eSIM Profile Segmentation for Secure Secondary Service Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks face challenges in maintaining privacy and security, particularly in managing electronic subscriber identity module (eSIM) profiles, which can lead to vulnerabilities in service plan management and network connectivity.
Innovation Solution
The system intelligently manages eSIM profiles by transferring temporary cell service or secondary service plans between devices, utilizing dynamic QR codes and eUICC technology to ensure secure and efficient service plan utilization based on location and usage limits, thereby enhancing privacy and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If eSIM profiles are managed using traditional methods, then service plan management is straightforward, but privacy and security vulnerabilities arise
Solution Approach 1:
The patent segments eSIM profile management by introducing a parent device that holds master control and multiple child devices that receive segmented service plans. The parent device's eSIM profile is divided into multiple child eSIM profiles, each with limited functionality dependent on the parent. This segmentation enables secure distribution of service plans while maintaining centralized control and reducing security vulnerabilities associated with traditional eSIM management methods.
2Reliability
If multiple eSIM profiles are stored for different locations, then network connectivity is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic eSIM profile selection based on the device's current geographic location. The system automatically activates the appropriate child eSIM profile corresponding to the current location, while keeping other profiles inactive. This dynamic approach ensures continuous network connectivity across different regions without the power penalty of maintaining multiple active profiles simultaneously, as only one profile is active at any given time.
3Reliability
If eSIM profiles are transferred manually, then security is maintained, but time required for connection establishment increases
Solution Approach 1:
The patent implements automated eSIM profile transfer mechanisms where the parent device can automatically provision child eSIM profiles to child devices without manual intervention. The system uses automated authentication, profile generation, and transfer processes that maintain security through cryptographic verification while eliminating the time-consuming manual steps of traditional eSIM provisioning. The automated system handles profile activation, configuration, and validation seamlessly.
4Adaptability or versatility
If secondary service plans are created for each device, then service flexibility is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal parent-child eSIM architecture where a single parent eSIM profile can generate multiple child eSIM profiles that work across different devices and locations. This universal system provides service flexibility by allowing any child device to receive appropriate service plans based on location and usage needs, while the parent device maintains centralized management control. The multi-functional parent-child relationship eliminates the need for separate management systems for each device, reducing overall system complexity.

AI summary
Methods and apparatuses for improving the privacy and security of wireless communications by leveraging electronic subscriber identity module (eSIM) profiles to enable number portability and the ability to transfer a secondary service plan from a first computing device to a second computing device are described. A second eSIM profile associated with a secondary service plan that depends on a primary service plan used by the first computing device may be transferred to the second computing device by displaying a QR code on a display screen of the first computing device or by sending an electronic message from the first computing device to the second computing device. The second eSIM profile may be automatically identified by the first mobile device based on a location of the second mobile device.
