Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for vehicles often experience connection interruptions when the communication device is in motion, even if it is connected to a closely-located base station.
Innovation Solution
A communication system that includes a communication device, an access point, and a communication server, which acquires movement information of the device and position information of the access point to determine the connectable time within the access point's communicable range, allowing for controlled connection management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the communication device is connected to a closely-located base station, then the connection speed is improved, but the connection duration is reduced due to movement
Solution Approach 1:
The communication server performs preliminary calculation of the connectable time based on movement information and position information before the actual connection occurs. This advance determination allows the system to prepare connection parameters and predict communication duration, enabling better resource allocation and connection management that extends the actual connection duration.
Solution Approach 2:
The system dynamically adjusts connection parameters based on real-time movement information and position data. By continuously monitoring the communication device's location and velocity, the system can adapt connection settings to maintain optimal communication duration despite the device's motion, resolving the contradiction between connection speed and duration.
2Speed
If the communication device moves quickly, then the mobility is improved, but the connection stability deteriorates
Solution Approach 1:
The system continuously monitors the communication device's position and movement information, using this feedback to dynamically adjust connection parameters. The communication server receives real-time location data and recalculates the connectable time, allowing the system to adapt to changing movement conditions and maintain connection stability even at high speeds.
Solution Approach 2:
The system changes connection parameters such as transmission power, frequency, and modulation schemes based on the calculated connectable time and current movement conditions. By adjusting these parameters dynamically in response to movement speed and position changes, the system maintains connection stability despite rapid device movement.

AI summary
A communication system comprises a communication device; an access point (AP); and a communication server is provided. The communication system performs a method comprising: acquiring first information including movement information of the communication device; acquiring second information including position information of the AP; determining a connectable time corresponding to a length of time the communication device moves within a communicable range of the AP on the basis of the first information and the second information; and controlling a connection between the communication device and the AP on the basis of the connectable time.
