eUICC Profile Reinstallation for Seamless Operator Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UICC cards, such as SIM cards, require physical replacement when switching mobile communication operators, causing inconvenience and high costs for users, especially when traveling or using different networks.
Innovation Solution
The implementation of an embedded UICC (eUICC) that allows remote downloading and management of profiles via OTA technology, enabling seamless switching and installation of SIM modules across terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical SIM card replacement is used for switching mobile communication operators, then network switching is achieved, but user convenience deteriorates and costs increase
Solution Approach 1:
The patent uses virtual copying of the SIM card functionality through eUICC (embedded Universal Integrated Circuit Card) that stores multiple operator profiles. Instead of physically replacing SIM cards, the system creates and switches between virtual copies of operator profiles stored in the eUICC, enabling seamless operator switching without physical card handling.
Solution Approach 2:
The patent replaces the mechanical physical SIM card insertion/removal process with a digital/software-based profile management system. The eUICC stores operator profiles as digital data, and network switching is achieved through software-controlled profile selection and activation, eliminating the need for physical mechanical operations.
2Productivity
If physical SIM card replacement is used for switching mobile communication operators, then network switching is achieved, but time consumption increases
Solution Approach 1:
The patent implements preliminary action by pre-downloading and storing multiple operator profiles in the eUICC before the user needs to switch operators. The system maintains a library of available operator profiles and can instantly activate a different operator's profile without waiting for physical card replacement, significantly reducing switching time.
Solution Approach 2:
By creating virtual copies of operator profiles that can be instantly instantiated and switched between, the system eliminates the time-consuming physical replacement process. Multiple operator profiles are stored as digital copies in the eUICC, allowing rapid switching by simply selecting the desired profile.
3Adaptability or versatility
If physical SIM card replacement is used, then operator switching is achieved, but costs for users increase
Solution Approach 1:
The patent applies universality by implementing a single eUICC that can store and manage multiple operator profiles, replacing the need for multiple physical SIM cards. The eUICC serves as a universal platform that can hold profiles from different operators, enabling users to switch between operators using one device instead of requiring separate physical SIM cards for each operator.
Solution Approach 2:
The system creates digital copies of operator profiles that can be stored and switched between without requiring physical SIM cards. Instead of needing multiple physical cards to represent different operators, the eUICC stores replicated profile data, reducing the quantity of physical substances (SIM cards) needed while maintaining full operator switching capability.
