Multi-SIM Resource Management via Automatic Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-card terminals lack intelligent resource management, leading to degraded user experience as they do not automatically switch to SIM cards with sufficient service resources when a current SIM card's resources reach a limit, requiring manual user intervention.
Innovation Solution
A multi-card resource management method and device that automatically switches to a SIM card with sufficient service resources by acquiring a list of SIM cards, inquiring for available resources, and selecting based on priority or remaining amount, eliminating the need for manual user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual switching is implemented when service resource reaches limit, then user is notified, but intelligent management and scheduling cannot be performed
Solution Approach 1:
The system performs self-service by automatically monitoring service resource levels and switching SIM cards without user intervention. The management application autonomously checks resource thresholds and executes switching decisions based on predefined criteria, eliminating the need for manual user action while maintaining intelligent resource management.
Solution Approach 2:
The system performs preliminary actions by pre-configuring switching criteria and resource thresholds. Before resource depletion occurs, the system continuously monitors service resource levels and prepares switching decisions in advance, ensuring seamless transition when limits are approached without requiring real-time user input.
2Adaptability or versatility
If independent management applications are used for each SIM card, then resource management is simple, but intelligent scheduling considering other resources cannot be performed
Solution Approach 1:
The system merges multiple independent SIM card management functions into a single unified management application. This consolidated application monitors and manages resources across all SIM cards simultaneously, enabling intelligent scheduling decisions that consider the state of multiple resources and cards together, rather than managing each card in isolation.
Solution Approach 2:
The management application achieves multi-functionality by handling resource monitoring, threshold evaluation, switching decisions, and execution for multiple SIM cards through a single system. This universal approach allows the same application to manage different service resources (data, voice, SMS) across different cards with a unified intelligent scheduling mechanism.

AI summary
A multiple subscriber identity module cards (multi-SIM) resource management method, device and multi-SIM terminal. The method comprises: acquiring a subscriber identity module card list in a terminal, the subscriber identity module card list comprising all subscriber identity module cards in the terminal; and if a remaining quantity of a service resource on a subscriber identity module card currently used in the terminal is less than or equal to a preset remaining quantity threshold, then automatically switching to a subscriber identity module card having a sufficient service resource and in the subscriber identity module card list.
