SM-SR to SM-DP eSIM Profile Deletion Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional SM-SR and SM-DP systems lack a notification mechanism for eSIM profile deletions initiated by MNOs, leading to incorrect profile states and erroneous operations, and inefficient resource usage due to indirect methods for tracking profile deletions.
Innovation Solution
Implementing a notification mechanism, such as SMS, for SM-SR to notify SM-DP of eSIM profile deletions initiated by MNOs via ES4.DeleteProfile API calls, ensuring accurate profile state updates and preventing erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional SM-SR and SM-DP systems operate without a notification mechanism for eSIM profile deletions, then the system structure remains simple, but incorrect profile states and erroneous operations occur leading to reduced reliability
Solution Approach 1:
The patent implements a feedback mechanism where the SM-SR sends a notification message to the SM-DP when an eSIM profile deletion is initiated by an MNO. This feedback loop ensures the SM-DP is aware of the deletion and can update the profile state accordingly, preventing erroneous operations and ensuring accurate profile state management throughout the system.
Solution Approach 2:
The notification message acts as an intermediary communication channel between the SM-SR and SM-DP. This intermediary mechanism facilitates the transfer of deletion information from the routing function to the data preparation function, enabling coordinated state management without requiring direct complex integration between the systems.
2Productivity
If indirect methods like periodic audits and queries are used to track profile deletions, then system complexity remains low, but computing resources are wasted and productivity decreases
Solution Approach 1:
The notification mechanism enables continuous and immediate communication of deletion events from SM-SR to SM-DP. Instead of relying on periodic audits or queries, the system maintains continuous awareness of profile states through real-time notifications, eliminating wasted computing resources and improving overall productivity.
Solution Approach 2:
The SM-SR automatically generates and sends deletion notifications to the SM-DP without requiring external audit mechanisms. This self-service approach allows the system to track profile deletions efficiently through automated notification rather than resource-intensive periodic checking, conserving computing resources while maintaining accuracy.

AI summary
A request from a mobile operator network (MNO) is received at a Subscription Manager Secure Routing (SM-SR) associated with the MNO. The request is for deleting an embedded Subscriber Identity Module (eSIM) profile from an embedded Universal Integrated Circuit Card (eUICC) of a machine-to-machine (M2M) device. The eSIM profile is provided by a Subscription Manager Data Preparation (SM-DP) of a third-party partner of the MNO. A command is sent from the SM-SR to an application on the M2M device to delete the eSIM profile from the eUICC of the M2M device. An indication is then received from the application by the SM-SR indicating that the eSIM profile has been deleted. Accordingly, the SM-SR associated with the MNO may send a notification to the SM-DP of the third-party partner indicating that the eSIM profile has been deleted from the eUICC of the M2M device.
