eSIM Profile Pre-Download Customization for Secure Provisioning

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing eSIM profiles require multiple communication sequences and server coordination for updates, leading to increased complexity, potential errors, and resource consumption, as well as security vulnerabilities.

Innovation Solution

eSIM profiles are modified at a remote SIM provisioning platform before download, allowing customization through user interfaces and batch processing, with encryption and integrity checks, reducing the need for over-the-air updates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If eSIM profiles are updated using over-the-air (OTA) communications after download, then customization and updates can be performed remotely, but server resources and network traffic increase due to multiple provisioning sequences

Engineering Contradiction:

Improveremote customization capabilityVSAvoidserver resource consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by pre-customizing eSIM profiles with branding information, network selection settings, and functionality configurations before download. This allows all modifications to be made in advance at the provisioning platform, eliminating the need for subsequent OTA update sequences and reducing server resource consumption during actual device operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts the customization and modification operations from the post-download OTA process and moves them to the pre-download provisioning stage. By separating the customization phase from the deployment phase, the system performs modifications when profiles are stored in the repository rather than during active device provisioning, reducing network traffic and server load.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If multiple provisioning sequences are used for eSIM profile download and updates, then customization flexibility is achieved, but security vulnerabilities increase due to multiple communication opportunities

Engineering Contradiction:

Improveprofile customization flexibilityVSAvoidsecurity against man-in-the-middle attacks

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

All customization operations including branding, network selection, and functionality modifications are performed in advance before the eSIM profile is downloaded to the device. This preliminary customization eliminates subsequent provisioning sequences, thereby removing multiple security vulnerability points where man-in-the-middle attacks could occur during OTA updates.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent converts the potential harm of multiple provisioning sequences (security vulnerabilities) into a benefit by consolidating all necessary modifications into a single pre-download provisioning operation. The system benefits from performing all customizations upfront, transforming what would be security risks into a streamlined, secure single-sequence process.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Speed

If eSIM profiles are customized after download via OTA communications, then real-time updates are possible, but desynchronization between network service provider and mobile device may occur

Engineering Contradiction:

Improveupdate speedVSAvoidsynchronization status

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent performs all customization operations including branding information, network selection parameters, and functionality configurations before the eSIM profile is downloaded to the mobile device. This ensures that the profile is fully synchronized with the network service provider's intentions from the moment of download, eliminating desynchronization issues that would arise from subsequent OTA modifications.

Inventive Principle:

Principle #10Preliminary action

4Loss of energy

If eSIM profiles are modified before download, then server resources and network traffic are reduced, but the ability to perform post-download updates is limited

Engineering Contradiction:

Improvenetwork traffic reductionVSAvoidpost-download update capability

Core Design Contradiction:

Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent performs comprehensive customization of eSIM profiles including all branding, network selection, and functionality modifications before download. This preliminary action reduces network traffic and server resources by eliminating the need for subsequent OTA update sequences, while still providing full adaptability through the initial configuration options available in the user interface.

Inventive Principle:

Principle #10Preliminary action

AI summary

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for modifying subscriber identity module (SIM) profiles at a remote SIM provisioning (RSP) platform. One of the methods includes receiving a request to modify at least one eSIM profile. The request can be received through a user-interface configured to receive user-inputs to modify eSIM profiles stored in a repository. The user-inputs can be related to modifying the eSIM profiles prior to the eSIM profiles being downloaded on corresponding mobile devices. The method includes retrieving the at least one eSIM profile from eSIM profiles in a repository. The method includes modifying at least one element of the at least one eSIM profile in accordance with the request to modify the at least one eSIM profile, and storing the modified eSIM profile for download to a mobile device.
