Mobile Data Download Scheduling for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often experience disruptions in online services due to weak wireless connections while in motion, as they may not be able to download necessary content in time, leading to service halts.
Innovation Solution
A method and system that calculate a download scheme based on information about download speeds along a mobile device's route, obtained from historical data or real-time estimations, to optimize data transfer and ensure continuous service by scheduling downloads at optimal times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If data is downloaded in real-time during motion, then service continuity is maintained, but download reliability deteriorates due to weak wireless connections
Solution Approach 1:
The system performs preliminary actions by downloading data in advance during periods of good signal quality (when the mobile device is stationary or in areas with strong coverage). This pre-downloading ensures that data is available before the device enters areas with weak connections, thereby maintaining service continuity without compromising download reliability.
2Speed
If download speed is increased to meet service requirements, then service quality improves, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the download speed based on real-time signal quality conditions. When signal quality is good, the system increases download speed to complete data transfer quickly. When signal quality deteriorates, the system reduces or pauses downloads to conserve energy. This dynamic adaptation allows the system to meet service requirements when possible while minimizing energy consumption during poor connection periods.
3Duration of action of stationary object
If data is pre-downloaded to ensure service availability, then service continuity improves, but storage requirements increase
Solution Approach 1:
The system applies local quality by selectively downloading and storing only the specific data portions that are predicted to be needed in upcoming areas with poor signal coverage. Rather than pre-downloading entire datasets or applications, the system identifies critical data segments based on the predicted route and signal conditions, downloading only those portions to local storage. This ensures service continuity in critical areas while minimizing unnecessary storage consumption.
