Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A wireless device can monitor application workloads by analyzing communication network performance requirements for a given application in-use or launching for future use along with system-level indications of overall device usage, battery level, and mobility status to determine whether access to 5G cellular baseband resources is recommended for an application. A 5G cellular baseband resource recommendation is provided for an application indicating a level of bandwidth in current use or expected for future use as well as a confidence metric in the bandwidth level indication. The 5G cellular baseband resource recommendation is used with additional device criteria to determine whether access to one or more 5G radio frequency bands is allowed.

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.

Abstract: Disclosed herein are techniques for enabling a user to activate a new device with a Mobile Network Operator (MNO) without requiring the user to provide MNO authentication credentials that are easily forgotten. The user activates the new device using credentials from an existing device (associated with the user) that is trusted by the MNO and also using a trust score provided by a third-party server that has knowledge of associations between the user and the existing device. The new device can be a supplemental device, such as a wearable device to a cellular phone, where both devices remain capable of accessing services provided by the MNO after the new device is activated with the MNO. The new device can also be a replacement device, such as a new phone, tablet, or wearable device, where the new device supplants access to services provided by the MNO for an existing device.

Abstract: This disclosure relates to techniques for performing Wi-Fi authentication in a wireless communication system. Public key cryptography may be used to enhance the confidentiality of the user's permanent identity in transit. In some embodiments, a RSA-OAEP(SHA-256) encryption scheme may be used to protect the permanent identity when the EAP client needs to send the user's permanent identity to the server in the absence of pseudonym or fast re-authentication identity. In some embodiments, a server certificate is used to authenticate a iWLAN tunnel to protect an IMSI during setup of a Wi-Fi call. Using the methods described herein on both or either of the EAP client and server side may offer improved privacy protection.

Abstract: Methods and apparatus for user authentication and human intent verification of administrative operations for eSIMs of an eUICC included in a mobile device are disclosed. Certain administrative operations, such as import, modification, and/or export, of an eSIM and/or for an eUICCs firmware can require user authentication and/or human intent verification before execution of the administrative operations are performed or completed by the mobile device. A user of the mobile device provides information to link an external user account to an eSIM upon (or subsequent to) installation on the eUICC. User credentials, such as a user name and password, and/or information generated therefrom, can be used to authenticate the user with an external server. In response to successful user authentication, the administrative operations are performed. Human intent verification can also be performed in conjunction with user authentication to prevent malware from interfering with eSIM and/or eUICC functions of the mobile device.

Abstract: Disclosed herein are different techniques for enabling a mobile device to dynamically support different authentication algorithms. A first technique involves configuring an eUICC included in the mobile device to implement various authentication algorithms that are utilized by MNOs (e.g., MNOs with which the mobile device can interact). Specifically, this technique involves the eUICC storing executable code for each of the various authentication algorithms. According to this technique, the eUICC is configured to manage at least one eSIM, where the eSIM includes (i) an identifier that corresponds to one of the various authentication algorithms implemented by the eUICC, and (ii) authentication parameters that are compatible with the authentication algorithm.

Abstract: Secure reception of a certificate revocation list (CRL) is determined. In some embodiments, a device initiates a CRL update by sending a message with a timestamp to an embedded universal integrated circuit card (eUICC). The eUICC generates a session identifier, nonce, or random number and builds a payload including an internal time value based on a server time, and an internal time value based on a past message received from the device. The eUICC cryptographically signs over the payload and sends it to the device. The device obtains a CRL from a host server, checks the CRL, and, if the CRL passes the device check, sends it to the eUICC along with a second device timestamp and the nonce. The eUICC then performs checks based on the timestamps, the nonce, the CRL and the internal time values to determine whether the CRL has been securely received.
