Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate configurations are performed for each operator and chip platform, then configuration accuracy for specific operators is improved, but device complexity and management difficulty increase
Solution Approach 1:
The application processor performs unified management of on-card configuration characteristics across all operators and chip platforms through a single management interface. This universal approach allows the same management mechanism to handle diverse configuration scenarios without requiring separate specialized configurations for each operator or platform, thereby reducing management complexity while maintaining configuration accuracy.
Solution Approach 2:
The application processor acts as an intermediary between the modem processor and the upper layers, centralizing the management of on-card configuration characteristics. By introducing this intermediary management layer, the system can standardize configuration management procedures and avoid the complexity of direct, operator-specific configuration paths, thus simplifying overall system management while preserving the need for operator-specific configuration details.
2Adaptability or versatility
If separate code adaptation is performed for each chip platform, then platform-specific compatibility is improved, but development time and cost increase
Solution Approach 1:
The application processor implements a universal configuration management interface that works across multiple chip platforms without requiring platform-specific code adaptations. This unified interface approach allows the same management code to be used for different chip platforms, eliminating the need for separate code adaptation for each platform while maintaining platform compatibility through standardized communication protocols.
Solution Approach 2:
The system segments the configuration management function from the modem processor, placing it in the application processor where it can be independently managed. This segmentation allows the management logic to be separated from platform-specific modem implementations, enabling universal management code that can be applied across different chip platforms without time-consuming platform-specific adaptations.
3Ease of operation
If unified management based on application processor is implemented, then ease of operation is improved, but control precision over modem configurations may be reduced
Solution Approach 1:
The application processor serves as an intermediary that maintains high-level unified management while communicating with the modem processor through standardized interfaces. This intermediary role allows the application processor to provide easy unified management operations while preserving precise control over modem configurations through well-defined communication protocols and configuration parameters, thus reconciling ease of operation with control precision.
Solution Approach 2:
The system transitions from low-level direct modem configuration control to high-level application processor management, adding a dimensional layer of abstraction. This dimensional change enables unified management operations to be performed at the application level while maintaining precise control through standardized interface protocols that translate high-level commands into accurate low-level configuration actions, thus achieving both ease of operation and control precision.

AI summary
Embodiments of this application provide a configuration management method for an on-card configuration characteristic, and an electronic device. In the method, if a configuration state of a terminal on-card characteristic obtained by an application processor in a Modem is inconsistent with an expected state, the application processor indicates the Modem to adjust the configuration state of the terminal on-card characteristic, so that the configuration state is consistent with the expected state.
