Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual SIM mobile phones face challenges in optimally selecting the most beneficial SIM for connections due to complexity in parameters such as time, location, and application requirements, often resulting in sub-optimal selections when relevant parameter values are unavailable.
Innovation Solution
A method and system that obtain current values of various parameters for each SIM, including geographical location, system-specific, and user-specific parameters, from both the device and a remote server, to automatically select the most favorable SIM for utilization based on dynamic and weighted averages, ensuring optimal connection efficiency and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual SIM selection is used, then device complexity is reduced, but selection optimality deteriorates
Solution Approach 1:
The system automatically selects the optimal SIM card based on collected parameters and predefined selection criteria, eliminating the need for manual user intervention. The selection process is performed autonomously by the device's selection mechanism using criteria such as signal strength, network type, and user-defined preferences.
Solution Approach 2:
The system continuously collects feedback parameters including signal strength, network type, and connection status to dynamically adjust SIM selection decisions. This feedback loop enables the system to adapt to changing network conditions and make optimal real-time selections.
2Loss of time
If automated SIM selection based on local parameters is used, then selection speed is improved, but selection accuracy deteriorates in unfamiliar locations
Solution Approach 1:
The system pre-configures multiple selection criteria and weights before actual SIM selection is needed. Users can pre-set preferences for network types, signal strength thresholds, and priority rules, so that when selection is required, the system can quickly execute predefined logic without delay.
Solution Approach 2:
The system introduces a cloud-based service as an intermediary that provides network information and selection recommendations for unfamiliar locations. When the device is in an unknown area, it queries the cloud service for historical data and recommendations, bridging the gap between local processing speed and external knowledge accuracy.
3Reliability
If multiple parameters are collected for SIM selection, then selection accuracy is improved, but device complexity and data processing requirements worsen
Solution Approach 1:
The system segments the parameter collection process into distinct categories: local device parameters (signal strength, battery level), network parameters (network type, operator), and user preference parameters. Each category is collected and processed separately, then combined using predefined weights and criteria, simplifying the overall complexity.
Solution Approach 2:
The system dynamically adjusts the number and type of parameters collected based on current conditions. In familiar locations, fewer parameters are collected for faster selection, while in unfamiliar locations, additional parameters are gathered from cloud services to improve accuracy. The weightings of parameters are also dynamically adjusted based on user preferences and network conditions.
