Solution Overview

Problem

Current systems for managing Embedded Subscriber Identity Module (eSIM) profiles lack the ability for wireless communication carriers to directly initiate and manage profile state changes, leading to delays in resolving subscriber telecommunication service outages due to incorrect eSIM profile states, which can result in reduced customer satisfaction and increased operational inefficiencies.

Innovation Solution

An eSIM management platform that enables wireless communication carriers to initiate subscription management services for individual or batch updates of eSIM profile states, using validation tables to ensure permissible changes and prevent accidental or intentional cloning, thereby allowing direct management of eSIM profiles without relying on help desk support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless communication carriers use help desk support to manage eSIM profile state changes, then operational procedures are simplified, but problem resolution time increases and operational efficiency decreases

Engineering Contradiction:
Improveoperational procedure simplicityVSAvoidproblem resolution efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent enables wireless communication carriers to directly initiate and manage eSIM profile state changes through the subscription management service without requiring help desk support. The carrier can autonomously update profile states, resolve outages, and manage subscriber services directly, transforming the system from a service-dependent model to a self-service model that improves both ease of operation and productivity

Inventive Principle:
Principle #25Self-service

2Reliability

If eSIM profile state changes are managed through help desk support, then centralized control is maintained, but response time to resolve service outages increases

Engineering Contradiction:
Improvecentralized controlVSAvoidproblem resolution time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by enabling the subscription management service to proactively initiate profile state changes based on pre-configured conditions and carrier instructions. The system can prepare and execute state updates in advance or immediately upon detecting issues, reducing response time while maintaining controlled updates through validation tables that ensure permissible changes

Inventive Principle:
Principle #10Preliminary action

3Reliability

If validation tables are implemented to prevent profile cloning, then security and reliability improve, but system complexity increases

Engineering Contradiction:
Improveprofile state management reliabilityVSAvoidsystem structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces validation tables as intermediary structures that mediate between the carrier's profile state change requests and the actual profile updates. These validation tables act as a control layer that defines permissible transitions and prevents cloning by validating each state change against predefined rules, thereby improving reliability while keeping the complexity manageable through structured rather than ad-hoc validation mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The techniques provide a wireless communication carrier with the ability to directly initiate a subscription management service to perform profile state changes with respect to eSIM profile states that are maintained by the subscription management service. A profile transition request is received from an entity at an eSIM management platform. The profile transition request includes a profile state change for an eSIM profile from a first profile state to a second profile state. The requested profile state change is validated using a validation table of permissible profile state changes that is common to the eSIM management platform and the subscription management service. The profile transition request is sent to the subscription management service in response to the validation of the profile state change.
