eSIM Profile Pre-Download Customization to Reduce OTA Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eSIM profiles require multiple communication sequences and server resources for updates, leading to increased complexity, potential errors, and security vulnerabilities due to over-the-air (OTA) customizations.
Innovation Solution
eSIM profiles are modified at a remote SIM provisioning (RSP) platform before download, allowing user interfaces for editing and encryption, reducing the need for OTA updates and enhancing security and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If eSIM profiles are modified using over-the-air (OTA) communications after download, then customization can be achieved, but server resources increase, network traffic increases, and security vulnerabilities arise
Solution Approach 1:
The patent applies preliminary action by enabling customization of eSIM profiles before they are downloaded to mobile devices. The RSP platform allows modification of profile elements such as branding information, network selection parameters, and other configuration data during the profile creation stage, rather than requiring post-download OTA updates. This approach consolidates all customization activities into a single pre-download provisioning event, eliminating the need for subsequent modification transmissions and reducing overall network traffic and server resource consumption.
2Adaptability or versatility
If OTA customization is performed, then eSIM profiles can be updated, but multiple provisioning sessions are required increasing complexity and security risks
Solution Approach 1:
The patent eliminates the need for multiple provisioning sessions by performing all customizations in advance during profile creation on the RSP platform. All modifications to branding, network settings, and other profile elements are completed before the profile is downloaded to the mobile device in a single provisioning event. This consolidates what would otherwise require multiple separate OTA update sessions into one streamlined process, significantly reducing procedural complexity.
3Adaptability or versatility
If OTA customization is performed, then profile modifications can be made, but security vulnerabilities such as man-in-the-middle attacks increase
Solution Approach 1:
The patent enhances security by completing all profile modifications before download in a controlled environment on the RSP platform. Since customizations are performed in advance rather than during transmission, the profile data is not exposed to potential man-in-the-middle attacks or other transmission-based security threats. The single pre-download provisioning session eliminates the multiple communication windows that would otherwise exist, thereby removing opportunities for interceptors to compromise profile integrity.
4Adaptability or versatility
If eSIM profiles are customized after download, then updates can be applied, but desynchronization between network provider and mobile device may occur
Solution Approach 1:
The patent ensures profile synchronization by establishing the definitive version of the eSIM profile during the initial pre-download customization process on the RSP platform. Since all modifications are completed before download and the profile is provisioned only once, there is no subsequent divergence between the network provider's records and the mobile device's installed profile. This single-event provisioning model eliminates the desynchronization issues that can arise from multiple update cycles.
Data Source
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.
