Solution Overview

Problem

Users face challenges in efficiently swapping SIM cards or eSIM profiles across different cellular networks, leading to time-consuming and costly migrations, especially during network acquisitions or mergers, and traditional methods require user intervention.

Innovation Solution

A system and method for cellular networks to identify and push eSIM profiles to user devices, enabling seamless migration and upgrade of eSIM functionality without the need for physical SIM card swapping, using a Subscription Manager-Data Preparation (SM-DP+) platform to manage and distribute eSIM profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional physical SIM card swap methods are used, then users can migrate between networks, but the process requires physical visits or mail-based exchanges which increases time consumption and costs

Engineering Contradiction:

ImproveSIM card migration processVSAvoidMigration time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical physical SIM card swapping process with an electronic/digital system. The eSIM profile is downloaded and installed electronically through a download identifier received from the new network, eliminating the need for physical SIM card handling, store visits, or mail exchanges. This substitution of mechanical operations with electronic processes directly resolves the contradiction by making migration instantaneous and remote.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional physical SIM card methods are used, then users can access cellular networks, but physical SIM cards can be lost or stolen creating security risks

Engineering Contradiction:

ImproveNetwork access reliabilityVSAvoidSecurity risks from lost or stolen SIM cards

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent eliminates physical SIM cards entirely and replaces them with an embedded eSIM system where the profile is downloaded electronically. The eSIM is permanently embedded in the device and cannot be physically removed or lost like traditional SIM cards. The profile can be remotely managed and deactivated by networks, providing enhanced security control and eliminating the risk of physical theft or loss while maintaining reliable network access.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If users need to migrate to a new network, then service continuity can be maintained, but traditional methods require user initiation and store visits which increases operational complexity

Engineering Contradiction:

ImproveNetwork migration capabilityVSAvoidMigration process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables automated network migration where the new network can initiate and complete the eSIM profile installation without requiring user action. The system automatically provides a download identifier to the device, and the eSIM profile is downloaded and installed in the background. This self-service automation eliminates the need for users to visit stores or manually initiate complex migration procedures, reducing operational complexity while maintaining network adaptability.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If physical SIM cards are used, then users can swap between carriers, but the process requires manual intervention and customer care involvement which increases costs

Engineering Contradiction:

ImproveCarrier switching capabilityVSAvoidMigration cost

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent replaces manual SIM card swapping operations with an automated electronic profile download system. The eSIM profile is downloaded and installed through automated electronic communication between networks, eliminating the need for customer care involvement, store visits, or manual intervention. This automation significantly reduces the operational costs associated with carrier switching while maintaining full carrier switching capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A system identifies devices to be migrated from a first network to a second network. Identifying the devices includes determining that the devices are eSIM-capable of being upgraded to operate using the second network. For each device, an eSIM profile is determined. Each device has a SIM card or a previous eSIM profile installed. The eSIM profile matches a level of service to be provided to the device by the second cellular network. The eSIM profile is pushed to the device. The eSIM profile is downloaded and installed on the device. The system determines that the eSIM profile has been installed on the device. The level of service to be provided to the device is enabled on the eSIM profile. The SIM card or previous eSIM profile on the device is disabled.
