eSIM Transfer via OEM Discovery Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for transferring embedded subscriber identity modules (e-sims) from one device to another are cumbersome, require network operator intervention, and are not user-friendly, especially when devices are of different OEMs or when the source device is unavailable.
Innovation Solution
A system and method that allow for the transfer of e-sims from a source device to a target device by determining the priority of the target device relative to the source device, triggering transactions for generating a new profile for the e-sim at the target device, and deleting the e-sim from the source device, all without requiring the source device to be in proximity or available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing e-sim transfer mechanisms are used, then network operator intervention is required, but the process becomes cumbersome and not user-friendly
Solution Approach 1:
The system enables automatic e-sim transfer between devices without requiring network operator intervention. The target device initiates the transfer process by detecting the source device and automatically triggering the e-sim profile download and activation, making the system self-serving and user-friendly
Solution Approach 2:
The patent introduces a discovery server as an intermediary component that facilitates communication between the source and target devices. This server mediates the e-sim transfer process by managing the interaction between devices, enabling automatic profile transfer without direct network operator involvement
2Reliability
If source device must be available and in proximity for e-sim transfer, then transfer reliability is improved, but user convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by having the target device detect and identify the source device before the actual e-sim transfer begins. The target device proactively initiates the transfer process by triggering the discovery server to download the e-sim profile, eliminating the need for the source device to be actively involved or available during the transfer
Solution Approach 2:
The patent replaces the traditional mechanical requirement of physical proximity and active participation between devices with a remote detection and automatic triggering mechanism. The target device can detect the source device and initiate transfer remotely, substituting the need for physical presence with automated system interaction
3Reliability
If e-sim transfer requires network operator intervention, then control and security are maintained, but processing time and complexity increase
Solution Approach 1:
The patent extracts the network operator's manual intervention from the e-sim transfer process. The system automatically handles profile download, activation, and device coordination by having the target device trigger the discovery server to retrieve and install the e-sim profile, eliminating time-consuming manual operations while maintaining security through automated authentication
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a target device is provided. The method comprises detecting a request to transfer an e-sim from a source device to the target device, wherein the source device and the target device are associated with a common OEM entity; and receiving from a MNO entity, a new profile for the e-sim for download and activation at the target device, thereby completing the transfer of the e-sim, wherein a determination that the target device is prior to the source device is performed by the common OEM entity, and wherein a first transaction indicative of a request to generate the new profile for the e-sim for the target device and deletion of the e-sim from the source device is triggered by the common OEM entity upon the determination.
