Solution Overview

Problem

The accuracy of processing results for eUICCs is generally low due to the reliance on initial information during profile generation and management procedures, which does not account for the capabilities of the terminal in which the eUICC is embedded.

Innovation Solution

The eUICC acquires and sends capability information, such as radio access technology and service domain support, to an SM platform, allowing it to manage or generate profiles that adapt to the terminal's capabilities, ensuring accurate configuration and management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the SM platform manages profiles based on initial EIS information from factory registration, then the processing procedure is simple, but the accuracy of processing results is low

Engineering Contradiction:
Improveaccuracy of processing resultsVSAvoidcomplexity of information collection
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The terminal performs preliminary detection of its own capability information (supported RAT types, concurrent working capabilities, service domain support) before profile management operations. This preliminary action ensures that accurate capability data is available when needed for profile generation and management, improving accuracy without requiring complex real-time information collection during profile operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal provides feedback to the SM platform by reporting its capability information. The SM platform uses this feedback to accurately match and manage profiles that are compatible with the terminal's actual capabilities. This feedback mechanism ensures that profile management decisions are based on accurate, up-to-date terminal capability information rather than relying solely on initial factory registration data.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the terminal capability information is not collected, then the processing procedure is fast, but the profile compatibility with terminal is poor

Engineering Contradiction:
Improveprofile compatibilityVSAvoidtime for information acquisition
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The terminal acquires its capability information in advance and makes it available for profile management operations. By performing this information acquisition action preliminarily, the system avoids time delays during actual profile management while ensuring accurate terminal-capable profile matching.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal autonomously detects and reports its own capability information to the SM platform without requiring external probing or complex interaction protocols. This self-service approach minimizes the time required for information acquisition while ensuring that accurate capability data is provided for profile compatibility assessment.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If initial EIS information is used for profile generation, then the processing efficiency is high, but the accuracy of configuration is low

Engineering Contradiction:
Improveaccuracy of configurationVSAvoidprocessing efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The terminal provides feedback about its actual capability information to the SM platform, which uses this feedback to accurately generate and manage profiles. This feedback ensures that profile configurations are precisely matched to terminal capabilities, improving manufacturing precision without significantly impacting processing efficiency since the capability information is readily available.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system transitions from using static initial EIS information to using dynamic terminal capability parameters. By changing the informational parameters from factory-default values to actual terminal capabilities, the system achieves more accurate profile configurations while maintaining efficient processing through the use of structured capability data formats.

Inventive Principle:
Principle #35Parameter changes

AI summary

The présent invention provides an eUICC management method, an eUICC, an SM platform, and a system. The method includes: acquiring, by an eUICC, capability information of a terminal in which the eUICC is embedded; and sending, by the eUICC, the capability information of the terminal to an SM, so that the SM manages a configuration file profile on the eUICC or generates a profile or manages the eUICC according to the capability information of the terminal. Capability information of a terminal in which the eUICC is embedded is reported to an SM, so that processing such as génération or management of a configuration file can adapt to the capability information of the terminal, which improves processing accuracy.
