Solution Overview

Problem

Current SIM card registration processes for terminal devices are complex and inefficient, requiring users to repeatedly verify identities when switching between service providers, which complicates user operations and affects user experience.

Innovation Solution

A method where a terminal device sends a subscription indication and identity to a second service provider server, allowing the server to acquire service registration information from a first service provider server, generating a new profile for accessing the second service provider network, thus enabling seamless registration without repeated identity verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a user subscribes to another service provider for registration, then the user can access a new service provider network, but the user must submit identity again for verification which makes registration operation complex and inefficient

Engineering Contradiction:

Improveservice provider switching capabilityVSAvoidregistration operation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by storing service registration information in the SIM card during the initial registration process. This pre-stored information is then reused when switching service providers, eliminating the need for repeated identity verification and simplifying the registration operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The service registration information stored in the SIM card serves multiple functions: it enables initial service provider registration, facilitates switching to new service providers, and provides authentication across different service provider networks. This multi-functionality resolves the contradiction by making the same data serve both adaptability and ease of operation needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a user subscribes to another service provider for registration, then the user can access a new service provider network, but repeated identity verification reduces registration efficiency

Engineering Contradiction:

Improveservice provider switching capabilityVSAvoidregistration efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the service registration information and stores it in the SIM card. This copied information can be efficiently reused across multiple service provider registrations, improving productivity by eliminating repeated verification processes while maintaining adaptability.

Inventive Principle:

Principle #26Copying

3Ease of operation

If service registration information is stored in the terminal device, then repeated verification is eliminated, but security risks may increase from information exposure

Engineering Contradiction:

Improveregistration operation simplicityVSAvoidinformation security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The SIM card serves as an intermediary security element that stores service registration information. It acts as a trusted mediator between the terminal device and service providers, providing secure storage and controlled access to sensitive information, thus maintaining reliability while enabling operational simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The service registration information is nested within the SIM card, which itself is embedded in the terminal device. This nested structure provides multiple layers of security protection, where the SIM card's secure environment protects the stored information while the terminal device provides an additional layer of physical and logical security.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

The embodiment provides a profile generation method, a profile acquisition method, a related device, and a storage medium. If a first subscriber identity module card in a terminal device has been registered with a first service provider, when a user needs to subscribe to a second service provider for registration, the terminal device sends a subscription indication and a subscription identity to a second service provider server, the second service provider server acquires service registration information from a first service provider server according to the subscription indication and the subscription identity, the service registration information is used by the first subscriber identity module card to access a first service provider network, the second service provider server generates a second profile for accessing a second service provider network based on the service registration information. Therefore, the second profile may be generated based on existing service registration information, so that the terminal device subscribes to the second service provider for registration. In this way, after the user performs subscription for registration once, the user does not need to submit an identity for verification again, so that user operations are simplified and user experience is improved.
