Wireless Device eSIM Provisioning With Flagged-Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless devices flagged for certain activity experience unnecessary interactions and lack of user feedback when attempting to communicate with mobile network operators, leading to wasteful power and network bandwidth consumption.
Innovation Solution
Implement methods involving a provisioning server, local profile assistant, and embedded UICC to manage communication by querying an equipment identity registry for device status, updating configurations, and providing user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the MNO abandons communication with a flagged wireless device, then harmful interactions are eliminated, but unnecessary power and network bandwidth are consumed before abandonment occurs
Solution Approach 1:
The system performs preliminary checking of the wireless device's status against the equipment identity registry before establishing full communication. The provisioning server queries the registry to determine if the device is flagged, and only proceeds with eSIM profile provisioning if the device is not flagged. This preliminary action prevents wasteful power and bandwidth consumption by abandoning communication only when necessary, not prematurely.
2Object-affected harmful factors
If the MNO abandons communication with a flagged wireless device, then unnecessary interactions are eliminated, but the user receives no feedback about why communication is denied
Solution Approach 1:
The system implements feedback by notifying the wireless device when its status is retrieved from the equipment identity registry. The provisioning server sends a notification to the device indicating whether it is flagged or not. This feedback mechanism informs users about the status of their device and the reason why communication may be denied, eliminating the information loss that would otherwise occur.
3Reliability
If the MNO checks device status against the equipment identity registry, then harmful interactions are prevented, but additional communication steps are required
Solution Approach 1:
The system introduces an equipment identity registry as an intermediary component that stores and manages the status of wireless devices. The provisioning server queries this registry to determine whether a device is flagged before proceeding with communication. This intermediary simplifies the overall system architecture by centralizing device status management, making the reliability improvement achievable without proportionally increasing communication complexity.

AI summary
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.
