eUICC Controller Profile Transfer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network technologies face challenges in seamlessly transferring subscriber profiles between User Equipment (UE) devices, particularly with embedded Universal Integrated Circuit Cards (eUICCs), which limits user flexibility in switching between devices without physical SIM card modifications.
Innovation Solution
The implementation of an eUICC controller that enables direct access and management of eUICCs across different UEs, allowing for profile synchronization, disabling, and downloading, thereby facilitating the transfer of wireless network services and profiles between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical SIM card is removed from first UE and inserted into second UE, then wireless network service can be transferred between devices, but physical modifications and manual intervention are required
Solution Approach 1:
The patent replaces the mechanical system of physical SIM card removal and insertion with an electronic/digital system. The eUICC controller enables profile transfer through electronic commands and data transmission over communication interfaces, eliminating the need for physical card manipulation while achieving the same service transfer functionality.
Solution Approach 2:
The eUICC controller acts as an intermediary component that mediates the profile transfer process between UEs. It manages the eUICC devices, authenticates them, and facilitates the secure transfer of subscriber profiles electronically, replacing the direct physical card transfer mechanism.
2Adaptability or versatility
If eUICC profile transfer is implemented without physical SIM card, then device flexibility is improved, but system complexity increases due to eUICC controller requirements
Solution Approach 1:
The eUICC controller is designed as a universal platform that can manage multiple eUICC devices across different UE types. It provides multi-functional capabilities including profile download, transfer, authentication, and management operations, reducing the need for device-specific implementation complexity.
Solution Approach 2:
The system implements self-service mechanisms where the eUICC controller automatically authenticates devices, manages profile transfers, and handles activation procedures without requiring complex manual intervention. The automated authentication and profile management reduce operational complexity despite the enhanced functionality.
3Extent of automation
If automated profile synchronization is implemented, then user interaction is minimized, but processing time and system resources increase
Solution Approach 1:
The system performs preliminary actions by pre-authenticating devices and preparing profile data before the actual transfer is initiated. The eUICC controller maintains ready-to-transfer profile information and authentication credentials, reducing the time required during the actual profile synchronization process.
Solution Approach 2:
The profile transfer process is designed to maintain continuity of useful action through efficient data transmission and processing. The system keeps communication channels open and processes profile data in a continuous manner rather than through multiple discrete steps, reducing overall synchronization time while maintaining automation.

AI summary
An embedded Universal Integrated Circuit Card (“eUICC”) controller may transfer wireless network service between different User Equipment (“UE”) by moving or exchanging one or more profiles between the eUICC of different UEs. The eUICC controller may directly access the eUICC of the UEs in order to control eUICC profile synchronization, disabling, downloading, and/or perform other eUICC management.
