  • Patent number: 10405274
    Abstract: Information is determined affecting data presentation of part of a data stream to a user application on a UE, and may be EC information and/or QoE information caused at least by the data presentation. The information is sent from the UE toward a content server from which the data stream is received by the UE. At radio network element(s), radio timer information corresponding to data transmission of part of the data stream from a base station to a UE is determined and sent (e.g., possibly with the energy consumption information and/or QoE information) to other radio network elements and/or to the content server. The content server can adjust streaming strategy of the data stream based on the information received, and the radio network element(s) can perform power aware scheduling and/or radio timer adjustments based on received EC information and/or the QoE information.

  • Patent number: 10136443
    Abstract: Various systems and devices may benefit from cooperative resources management. For example, third and fourth generation wireless networks may benefit from a mechanism and apparatus to perform cooperative resource management, for example, for video downloads. Various methods are possible. For example, a method can include regulating fill and drain phases for a downloading session, to meet just in time delivery. The regulating can be performed by a user equipment based on parameters provided by a network. Another method can include providing parameters to a user equipment and instructing the user equipment with respect to regulating fill and drain phases for a downloading session, to meet just in time delivery, based on the parameters.

  • Publication number: 20170156071
    Abstract: The invention allows network assisted alternate coverage in a cellular communications network during at least partial cell outage event or a maintenance event. In response to an indication of an at least partial cell outage event or a maintenance event, a mobile communications device is switched from a cellular communications mode to a device-to-device, D2D, communications mode based on D2D configuration information received from a cellular network base station. Communications are performed as needed in the D2D communications mode by the mobile communications device. In response to receiving a message to switch back to the cellular communications mode, the mobile communications device is switched back to the cellular communications mode.

  • Publication number: 20160173489
    Abstract: Various communication systems may benefit from ways of communicating in the absence of a centralized authority. For example, certain wireless communication systems may benefit from victim to victim communication using over-the-top (OTT) identities in a disaster device-to- device (D2D) scenario. A method can include authenticating with an authentication server of an over-the-top service. The method can also include storing an identity certificate upon receiving the identity certificate from an identity server of the over-the-top service. The identity certificate can be configured to provide credentials of the over-the-top service when a centralized authentication authority of the over-the-top service is unavailable.
