Certificate Application Interface Adaptation for Multi-Entity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The need for multiple interfaces within terminal devices to interact with different certificate management function entities increases development costs and reduces idle storage space, prolonging the development period in communications systems.
Innovation Solution
Implementing an interface adaptation function entity that interacts with certificate management entities on behalf of the terminal device, reducing the need for local interfaces and allowing interaction with multiple certificate management entities through a unified interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple interfaces are set inside the terminal device to interact with different certificate management function entities, then the terminal device can ensure compatibility with various institutions, but this increases development costs, reduces idle storage space, and prolongs development period
Solution Approach 1:
An interface adaptation function entity is introduced as an intermediary between the terminal device and multiple certificate management function entities. This mediator handles all interface adaptations and interactions, allowing the terminal device to communicate with diverse certificate management entities through a unified interface, thereby reducing the number of interfaces required in the terminal device while maintaining compatibility
Solution Approach 2:
The interface adaptation function entity provides universal functionality by supporting multiple certificate management function entities through a single interface. This multi-functional entity can adapt to different interface standards and protocols, enabling one interface to serve multiple purposes and multiple entities, thus reducing the overall complexity in the terminal device
2Adaptability or versatility
If multiple interfaces are set inside the terminal device, then different certificate management function entities can be interacted with, but this reduces idle storage space of the terminal device
Solution Approach 1:
By introducing the interface adaptation function entity as a mediator, the terminal device does not need to store multiple interface implementations locally. The adaptation logic is moved to the intermediary, freeing up storage space in the terminal device while maintaining the ability to interact with different certificate management entities
3Adaptability or versatility
If multiple interfaces are set inside the terminal device, then compatibility with various certificate management entities is ensured, but this increases development costs and prolongs development period
Solution Approach 1:
The interface adaptation function entity serves as a pre-developed intermediary that handles all interface variations and adaptations. This allows the terminal device to be developed more quickly without needing to implement and test multiple interface configurations, as the adaptation logic is already encapsulated in the intermediary component
Solution Approach 2:
The interface adaptation functionality is prepared in advance as a separate, reusable component. This preliminary preparation of adaptation logic allows terminal devices to be developed more efficiently, as they can leverage the pre-built adaptation capabilities rather than developing interface handling code from scratch for each certificate management entity

AI summary
An example terminal device includes at least one processor and at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to send a certificate application parameter to an interface adaptation function entity; and receive a certificate from the interface adaptation function entity, wherein the certificate is configured by a target certificate management function entity for the terminal device.
