Secure Element Service Provider Display for Dual SIM Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems lack an effective method to collectively display and manage communication service provider information across various secure elements, such as UICC, eUICC, and iSSP, and to support dual SIM functions while adhering to policy rules and state information of each secure element.
Innovation Solution
A method and apparatus that processes communication service provider information by identifying the type of secure elements in a terminal, executing appropriate applications, and collectively displaying a list of service providers, while enabling or disabling them based on policy rules and state information, and supporting dual SIM functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple secure elements (UICC, eUICC, iSSP) are supported in a terminal, then the versatility and service capability are improved, but the device complexity and management difficulty increase
Solution Approach 1:
The patent segments the management of communication service provider information by creating separate applications for each secure element type (UICC application, eUICC application, iSSP application). Each application handles its specific secure element independently, while a unified interface collects and displays information from all sources. This segmentation resolves the contradiction by maintaining versatility through multi-element support while reducing management complexity through specialized, isolated handling of each element type.
Solution Approach 2:
The patent introduces a unified interface as an intermediary layer between the multiple secure elements and the user. This interface collects communication service provider information from various secure elements (UICC, eUICC, iSSP) through their respective applications and presents a consolidated list to the user. The intermediary absorbs the complexity of managing multiple secure elements while providing a simplified view to the user, thus resolving the contradiction between versatility and management difficulty.
2Adaptability or versatility
If dual SIM function is supported across different secure element types, then the adaptability is improved, but the difficulty of detecting and measuring system state increases
Solution Approach 1:
The patent creates a unified interface that serves multiple secure element types (UICC, eUICC, iSSP) through a single communication service provider selection function. This universal interface handles dual SIM functionality across different secure element combinations without requiring separate management mechanisms for each combination. The multi-functional design resolves the contradiction by supporting diverse dual SIM configurations while maintaining a consistent, manageable system state through a single interface.
Solution Approach 2:
The patent implements feedback mechanisms within each secure element-specific application (UICC, eUICC, iSSP) to report their state information to the unified interface. The unified interface collects this feedback from all secure elements and uses it to determine which communication service providers are available for selection. This feedback system resolves the contradiction by automatically tracking the complex system state across multiple secure elements, making dual SIM functionality adaptable while keeping state monitoring manageable through automated information collection.
3Ease of operation
If communication service provider information is collectively displayed from multiple secure elements, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent merges the communication service provider information from multiple secure elements (UICC, eUICC, iSSP) into a single consolidated list displayed through the unified interface. Instead of requiring users to separately access and manage information from each secure element, the system combines all available service providers into one view. This merging resolves the contradiction by improving ease of operation through unified display while managing the increased system architecture complexity through modular, type-specific applications that feed into the consolidation process.
