    Abstract: This disclosure relates to techniques for a wireless device to autonomously perform certain cell measurements in a wireless communication system. A wireless device may establish a wireless link with a cellular base station. The wireless link may be established according to a first radio access technology. The wireless device may determine whether at least one cell that operates according to a second radio access technology is available at the current location of the wireless device based on information stored by the wireless device. If at least one cell that operates according to the second radio access technology is available, the wireless device may perform one or more cell measurements on a cell that operates according to the second radio access technology.

    Abstract: A self-organizing device may include a recovery control module which may monitor different events from various different domains, for example from different layers of the software stack, associated with wireless communications of the device. Upon identifying a specific condition based on the monitored information, the device may execute a corresponding auto-recovery mechanism to mitigate adverse effects of the condition experienced by the device. Devices may provide monitored information to servers, e.g. to cloud servers, which may use expert systems to analyze the information collected from multiple devices, for example from globally dispersed devices, and may define mitigation action responses corresponding to specific scenarios or conditions that include device-specific considerations. The mitigating action responses may be deployed to the devices by the servers as expert system rules in the form of uncompiled code or hot patch code that the devices may later use to implement the necessary mitigation actions as warranted.

    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.

    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.

    Abstract: This disclosure relates to wireless connection management for an accessory device. A companion device and the accessory device may establish a wireless link. The companion device may associate with a Wi-Fi access point. The companion device may determine whether the Wi-Fi access point supports access by the accessory device to a wide area network. The companion device may determine whether to provide association information for the Wi-Fi access point to the accessory device based at least in part on whether the Wi-Fi access point supports access by the accessory device to the wide area network. The companion device may monitor whether the Wi-Fi access point continues to support access by the accessory device to the wide area network, and may indicate to the accessory device to disassociate with the Wi-Fi access point if the Wi-Fi access point no longer supports access by the accessory device to the wide area network.
