One-Way Push Notification Display Update Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display update technologies on terminal devices, such as smartphones, require multiple communications and can fail if one communication attempt fails, leading to delayed updates and increased user operation, especially in unstable wireless communication environments.
Innovation Solution
A display control method that receives a push notification via one-way communication, extracts data based on identification information, and updates the display content once, reducing the number of necessary communications and ensuring immediate update without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication steps are used for content update, then the update can be completed reliably, but the update time increases and user operation is required
Solution Approach 1:
The server sends a push notification in advance to inform the terminal of available content updates. The terminal device proactively checks for updates based on this notification and automatically downloads updated content without waiting for user initiation, thus reducing update time while maintaining reliability through pre-arranged communication protocols
Solution Approach 2:
The system implements a feedback mechanism where the terminal device automatically reports its update status back to the server. The server monitors communication success and can trigger retry mechanisms or alternative delivery methods if initial updates fail, ensuring reliable completion without requiring additional user operations
2Reliability
If communication retry mechanism is implemented, then update reliability improves, but the total communication time increases
Solution Approach 1:
The system employs periodic communication attempts with predetermined intervals rather than continuous retry. The terminal device schedules update checks at regular intervals, and the server sends periodic notifications, allowing the system to balance reliability with time efficiency by not indefinitely extending communication duration
Solution Approach 2:
The communication retry mechanism dynamically adjusts parameters such as retry intervals and timeout durations based on network conditions and update priority. High-priority updates may trigger immediate retries with shorter intervals, while lower-priority updates use extended intervals, optimizing the balance between reliability and communication duration
3Ease of operation
If automatic display update is implemented, then user operation is reduced, but the processing load on server increases
Solution Approach 1:
The system extracts and separates critical update information into push notifications sent to terminals, while the terminal device autonomously handles the complex tasks of checking update availability, downloading content, and refreshing displays. This distribution of processing load reduces server energy consumption while maintaining automatic update functionality
Solution Approach 2:
The terminal device is designed to autonomously manage the update process including receiving notifications, determining update necessity, downloading content, and automatically refreshing the display without user intervention. The server's role is minimized to sending notifications and providing update content when requested, significantly reducing its processing load

AI summary
A non-transitory computer-readable recording medium stores a display control program that causes a computer to execute a process. The process includes, receiving a notification from a terminal in one-way communication, when identification information included in the received notification is detected, extracting data included in the notification, and updating display contents of a display device from first display contents to second display contents based on the extracted data.
