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: 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.

Abstract: A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

Abstract: A user equipment (UE), base station and a corresponding method for receiving historical data from a diagnostic server, receiving location data of the UE, determining a probability of a failed handover during a call based on the historical data and the location data, comparing the probability of the failed handover to a threshold value and initiating a call handover to a wireless local area network when the probability of the failed handover exceeds the threshold value. Also, a UE, base station and corresponding method for determining if one or more UEs have an active voice over WiFi call or if the UEs are registered with a Internet protocol (“IP”) multimedia subsystem (“IMS”) over WiFi and biasing a cell reselection procedure of the UE to select a cell of a packet switched network such as LTE.

Abstract: A connected car and an onboard user equipment (UE) may establish independent cellular connections and may also establish a connection between each other. The UE establishes a first cellular link between the UE and a first network, establishes a connection with a connected car, wherein the connected car has a second cellular link between the connected car and a second network, evaluates one or more conditions and declares one of the first cellular link or the connection with the connected car a primary network interface for the UE based on, at least, the one or more conditions.

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.

Abstract: Apparatus and methods to support authentication failure handling by network elements and by a wireless communication device when attempting access to services through non-cellular wireless networks by the wireless communication device are disclosed. Error messages received from evolved packet core (EPC) network elements, such as an authentication, authorization, and accounting (AAA) server, are mapped to failure messages provided to wireless communication devices by internetworking equipment, such as an evolved packet data gateway (ePDG). The wireless communication device determines a failures cause based on the failure messages and disallows retry attempts until select criteria are satisfied.
