  • Patent number: 11382017
    Abstract: A device providing inter-device call continuity facilitated by a wireless audio output device may include a processor configured to initiate, over a peer-to-peer connection with a second device, a communication session between the second device and a third device. The processor may be further configured to establish, over the peer-to-peer connection with the second device, an audio link corresponding to the communication session. The processor may be further configured to determine, based at least in part on the audio link, that a connection quality of the peer-to-peer connection satisfies a connection degradation condition. The processor may be further configured to request, over a wide area network connection, for the communication session with the third device to be handed-off from the second device to the first device, and to establish, over the wide area network connection, the communication session with the third device.

  • Patent number: 11206701
    Abstract: Apparatus and methods to support access to services of multiple wireless networks by a single-radio, multiple subscriber identity module (SIM)/electronic SIM (eSIM) wireless device are disclosed. To send or receive voice communications for multiple SIMs/eSIMs, when an active voice connection for a first SIM/eSIM uses wireless circuitry to connect to a first cellular wireless network via a first radio access network, the single-radio, multi-SIM/eSIM wireless device uses alternative data transports, such as via a wireless local area network (WLAN) or by tunneling through the first radio access network of the first cellular wireless network to connect to services of additional cellular wireless networks associated with the multiple SIMs/eSIMs.

  • Patent number: 11206582
    Abstract: Embodiments for performing a fast return to Wi-Fi following completion of a cellular voice call are provided. These embodiments include detecting that a device has switched from communicating over a Wi-Fi interface to communicating over a cellular interface; determining the earliest time that the device can switch back to Wi-Fi; and instituting the switch. In some embodiments, the process of performing a fast return to Wi-Fi is carried out by devices having small form factors, such as smartwatches and other wearables, which may be susceptible to coexistence and peak power problems. The fast return to Wi-Fi embodiments disclosed herein allow a device to perform a voice call over a cellular interface when Wi-Fi calling is not available, and switch over to a Wi-Fi interface immediately upon completion of the voice call in order to conserve battery life, achieve higher data speeds, and avoid high costs associated with cellular data transmissions.

  • Publication number: 20210392548
    Abstract: This disclosure relates to techniques for a wireless device to detect network bandwidth throttling and dynamically select a buffer threshold. The wireless device may establish a wireless link. Data for a downlink stream may be requested when an amount of buffered data for the stream is below a lower buffer threshold, received via the wireless link, and buffered. Data requests for the stream may be stopped when the amount of buffered data for the stream is above an upper buffer threshold. The upper buffer threshold may be selected based on characteristics of the wireless link and the stream. Throughput of the wireless link may also be monitored during multiple time windows, and the wireless device may determine whether the wireless link caps bandwidth below a bandwidth threshold based on the throughput monitoring.

  • Publication number: 20210377983
    Abstract: A system and method for operation of a user equipment (UE) to determine a cellular network bottleneck in a downlink channel, and an apparatus for use in a UE for determining the same. A UE may determine a burst of network traffic from network traffic received from the cellular network during a series of transmission time intervals. The UE may analyze resource allocations to the UE during the burst to determine an extent to which the cellular network is busy. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the analysis of the resource allocations to the UE in the burst.

  • Publication number: 20210282127
    Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A wireless device can monitor application workloads by analyzing communication network performance requirements for a given application in-use or launching for future use along with system-level indications of overall device usage, battery level, and mobility status to determine whether access to 5G cellular baseband resources is recommended for an application. A 5G cellular baseband resource recommendation is provided for an application indicating a level of bandwidth in current use or expected for future use as well as a confidence metric in the bandwidth level indication. The 5G cellular baseband resource recommendation is used with additional device criteria to determine whether access to one or more 5G radio frequency bands is allowed.

  • Patent number: 10932223
    Abstract: Signal load due to ping-pong of a wireless device between a wireless local area network (WLAN) access point (AP) and a cellular base station is reduced. The wireless device operates in a geographic region with signal coverage from more than one radio access technology (RAT) type of cellular serving cell as well as potentially coverage from the AP. An IP address used for incoming calls and the RAT serving the wireless device are part of a context. In some instances, when the wireless device changes context from the AP to a cellular base station and back to the AP (“ping-pong”), the context changes and a new IP address may be obtained via network signaling. Ping-pong is reduced by determining a quality estimate of cellular signals that relies on cell measurements from a mix of cellular base stations, where the mix of cellular base stations supports different cellular RATs.

  • Patent number: 10880379
    Abstract: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.
