Server Device Managing Emergency Vehicle Communication Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency vehicles face degraded communication quality due to limited availability of high-capacity and high-speed wireless communication systems while en route, especially when near non-emergency vehicles engaging in wireless communication, leading to increased communication traffic and potential information acquisition issues.
Innovation Solution
A server device and in-vehicle devices that acquire the position of emergency vehicles, specify nearby non-emergency vehicles, and transmit communication stop requests to them, prompting occupants to temporarily stop wireless communication to maintain communication quality for emergency vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wireless communication is performed in non-emergency vehicles near the emergency vehicle, then communication traffic increases, but the quality of communication for the emergency vehicle is degraded
Solution Approach 1:
The system applies preliminary anti-action by detecting the approach of an emergency vehicle and proactively requesting non-emergency vehicles to stop wireless communication before the emergency vehicle arrives. The server device receives position information indicating the emergency vehicle is approaching, then transmits a request to the non-emergency vehicle to stop communication, thereby preventing communication quality degradation before it occurs.
Solution Approach 2:
The system extracts the harmful factor (wireless communication from non-emergency vehicles) from the environment surrounding the emergency vehicle. By identifying non-emergency vehicles within a predetermined distance of the emergency vehicle and requesting them to stop communication, the system removes the source of interference to protect the emergency vehicle's communication quality.
2Ease of operation
If non-emergency vehicles continue wireless communication while an emergency vehicle is nearby, then communication convenience is maintained, but emergency response time may be delayed
Solution Approach 1:
The system applies preliminary anti-action by requesting non-emergency vehicles to stop communication in advance when an emergency vehicle is detected approaching. This ensures that communication quality is secured before the emergency vehicle arrives, preventing delays in emergency response while temporarily suspending non-essential communication.
Solution Approach 2:
The system applies dynamics by making the communication state of non-emergency vehicles adjustable based on the presence of emergency vehicles. Non-emergency vehicles normally maintain communication for convenience, but dynamically stop communication when an emergency vehicle is nearby, then resume after the emergency vehicle passes, optimizing both convenience and emergency response needs.

AI summary
A server device configured to communicate with a communication device mounted in a vehicle, the server device includes a controller configured to execute acquiring a position of an emergency vehicle, specifying a non-emergency vehicle at a predetermined distance from the position of the emergency vehicle, and transmitting, to a communication device mounted in the non-emergency vehicle, a request as information requiring the non-emergency vehicle to stop use of wireless communication.
