Solution Overview
Problem
Existing communication systems face challenges in efficiently transmitting priority data through relay devices, as they alternately set permitted and prohibited periods for data transmission, leading to delays and inefficiencies in determining the optimal transmission time.
Innovation Solution
A communication device and method that calculate the entire period from data transmission instruction to determination time by acquiring transmission and determination delay times, allowing for precise timing of data transmission instructions to ensure data is transmitted during permitted periods, thereby reducing delays and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the relay device uses fixed permitted and prohibited periods for data transmission, then the transmission schedule is simple to manage, but the determination point in time may fall in prohibited periods causing transmission delays
Solution Approach 1:
The patent makes the permitted period dynamically adjustable by introducing a calculation mechanism that determines the permitted period length based on transmission delay time and determination delay time. This allows the system to adapt the timing parameters to ensure the determination point falls within permitted periods, resolving the contradiction between simple schedule management and transmission timing accuracy
Solution Approach 2:
The patent changes the parameter of permitted period length from a fixed value to a calculated value based on transmission and determination delays. By dynamically adjusting this parameter, the system ensures optimal alignment between determination points and permitted periods, reducing transmission delays while maintaining manageable complexity
2Productivity
If the relay device adjusts the permitted period to accommodate determination points, then transmission efficiency improves, but the calculation and control complexity increases
Solution Approach 1:
The patent applies preliminary action by calculating the permitted period length before data transmission begins. The relay device pre-determines the appropriate permitted period duration based on transmission and determination delays, ensuring that subsequent transmissions can be efficiently scheduled without real-time complex calculations, thus improving productivity while controlling complexity
Solution Approach 2:
The patent implements feedback by using the calculated entire period (transmission delay + determination delay) to adjust and optimize the permitted period configuration. This feedback mechanism allows the system to learn from actual transmission characteristics and refine its timing parameters, improving transmission efficiency while maintaining manageable control complexity through iterative optimization
3Reliability
If the determination point in time falls in prohibited periods, then data must wait for the next permitted period, but this causes increased latency for priority data
Solution Approach 1:
The patent makes the permitted period dynamic and adaptable to actual transmission needs. By calculating the entire period including determination delay, the system can dynamically adjust permitted period timing to ensure priority data determinations occur within permitted periods, eliminating unnecessary waits and reducing latency while maintaining reliable transmission guarantees
Solution Approach 2:
The patent applies preliminary anti-action by proactively configuring the permitted period duration to prevent determination points from falling in prohibited periods. By anticipating potential timing conflicts and pre-adjusting the permitted period parameters, the system avoids the harmful effect of priority data latency before it occurs
Data Source
AI summary
A communication device transmits data to a relay device for transmitting received data. The communication device includes a processing unit that performs processing. The processing unit gives an instruction for data transmission to the relay device, and acquires a transmission delay time from the instruction for data transmission to the transmission of the data. The processing unit acquires a determination delay time from the reception of the data by the relay device to a determination point in time at which whether or not to transmit the received data is determined. The processing unit calculates an entire period from the instruction for data transmission to the determination point in time based on the acquired transmission delay time and determination delay time.
