eUICC Profile Transfer via Activation Code and Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mobile communication systems face challenges in efficiently managing and transferring eUICC profiles between terminals, leading to inconvenience for users, especially when switching devices or accessing services from different mobile operators, particularly in scenarios like traveling abroad where physical SIM cards are required.
Innovation Solution
A method and apparatus that enable a terminal to download, install, and manage eUICC profiles through a profile server, allowing for device change support by transmitting capability information and metadata, and using activation codes for profile reinstallation and transfer between terminals, ensuring secure and efficient profile management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If eUICC profiles are managed through physical SIM cards, then device compatibility and network access are ensured, but user convenience deteriorates due to the need for manual card handling during device changes
Solution Approach 1:
The patent replaces the mechanical system of physical SIM card insertion and extraction with an electronic/digital system for remote profile downloading and installation. The terminal device communicates with the profile server to download and install eUICC profiles electronically, eliminating the need for physical card handling and manual intervention during device changes.
2Adaptability or versatility
If eUICC profiles are remotely downloaded and installed, then user convenience is improved by eliminating physical SIM cards, but system complexity increases due to profile server coordination and activation code management
Solution Approach 1:
The patent introduces a profile server as an intermediary component that mediates between the terminal device and the eUICC profile storage system. The profile server handles profile distribution, activation code generation, and installation coordination, thereby managing the complexity of remote profile management centrally rather than distributing it across multiple terminal devices.
3Reliability
If activation codes are used for profile installation, then secure profile deployment is achieved, but service disruption time increases during device changes due to code verification and profile downloading
Solution Approach 1:
The patent implements preliminary action by pre-generating and distributing activation codes to terminal devices before actual profile installation is needed. The activation codes are prepared in advance and stored securely in the terminal, allowing for rapid profile deployment when device changes occur, thereby reducing service disruption time while maintaining security through the pre-validated activation code mechanism.

AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The disclosure relates to a method and an apparatus for installing and managing an eUICC profile. The method comprises: receiving, from a terminal through the transceiver, a message comprising capability information indicating whether a device change function is supported; determining that the terminal supports a device change, based on the capability information indicating that the device change function is supported; and transmitting, to the terminal through the transceiver, metadata comprising a device change configuration based on a determination that the terminal supports the device change.
