  • Patent number: 10728850
    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.

  • Patent number: 10681665
    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.

  • Patent number: 10602483
    Abstract: Embodiments relate to apparatus, systems, and methods for reception of calls on a mobile device that includes Wi-Fi and cellular radios. The mobile device may be configured to establish communication on a Wi-Fi network with a cellular carrier. The mobile device may further be configured to register a first IP address with an IMS server for the Wi-Fi network communication and register a second IP address with the IMS server for the cellular network communication (or register different ports of a single IP address with Wi-Fi and cellular). Upon occurrence of a mobile terminating call from the cellular carrier, the mobile device may receive an incoming call notification on one or both of the Wi-Fi network using the first IP address and the cellular network using the second IP address.

  • Patent number: 10595252
    Abstract: Methods and systems are disclosed for performing seamless voice call handover and data handoff between a cellular network and a non-cellular (e.g., Wi-Fi) network, by a link budget limited user equipment device (UE) in standalone mode. The cellular radio may be maintained in a non-communication mode when not in use, to prevent power and peak power issues that may be unique to link budget limited devices. In response to poor non-cellular performance in support of a voice call, the UE may transition the cellular radio from the non-communication state to an online state. If the cellular network indicates that packet-switched calls are supported, then the UE may initiate handover of the voice call to the cellular network. Various methods for seamless handoff of data communications are also disclosed, in both the presence and the absence of a voice call. Various metrics are disclosed to enhance handoff determinations.

  • Publication number: 20200084723
    Abstract: This disclosure relates to dynamic baseband management for a wireless device. The wireless device may be an accessory device. The accessory device may determine whether it has a short-range wireless communication link with a companion device. The accessory device may determine one or more proximity metrics relating to the companion device. 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.

  • Publication number: 20200059988
    Abstract: This disclosure relates to techniques for adaptive C-DRX Management. A wireless device and a cellular base station may establish a cellular link. According to some embodiments, the base station may monitor upcoming traffic with the wireless device. Based at least in part on the upcoming traffic for the wireless device, the base station may provide a command indicating to the wireless device to enter C-DRX. The command may further indicate to the wireless device a number of C-DRX cycles through which to remain in a low power state.

  • Patent number: 10567569
    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.

  • Publication number: 20190312868
    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.

  • Patent number: 10440641
    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.

  • Publication number: 20190141137
    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.
