SIM Card Management System for Dynamic Resource Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals struggle with effective management and scheduling of SIM card resources, leading to limitations in the number of SIM cards that can be used, manual replacement requirements, and inefficient resource utilization.
Innovation Solution
A device and system for managing and scheduling SIM card resources, which includes a card service module, a card management interface module, and a card physical interface module. This system allows for dynamic management and allocation of SIM cards, enabling operations such as loading, sharing, enabling, disabling, and monitoring of SIM cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If SIM cards are loaded directly into the modem, then the modem can access the SIM card quickly, but the number of SIM cards that can be used is limited due to limited physical interfaces
Solution Approach 1:
The patent introduces a card management module as an intermediary layer between the SIM cards and the modem. This module manages multiple SIM cards (stored in a SIM card box) and loads them into the modem as needed, acting as a mediator that decouples the limited modem interfaces from the potentially large number of SIM cards a user may possess.
Solution Approach 2:
The system separates SIM card storage and management functions from the modem itself. The SIM card box stores multiple SIM cards independently, while the card management module handles the coordination of loading specific SIM cards into the modem, dividing the system into distinct functional components.
2Adaptability or versatility
If SIM cards are manually replaced, then the user can switch between different SIM cards, but the unplugged SIM card cannot be used for dialing or receiving calls
Solution Approach 1:
Multiple SIM cards are pre-loaded into the SIM card box in advance. When the user wants to switch SIM cards, the card management module can quickly load the desired SIM card from the pre-stored options, eliminating the need for manual physical replacement and ensuring minimal interruption to service.
Solution Approach 2:
The card management module automatically handles the SIM card switching process based on user selection or system requirements, performing the loading and configuration tasks without requiring manual intervention for physical card replacement.
3Reliability
If the mobile terminal is powered up to use a SIM card, then the SIM card can be accessed, but the SIM card resources cannot be effectively scheduled when not in use
Solution Approach 1:
The system implements dynamic SIM card management where the card management module can load, switch, and unload SIM cards based on real-time needs. SIM cards are loaded into the modem only when required for use, and can be unloaded when not needed, allowing flexible resource allocation and improving overall utilization efficiency while maintaining reliability when access is needed.
4Ease of operation
If physical SIM cards are used, then the SIM card can be inserted and removed, but the SIM card cannot be shared with other devices
Solution Approach 1:
The system enables SIM card sharing by creating a copy or representation of the SIM card's authentication credentials (such as IMSI and authentication keys) that can be transmitted to other devices. The card management module extracts and transmits these credentials, allowing the SIM card's identity and access rights to be replicated for use in other communication devices without physically moving the SIM card itself.
