Secure Element Configuration via Terminal Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure element configuration methods for UICC and eUICC do not always result in the optimal personalization profile for terminal usage, as they rely on remote server configuration modules that send pre-selected profiles without considering the terminal's specific conditions or network capabilities.
Innovation Solution
A notification method that allows the secure element to obtain and send information about its configuration to a configuration system, which then provides tailored configuration data based on the terminal's specific conditions, such as network type and communication channels, optimizing the configuration process.

Engineering Contradiction Analysis
1Ease of operation
If a remote server configuration module sends a pre-selected personalization profile to the secure element, then the configuration process is simplified and automated, but the profile may not be optimal for the terminal's specific network conditions and capabilities
Solution Approach 1:
The secure element sends information about terminal conditions (network type, communication channels) to the configuration system, which uses this feedback to select the most appropriate personalization profile. This feedback loop ensures the profile is optimized for the specific terminal environment while maintaining automated configuration.
Solution Approach 2:
The configuration system pre-prepares multiple personalization profiles tailored to different terminal conditions and network capabilities. When configuring the secure element, the system has already analyzed terminal characteristics and selected the optimal profile in advance, combining preliminary analysis with automated deployment.
2Adaptability or versatility
If the secure element uses a standardized configuration approach, then compatibility across different terminals is improved, but the configuration cannot be optimized for specific network types and terminal capabilities
Solution Approach 1:
The configuration system is designed to handle multiple terminal types, network conditions, and profile requirements through a universal interface. The secure element uses standardized protocols to communicate terminal characteristics, allowing the configuration system to universally apply appropriate profiles across diverse terminals without increasing device complexity.
3Manufacturing precision
If the secure element waits for operator selection of personalization profile, then profile suitability is maximized, but configuration time and user burden increase
Solution Approach 1:
The secure element autonomously provides information about terminal conditions to the configuration system and receives the optimal personalization profile without requiring operator intervention. This self-service approach maintains high profile selection accuracy while significantly reducing configuration time and user burden.

AI summary
Notification devices and methods for configuring a secure element incorporated into a terminal connected to a network are disclosed. The devices and methods may perform steps implemented by an application of the secure element, such as obtaining at least one item of information that can be used to configure the secure element stored in a memory of the terminal outside the secure element, sending the item of information and an identifier of the secure element to a configuration system, and obtaining configuration data originating from the configuration system, the configuration data being supplied to the secure element depending on the item of information.
