Solution Overview

Problem

In In-Factory Provisioning of eUICCs, the lack of an online connection to a remote profile server or Operator server prevents timely notification of profile downloads and installations to the Operator, leading to delayed information updates and potential inconsistencies, increasing transaction costs and error risks.

Innovation Solution

The method involves generating and providing notifications at the Personalization Equipment instead of the eUICC or Local Profile Assistant, allowing for immediate notification to a remote entity after profile downloads, even in offline scenarios, by utilizing the Personalization Equipment to manage and transmit notifications directly to the Operator or profile server.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If profile download is performed in In-Factory Provisioning mode without online connection to remote profile server, then offline provisioning capability is improved, but notification timeliness deteriorates

Engineering Contradiction:
Improveoffline provisioning capabilityVSAvoidnotification timeliness
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent introduces the Personalization Equipment as an intermediary entity that generates and forwards notifications on behalf of the eUICC. This mediator enables notification functionality in offline scenarios by decoupling the notification generation from direct eUICC-Operator server communication, thus resolving the contradiction between offline provisioning capability and notification timeliness

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The notification is generated preliminarily at the Personalization Equipment immediately after profile download, rather than waiting for eUICC to connect to the Operator server. This preliminary action ensures timely notification while maintaining offline provisioning capability

Inventive Principle:
Principle #10Preliminary action

2Reliability

If notification is generated by eUICC or Local Profile Assistant, then notification accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvenotification accuracyVSAvoideUICC operational requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The Personalization Equipment serves as an intermediary that generates notifications with the same accuracy as eUICC-generated notifications but without requiring eUICC to be operational. This transfers the notification generation responsibility from the eUICC to the personalization equipment, reducing device complexity while maintaining notification accuracy

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The Personalization Equipment performs the notification generation function that would otherwise require eUICC participation, allowing the system to serve itself without requiring the eUICC to be active or connected to external networks

Inventive Principle:
Principle #25Self-service

3Reliability

If eUICC operation is required for notification, then notification reliability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvenotification delivery reliabilityVSAvoidprovisioning operation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The notification is generated in advance at the Personalization Equipment before eUICC operation is required. This preliminary generation of notifications eliminates the need for subsequent eUICC operation to deliver notifications, thus improving ease of operation while maintaining reliability through the established notification forwarding mechanism

Inventive Principle:
Principle #10Preliminary action
