Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of embedded Subscriber Identity Modules (eUICC) for terminal devices faces challenges in managing profiles for network access authentication across multiple operators, lacking standardized management data, instruction interfaces, and security features, which hinders efficient development and commercialization.
Innovation Solution
A profile configuration method and apparatus for eUICC that defines attribute data and policy rules, including profile identifiers, types, states, and security features, along with interoperable interfaces for managing and securing profiles, enabling secure messaging and remote management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If eUICC is used to provide network access authentication function like removable UICC, then terminal miniaturization and durability are improved, but profile management complexity increases due to lack of standardized management data and interfaces
Solution Approach 1:
The patent applies parameter changes by defining specific data structures and parameters for profile management. It establishes standardized parameters including profile identifiers, attribute data structures, policy rules, and instruction interfaces that transform the unstandardized profile management into a structured system with defined parameters and data formats.
Solution Approach 2:
The patent segments profile management into distinct functional components: profile identifiers for unique identification, attribute data structures for profile characteristics, policy rules for management control, and instruction interfaces for operations. This segmentation creates manageable modules that address the complexity through structured division of management functions.
2Adaptability or versatility
If multiple operator profiles are supported in one eUICC, then network access versatility is improved, but security management difficulty increases due to lack of standardized security features
Solution Approach 1:
The patent defines security parameters and policy rules that control profile installation, activation, and management. It establishes standardized security attributes and instruction interfaces that enable secure multi-profile management through defined parameters rather than ad-hoc security measures.
Solution Approach 2:
The patent introduces standardized instruction interfaces and management protocols as intermediaries between multiple profiles and the eUICC system. These standardized interfaces act as mediators that enable secure interaction and management of multiple operator profiles through unified security mechanisms.
3Productivity
If profile remote installation and management are implemented, then deployment efficiency is improved, but lack of standardized instruction interfaces hinders implementation
Solution Approach 1:
The patent defines standardized instruction interfaces with specific parameters and data formats for profile installation, activation, and management operations. This standardization transforms remote profile management from a complex custom implementation into a standardized process with defined parameters and protocols.
Solution Approach 2:
The patent creates universal instruction interfaces that can handle multiple profile management operations (installation, activation, deactivation, deletion) through standardized commands. This multi-functional interface design enables efficient remote management across different operators and profiles using a unified standardized system.
