Dynamic Network Lock Configuration via SIM Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face difficulties in being configured to connect to different network service providers after a network lock is set up, limiting their flexibility and usability.
Innovation Solution
An electronic device with a communication module and processor identifies a subscriber identification module, generates a signature, and configures a network lock function based on received network lock information from a server, allowing it to switch between network service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a network lock is configured in the electronic device before release, then network security and service provider restriction are improved, but the ability to switch between network service providers deteriorates
Solution Approach 1:
The network lock configuration is made dynamic by allowing it to be set or released based on user input and carrier information. The system can transition between locked and unlocked states, enabling the device to adapt between security and flexibility requirements depending on the operational context.
Solution Approach 2:
The network lock function is pre-configured in the electronic device before release, with the capability to automatically identify carrier information and apply appropriate lock settings. This preliminary configuration ensures security is established upfront while maintaining the option for future modification through user input or carrier detection.
2Ease of operation
If network lock function is automatically configured based on carrier information, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The network lock configuration system performs self-service by automatically detecting carrier information from the inserted SIM card and applying the appropriate network lock settings without requiring manual user configuration. The system identifies the carrier and configures the lock function autonomously, reducing the operational burden on the user.
Solution Approach 2:
The system incorporates feedback mechanisms where the detected carrier information is used to dynamically adjust the network lock configuration. The configuration process receives feedback from the SIM card identification and automatically adapts the lock settings based on the identified carrier, creating a closed-loop control system.

AI summary
An electronic device according to an embodiment of the disclosure may include a communication module, a subscriber identification module, and at least one processor. The at least one processor may identify identification information of the subscriber identification module stored in the subscriber identification module when the subscriber identification module is identified as being first inserted, may configure a network service provider based on the identified identification information, may generate a signature by using lock information of the subscriber identification module, may identify network lock information when the signature is identified as being valid, and may set up a network lock function of the communication module based on the identified network lock information.
