Communication Device Connection Adjuster for Access Point Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in data transmission and reception due to connected states associated with multiple access points, which can lead to suboptimal communication quality and performance.
Innovation Solution
A communication device and system that includes a communicator, a first acquirer for vehicle information, a second acquirer for communication quality information, and a connection adjuster that determines and releases the connected state with an access point based on communication quality and requirements, allowing for efficient data transmission and reception by selecting the most suitable access point for each type of vehicle information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle connects to multiple access points simultaneously, then communication coverage is improved, but communication efficiency and data transmission performance deteriorate
Solution Approach 1:
The system dynamically adjusts the connected state with access points based on communication quality metrics. The connection adjuster continuously monitors communication quality and releases connections to access points that no longer provide optimal performance, making the connection state adaptive rather than static. This resolves the contradiction by maintaining multiple connections when beneficial but releasing them when they hinder efficiency.
Solution Approach 2:
The system changes the connection state parameter (connected or not connected) based on communication quality parameters such as signal strength, data rate, and latency. By monitoring these parameters and adjusting the connection state accordingly, the system optimizes data transmission efficiency while maintaining adequate communication coverage through selective connectivity.
2Adaptability or versatility
If connection state is maintained with all accessible access points, then communication availability is improved, but communication quality and performance deteriorate
Solution Approach 1:
The connection adjuster extracts (releases) connections to specific access points that are determined to be degrading overall communication quality. Instead of maintaining all possible connections, the system selectively removes connections to access points that do not meet quality thresholds, thereby preserving communication availability through remaining connections while improving overall communication quality.
3Reliability
If multiple access points are connected, then network redundancy is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The system dynamically manages connection states to maintain network redundancy only when communication quality justifies it. By continuously monitoring communication quality and adjusting connections in real-time, the system ensures that redundant connections are maintained only when they contribute positively to data transmission efficiency, rather than consistently maintaining all possible redundant connections.

AI summary
According to an aspect, a communication device includes a communicator configured to perform communication with a base station and a plurality of access points having narrower communication ranges than the base station, a first acquirer configured to acquire vehicle information from in-vehicle equipment, a second acquirer configured to acquire information about communication quality for each of the plurality of access points, and a connection adjuster configured to release a connected state associated with a determined access point when the access point whose connected state is released is determined on the basis of the information about the communication quality acquired by the second acquirer if communication with the plurality of access points by the communicator is in the connected state.
