This Application sets forth techniques for managing communication with wireless devices that have been flagged due to certain activity. In particular, the techniques effectively eliminate unnecessary interactions and enable enhanced user feedback when wireless devices that have been flagged are attempting to interact with mobile network operators (MNOs). The techniques can be implemented by a variety of entities to achieve different and efficient results under various scenarios. Such entities can include, for example, i) equipment identity registries that track unique identifiers of wireless devices that have been flagged due to certain activity, ii) MNO servers, such as SM-DP+ servers, and iii) wireless devices. Additionally, individual components within wireless devices can implement the techniques variously, including using issuer security domain root (ISD-R) components, local profile assistants (LPAs), electronic subscriber identity module (eSIM) components, and/or baseband components included in the wireless devices.

Techniques for managing communication with wireless devices flagged for certain activity

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.

Profile and subscription management for wireless devices

The described embodiments set forth techniques for testing a wireless device configured to use an embedded Universal Integrated Circuit Card (eUICC) and excluding a removable UICC card. A test apparatus processes application protocol data units (APDUs) for conformance with a standardized test specification, where the APDUs are provided by an eSIM command handler client application that interfaces with a baseband processor in communication with the eUICC that includes test profiles with test applets.

Test certification system for eSIM-only wireless devices

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.

Profile transfer with secure intent

This Application sets forth techniques for managing subscriber identity module (SIM) toolkit (STK) scheduling for multiple enabled electronic subscriber identity module (eSIM) profiles on an embedded universal integrated circuit card (eUICC) of a wireless device, including managing multiple STK sessions at a baseband processor external to the eUICC of the wireless device. To forestall STK communication for different eSIMs from interfering with execution of processes associated with the eSIMs, a baseband processor can schedule STK sessions to avoid overlap and reduce opportunities for errors in handling eSIM processes. The baseband processor can prioritize whether to queue commands for a second STK session for a second eSIM until a first STK session for a first eSIM ends or to terminate the first STK session to handle the second STK session.

SIM toolkit scheduling for multiple enabled eSIM profiles

Recovering a user equipment (UE) from limited service due to misconfiguration may include providing a universal subscriber identity module (USIM) identification data or a USIM authentication data to a wireless network. Failure data associated with failing to authenticate or identify the UE to the wireless network may be decoded. The failure data received from the wireless network. The failure data may be processed to determine a cause for the failure. Based on processing the failure data, it may be determined that the USIM identification data or the USIM authentication data is misconfigured. In response to determining that the USIM identification data or the USIM authentication data is misconfigured, a recovery for identifying or authenticating the UE to the wireless network may be automatically performed.

Recovering devices from limited service due to mis-configuration

Examples include designation of a standby node. Some examples may include designation of a new node as a standby node when new transactions logged at a master node during a loss of service between a designated standby node and the master node exceeds a transaction threshold before the duration of the loss of service exceeds a timeout threshold.

Designation of a standby node

This disclosure is directed to heartbeat messages for a high-availability redundant distributed computing environment (e.g., a quorum data storage implementation). Heartbeat messages may be sent from a node to other members of a duster as an indication of hardware state, network connectivity, and possibly application status on the sending node. If a member of a cluster (or quorum) goes silent (e.g., misses heartbeats), other members of the duster (or quorum) may consider that member (or the node that hosts that member) to be non-functional and may initiate a recovery action. Techniques are disclosed for using low-latency non-persistent storage for some heartbeat messages (referred to herein as a 'non-persistent heartbeat messages') to replace a portion of typical persistent (e.g., disk-based) heartbeat messages to reduce overall processing for periodic heartbeat messages. Further, implementations that aggregate multiple heartbeat messages from a node into a fewer number of heartbeat messages are disclosed.
