eUICC Profile Installation via OS Update for Partial Service Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eUICC modules face installation failures when trying to implement communication profiles that require services not supported by the module's operating system, leading to resource wastage and limited flexibility, resulting in potential premature obsolescence.
Innovation Solution
The method involves detecting unsupported services in a communication profile and requesting an operating system update to enable partial implementation of the profile, allowing the eUICC module to install and activate the profile, even if some services are not fully supported.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the eUICC module checks for service support before profile installation, then installation reliability is improved, but installation flexibility deteriorates because profiles requiring unsupported services are rejected
Solution Approach 1:
The patent applies partial action by allowing profile installation to proceed even when not all services are supported. The system checks for service support but permits installation to continue with partial functionality, enabling the terminal to use the profile for supported services while gracefully handling unsupported ones, thus balancing reliability with flexibility
Solution Approach 2:
The patent changes the parameter of service support requirements from binary (all or nothing) to graduated (partial support acceptable). By modifying the installation criteria to accept profiles with partial service support rather than requiring complete support, the system resolves the contradiction between reliable installation and flexible adaptability
2Loss of energy
If the eUICC module aborts profile installation when services are unsupported, then resource wastage is prevented, but device obsolescence accelerates
Solution Approach 1:
The patent enables partial profile implementation where the terminal can install and use supported services from a profile while ignoring or gracefully handling unsupported services. This approach prevents complete installation abortion, allowing the module to extend its operational lifespan by utilizing available services even when full profile functionality cannot be achieved
Solution Approach 2:
The patent treats individual services within a profile as separable units, allowing the terminal to discard unsupported services while retaining and using supported ones. This selective approach prevents the entire profile from being rejected due to minor service incompatibilities, thereby extending module utility
3Reliability
If the eUICC module requires full service support for profile installation, then service functionality is ensured, but device versatility is limited
Solution Approach 1:
The patent implements partial service functionality by allowing profiles to be installed and activated even when not all services are supported. The terminal identifies which services are supported and enables those while gracefully handling unsupported services, thus maintaining profile compatibility across diverse terminal capabilities without compromising the functionality of supported services
Solution Approach 2:
The patent creates a universal profile installation mechanism that works across terminals with varying service support capabilities. By designing the system to handle partial service support, a single profile can be universally deployed across different terminal types, with each terminal utilizing the services it supports while ignoring those it cannot handle

AI summary
The invention proposes a method of control in an embedded subscriber identity module (eUICCl) cooperating with a terminal (T), comprising: reception of identifiers (ID) of services associated with a communication profile (P), to be executed when the profile is in the active state; determination of whether each service (S) is supported by an operating system (OS1) of the embedded subscriber identity module (eUICCl); in the negative, dispatching of a request to update the operating system (OS1); installation of said update allowing the operating system to implement the communication profile (P); and dispatching of a request to receive or continue the reception of the communication profile (P) to be installed in said embedded subscriber identity module (eUICCl). The invention also relates to a method of control implemented by a profile provision server so as to provide the service identifiers to the embedded subscriber identity module (eUICCl).
