    Abstract: This Application sets forth techniques for binding and dynamic provisioning of international mobile equipment identifier (IMEI) values with cellular wireless service profiles, such as subscriber identity modules (SIMs) on physical SIM (pSIM) cards and electronic SIMs (eSIMs) on an embedded universal integrated circuit card (eUICC) of the mobile wireless device. When pSIMs and/or eSIMs change on the mobile wireless device, e.g., based on installation, activation, deactivation, de-installation, etc., IMEI binding logic accounts for the changes and maps IMEI values to pSIMs and/or eSIMs as required. IMEI values can be assigned based on a history of bindings between IMEI values and ICCID values of one or more eSIMS on an eUICC. A most recently used or a newly assigned IMEI value can be associated with an eSIM. Whether to assign an identical IMEI value to multiple eSIMs depends on requirements of associated cellular wireless service subscriptions.

    Abstract: Techniques for flexible electronic subscriber identity module (eSIM) deployment to a wireless device by a network server, including generation of multiple eSIMs using an identical eSIM identifier value, such as an identical integrated circuit card identifier (ICCID) value, and subsequent selection of an eSIM based on capabilities of the wireless device. Multiple eSIMs that correspond to different sets of wireless device capabilities are generated without knowledge of the wireless communication standards that a wireless device supports. The multiple eSIMs include a first eSIM that includes fifth generation (5G) wireless communication protocol information and a second eSIM that excludes 5G wireless communication protocol information. The network server selects an eSIM from the multiple eSIMs based on whether the wireless device is 5G capable. After selection and binding of a profile package that includes the eSIM, the remaining eSIMs that use the identical ICCID value are deleted, for security enforcement against cloning.

    Abstract: Embodiments described herein relate to managing access to an embedded universal integrated circuit card (eUICC) to obtain subscriber identity module (SIM) information without requiring cellular baseband wireless processing support. A baseband component of a wireless device that connects to the eUICC via a first interface can be in a reduced power state, and under certain conditions a processor external to the eUICC can access the eUICC via a second interface without booting up the baseband component to a normal (full) power state. When access to the eUICC via the first interface through the baseband component is required, the baseband component can be booted to a normal (full) power state to communicate with the eUICC. Additionally, a wireless device in which the baseband component is in a reduced power state or is absent can access one or more services of a mobile network operator (MNO) via a non-cellular wireless interface.

    IPC: H04W8/20

    Abstract: The described embodiments set forth techniques for recovering one or more electronic subscriber identity modules (eSIMs) previously deleted from an embedded universal integrated circuit card (eUICC) of a mobile wireless device. Prior to deletion of an eSIM, the mobile wireless device uploads first eSIM subscription information to a cloud network services server and stores second eSIM subscription information in a secure memory of the eUICC. The mobile wireless device can subsequently download the first eSIM subscription information to verify matching to the second eSIM subscription information stored in the eUICC before displaying an option for recovering the eSIM. The mobile wireless device sends to a mobile network operator (MNO) provisioning server an eSIM recovery request notification that includes at least a portion of the first eSIM subscription information, and the MNO provisioning server provides an eSIM recovery response message indicating approval and a network address to download the eSIM.

    Abstract: This application describes a phased approach to provision eSIM profiles to a wireless device. Credentials are preloaded to an eUICC during manufacture of the eUICC and used subsequently to load eSIM profiles to the eUICC without requiring an active, real-time connection to an MNO provisioning server. Multiple bound profile packages (BPPs) can be pre-generated and encrypted by MNO provisioning servers for an eUICC and transferred to a BPP aggregator server before assembly of the eUICC in a respective wireless device. A local provisioning server in a manufacturing facility mutually authenticates and connects to the BPP aggregator server to download and store one or more of the encrypted BPPs for later installation on the eUICC. The local provisioning server subsequently mutually authenticates and connects to the eUICC to load at least one of the one or more pre-generated, encrypted BPPs to the eUICC during assembly and/or testing of the wireless device.

    Abstract: Techniques for managing logical channel communication for multiple electronic subscriber identity module (eSIM) profiles installed on an embedded universal integrated circuit card (eUICC), including mapping of logical channel identifier values between different logical channel labeling schemes are described herein. In a first scheme, logical channels are identified using logical channel values alone. In a second scheme, logical channels are identified using a combination of eSIM port value and channel values. An interpreter in the eUICC and/or in processing circuitry external to the eUICC can map between the logical channel labeling schemes to allow internal state machines in the eUICC and/or the processing circuitry to use the first scheme for identifying logical channels.

    Abstract: This application sets forth techniques for authenticating a mobile device with a cellular wireless network without electronic Subscriber Identity Module (eSIM) credentials by using an Extensible Authentication Protocol Transport Layer Security (EAP-TLS) procedure. The mobile device authenticates with an Authentication Server Function (AUSF) of the cellular wireless network using an embedded Universal Integrated Circuit Card (eUICC) certificate. Processing circuitry of the mobile wireless device external to the eUICC implements the EAP-TLS procedure and authenticates validity of the AUSF. In some embodiments, the eUICC provides key generation and storage for a session key for communication between the mobile device and the cellular wireless network. In some embodiments, a third-party managed Unified Data Management (UDM) broker authenticates the mobile device based on knowledge of the eUICC certificate and provides a session key to the cellular wireless network for subsequent communication with the mobile device, upon successful authentication of the mobile device.
