e-SIM Profile Transfer via Server Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for transferring e-SIM profiles across devices are complex and inefficient, requiring users to interact multiple times with Mobile Network Operators (MNOs) and deploying significant resources, leading to a poor user experience.
Innovation Solution
A method and system for transferring an e-SIM profile from a first communication device to a second, involving a server that receives a transfer request message with e-SIM identifiers, performs mapping, and transmits the e-SIM profile to the second device, allowing user-controlled and efficient profile transfer without direct MNO interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional e-SIM profile transfer methods are used, then the transfer can be completed, but the process requires multiple user interactions with MNOs and deploys significant resources, making it complex and inefficient
Solution Approach 1:
The patent extracts the MNO interaction step from the e-SIM profile transfer process. Users can now transfer profiles directly between devices using device-to-device communication without needing to contact MNOs, thereby simplifying the process while maintaining transfer functionality
Solution Approach 2:
The system enables self-service e-SIM profile transfer where users independently complete the transfer process between devices without requiring MNO intervention. The devices autonomously handle the profile extraction and installation, reducing both complexity and resource deployment
2Ease of operation
If conventional e-SIM profile transfer methods are used, then the transfer can be completed, but it requires multiple user visits to MNO locations, leading to poor user experience
Solution Approach 1:
The patent replaces the mechanical/physical system of visiting MNO locations with a digital communication system. Profile transfer occurs through electronic data exchange between devices, eliminating the need for physical travel and face-to-face interactions
Solution Approach 2:
The system performs preliminary authentication and authorization checks between devices before initiating the transfer. This preliminary action ensures security while enabling immediate transfer without requiring subsequent MNO visits for verification

AI summary
A method for transferring an embedded Subscriber Identity Module (e-SIM) profile from a first communication device to a second communication device. The method includes: receiving, at a server from the first communication device, an e-SIM transfer request message including an e-SIM identifier (EID) corresponding to each of the first communication device and the second communication device. The received e-SIM transfer request message corresponds to a request for transferring the e-SIM profile from the first communication device to the second communication device. The method also includes: performing a mapping process to map the e-SIM profile associated with the EID of the first communication device with the EID of the second communication device based on the received e-SIM transfer request message; and transmitting, to the second communication device, the e-SIM profile that is mapped with the EID of the second communication device.
