Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing eSIM activation methods require eSIM-capable devices to connect to a wireless service provider's SMDP server via a network, which can be problematic when a network connection is unavailable, preventing eSIM activation.

Innovation Solution

The method involves using a peer-to-peer (P2P) connection for an eSIM-capable device to receive an eSIM profile and eUICC management commands from another device acting as a proxy, allowing eSIM activation without direct network connection to the SMDP server, utilizing GSMA-defined ES9+ and ES10 APIs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If eSIM activation requires connection to SMDP server via network, then eSIM profile can be downloaded and activated, but activation cannot proceed when network connection is unavailable

Engineering Contradiction:

ImproveeSIM activation reliabilityVSAvoidactivation environment flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a second device as an intermediary that downloads the eSIM profile from the SMDP server and transfers it to the eSIM-capable device via P2P connection. This mediator enables profile delivery when the target device cannot directly access the network, resolving the contradiction between reliable activation and environmental flexibility.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the activation dimension from direct network connection to indirect P2P transfer. By moving the profile delivery process to a different dimensional approach (device-to-device rather than device-to-server), activation becomes possible in environments where traditional network access is unavailable.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If conventional SIM activation is used, then activation can occur without network connection, but eSIM functionality cannot be implemented

Engineering Contradiction:

Improveactivation method flexibilityVSAvoidSIM card infrastructure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a copy of the conventional SIM activation experience by allowing profile transfer through P2P connection, mimicking the card-handoff process. This copying approach maintains the simplicity and flexibility of conventional SIM activation while implementing eSIM functionality without requiring network connection or physical SIM cards.

Inventive Principle:

Principle #26Copying

3Ease of operation

If P2P connection is used for eSIM profile transfer, then activation can occur without network connection, but direct server communication is eliminated

Engineering Contradiction:

Improveactivation process simplicityVSAvoiddirect server authentication

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent performs preliminary authentication and profile preparation on the second device before P2P transfer. The SMDP server authentication, profile generation, and security validations are completed in advance, ensuring that no critical authentication information is lost during the indirect transfer process.

Inventive Principle:

Principle #10Preliminary action

AI summary

eSIM activation using peer-to-peer (P2P) communication includes receiving by an eSIM-capable device an eSIM profile from another device, the eSIM profile retrieved from a subscription manager data preparation (SMDP) server via a network. The eSIM profile is received by the eSIM-capable device from the other device via the P2P connection. The eSIM-capable device performs an eSIM activation based on the eSIM profile from the other device.
