Device validation, distress indication, and remediation
First Claim
1. A wireless device comprising a processor, a memory, and communication circuitry, the wireless device configured to connect to a communications network via the communication circuitry, the wireless device including computer-executable instructions stored in the memory of the wireless device which, when executed by the processor of the wireless device, perform operations comprising:
- performing a first integrity check on a component of the wireless device;
determining that the component has failed the first integrity check;
in response to determining that the component has failed the first integrity check, preventing a release of a key used for attachment to the communications network;
determining a functionality that corresponds to the failed component; and
sending, to a network entity, an indication of the functionality that corresponds to the failed component.

Abstract
A wireless communications device may be configured to perform integrity checking and interrogation with a network entity to isolate a portion of a failed component on the wireless network device for remediation. Once an integrity failure is determined on a component of the device, the device may identify a functionality associated with the component and indicate the failed functionality to the network entity. Both the wireless network device and the network entity may identify the failed functionality and/or failed component using a component-to-functionality map. After receiving an indication of an integrity failure at the device, the network entity may determine that one or more additional iterations of integrity checking may be performed at the device to narrow the scope of the integrity failure on the failed component. Once the integrity failure is isolated, the network entity may remediate a portion of the failed component on the wireless communications device.
