  • Patent number: 10893451
    Abstract: A method by a coordination node is provided for controlling communications between Li-Fi APs and UEs. The method includes receiving peer connectivity reports from Li-Fi APs which identify Li-Fi APs having at least partially overlapping coverage areas, and developing a handover pathway data structure, based on the peer connectivity reports, that identifies Li-Fi APs that can receive communication handover from other identified Li-Fi APs. The method further includes determining an identifier of a first Li-Fi AP providing Li-Fi communication service for a UE, and accessing the handover pathway data structure using the identifier of the first Li-Fi AP to determine an identifier of a second Li-Fi AP to which handover from the first Li-Fi AP can be performed. The method then initiates handover of the Li-Fi communication service for the UE from the first Li-Fi AP to the second Li-Fi AP.

  • Patent number: 10887820
    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.

  • Publication number: 20200382958
    Abstract: A method by a WiFi AP for setting-up a WiFi connection with a wireless device, includes sending WiFi service credentials to a Light Fidelity (Li-Fi) AP for transmission through Li-Fi signaling that is broadcast for reception by wireless devices. The method receives and authenticates an authentication request that is received via a RF transceiver of the WiFi AP from the wireless device, which is responding to the WiFi service credentials that were broadcast through the Li-Fi signaling. The method then establishes a WiFi RF connection with the wireless device responsive to the authentication.

  • 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: 20200177277
    Abstract: A method by a coordination node is disclosed for controlling communications between visible Light Communication, VLC, Access Points, AP, and User Equipments, UEs. The method includes identifying occurrence of an event relating to operation of a first VLC AP. The method further includes determining that a second VLC AP and a third VLC AP each have communication coverage areas that are at least partially within a communication coverage area of the first VLC AP, responsive to identification of occurrence of the event. The method then controls the second and the third VLC APs responsive to the determination to avoid their interfering with communications between the first VLC AP and any UEs within common communication coverage areas of the second or the third VLC APs. Related coordination nodes are disclosed.

  • 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: 20200128103
    Abstract: A first network node, a client device and methods therein, for enabling acquisition and delivery of a resource to the client device in a communications network. When receiving from the client device a meta interest request indicating an interest for a wanted resource, the first network node extracts from the meta interest request one or more filter parameters related to desirable characteristics of the wanted resource. The first network node then obtains identifiers of resources available in the communications network, based on the one or more filter parameters, and sends the obtained identifiers of resources to the client device in response to the received meta interest request. Thereby, a user of the client device can see which resources with the desirable characteristics are available in the network and acquire one of the resources identified in this way, without having to specify the supplier nor the resource in the initial request.

  • Publication number: 20190356575
    Abstract: Embodiments herein relate to a method performed by a communication node for handling packets in a communication network, which communication network is an ICN network. The communication node adds a time stamp to a packet, which packet is requesting content of a service or comprises at least a part of the content of the service and is of a format associated with the ICN network, and which time stamp is added into an ICN header of the packet. Furthermore, the communication node transmits the packet with the added time stamp towards another communication node.

  • Publication number: 20190312819
    Abstract: A method performed in a network node for handling an Internet Protocol, IP, packet. The IP packet originates from a source node and addresses to a destination node in an IP communication network. Upon receipt of the IP packet, the network node decapsulates the IP packet to obtain, from a network layer header of the IP packet, an indication of a point in time to drop the IP packet. The point in time to drop the IP packet is based on a first maximum delay of the IP packet between the source node and the destination node. The first maximum delay was obtained from an application software running on the source node. The network node determines whether or not to drop the IP packet based on the indication, using a clock of the network node synchronized with a clock of the source node.

  • Patent number: 10404856
    Abstract: A method and a call manager node (200) for handling calls directed to a group of subscribers. When receiving (2:3) a request from a caller (202) for access to a first group of subscribers (204) having at least one common characteristic, the call manager node assigns (2:4) first caller-specific temporary group number (A1) for the caller, wherein the first group number can be used exclusively by the caller for calling the subscribers in the first group. The call manager node further sends (2:5) the first group number to the caller in response to the request. The caller is then connected (2:7, 2:9, 2:11) to a subscriber in the first group sequentially or according to a scheme each time the caller dials (2:6, 2:8, 2:10) the first group number. The group is created according to a criteria and the anonymity of the called parties is kept. Call hunting.
