eUICC Profile Management via Remote Intermediary Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eUICC management systems lack a method for a user to centrally manage multiple devices equipped with secure elements, requiring local profile assistants for each device, which is inefficient and inconvenient.
Innovation Solution
An electronic device and server system that allows users to manage multiple eUICC profiles across various devices through a single interface, enabling flexible use of profiles across multiple devices and remote profile management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manage eUICC profiles locally on each device using local profile assistants, then each device can independently manage its profiles, but users cannot centrally manage multiple devices from a single interface
Solution Approach 1:
The patent introduces a remote device as an intermediary management interface that allows users to centrally manage eUICC profiles across multiple devices. The remote device receives management requests from the user and forwards them to the target devices, eliminating the need for users to access each device individually while maintaining the existing local profile assistant architecture on each device.
Solution Approach 2:
The patent segments the profile management function into two parts: the local profile assistant on each device that handles actual profile operations, and a remote device that provides centralized management interface. This segmentation allows users to manage multiple devices from one location while each device maintains its independent profile management capability.
2Adaptability or versatility
If multiple physical SIM cards are used in electronic devices, then multi-profile communication functions are supported, but device hardware complexity and management difficulty increase
Solution Approach 1:
The patent implements eUICC technology that allows a single secure element to store and manage multiple profiles, replacing the need for multiple physical SIM cards. The eUICC can be remotely provisioned with different profiles through OTA (over-the-air) updates, providing multi-profile communication capability without requiring multiple physical card slots or hardware configurations.
Solution Approach 2:
The patent uses digital copying of profile data to the eUICC through remote provisioning, replacing physical SIM card insertion. Profiles can be downloaded, stored, and activated remotely, eliminating the need for physical hardware changes while maintaining multi-profile functionality.
3Volume of moving object
If eUICC is embedded in electronic devices, then hardware mount area is optimized and device compactness is improved, but physical SIM card replacement and management becomes difficult
Solution Approach 1:
The patent replaces the mechanical system of physical SIM card insertion and removal with an electronic/remote provisioning system. Profiles can be downloaded, installed, and activated remotely through OTA updates, eliminating the need for physical access to the embedded eUICC while maintaining full profile management capability.

AI summary
An electronic device includes a wireless communication circuit, a secure element configured to store information, the information including a first identifier indicating the secure element and at least one second identifier indicating a profile for a wireless communication service provided by at least one cellular network, at least one processor, and a memory configured to store instructions. The instructions, when executed, cause the at least one processor to transmit the first identifier to a first external server, via the wireless communication circuit, receive a second identifier and a profile associated with the second identifier from the second external server via the wireless communication circuit and store the second identifier and the profile in the secure element, and receive a first request, including the second identifier, associated with management of the profile, from the first external server.
