 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 (220). The type of fault is inferred (230) from one or more symptoms in the performance measurements. The root cause of the failure is determined (240) from a combination of the information on probable set of network elements and inferred type of fault. The invention also relates to an arrangement in a network management node for carrying out the inventive method. The arrangement includes a root cause analyzer (320) to detect affected network elements and fault type upon network failure, wherein affected network elements are determined in a spatial localization unit (320) and the fault type is determined in a fault type inference unit (350).

摘要： The invention enables a first and a second network node to jointly select an optimal MEC host and UPF in a wireless communication system for low latency performance. The first network node (100) transmits a first control message (510) to a second network node (300), wherein the first control message (510) indicates a set of candidate MEC hosts, a client device (600), and network performance boundaries for selection of a MEC host. The first network node (100) further receives a second control message (520) from the second network node (300), wherein the second control message (520) indicates a subset of the set of candidate MEC hosts and performance of the fastest path from the client device (600) to each candidate MEC host in the subset of candidate MEC hosts, and probabilities of the client device (600) entering a coverage area of each candidate MEC host in the subset of candidate MEC hosts, and transmits a third control message (530) to the second network node (300), wherein the third control message (530) indicates a selected MEC host. The second network node (300) selects (412) a user plane function, UPF, for traffic steering to the selected MEC host based on the third control message (530). Furthermore, the invention also relates to corresponding methods and computer program.

摘要： A video generating device obtains Laplace pyramid levels of 360° video frames; upscales each obtained Laplace pyramid level 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 in dependence 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 invention also relates to a download proxy comprising such a video generating device, corresponding methods, and a computer program.
