  • Publication number: 20240080654
    Abstract: This application sets forth techniques for dynamically managing a provisioning electronic subscriber identity module (eSIM) for a wireless device. A provisioning eSIM is installed in the wireless device to provide a limited functionality connectivity option for essential services, such as device activation and user eSIM provisioning. To reduce signaling load on a network and to conserve wireless device battery power, the provisioning eSIM is reconfigured between an inactive state and an active state dynamically based on user actions and system requirements.

  • Publication number: 20230354040
    Abstract: The described embodiments set forth techniques for management of electronic subscriber identity module (eSIM) profiles for a wireless device, including in-field replacement of provisioning (bootstrap) eSIM profiles. Public key infrastructure (PKI) information for an original equipment manufacturer (OEM) profile management server is installed in an embedded universal integrated circuit card (eUICC) of a wireless device at a time of manufacture and used subsequently by the wireless device to conduct an eSIM profile management session and verify authorization of the OEM profile management server to manage, e.g.

  • Publication number: 20230319573
    Abstract: Embodiments are described herein for transferring a subscriber identity module (SIM) or electronic SIM (eSIM) profile securely from a source device to a target device with verifiable signatures generated by secure hardware elements of the source device contingent on receipt of a secure intent gesture. Trustworthiness of the profile transfer is based on a mobile network operator (MNO) entitlement server releasing a transfer token after verification of a message signed by an embedded universal integrated circuit card (eUICC) of the source device. The eUICC signs the message only after verifying a message from a secure enclave processor (SEP) of the source device that signs the message based on receipt of the secure intent gesture via a secure interface. To validate communication between the SEP and the eUICC, an asymmetric cryptographic key pair generated by the SEP is bound to a unique eUICC identifier (EID) value of the eUICC.

  • Publication number: 20220022028
    Abstract: This Application sets forth techniques for profile, e.g., subscriber identity module (SIM) and electronic SIM (eSIM), and cellular wireless service subscription management for a wireless device. The wireless device can support multiple profiles, such as dual SIMS or a single SIM and one or more eSIMs. A user of the wireless device can flexibly enable and disable various eSIMs or change the use of physical SIMs with different associated cellular wireless service subscriptions, and mapping of subscription modules to logical channels and physical hardware interfaces can occur automatically, with mechanisms to reset interfaces when required.

  • Patent number: 11012852
    Abstract: Embodiments described herein relate to mechanisms for error recovery during transfer of cellular service credentials between two mobile wireless devices. Transfer of credentials includes communication between a source device, a target device, and/or one more network-based servers. Authentication can be based on one or more tokens obtained by the source device and provided to the target device. Error recovery can include using redirection to different servers, providing alternative information for authentication, and storage and subsequent retrieval of information to restart or complete a credential transfer process.

  • Patent number: 9866588
    Abstract: A method at a user equipment capable of supporting at least two radio connections, the method including requesting from a remote server, using a first radio connection, a subscriber identity; receiving, at the user equipment, the subscriber identity over the first radio connection; using the subscriber identity to establish a second radio connection; and forcing the first radio connection to remain on a same network as the second radio connection. Further, a method at a user equipment capable of supporting at least two radio connections, the method receiving a subscriber authentication challenge over the second network connection; using the first radio connection to connect to the remote server to obtain an authentication challenge response for the subscriber authentication challenge; and sending the authentication challenge response over the second network connection.

  • Patent number: 9485340
    Abstract: A telephone station apparatus that is arranged to operate on two, or more, communication lines, receives an instruction to access a voicemail server. The telephone station apparatus switches from a first communication line to a second communication line and initiates a call to the voicemail server. At the voicemail server, calling line identification allows the voicemail server to present an interface to the voicemail box associated with the second communication line.

  • Publication number: 20160021232
    Abstract: Embodiments of a system and method for providing a user interface for managing calls received at a mobile device is described. The user interface provides an incoming call screen to the user, where the incoming call screen comprises a caller identification data field for displaying data associated with incoming calls and at least one key label field in which labels for mobile device keys (e.g. send and end keys) are displayed. The area of the caller identification data field is substantially greater than the area of the at least one key label field, enabling more information pertaining to incoming calls to be displayed to the user. In at least one embodiment, this is facilitated by providing user-selectable options for responding to incoming calls in an options menu, which can be accessed by a user but is not initially displayed to the user when an incoming call is first received.
