Problem

Existing RSP servers cannot perform local profile management in scenarios with multiple profiles across different operating systems (OSs).

Innovation Solution

The implementation of an embedded universal integrated circuit card (eUICC) with an Issuer Security Domain Root (ISD-R) on a primary platform, allowing for profile management across multiple OSs through the Local Profile Assistant (LPA) and profile policy enabler (PPE).

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an existing RSP server is used for profile management, then profile management is simple and straightforward, but it cannot perform local profile management in multi-OS multi-profile scenarios

Engineering Contradiction:
Improveprofile management capabilityVSAvoidsystem architecture
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the profile management system into multiple independent components: a processing module on the primary platform that handles cross-OS profile management operations, and individual OS instances that each manage their own profiles. This segmentation allows the system to handle multi-OS multi-profile scenarios by dividing the management function across different operational contexts rather than requiring a single monolithic management system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a processing module as an intermediary between the user interface and the multiple operating systems. This intermediary receives user instructions, determines the target OS, and executes profile management operations accordingly. The intermediary enables coordinated management across multiple OS instances without requiring direct complex interactions between them.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple profiles are installed in multiple OSs, then profile selection flexibility is improved, but existing RSP servers cannot manage these profiles locally

Engineering Contradiction:
Improveprofile selection flexibilityVSAvoidlocal profile management
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements dynamic profile management where the system can adaptively route profile management operations to the appropriate OS instance based on real-time conditions. The processing module dynamically determines which OS should handle a given profile operation, enabling flexible management of profiles across multiple dynamic OS environments rather than static single-OS management.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The processing module is designed with universal functionality to handle profile management operations across different types of operating systems. It can manage profiles in any installed OS instance, making the profile management capability universal rather than OS-specific, thereby enabling ease of operation across multi-OS environments.

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

3Ease of operation

If a processing module is added to handle multi-OS profile management, then local profile management capability is improved, but system complexity increases

Engineering Contradiction:
Improvelocal profile management capabilityVSAvoidsystem structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where each operating system instance maintains its own profile data and state information. When a profile management operation is requested, the processing module queries the target OS instance for its current state and executes the operation locally within that OS context. This self-service approach reduces the need for complex centralized management logic while enabling local profile management capability.

Inventive Principle:
Principle #25Self-service

AI summary

Embodiments of the present invention provide a local profile management method, an embedded universal integrated circuit card, and a terminal. The embedded universal integrated circuit card eUICC includes a primary platform and at least one installed bundle. The at least one installed bundle is (are) provided by different operators. The primary platform is a hardware platform. Each bundle includes at least one profile and an operating system OS. The primary platform includes a processing module. The processing module is configured to: receive a first message sent by a local profile assistant LPA, where the first message is an operation instruction entered by a user; and separately send a second message to at least one OS corresponding to the at least one bundle, where the second message is used by the at least one OS to perform a corresponding operation. Local management of profiles of different OSs is implemented by using the processing module disposed on the primary platform of the eUICC.
