  • Patent number: 11347264
    Abstract: A device for handheld operation is provided. The device comprises a touchscreen and processing means operative to display a plurality of user-interface (UI) elements on the touchscreen, wherein each UI element is associated with an action which is performed in response to touching the UI element, determine one or more of the displayed UI elements which a user of the device is likely to touch based on a touch pattern, and perform, for at least one of the determined UI elements, the action associated with the UI element. The action may, e.g., comprise pre-fetching content which is likely to be requested by the user from a server. Performing an action, such as pre-fetching, based on a touch pattern is advantageous since a touch pattern reflects the relative likelihood that the user touches a specific position, or region, of the touchscreen, thereby reducing latency.

  • Publication number: 20210273888
    Abstract: A method and a communication device (200) for controlling reception of data when a maximum total amount of received data is stipulated for a time period. An amount of data received during said time period is monitored (2:5) and compared with a predicted distribution of data (200A) that the device (200) is expected to receive without exceeding the maximum total amount. An amount of requested data is then reduced (2:6, 2:7) when detecting that the monitored amount of received data exceeds the predicted distribution of data, so that the maximum total amount of data will not be exceeded before the time period expires.

  • Patent number: 9743306
    Abstract: The invention relates to a method for performance reporting in a wireless network, wherein at least one terminal is associated to a terminal report server by means of information in the terminal. Prior to initiating the performance report, information on operator identity is retrieved. The operator identity is combined with information identifying the associated terminal report server to compile a fully qualified domain name. Connectivity information to the terminal server report is requested and received from a domain name server, whereupon a performance report session to the terminal report server is initiated using the received connectivity information. The invention also relates to a terminal wherein the inventive method is applied.

  • Patent number: 9203708
    Abstract: One or more embodiments herein dynamically and objectively estimate user-perceived quality of an encoded video stream in dependence on the underlying video content of that stream. Estimation processing according to these embodiments includes generating a chronological sequence of the absolute or relative sizes of encoded video frames in the stream. Processing further entails analyzing this sequence to identify a plurality of reference characteristics that are defined in a reference model. These reference characteristics are more specifically defined in the reference model as parameters that characterize or are otherwise associated with content-dependent variations in user-perceived quality. For example, the reference characteristics in some embodiments comprise reference patterns or reference statistical measures that have been determined based on analyzing frame size sequences generated for reference video streams with known qualities.
