eSIM Provisioning via Primary Device Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Secondary mobile wireless devices often lack the capability for effective cellular service management due to limited display and input/output functionality, necessitating assistance from a primary mobile wireless device for tasks like eSIM provisioning, modification, and deletion.
Innovation Solution
A system where a secondary mobile wireless device receives authorization from a primary mobile wireless device to manage eSIMs, involving a push notification server, eSIM discovery server, and MNO provisioning server for eSIM provisioning, with user authorization prompts and a monitoring procedure to ensure successful activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular service management functions are implemented on secondary mobile wireless devices, then device functionality and service access are improved, but device complexity and management difficulty increase due to limited display and input/output capability
Solution Approach 1:
A primary mobile wireless device acts as an intermediary between the user and the secondary mobile wireless device for eSIM management operations. The primary device receives user input, displays information, and transmits management commands to the secondary device, thereby enabling cellular service management on the secondary device without requiring complex display and input interfaces on the secondary device itself.
2Ease of operation
If eSIM provisioning is enabled on secondary mobile wireless devices, then service accessibility is improved, but authorization security requirements increase due to the need for user verification
Solution Approach 1:
The primary mobile wireless device serves as a secure intermediary for authorization. It receives biometric or passcode input from the user, verifies authorization locally, and then transmits authorized commands to the secondary device. This approach maintains security by keeping sensitive verification processes on the primary device while still enabling easy service access on the secondary device.
Solution Approach 2:
Authorization is obtained in advance on the primary device before eSIM provisioning operations are executed on the secondary device. The system performs preliminary security verification and stores authorization tokens, allowing subsequent eSIM management operations to proceed without repeated user verification, thus balancing security with operational ease.
3Productivity
If eSIM provisioning processes are automated on secondary mobile wireless devices, then provisioning speed is improved, but risk of unauthorized provisioning increases
Solution Approach 1:
The primary mobile wireless device acts as a mandatory intermediary that authenticates all provisioning operations before they are executed on the secondary device. Even though the provisioning process itself is automated and fast on the secondary device, every critical operation requires prior authorization verification through the primary device, preventing unauthorized provisioning while maintaining high execution speed.
Solution Approach 2:
The system implements a feedback mechanism where the secondary device sends provisioning status and eSIM information back to the primary device for verification. The primary device then provides feedback authorization commands to confirm or reject the provisioning operation, ensuring that automated processes remain under user control and security requirements are met.
