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.

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: A wireless communication device (UE) may perform wireless communications according to at least a first radio access technology (RAT) and a second RAT. When the UE is in idle-mode, it may determine whether to bias a RAT selection policy—which may be presently favoring networks operating according to the first RAT—towards the second RAT, based on one or more of the following: first information indicative of a quality of previous wireless communications performed by the UE according to the first RAT, second information indicative of an overall quality of wireless communications performed according to the first RAT by the UE over a specified period of time at a specific location where the UE is presently located, and/or third information indicative of an overall quality of wireless communications performed according to the first RAT by other UEs presently located at the specific location.

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: 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: A client device and a host device may create a local connection for providing wide area network access, such as Internet access, to the client device. In some embodiments, the client device may have limited network capabilities and may not be able to access the Internet without the host device. The client device may provide its speed and direction in a message to potential host devices. A host device may calculate a suitability metric, based on the speed and direction of the client as well as connection properties of the networks, which indicates an ability for the host device to connect the client device to the Internet. The host device may provide the suitability metric within a connection request to the client device. Based on the suitability metric and/or other factors, the client device and the host device may establish the local connection.

Abstract: Apparatus and methods to support location specific control to allow and/or disallow access to services through untrusted wireless networks by a wireless communication device are disclosed. One or more network elements obtain a location of the wireless communication device and selectively allow and/or disallow access to one or more cellular network services and/or one or more access point names (APNs) based on the location of the wireless communication device when connecting through an untrusted wireless network.

Abstract: In some embodiments, a cellular baseband processor communicates wirelessly and reports cellular metrics for both a first cellular RAT and a second cellular RAT. The cellular baseband processor may be configured to tune away, for a time interval, from the first cellular RAT to monitor for communications on the second cellular RAT. In some embodiments, the cellular baseband processor is configured not to report cellular metrics during the time interval to prevent a RAT manager from setting up a connection for voice calls on a WLAN RAT during the time interval. In some embodiments another processing element the RAT manager is configured to ignore cellular metrics from the cellular baseband processor during the interval. This may reduce signal load and power consumption, in some embodiments.

Abstract: A user equipment (UE) device may be configured to effectively manage coexistence of multiple radio access technologies (RATs) on the device. Respective controllers responsible for at least partially managing wireless communications according to corresponding respective RATs may communicate to each other expected data transfer patterns that take place over their respective communications links, including application-specific data transfer patterns and data-transfer-mechanism-specific data transfer patterns. The RAT controllers may manage their respective data transfers according to the expected data-transfer pattern information associated with the other RATs received from each in order to prevent data transmission by the device over one RAT link interfering with data transmission of the device over another RAT link.

Abstract: This disclosure relates to inter radio access technology management for audiovisual calls. Wireless link availability and suitability for an audiovisual call may be evaluated for each of a first radio access technology and a second radio access technology. One or more wireless links on which to establish an audiovisual call may be selected based on the evaluations. The audiovisual call may be established on the selected wireless link(s). Wireless link availability and suitability for an audiovisual call may be monitored during the audiovisual call and decisions on whether to perform handover to a different wireless link and/or media duplication on multiple wireless links may be made based on the suitability for an audiovisual call of available wireless links.
