  • Patent number: 10798736
    Abstract: A method performed by a first network node (110), for managing channel access for a Wireless Device (WD) (120). The WD (120) supports one or more Radio Access Technologies (RATs). The first network node (110) receives a radio channel access request from the WD (120), which radio channel access request comprises information regarding a number of requirements on the channel access. The first network node (110) determines a channel access schedule based on the received information and channel statuses for the channels and RATs available within a geographical served by the first network node (110). The channel access schedule comprises information about the radio channel assigned to the WD (120). The first network node (110) further sends the channel access schedule to the WD (120).

  • Publication number: 20200202756
    Abstract: A content distribution node that distributes content to display devices which are arranged in a spaced apart sequence along a pathway of vehicles for display to passengers. The content distribution node receives from a mobile gateway node of a vehicle, through a Light Fidelity signal receiver circuit, a profile message containing profile information related to the vehicle. The content distribution node selects, from among content files available in a content repository, a set of video frames for distribution to the display devices based on the profile information. The content distribution node distributes different video frames among the set of video frames to different ones of the display devices with timing of the distribution that allows the video frames among the set to be displayed on respective ones of the display devices in the sequence before arrival of the vehicle within a field-of-view of at least one of the display devices.

  • Publication number: 20200187086
    Abstract: Methods and apparatus for routing data packets in a communications network, such as a packet-switched network (e.g. an IP network). Instead of, or in addition to, conventional routing techniques such as longest prefix matching, the disclosure provides a method by which a network node can determine whether to defer transmission of a particular data packet based on geographical location and velocity data. Particularly for data that can tolerate high latency, this will serve to reduce consumption of network resources without adversely impacting user experience.

  • Patent number: 10680940
    Abstract: Optimized complex event processing in a software-defined network is provided. A computing device receives a rule that identifies a source device and an event notification condition. A network inventory structure that identifies a plurality of nodes in the network and corresponding processing capabilities is accessed. A particular datapath node of the plurality of nodes is identified. A packet flow window criterion and a packet operation are determined based on the event notification condition. A particular virtual network function (VNF) of a plurality of VNFs is identified based on the rule. A controller node datapath configuration command that comprises a source device identifier that identifies the source device, the packet flow window criterion, the packet operation, and a VNF identifier that identifies the particular VNF is generated. The controller node datapath configuration command is sent to a controller node of the plurality of nodes.

  • Publication number: 20200177957
    Abstract: Method performed by a first node (101). The method is for handling a digital media content. The first node (101) determines (203), automatically, a segment of the digital media content to be of interest to a first user of a second node (102) providing the digital media content to the first user. The determining (203) is based on an analysis of collected data on seeking of the digital media content by at least one second user. The seeking has been performed in points in time in the digital media content. The points in time have been freely chosen by the least one second user from an entire duration of the digital media content. The first node (101) then initiates (204) providing a first indication of the determined segment of the digital media content to be of interest to the first user, to at least one of: the second node (102), and another node (103, 104).

  • Publication number: 20200066281
    Abstract: AM and LM parameters to be used for adapting an ASR model are derived for each audio segment of an audio stream comprising multiple audio programs. A set of identifiers, including a speaker identifier, a speaker domain identifier and a program domain identifier, is obtained for each audio segment. The set of identifiers are used to select most suitable AM and LM parameters for the particular audio segment. The embodiments enable provision of maximum constraints on the AMs and LMs and enable adaptation of the ASR model on the fly for audio streams of multiple audio programs, such as broadcast audio. This means that the embodiments enable selecting AM and LM parameters that are most suitable in terms of ASR performance for each audio segment.
