IMS Configuration Update via Store Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for updating IP multimedia subsystem (IMS) configuration information, such as FOTA and OMC, are inefficient due to large update data sizes and time-consuming processes, and may not function correctly when a universal subscriber identity module (USIM) from a different mobile network operator is inserted into an electronic device.
Innovation Solution
An electronic device and its operating method that updates IMS configuration information by receiving update data through a store application, updating the IMS configuration kit application, and renewing the IMS configuration information based on the received resources, allowing for efficient and correct updates even with customer-specific customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If FOTA method is used to update IMS configuration information, then the update can be performed over the air, but the update data size becomes large and download time increases
Solution Approach 1:
The patent extracts only the essential IMS configuration data from the full FOTA update package, separating critical configuration information from optional application components. This allows the device to download and apply minimal necessary data for IMS functionality without requiring the complete application bundle, significantly reducing download time while maintaining over-the-air update capability.
Solution Approach 2:
The update process is segmented into multiple phases: first downloading compact configuration data, then selectively updating only the IMS-related components rather than the entire application suite. This segmentation allows the critical IMS configuration to be updated quickly while deferring or skipping non-essential application updates, reducing overall update time.
2Ease of operation
If FOTA method is used to update IMS configuration information, then remote updating is enabled, but the number of applications to be optimized increases and processing time increases
Solution Approach 1:
The patent extracts and identifies only the specific IMS configuration components that require updating from the comprehensive FOTA package. By filtering out unnecessary application files and focusing solely on essential IMS configuration data, the system minimizes the number of files that need to be processed, optimized, and installed, thereby improving update processing efficiency while maintaining remote update capability.
Solution Approach 2:
The system performs partial updating by applying only the necessary IMS configuration changes without fully processing or optimizing all application components in the FOTA package. This selective approach updates only what is strictly required for IMS functionality, reducing the overall processing burden and improving efficiency.
3Ease of operation
If FOTA method is used to update IMS configuration information, then over-the-air deployment is achieved, but reboot time increases
Solution Approach 1:
The patent implements preliminary configuration of the IMS update process by pre-packaging configuration data in a format that requires minimal processing during actual update execution. The configuration files are pre-validated and structured to enable rapid application without requiring extensive system reinitialization or prolonged reboot periods, thus reducing downtime while maintaining over-the-air deployment capability.
4Manufacturing precision
If OMC update method is used for customer-specific customization, then targeted updates are possible, but updates fail when USIM from different mobile network operator is inserted
Solution Approach 1:
The patent creates a universal IMS configuration update mechanism that can handle multiple mobile network operator configurations through a single standardized interface. The system detects the inserted USIM card's operator and automatically selects or generates appropriate configuration data from a universal template structure, enabling the same update process to work correctly across different operators while maintaining customer-specific customization capabilities.
Solution Approach 2:
The system uses parameter-based configuration where the core update structure remains constant but specific parameters (such as operator identifiers, network codes, and service parameters) are dynamically changed based on the detected USIM card. This allows the OMC update method to maintain its precision for customer-specific customization while adapting to different mobile network operators through parameter substitution rather than requiring operator-specific update processes.
Data Source
AI summary
An electronic device according to an embodiment may include a communication circuit, a processor, operatively connected to the communication circuit, and a memory operatively connected to the processor. The memory may store instructions to cause the processor to update an application including IP multimedia subsystem (IMS)-related data. Based on the update data received from a server through the communication circuit, obtain the updated IMS-related data through the application when the application is updated, and renew the IMS configuration information.
