UICC NFC Profile Access Using Dedicated Interface Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices face limitations in managing multiple profiles for Near Field Communication (NFC) access, leading to potential security risks and inefficient resource utilization due to shared interface modules.
Innovation Solution
Implementing a mobile device configuration where each profile in the UICC is assigned a dedicated interface module for NFC access, ensuring exclusive and secure communication through a one-to-one relationship, allowing profiles to be installed, removed, or reassigned as needed, with interface modules being reset to default states for reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple profiles share a common interface module for NFC access, then device complexity is reduced, but security is compromised and resource utilization becomes inefficient
Solution Approach 1:
The patent divides the interface module resource into multiple separate interface modules (first interface module, second interface module, etc.), with each profile assigned to a dedicated interface module. This segmentation eliminates security risks associated with shared access while maintaining manageable system complexity through structured allocation.
2Productivity
If multiple profiles share a common interface module, then device complexity is reduced, but resource utilization efficiency deteriorates due to conflicts and limitations
Solution Approach 1:
By segmenting the interface module into multiple dedicated modules for different profiles, the system enables simultaneous or sequential access without conflicts. Each profile has its own interface module, eliminating resource contention and improving overall productivity and resource utilization efficiency.
3Adaptability or versatility
If a single interface module is used for multiple profiles, then ease of manufacture is improved, but adaptability deteriorates when profiles need to be dynamically installed or removed
Solution Approach 1:
The patent creates multiple independent interface modules that can be individually allocated to profiles. This segmentation enables dynamic installation and removal of profiles with dedicated interface modules, providing high adaptability while maintaining manufacturing simplicity through standardized module designs.
Solution Approach 2:
The system implements dynamic allocation where interface modules can be assigned to different profiles based on operational needs. Profiles can be dynamically installed or removed with their dedicated interface modules, allowing the system to adapt to changing requirements while maintaining a structured configuration.

AI summary
A mobile device (100) is disclosed. The mobile device exchanges data in a wireless manner. The mobile device includes: an application processor (110); a baseband modem (120); a universal integrated circuit card, UICC, (130), operatively connected to the base-band modem (120) via a first interface (131); and a contactless interface (140), operatively connected to the UICC (130) via a second interface (139). The UICC (130) stores multiple profiles (151, 152, 153, 154), each of which can selectively be in an enabled state or a disabled state. The UICC (130) stores multiple interface modules (161, 162, 163), each of which allows access of one of the profiles (151, 152, 153, 154) stored in the UICC (130) to the contactless interface (140) via the second interface.
