  • Publication number: 20190273673
    Abstract: Technologies for link capability estimation are disclosed. A compute device may determine a maximum radio bitrate for a certain connection, such as an LTE connection to a specific cell antenna. The compute device may also determine a maximum downlink bitrate for that connection, and store both the maximum radio bitrate and the maximum downlink bitrate in a database on the compute device. At a later time, an application of the compute device may want to know an estimate of the current maximum downlink bitrate, such as for the purpose of selecting a bitrate in streaming a video. The compute device can determine the current maximum radio bitrate, and look for similar entries in the database. Based on entries in the database, a link capability estimation can be determined and provided to the application.

  • Patent number: 10306182
    Abstract: A user equipment (UE) and method of improving video call quality during handover are generally described. After determining that handover has started (306), the UE may suspend (308) frame transmission and store the frames. After determining that handover has completed (310), the UE may discard (312) frames whose age exceeds a predetermined percent of a latency deviation computed from a real-time transport control protocol report. The UE may determine whether transmission of the remaining frames would exceed a delay proportional to a video frame interval multiplied by an uplink bandwidth for a cell to which the UE is connected or a maximum bitrate of a guaranteed bitrate bearer multiplied by a typical period for a non-access stratum bandwidth and discard frames in order of decreasing age until neither the bitrate nor the delay is exceeded by the transmission.

  • Patent number: 10271374
    Abstract: The UE VoIP engine monitors the network pattern periodicity and implements a scalable scheduling strategy that can adapt the VoIP engine and audio driver scheduling to the current local radio configuration in one embodiment. By adapting its scheduling, the VoIP engine can reduce mouth-to-ear delay or power consumption without impacting the audio encoding quality. The UE VoIP engine sends some scheduling preference to the network base station. The network base station monitors UE preferences and decide whether to ignore or accept UE preferences and allows the UE to operate in the conditions that provides the best tradeoff between power consumption and mouth-to-ear delay.

  • Patent number: 9787742
    Abstract: A user equipment device (UE) comprises physical layer circuitry configured to transmit and receive radio frequency electrical signals with one or more nodes of a radio access network, an audio subsystem configured to generate frames of audio data, and processing circuitry. The processing circuitry is configured to calculate a time delay from generation of an audio data frame by the audio subsystem of the UE device to transmission of an audio data packet by the physical layer circuitry during a voice call, and decrease the time delay to a delay value that preserves a specified minimum time for delivery of the generated audio data frame to the physical layer circuitry to meet a scheduled transmission time of the audio data packet.

  • Patent number: 8213343
    Abstract: A method of and apparatus for communication of conversational data signals, especially voice signals, between transceiver terminals over a radio link, especially a Bluetooth link, capable of full-duplex transmission of conversational data packets in alternate directions within a pair of time slots. Local conversational activity is detected at each of the terminals and conversational activity signals indicative of the detected local conversational activity are sent to the other terminal. Reception at either terminal is disabled if conversational activity signalling indicates absence of remote conversational activity, and transmission by either terminal is disabled in the absence of local conversational activity, saving power. Audible comfort noise may be generated at the terminal from a locally generated comfort noise signal if reception is disabled in response to the conversational activity signalling indicating absence of remote conversational activity.
