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.

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, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

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.

Abstract: Some embodiments relate to a smart phone or a wearable device, such as a smart watch, and associated methods for enabling the UE device to switch from a normal mode to/from a voice-to-text mode and/or a text-to-voice mode. The transition to/from voice-to-text mode and/or text-to-voice mode may be conducted automatically or through manual selection by the user of the UE. These transitions (or the presentation of a manual selection option) may be determined based on an ambient noise measurement performed by the UE.

Abstract: A device, system, and method uses a high power mode for a cellular connection. The method is performed at a device that is configured to establish a network connection to a network. The method includes detecting a number of at least one event that has occurred over a time period, the at least one event associated with operations used through the network connection, the at least one event indicative of a power to perform the operations that is greater than a predetermined power. When the number is at least a predetermined threshold, the method includes identifying the network connection as being in a high power state. The method includes activating settings when the network connection is in the high power state, the settings reducing a usage of the operations over the network connection.

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.

The accessory device may further determine one or more metrics associated with user settings, user activity and/or application activity at the wireless device. The wireless device may select a (e.g., full, limited, or off) baseband operating mode based on any or all of these considerations.

Abstract: Methods and apparatus to enable and disable cellular services for one or more cellular capable secondary wireless devices associated with a primary wireless device are disclosed. The primary wireless device, in response to detecting a status change of an in use state of a cellular capable secondary wireless device can provide a notification to a network server of a wireless network to disable cellular wireless services for previously enabled cellular capable secondary wireless devices and to enable cellular wireless services for the cellular capable secondary wireless device. Control of cellular wireless services for cellular capable secondary wireless devices can be based on a combination of registration for services, activation and deactivation of eSIMs on the cellular capable secondary wireless devices, and/or changes to eSIM states or contexts maintained by the network server.
