In-Vehicle USIM Profile Switching for Regional Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle systems face increased complexity and cost due to regulatory requirements for using local SIM profiles in different countries, making it difficult to manage commercial services and deploy global products efficiently, especially for emergency calls like eCall.
Innovation Solution
An in-vehicle system equipped with multiple USIM profiles, each with a unique ICCID, allows automatic selection and switching of the emergency USIM profile based on location, ensuring compliance with regional regulations while enabling efficient deployment of global services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple USIM profiles are stored in the secure element to comply with different national regulations, then the ability to operate in multiple countries is improved, but the device complexity increases
Solution Approach 1:
The secure element is segmented into multiple independent USIM profiles, each containing subscription data for a specific country or region. This segmentation allows the system to store multiple profiles without creating a single complex unified structure, enabling selective activation of appropriate profiles for different operational contexts while maintaining manageable organization within the secure element.
Solution Approach 2:
The system dynamically selects and switches between different USIM profiles based on the vehicle's current location and regulatory requirements. The selection process is automated and occurs in response to location changes, allowing the system to adapt its configuration dynamically rather than requiring manual intervention or pre-configured complex switching mechanisms.
2Reliability
If automatic location-based switching of USIM profiles is implemented, then compliance with regional regulations is improved, but the complexity of managing commercial services increases
Solution Approach 1:
The system performs self-service by automatically detecting its location and selecting the appropriate USIM profile without requiring manual intervention. The automated switching mechanism handles the complexity of profile management internally, freeing the user from manual configuration tasks while ensuring reliable compliance with regional regulations.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor location changes and regulatory requirements, automatically triggering profile switching when conditions change. This feedback loop ensures continuous compliance without requiring complex manual management, as the system responds autonomously to changing operational conditions.
3Ease of manufacture
If a single dedicated preconfigured USIM profile is used, then the ease of deployment is improved, but the ability to comply with different national regulations deteriorates
Solution Approach 1:
The secure element is designed with multi-functionality by incorporating multiple USIM profiles that can serve different countries and regulatory environments. This universal design allows a single device to comply with various national regulations without requiring separate devices for each market, maintaining ease of deployment while enabling global adaptability.
Solution Approach 2:
The system changes operational parameters by switching between different USIM profiles based on location and regulatory requirements. This parameter change approach allows the same hardware platform to adapt to different markets by modifying its configuration parameters rather than requiring hardware changes, maintaining deployment simplicity while enabling regulatory compliance.
