Communication Device Channel Switching via Delay Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face delays when multiple devices share the same communication channel, leading to unnecessary channel switching even when the current channel is sufficient, as they continuously switch to channels with higher throughput without assessing the actual communication state.
Innovation Solution
A communication device uses an echo request command to ascertain communication delay time and determines the communication state based on threshold values, switching channels only when the state is unsatisfactory, thereby preventing fruitless channel switching among available channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication channel is switched continuously to channel with higher throughput, then communication efficiency is improved, but unnecessary channel switching occurs even when current channel is sufficient
Solution Approach 1:
The communication device uses echo request commands to continuously monitor communication delay time and compares it against threshold values to determine whether channel switching is necessary. This feedback mechanism prevents unnecessary switching by only acting when actual communication quality deteriorates below acceptable levels.
Solution Approach 2:
The system performs self-assessment of communication quality using echo request commands sent to itself or reference devices. This self-service approach allows the device to autonomously determine when channel switching is needed without external intervention, reducing unnecessary switching while maintaining communication efficiency.
2Productivity
If multiple communication devices share the same communication channel, then channel utilization is improved, but communication delay time increases
Solution Approach 1:
The system continuously monitors communication delay time through echo request commands and uses this feedback to determine when to switch channels. This allows the system to tolerate channel sharing until delay exceeds acceptable thresholds, optimizing the balance between channel utilization and communication speed.
Solution Approach 2:
The system changes the operational parameter (communication channel) only when the monitored parameter (delay time) exceeds a threshold. This dynamic parameter adjustment optimizes channel utilization by allowing multiple devices to share channels during low-traffic periods while switching to dedicated channels when delay becomes problematic.
3Productivity
If channel switching is performed based on throughput calculation, then communication efficiency is improved, but fruitless switching occurs when current channel state is satisfactory
Solution Approach 1:
The system uses echo request commands to obtain real-time feedback on communication delay and compares this against threshold values. This feedback-driven approach ensures channel switching occurs only when communication quality actually deteriorates, maintaining stability while preserving efficiency.
Solution Approach 2:
The patent replaces the mechanical approach of continuous channel switching based on throughput calculations with a threshold-based decision system using echo request commands. This substitution reduces fruitless switching by introducing a stability threshold that must be exceeded before channel changes occur.

AI summary
There are provided a first communication time ascertaining unit that ascertains with a ping command communication delay time in communication with a smartphone, a communication state determining unit that determines whether a communication state is satisfactory in the communication with the smartphone based on the ascertained communication delay time, and a communication switching unit that switches a communication channel used for the communication with the smartphone, from one communication channel to another communication channel when the communication state in the communication with the smartphone is determined to be unsatisfactory. Therefore, the switching of the communication channel is performed only when it is ascertained that the communication state with the smartphone is unsatisfactory.
