  • Patent number: 11689763
    Abstract: Techniques described herein improve viewer experience by leveraging the ability of a viewer's device to access an over-the-top (OTT) content via the device's multi-channel connections to an OTT content server. In an example embodiment, the device receives the OTT content via a first channel and performs cross-party diagnostic testing through a second channel. In this embodiment, a diagnostic app in the device compares measured signals in the first channel with a first set of threshold values and further compares acquired telemetry data in the second channel with a second set of threshold values. Based on the comparison results, the device determines the possible root cause of the interruption. Further, the device performs an in-depth diagnostic testing on a determined possible root cause (e.g., OTT content server) and sends an in-depth diagnostic report to a viewer.

  • Patent number: 11641618
    Abstract: A cell access method includes determining a cell type of a first cell as a cell served by a high-speed-railway dedicated network or a cell of an ordinary Long-Term Evolution network. When determining the cell type as the cell served by the dedicated network, a first system message is configured and includes a first information unit indicating a number of equivalent cells, and sent to a terminal for determining, according to the first system message, that the cell type of the first cell is the cell served by the dedicated network. Upon determining a terminal movement state meeting preset access conditions of the cell served by the dedicated network, an access to the first cell is initiated. As such, the accuracy of terminal movement state can be predicted in accordance with the number of equivalent cells to the first cell, and the accuracy of cell access can be further improved.

  • Patent number: 11620679
    Abstract: Aspects of the disclosure relate to monitoring and using telemetry information in various ways. For example, a system that monitors telemetry information may include a user that gathers telemetry information of a device and transmits the information to a monitored room. A manager may join a monitored room and monitor the monitored room for particular types of telemetry information. In one example, a manager may determine whether a downstream device is experiencing a network problem, such as a low bitrate. A manager may also transmit commands to the player via the monitored room, which causes the downstream device to operate in accordance with the transmitted command. In one example, a manager may transmit a command that causes a player to decode a particular service.

  • Patent number: 11617119
    Abstract: The disclosed technology proposes a new methodology to include the effect of speed and direction of a UE into the threshold used for determining when to switch between a 4G UL connection and a 5G UL connection. The system can use a lookup table with various speeds mapping to varying thresholds. The system can use an accelerometer sensor or digital compass to determine the direction of the vehicle, such as heading away from or toward the 5G site, so the vehicle can switch sooner from 5G-NR to LTE and from LTE to NR, respectively. For C-V2X applications, latency is an important factor because 5G technology provides shorter latency than 4G; thus keeping the link on 5G is preferred when under good coverage. Further, the idea is not limited to UL, 5G and/or vehicle technologies, but can also be applied to DL direction, Wi-Fi and/or drone technologies as well.
