  • Publication number: 20240058694
    Abstract: A method (400) for selecting from a set of two or more available PUs (e.g. a set of GPUs or a set of TPUs) a PU to serve a UE (102) (i.e., select the “best” PU for the UE). The set of available PUs includes at least a first PU and a second PU. The method includes, for each PU included in the set of available PUs, obtaining (s402) performance information for the PU. The performance information for the first PU comprises a first time value indicating an estimated amount of time that it will take the first PU to produce a first result. The method also includes obtaining (s404) budget information for the UE, wherein the budget information comprises a threshold time value indicating a threshold amount of time. The method further includes selecting (s406) a PU from the set of available PUs based on the stored performance information and the budget information for the UE.

  • Publication number: 20230239655
    Abstract: A geofencing system (310) that does not rely on a GNSS or other like system. The geofencing system comprises a group of two or more fence-pole devices, FPDs, that define a geofenced area (399). Each FPD in the group is capable of making its own determination as to whether or not a certain communication device (377, 378) appears to be within the geofenced area. In one embodiment, if all of the FPDs have determined that the communication device appears to be within the geofenced area, then it is decided that the communication device is within the geofenced area. In another embodiment, if the group of FPDs consists of N FPDs and at least N?1 of the FPDs have determined that the communication device appears to be within the geofenced area, then it is decided that the communication device is within the geofenced area.

  • Patent number: 11606655
    Abstract: A mobile electronic device (device) operating with other devices form a group for wireless coordinated playout of audio media content. The processor performs operations that determine a common time sync shared with the other devices, and determine a timing of occurrence of a sound transient sensed relative to the common time sync. The operations receive timing reports from the other devices, where each of the timing reports indicates a timing of occurrence of the sound transient sensed at a respective one of the other devices relative to the common time sync. The sound transient sensed by the devices is generated at a preferred listening location. The operations coordinate timing of playout of audio media content by the group of devices responsive to comparison of the timing of occurrence of the sound transient sensed by the microphone of the device and the timing of occurrences indicated by the timing reports.

  • Patent number: 11463742
    Abstract: Mechanisms for predicting a multimedia session MOS are provided. The multimedia session has a video session and an audio session. The video quality and the audio quality are represented by vectors of per-time-unit scores of video quality and audio quality, respectively. The multimedia session is represented by a vector of the rebuffering start times of each rebuffering event, and a vector of the rebuffering durations of each rebuffering event. Audiovisual quality features are generated from the vectors of per-time-unit scores of video and audio quality. Buffering features are generated from the vector of rebuffering start times of each rebuffering event and the vector of rebuffering durations of each rebuffering event. A multimedia session MOS is then estimated based on the generated audiovisual quality features and the generated buffering features.

  • Publication number: 20220164154
    Abstract: A mobile electronic device (MD) operates with an arrangement of MDs to provide a virtual playout screen for visual media. A movement sensor senses movement of the MD. Processor operations include generating a movement vector identifying direction and distance that the MD has been moved from a reference location to a playout location where it will form a component of the virtual playout screen, based on tracking movement indicated by the movement sensor while being moved. The operations provide the movement vector to a media splitting module that determines how to split the visual media into a set of cropped portions for display on assigned ones of the MDs based on the movement vector. The operations obtain a cropped portion of the visual media that has been assigned by the media splitting module to the MD, and display the cropped portion of the visual media on a display device.

  • Publication number: 20210377822
    Abstract: Decision-making equipment (22) is configured for link change decision-making using reinforcement learning. The decision-making equipment (22) is configured to track rewards (30-1, . . . 30-M) earned for, and outcomes (28-1, . . . 28-M) of, respective link change decisions (26-1, . . . 26-M). In some embodiments, possible outcomes of a link change decision to change a serving link of a wireless device to a target link include at least: a change of the serving link of the wireless device from the target link to another link; and a network-initiated disconnect of the wireless device from the target link. Regardless, the decision-making equipment (22) is also configured to make a link change decision (28-(M+1)) based on the tracked rewards (30-1, . . . 30-M) and outcomes (28-1, . . . 28-M).

  • Publication number: 20210234941
    Abstract: According to an aspect, a wireless device receives (302) a preview digital image from a computer server and applies object recognition processing (304) to the preview digital image, to determine (306) whether the preview digital image contains a representation of a known object of interest. Responsive to a positive determination, the wireless device transmits (308) an indication of the positive determination. The computer server sends, in response to the transmitted indication, an enhanced digital image corresponding to the preview digital image, or additional image data, which is received (310) by the wireless device. In the latter case, the wireless device forms an enhanced version of the preview digital image using the additional image data. The wireless device at least temporarily stores (312) the enhanced image or image version, e.g., for rendering on a display screen of the device.
