Solution Overview

Problem

Existing methods for provisioning eSIM profiles for new subscribers using existing eSIM-capable UEs are cumbersome, time-consuming, and prone to error, as they require oral or manual input of a 32-digit EID to customer service representatives.

Innovation Solution

A method where a user equipment (UE) sends a request to reserve an eSIM profile, receives a request for an identifier, selects and encodes the identifier, and transmits the encoded identifier to reserve the eSIM profile, eliminating the need for human intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a subscriber orally conveys or manually inputs the 32-digit EID to a customer service representative, then the eSIM profile can be reserved, but the process becomes cumbersome, time-consuming, and prone to error

Engineering Contradiction:
Improveaccuracy of EID transmissionVSAvoidsimplicity of eSIM reservation process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the manual/oral input mechanism with an automated audio encoding and transmission system. The device captures audio containing the EID, encodes it into a structured format, and transmits it automatically to the network operator's system, eliminating the need for manual typing or oral communication with customer service representatives.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables subscribers to independently reserve eSIM profiles by using their own device's audio capture and encoding capabilities. The automated processing allows the subscriber to complete the reservation process without human intervention from customer service personnel, making the system self-serving.

Inventive Principle:
Principle #25Self-service

2Productivity

If the device OEM transmits device inventory field files to the network operator, then EIDs can be ingested efficiently, but this method is unavailable for new subscribers with existing eSIM-capable UEs

Engineering Contradiction:
Improveefficiency of EID ingestionVSAvoidapplicability to different subscriber scenarios
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal solution that works for both new subscribers with existing eSIM-capable devices and traditional scenarios. The audio-based EID transmission method can be used by any subscriber regardless of their acquisition channel, making the system adaptable to multiple use cases including self-service reservations and bulk provisioning.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If a subscriber engages with a customer service representative to reserve an eSIM profile, then assistance is provided, but time is lost and errors may occur in conveying the identifier

Engineering Contradiction:
Improveavailability of customer supportVSAvoidduration of eSIM reservation process
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system empowers subscribers to independently complete the eSIM reservation process by automatically capturing, encoding, and transmitting their EID through audio input. This eliminates the need to wait for customer service representative availability and significantly reduces the time required to complete the reservation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The automated system provides immediate processing and confirmation of the EID transmission, giving real-time feedback to the subscriber about the reservation status. This eliminates the back-and-forth communication delay inherent in manual customer service interactions.

Inventive Principle:
Principle #23Feedback

AI summary

In various examples, a user seeking to switch network providers may reserve an eSIM profile through touch selection of the display of a UE, which causes encoding and transmission of an identifier associated with the UE to a network operator. As a result, human error both in transmitting and receiving the identifier needed to reserve an eSIM profile is eliminated. And the time needed to identify and transmit the identifier is significantly reduced in comparison to orally conveying the identifier to a customer services representative or keying in the identifier, and then verifying the identifier with the representative.
