Abstract: This Application sets forth techniques for managing the cellular connectivity state of a submerged wireless device. The wireless device can include sensors that analyze environmental conditions to determine when the wireless device is (or is not) submerged underwater as well as at what depth the wireless device is submerged underwater. The sensors can also determine different types of aquatic activity in which a user of the wireless device is currently engaged, such as swimming, snorkeling, free diving, and scuba diving. In turn, the wireless device can utilize this information to manage its cellular connectivity state in order to avoid wasteful consumptions of energy. In particular, the techniques enable the submerged wireless device to eliminate any existing cellular connection as well as connection reattempts so long as they are unlikely to succeed. Moreover, the techniques enable the wireless device to execute connection reattempts when they are appropriate and likely to succeed.

Abstract: A device executing a low-latency application that uses a Wi-Fi link may switch from the Wi-Fi link to using a second link to a multi-subscriber (MSIM) PHS device. The device may access, via the second link, any one of multiple cellular links, each cellular link corresponding to a different respective cellular subscription of multiple subscriptions used by the PHS device. The application executing on the device may thus use a preferred cellular link from among the multiple cellular links. The preferred cellular link may be determined based on parameters corresponding to the plurality of cellular links for each respective cellular subscription. The parameters may be obtained from a location database. The preferred cellular link (which may presently correspond to a primary subscription) on the PHS device may be switched to be a different cellular link (which may correspond to a non-primary subscription) during execution of the application on the device.

Abstract: Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.

Abstract: Techniques described herein may enable a user equipment (UE) to optimize radio access technology (RAT) and radio resources (e.g., bandwidth parts (BWPs)) when communicating with the network. This may be based on one or more factors or conditions, such as whether the UE is currently using 4th generation (4G) RAT or 5th generation (5G) RAT, whether the UE is in an active mode or idle mode, a BWP used by the UE, whether an application or network service requires a certain throughput, a type of application being used by the UE, an amount of network congestion, and so on. RAT optimization may also be based on whether the UE is using a frequency range 1 (FR1) or frequency range 2 (FR2), whether the UE is stationary or moving, whether the UE is experiencing beam failures, uplink (UL) switches, link quality measurements (LQMs), reference signal received power (RSRP) measurements, and so on.

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.
