Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for transferring an embedded universal integrated circuit entity between mobile network operators are costly, inflexible, and lack efficient security measures, particularly when dealing with machine-type communication devices and consumer products, where changes in network operators or user ownership occur.
Innovation Solution
A method that initializes and transfers the embedded universal integrated circuit entity within an electronic device using a specific repository to store and manage subscription and logging information, allowing seamless transitions between mobile network operators, with the ability to decouple initialization and activation steps, and support indirect transfers through multiple operators, ensuring secure and cost-effective operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional methods are used to transfer embedded universal integrated circuit entities between mobile network operators, then security is maintained, but costs increase and flexibility decreases
Solution Approach 1:
The patent introduces a repository as an intermediary component that stores subscription information and logging data for embedded universal integrated circuit entities. This repository acts as a mediator between mobile network operators, enabling them to transfer assignments of embedded UICCs without direct complex interactions. The repository stores essential information (subscription data, logging information) that allows operators to assume control of embedded UICCs from other operators, thereby reducing transfer costs and increasing flexibility while maintaining security through controlled information access.
2Ease of operation
If embedded universal integrated circuit cards are integrated permanently into user equipment, then size and accessibility improve, but initialization and provisioning become problematic
Solution Approach 1:
The patent implements preliminary action by pre-configuring a repository structure that can store subscription information and logging data before the embedded universal integrated circuit entity is fully activated. The system prepares the infrastructure (repository with appropriate data structures and access controls) in advance, allowing seamless initialization when the embedded UICC is first deployed. This preliminary setup enables automatic provisioning without manual intervention, solving the manufacturing complexity issue while maintaining the benefits of embedded cards.
Solution Approach 2:
The patent enables self-service mechanisms where the embedded universal integrated circuit entity can be automatically initialized and provisioned through interactions with the repository. The system allows the embedded UICC to self-configure by retrieving necessary subscription information from the repository, eliminating the need for manual initialization processes. This self-service capability resolves the provisioning complexity while maintaining the compact embedded form factor.
3Productivity
If a specific repository is introduced to manage subscription information, then transfer efficiency improves, but system complexity increases
Solution Approach 1:
The patent implements universality by designing the repository as a multi-functional system that handles multiple operations within a single infrastructure. The repository not only stores subscription information but also maintains logging data, manages access controls, and supports transfers between multiple mobile network operators. By consolidating these functions into a single universal repository, the system improves transfer efficiency without proportionally increasing complexity, as the same infrastructure serves multiple purposes.
Solution Approach 2:
The patent applies homogeneity by standardizing the repository structure and data formats across different mobile network operators. The repository uses uniform data structures for subscription information and logging data, regardless of which operator owns the embedded UICC. This homogeneous approach simplifies the transfer process between operators, as the repository interface remains consistent, thereby improving productivity without adding significant complexity.

AI summary
The invention relates to a method for transferring an assignment regarding an embedded universal integrated circuit card within an electronic device from a first mobile network i operator to a second mobile network operator, wherein the embedded universal integrated circuit card is integrated in the electronic device: in a first step, the embedded universal integrated circuit card is initialized, together with the electronic device, to be used with the first mobile network operator; in a second step, the assignment regarding the embedded universal integrated circuit card is transferred from the first mobile network operator to the second mobile network operator, wherein the first subscription related information and/or the first logging related information of the specific repository is accessed by the second mobile network operator.
