Virtual Resource Sharing Control for Dual SIM Mobile Terminals

The patent introduces a virtual resource sharing control system as an intermediary layer between multiple operating systems and the physical SIM card resources. This virtual system abstracts and manages radio resources, channel resources, and SIM card operations, allowing multiple OSes to access shared resources without direct conflicts. The virtual resource sharing control system coordinates resource allocation, monitors usage status, and prevents allocation conflicts among concurrent operating systems.

The patent implements a feedback mechanism where the virtual resource sharing control system continuously monitors the usage status of SIM cards and channel resources across multiple operating systems. The system collects status information from each OS, processes it centrally, and distributes updated status information back to all relevant operating systems. This feedback loop ensures that all operating systems maintain consistent views of resource usage status, enabling coordinated management and preventing conflicts.

The patent segments the resource management function into two independent but coordinated parts: each operating system retains independent control over its own resource management operations (maintaining ease of operation), while the virtual resource sharing control system provides segmented monitoring and coordination of shared physical resources (ensuring reliability). This segmentation allows each OS to operate independently with full functionality while the virtual layer ensures reliable resource allocation by preventing conflicts and coordinating access to shared SIM card and channel resources.
