SIM Setting Database for Automatic Service Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of dual or multi-SIM electronic devices often face manual selection challenges when adding new SIMs, leading to potential wrong SIM selection for services and loss of SIM setting information when transferring eSIMs between devices.
Innovation Solution
An electronic device with a processor configured to identify SIM-related information in a database and automatically select the appropriate SIM for services based on SIM setting information, including synchronization with external databases for updated settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual SIM selection is implemented for service assignment, then user control over SIM selection is improved, but user error in selecting wrong SIM and loss of SIM setting information occurs
Solution Approach 1:
The system automatically detects SIM insertion events and retrieves corresponding SIM setting information from the database without requiring user intervention. The processor automatically assigns the correct SIM to services based on the retrieved setting information, enabling the system to serve itself and eliminate user errors.
Solution Approach 2:
The system establishes a feedback mechanism where SIM insertion events trigger automatic detection and retrieval of SIM setting information from the database. This closed-loop feedback ensures that the correct SIM is consistently assigned to services based on stored configuration data, preventing selection errors.
2Extent of automation
If SIM setting information is stored in a database, then automatic SIM selection is improved, but synchronization complexity when eSIM is transferred increases
Solution Approach 1:
SIM setting information is pre-stored in the database before SIM transfer occurs. When a SIM is inserted, the system automatically retrieves the pre-stored setting information from the database, eliminating the need for complex real-time synchronization during transfer and simplifying the overall mechanism.
Solution Approach 2:
The system uses a database to store copies of SIM setting information that can be retrieved and applied when SIMs are inserted or transferred. This copying mechanism allows automatic restoration of SIM assignments across different devices without requiring complex synchronization protocols.
3Adaptability or versatility
If eSIM is transferred to another electronic device, then device flexibility is improved, but SIM setting information restoration fails without synchronization
Solution Approach 1:
The database stores SIM setting information in a universal format that can be retrieved and applied across different electronic devices. This multi-functional approach allows the same database structure to serve multiple devices and SIM transfer scenarios, ensuring setting information restoration works universally.
Solution Approach 2:
SIM setting information is pre-stored in the database before transfer occurs, enabling automatic restoration when the eSIM is inserted into another device. This preliminary storage action ensures that setting information is available for immediate retrieval without requiring complex synchronization during the transfer process.
Data Source
AI summary
An electronic device is provided. The electronic device includes a memory and at least one processor operatively connected to the memory, and the at least one processor is configured to, based on a subscriber identity module (SIM) change event, in which at least one SIM is inserted, occurring, identify whether SIM-related information related to the at least one SIM exists in a database which is stored in the memory and includes SIM setting information for services provided by the electronic device, and in case of being identified that the SIM-related information exists in the database, select a SIM for each of the services based on the SIM setting information.
