eSIM Card Pool System for Automated Operator Profile Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing SIM card pool technology requires significant human intervention for management, especially when dealing with large numbers of physical SIM cards, making it cumbersome and time-consuming to add new operators or scale the system, as each SIM card corresponds to a specific operator and needs to be replaced.
Innovation Solution
An eSIM-based card pool system that uses a provisioning manager, EID status manager, connection manager, and eSIM card pool unit to manage and change operator profiles on eSIM cards without physical replacement, enabling software-controlled management and scalable expansion through eSIM cards and trusted execution environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical SIM cards are used in a card pool system, then operator-specific SIM cards can be stored and managed, but manual intervention is required for purchasing, verification, physical installation, and replacement, making management cumbersome and time-consuming when dealing with large numbers of cards
Solution Approach 1:
The patent replaces the mechanical system of physical SIM card handling with an electronic/digital system. eSIM cards are embedded in terminals and can be remotely provisioned and managed through software, eliminating the need for physical purchasing, verification, installation, and replacement operations. The card pool system manages eSIM profiles electronically, allowing automated distribution and switching between operators without manual physical card handling.
2Adaptability or versatility
If physical SIM cards are used with one-to-one correspondence to operators, then each operator has dedicated SIM cards, but new SIM cards must be purchased and physically replaced when adding operators or scaling the system
Solution Approach 1:
The patent uses eSIM technology where multiple operator profiles can be stored as digital copies within the same eSIM card. Instead of requiring physical SIM card copies for each operator, the system electronically stores and switches between operator profiles. When adding new operators or scaling the system, new profile copies are downloaded and activated remotely without physical card replacement, enabling rapid system expansion.
3Quantity of substance
If the card pool system scales to tens of millions or hundreds of millions of cards, then coverage and service capacity increase, but manual management becomes almost impossible
Solution Approach 1:
The patent replaces manual mechanical management with automated electronic management systems. The card pool system uses software-based provisioning, verification, distribution, and monitoring of eSIM cards. Automated algorithms handle card activation, profile distribution, balance monitoring, and operator management at scale, enabling the system to efficiently manage tens of millions or hundreds of millions of cards without human intervention.

AI summary
An eSIM-based card pool system is disclosed, the system comprising: a card pool unit comprising a plurality of eSIMs; an eSIM manager, comprising a database that stores corresponding relationships between a plurality of eSIM identifications and a plurality of eSIM addresses; and a connection manager, configured to request a first eSIM address from the eSIM manager based on a received download instruction, and write a specified eSIM profile into a first eSIM having the first eSIM address.
