Mobile Profile Sharing Across Integrated Circuit Cards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for sharing a profile across different integrated circuit cards, such as those used in mobile devices, are cumbersome and require user intervention, especially when switching between devices or in cases of device failure.
Innovation Solution
A method and system that enables a given profile to be shared across multiple mobile devices by performing a procedure that allows the profile to be enabled on a new device, involving network attach procedures, identifier information exchange, and authentication processes to update location and disable the profile on the previous device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a profile is stored on a single integrated circuit card for mobile device operation, then security and reliability are improved, but device versatility and ease of switching between devices deteriorate
Solution Approach 1:
The profile is segmented into multiple instances stored on different integrated circuit cards. Each card contains a portion or copy of the profile data, allowing the profile to be distributed across multiple physical carriers. This enables the user to switch between devices by using different cards while maintaining security through distributed storage.
Solution Approach 2:
The integrated circuit card system is designed to be universal, where a single profile can be enabled on multiple cards that can operate across different mobile devices. The card and profile system becomes multi-functional, supporting both security requirements and device versatility by allowing the same profile to function on various cards and devices.
2Ease of operation
If manual intervention is required for profile switching between devices, then security control is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service functionality where the profile switching process is automated. When a user inserts a different integrated circuit card into the mobile device, the system automatically detects the card, retrieves the appropriate profile information, and enables it without requiring manual intervention. The device and card work together to autonomously complete the switching procedure.
Solution Approach 2:
Profile information is pre-configured and stored on multiple integrated circuit cards before switching is needed. The necessary authentication data and profile configurations are prepared in advance on each card, so when switching occurs, the device can immediately activate the new profile without requiring complex real-time processing or user input.
3Reliability
If network attach procedures and authentication processes are performed for profile sharing, then security is improved, but operation time and complexity increase
Solution Approach 1:
Authentication credentials and security data are prepared and stored in advance on the integrated circuit cards during profile configuration. The cards contain pre-configured authentication information that can be quickly presented to the network during switching, eliminating the need for time-consuming authentication setup during the actual profile switch.
Solution Approach 2:
The authentication profile and security credentials are copied across multiple integrated circuit cards in advance. Each card contains an identical or equivalent copy of the authentication data, so when switching occurs, the network can authenticate the new card immediately using the pre-copied credentials without requiring lengthy verification processes.
