eUICC Configuration Using Auxiliary Profiles for Continuous Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for handling secure elements in user devices, such as eUICCs, fail to ensure continuous availability and data integrity during installation processes, leading to potential communication disruptions and security vulnerabilities.
Innovation Solution
A configuration method involving an installation data set and an auxiliary profile data set is used to manage secure elements, ensuring secure and reliable installation processes by storing login credentials in a dedicated storage area and using authentication algorithms, while maintaining continuous availability and data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an installation process updates data on the secure element, then the secure element can maintain security requirements, but communication availability is interrupted during installation
Solution Approach 1:
The patent segments the profile data into two distinct parts: an installation profile data set for security-critical operations and an auxiliary profile data set for communication operations. This segmentation allows the secure element to maintain security during installation while preserving communication availability through the auxiliary profile, resolving the contradiction between security reliability and communication productivity.
2Reliability
If login credentials are stored in a dedicated storage area, then data integrity is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by creating a dedicated storage area specifically for installation profile credentials, distinct from other profile data. This localized storage approach improves data integrity for critical installation operations while keeping the overall device structure manageable through clear separation of concerns, rather than uniformly complicating the entire storage system.
Data Source
AI summary
A method and system for configuring a user device for participation in a telecommunications network are disclosed, with a secure element, such as an eUICC, which is configured to administrate at least one profile dataset for secure operation of the user device. An installation dataset is provided for accompanying at least part of an installation process for installing data on the secure element. An auxiliary profile data set is provided to enable access to a telecommunications network.
