Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple subscriber identity modules (SIMs) face increased complexity and current consumption due to unnecessary dual connectivity, which affects the quality of data communication.
Innovation Solution
The electronic device selectively activates or deactivates dual connectivity based on the connected state of each SIM, optimizing communication with one SIM for data and switching to an idle state with another SIM not in use, thereby reducing complexity and enhancing communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device simultaneously supports dual connectivity through communication protocol stacks related to multiple subscriber identity modules, then the device can perform wireless communication with multiple cellular networks, but the complexity (hardware and software) and current consumption increase
Solution Approach 1:
The patent segments the dual connectivity support by subscriber identity module. Instead of implementing full dual connectivity for all SIMs simultaneously, the system enables dual connectivity only for the active data communication session, while other SIMs operate in simplified mode. This segmentation reduces the overall protocol stack complexity while maintaining versatility.
Solution Approach 2:
The patent implements dynamic capability updates where the device can switch between different operational modes (full dual connectivity vs. simplified mode) based on the active SIM and network conditions. This dynamic adjustment allows the device to optimize complexity and power consumption according to actual usage scenarios.
2Adaptability or versatility
If the electronic device simultaneously supports dual connectivity through communication protocol stacks related to multiple subscriber identity modules, then the device can perform wireless communication with multiple cellular networks, but current consumption increases
Solution Approach 1:
The patent segments the power consumption by limiting dual connectivity operations to only the active data communication session. Other subscriber identity modules operate without full dual connectivity capabilities, significantly reducing the overall current consumption while preserving the ability to communicate with multiple networks when needed.
Solution Approach 2:
The system dynamically adjusts its operational mode based on which SIM is active and network conditions. When dual connectivity is not needed for the current data session, the device transitions to a lower-power mode, optimizing energy efficiency while maintaining network versatility when required.
3Reliability
If dual connectivity is maintained for all subscriber identity modules, then communication availability is maximized, but the quality of data communication deteriorates due to unnecessary dual connectivity
Solution Approach 1:
The patent segments dual connectivity support by subscriber identity module, enabling it only for the active data communication session. This ensures that resources are allocated efficiently to the currently active SIM, improving data communication quality by eliminating interference from unnecessary dual connectivity operations on other SIMs.
Solution Approach 2:
The system dynamically activates or deactivates dual connectivity based on the active SIM and network conditions. This dynamic control optimizes data communication quality by ensuring dual connectivity is only present when actually needed for the current data session, rather than being forcibly maintained for all SIMs.
