eUICC Version Negotiation via HTTPS Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems face challenges in efficiently providing services due to the inconvenience of physical SIM card management, especially when users need to access different mobile communication operators, leading to issues with roaming and compatibility between service providers.
Innovation Solution
The implementation of an embedded universal integrated circuit card (eUICC) that can remotely download and select SIM modules, allowing terminals to negotiate eUICC versions through HTTPS connections with servers to determine compatible profiles and perform authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical SIM cards are used for accessing different mobile communication operators, then service access is achieved, but user convenience deteriorates due to the need for physical SIM card changes and management
Solution Approach 1:
The patent extracts the SIM card functionality from its traditional physical form and relocates it to a remote server environment. The eUICC (embedded universal integrated circuit card) is implemented as a virtualized component that can be remotely provisioned and managed, eliminating the need for physical SIM card handling while maintaining all essential telecommunication functions.
Solution Approach 2:
The patent introduces an intermediary system consisting of the eUICC and remote server infrastructure that mediates between the user device and mobile communication operators. This intermediary enables seamless switching between operators and services without requiring physical SIM card changes, as the eUICC can be remotely reconfigured to access different network providers.
2Reliability
If physical SIM cards are used for roaming between operators, then service compatibility is achieved, but service continuity deteriorates due to roaming issues and compatibility problems
Solution Approach 1:
The patent implements a universal eUICC architecture that can function with multiple mobile communication operators and service providers simultaneously. The eUICC is designed to be operator-agnostic, allowing it to adapt to different network protocols and service requirements, thereby ensuring both service continuity and broad compatibility across various operators without roaming issues.
3Adaptability or versatility
If eUICC version negotiation is implemented through HTTPS connections, then service compatibility improves, but communication overhead increases
Solution Approach 1:
The patent implements preliminary version negotiation during the initial HTTPS connection establishment between the terminal and server. By determining eUICC version compatibility in advance through version information exchange in the HTTPS headers, the system avoids repeated negotiation overhead during subsequent communications, thereby reducing overall communication time while ensuring compatibility.

AI summary
A method, performed by a terminal, of negotiating an embedded universal integrated circuit card (eUICC) version in a wireless communication system includes: establishing a hypertext transfer protocol over secure socket layer (HTTPS) connection with a server transmitting eUICC information including information about the eUICC version to the server through the HTTPS connection; and receiving server information corresponding to the eUICC information from the server, wherein the information about the eUICC version includes a minimum eUICC version and a maximum eUICC version that are available when the terminal accesses the server.
