Server Predicts Communication Loss for Moving Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing systems, moving bodies that lose communication with the information management control device cannot receive services from the device during a communication loss, causing inconvenience to users.
Innovation Solution
A system where the server predicts communication loss with moving bodies and transfers execution of part of its processes to the moving body, allowing the moving body to execute necessary processes even when communication is lost by sending required information beforehand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server waits for communication loss to occur before responding, then communication reliability is maintained under normal conditions, but service continuity deteriorates during communication loss
Solution Approach 1:
The server predicts communication loss before it occurs and proactively transfers process execution to the moving body in advance. This preliminary action ensures that the moving body can continue executing processes even when communication is lost, thereby maintaining service continuity and reducing service interruption time.
2Reliability
If the server transfers process execution to the moving body before communication loss, then service continuity improves during communication loss, but device complexity increases
Solution Approach 1:
The server creates a copy of the necessary process information and transfers it to the moving body before communication loss occurs. This copying approach allows the moving body to execute processes independently without requiring complex bidirectional communication protocols or distributed computing infrastructure, thus limiting the increase in system complexity.
3Reliability
If the server continuously monitors communication status, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the server performs communication status checks and process transfers at periodic intervals or based on predicted communication patterns. This periodic approach maintains adequate communication reliability while significantly reducing the energy consumption compared to continuous monitoring.

AI summary
A system includes: a server; and a moving body wherein, the server is configured to communicate with the moving body, predict occurrence of a loss of communication with the moving body, and send information necessary to execute a first process to the moving body when the loss of communication with the moving body is predicted to occur; and the moving body is configured to receive the information from the server, and execute the first process based on the received information.
