Mobile Terminal Wi-Fi Connection Prioritization via Location Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile user terminals face high power consumption and inefficiency in selecting Wi-Fi connections for data communication, especially when departing from predicted routes or lacking nearby Wi-Fi spots, as existing methods fail to effectively prioritize Wi-Fi connections in areas providing Wi-Fi services.
Innovation Solution
A mobile user terminal system that stores location information associated with Wi-Fi access IDs, detects the user's location, and prioritizes Wi-Fi connections by selecting the appropriate ID for data communication through Wi-Fi when the location matches a stored Wi-Fi access point, thereby reducing power consumption and enhancing connection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal predicts its route by acquiring GPS signals at a constant cycle, then it can identify Wi-Fi spots on the predicted route, but it consumes extra power and fails to select Wi-Fi connection when departing from the predicted route
Solution Approach 1:
The system pre-acquires and stores location information about Wi-Fi spots in advance, creating a database of available Wi-Fi locations. This preliminary action eliminates the need for continuous real-time detection, reducing power consumption while ensuring reliable Wi-Fi connection selection when the terminal is at stored locations
Solution Approach 2:
Instead of continuously acquiring fresh GPS signals and performing real-time route prediction, the system uses stored copies of location information from previous acquisitions. This copying approach maintains connection reliability while dramatically reducing the computational and energetic overhead of continuous real-time processing
2Reliability
If the mobile terminal continuously performs route prediction and Wi-Fi spot detection processes, then it can maintain accurate connection selection, but it increases power consumption significantly
Solution Approach 1:
The system performs Wi-Fi spot detection and location information acquisition periodically or at specific trigger events rather than continuously. By using periodic action, the terminal maintains adequate connection selection accuracy while avoiding the excessive power consumption associated with continuous monitoring and processing
3Productivity
If the mobile terminal uses GPS-based route prediction to identify Wi-Fi spots, then it can proactively connect to Wi-Fi, but it fails to respond when actually located in Wi-Fi areas not on the predicted route
Solution Approach 1:
The system uses location information for multiple purposes: both for predictive route planning and for reactive location-based connection selection. By making the location matching mechanism universal and applicable in both predictive and reactive scenarios, the system achieves high productivity through proactive connection while simultaneously gaining adaptability to handle unexpected locations where Wi-Fi spots exist
