Remote eUICC Profile Management With Owner Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems face challenges in efficiently managing profiles, such as SIM cards, which require physical acquisition and can be costly and inconvenient for users, especially when switching between different mobile operators.
Innovation Solution
A method and apparatus for a user equipment (UE) to control profiles, including receiving remote profile management commands, verifying owner information, and selectively executing commands based on verification to enable, disable, or reject profile management requests, using OTA technology for eUICC cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical SIM cards are used for profile management, then profile security and authenticity are maintained, but user convenience and switching speed deteriorate due to physical acquisition requirements
Solution Approach 1:
The patent creates a digital copy of the SIM profile in the form of profile data that can be remotely downloaded and installed on the eUICC. This digital profile copy enables OTA provisioning, allowing users to switch profiles without physical SIM card handling while maintaining security through cryptographic verification of the profile data integrity
Solution Approach 2:
The patent replaces the mechanical physical SIM card insertion/removal system with an electronic OTA provisioning system. The profile management transitions from physical mechanical operations to wireless electronic downloads and remote code execution, eliminating the need for physical contact while maintaining secure profile installation through encrypted channels and authentication protocols
2Adaptability or versatility
If multiple profiles are stored in eUICC, then profile versatility improves, but verification complexity increases due to owner information checking requirements
Solution Approach 1:
The patent performs preliminary verification of the enabled profile's owner information against the target profile's owner information before executing the remote management command. This advance checking prevents unauthorized operations and ensures profile integrity, allowing the system to handle multiple profiles efficiently with automated verification logic that reduces manual intervention complexity
Solution Approach 2:
The patent implements dynamic profile management where the eUICC can selectively enable, disable, or switch between multiple profiles based on remote commands and verification results. The system adapts its behavior by checking owner information relationships in real-time, allowing flexible profile switching while maintaining security through conditional execution based on verification outcomes

AI summary
A method, performed by a user equipment (UE), of controlling a profile is provided. The method includes receiving a remote profile management command regarding a target profile from a profile server, determining whether an enabled profile exists, verifying whether profile owner information of the target profile corresponds to profile owner information or sub-owner information of the enabled profile, based a result of the determination, and selectively executing the remote profile management command based on a result of the verification.
