Personalization Server for eUICC Profile Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SIM card personalization methods require operators to communicate with different card manufacturers' servers, leading to complexity and inefficiency, especially when dealing with embedded universal integrated circuit cards (eUICCs) that need over-the-air (OTA) personalization.
Innovation Solution
A method and server system that allow operators to interface with a personalization server to generate and send proprietary personalization scripts to eUICCs, using pre-personalization script servers to create customized profiles without modifying existing interfaces, enabling the transformation of generic cards into service-specific cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If operators communicate with different card manufacturers' servers for personalization, then proprietary scripts can be generated for each card type, but the system complexity and communication overhead increase significantly
Solution Approach 1:
The patent introduces a personalization server as an intermediary component that sits between operators and multiple card manufacturers' servers. This personalization server receives personalization requests, selects appropriate pre-personalization scripts from different manufacturers based on card type identification, and generates final personalization scripts. This mediator architecture allows the system to support multiple card types without requiring operators to directly communicate with each manufacturer's server, thus reducing system complexity while maintaining adaptability.
2Adaptability or versatility
If personalization scripts are generated dynamically for each card type, then compatibility across different card manufacturers is improved, but the personalization process time and computational resources increase
Solution Approach 1:
The patent implements pre-personalization scripts that are prepared in advance by card manufacturers for their specific card types. These pre-personalization scripts contain card-type-specific configuration details and are stored on the personalization server before any personalization request occurs. When a personalization request is received, the system quickly identifies the card type and retrieves the corresponding pre-prepared script, rather than generating the entire script from scratch. This preliminary preparation significantly reduces the time required for the personalization process while maintaining full compatibility with different card manufacturers.
3Ease of operation
If a centralized personalization server is introduced to manage multiple card types, then operator interface complexity is reduced, but the server infrastructure and operational requirements increase
Solution Approach 1:
The personalization server is designed with multi-functional capabilities to handle diverse card types from different manufacturers through a single unified interface. It incorporates card type identification functionality, automatic selection of appropriate pre-personalization scripts, and generation of standardized personalization scripts that work across multiple card types. This universal design allows operators to interact with a single server regardless of the card manufacturer or type, simplifying their workflow while the server internally manages the complexity of supporting multiple card formats and manufacturers.

AI summary
Methods and device for personalizing a secure element (e.g., a eUICC) may include or implement operations for receiving a personalization request issued by an operator to download a personalized profile in compliance with a model into the secure element, and the request may include personalization data, an identifier of the secure element and the identifier of the model. Other operations may include using the identifier of the secure element to identify a pre-personalization server suitable for pre-personalizing the secure element; obtaining a message from the pre-personalization server, the message including a pre-personalization script for the secure element based on the description of the model; generating a personalization script for the secure element by using the pre-personalization script and the personalization data; and sending the personalization script to the secure element, the secure element being suitable for executing the personalization script to install the personalized profile in the secure element.
