Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle communicators face the challenge of concentrated load on one wireless channel when using multiple channels simultaneously, which affects the efficiency of wireless communication in Intelligent Transport Systems.
Innovation Solution
A communication device that utilizes multiple wireless channels concurrently by employing a control channel for safety information and service channels for comfort and convenience information, with a multi-hop packet system that dynamically selects and designates forwarding channels to distribute load across channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless channels are used simultaneously for communication, then communication capacity and versatility are improved, but load concentration on individual channels increases
Solution Approach 1:
The patent implements dynamic channel selection and load distribution mechanisms where the communication device adapts its channel usage based on real-time channel conditions, traffic patterns, and load metrics. The system dynamically adjusts which channels are used for different types of communication (safety vs. comfort/convenience) and redistributes traffic to balance channel loads, preventing any single channel from becoming overloaded while maintaining versatile multi-channel operation.
Solution Approach 2:
The patent assigns different communication functions to different wireless channels based on their characteristics and requirements. Safety-related communications are designated for specific channels with higher reliability requirements, while comfort and convenience communications use other channels. This local differentiation of channel quality and purpose allows the system to maintain high versatility across multiple channels while ensuring that critical communications are not affected by load concentration on any single channel.
2Device complexity
If one wireless channel is used for all communication, then channel management is simplified, but communication capacity and efficiency are reduced
Solution Approach 1:
The patent segments wireless communication into distinct categories (safety communications and comfort/convenience communications) and assigns them to different wireless channels. This segmentation allows the system to improve overall communication efficiency by utilizing multiple channels simultaneously for different traffic types, while the channel management complexity is controlled through automated classification and routing mechanisms that determine which segment of communication uses which channel based on predefined criteria.

AI summary
Provided are a communication device, a communication method, and a recording medium that can reduce concentration of a load on one of wireless channels. A communication device that uses wireless channels includes: acceptance means for accepting, from a different communication device and through one of the wireless channels, channel information that indicates wireless channels that can be used by the different communication device; control means for selecting, as a wireless forwarding channel for first information, a wireless channel, which is different from a wireless transmission channel for transmitting the first information, from among the wireless channels that are indicated by the channel information, and for adding second information indicating the wireless forwarding channel to the first information; and transmission means for transmitting the first information provided with the second information by using the wireless transmission channel.
