eSIM Profile Procurement via Multi-Platform RSP Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile network operators (MNOs) face challenges in ensuring continuous eSIM profile provisioning to user devices due to RSP platform failures, errors in eSIM profile batches, and insufficient availability of specific eSIM profiles, leading to provisioning errors and downtime.
Innovation Solution
An eSIM management platform that switches between multiple remote SIM provisioning (RSP) platforms to provision eSIM profiles, manages errors, and rebalances provisioning loads, enabling intelligent SIM profile procurement by routing requests to alternative platforms when thresholds are reached or errors detected, and providing machine-readable codes for profile acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single RSP platform is used for eSIM profile provisioning, then the system is simple to manage, but the system experiences downtime and provisioning errors when the platform fails or encounters errors
Solution Approach 1:
The patent combines multiple RSP platforms into a unified provisioning system where a profile management system coordinates between multiple RSP platforms. This merging approach ensures that if one platform fails, the system can switch to another platform, maintaining provisioning availability while managing complexity through centralized coordination.
Solution Approach 2:
The system dynamically changes the operational parameters of RSP platforms by monitoring error rates, response times, and availability metrics. Based on these parameter changes, the system automatically switches between platforms or adjusts provisioning strategies, maintaining reliability without requiring complex manual intervention.
2Reliability
If multiple RSP platforms are deployed to ensure continuous provisioning, then service availability improves, but system complexity and management difficulty increase
Solution Approach 1:
The profile management system implements self-service capabilities by automatically monitoring RSP platform performance, detecting failures, and switching between platforms without human intervention. This automation maintains provisioning continuity while simplifying operations, as the system manages itself rather than requiring manual platform coordination.
Solution Approach 2:
The system continuously monitors feedback from multiple RSP platforms including error rates, response times, and availability metrics. Based on this feedback, the profile management system dynamically adjusts platform selection and provisioning strategies, maintaining service availability while simplifying management through data-driven automated decisions.
3Productivity
If eSIM profile batches are processed without validation, then provisioning speed increases, but errors in profile batches cause failures
Solution Approach 1:
The system performs preliminary validation and verification of eSIM profile batches before they are deployed to devices. This includes checking profile integrity, validating carrier information, and ensuring compliance with specifications. This preliminary action prevents erroneous profiles from causing provisioning failures while maintaining high throughput through efficient automated validation.
Solution Approach 2:
The system implements selective validation that skips already-verified profiles and focuses validation efforts on new or changed profiles. This approach maintains high provisioning speeds by not re-validating every profile while still ensuring reliability through targeted validation of critical elements and error-prone batches.

AI summary
A mobile network operator (MNO) may receive a request to provide an embedded Subscriber Identity Module (eSIM) profile to an embedded Universal Integrated Circuit Card (eUICC) of a user device. The user device is configured to receive telecommunication services from the MNO. Thus, if it is determined that a particular remote SIM provisioning (RSP) platform of a plurality of RSP platforms is able to provide the eSIM profile, the particular RSP platform is directed to provision the eUICC of the user device with the eSIM profile. However, if a condition that affects an ability of the particular RSP platform to provide the eSIM profile is detected, an alternative RSP platform may be directed to provide the eUICC of the user device with the eSIM profile.
