Hardware Capability Update for Multi-SIM Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In portable devices with multiple SIM cards, the hardware resources are fixed, leading to reduced efficiency and fluency of operation when one SIM card's service is executed, as the reported hardware capability of the second SIM card is not adjusted accordingly.
Innovation Solution
A hardware-capability update method and device that dynamically updates the hardware capability for multiple SIM cards by detecting the need for updates, determining immediate responsiveness, transmitting current capability information, and storing pending updates when immediate response is not possible, using a controller and hardware management circuit to manage resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the hardware capability for the first SIM card is reported immediately, then the response speed to the requesting terminal is improved, but the accuracy of hardware capability information deteriorates because the hardware resources are already reduced by the first SIM card's service
Solution Approach 1:
The system performs preliminary detection to determine whether hardware capability information needs to be updated before reporting. The controller checks if the first SIM card's service has occupied hardware resources and whether the second SIM card's hardware capability needs to be updated accordingly, preventing inaccurate information from being reported in the first place
Solution Approach 2:
The system implements a feedback mechanism where the controller continuously monitors the hardware resource usage status of the first SIM card and uses this feedback to determine when to update the hardware capability information for the second SIM card, ensuring accuracy while managing response timing
2Productivity
If the hardware capability information is updated dynamically, then the efficiency and fluency of operation are improved, but the device complexity increases due to the need for continuous monitoring and updating mechanisms
Solution Approach 1:
The controller is designed to perform multiple functions: it manages hardware resources for multiple SIM cards, detects when updates are needed, determines whether immediate response is possible, and executes the appropriate update strategy. This multi-functionality reduces the need for separate dedicated components for each task
Solution Approach 2:
The system performs self-monitoring and self-updating of hardware capability information. The controller automatically detects changes in hardware resource usage and triggers updates when necessary, without requiring external intervention or complex manual management mechanisms
3Device complexity
If the hardware capability is not updated when immediately responsive, then the device complexity is reduced, but the loss of time increases due to delayed updates
Solution Approach 1:
The system applies partial action by updating hardware capability information selectively rather than continuously. The controller determines whether an update is actually needed based on the current service status, performing updates only when necessary rather than at every opportunity, thus balancing timeliness with simplicity

AI summary
A hardware-capability update method for a portable device with at least first and second SIM cards is provided. The method includes detecting whether a hardware capability for a first SIM card has to be responded to a requesting terminal; determining whether the hardware capability for the first SIM card can be responded immediately; transmitting the information about hardware capability to the requesting terminal when the hardware capability for the first SIM card can be responded immediately; and storing the information about pending updated hardware capability when the hardware capability for the first SIM card cannot be responded immediately.
