Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling transmission rates require high-frequency and high-accuracy clocks, leading to a significant computation load for designating transmission start times and managing transmission stoppages, which is inefficient.
Innovation Solution
A communication control apparatus that generates packets based on coded data, reception state information, and communication line capacity, using a low-frequency system clock to control the transmission rate without calculating stoppage timing, thereby reducing computational load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If transmission rate control is implemented by calculating transmission stoppage timing and resumption timing, then transmission rate control precision is improved, but computation load increases
Solution Approach 1:
The patent extracts the complex timing calculation logic (stoppage timing and resumption timing) from the transmission rate control system and replaces it with a simpler packet counting mechanism. The calculating unit now only needs to determine the number of packets to transmit based on buffer state information, rather than calculating precise timing parameters, thereby reducing computation load while maintaining control precision.
Solution Approach 2:
The patent changes the control parameter from time-based (transmission stoppage timing and resumption timing) to packet-count-based (number of packets to transmit). This parameter transformation simplifies the control logic and reduces computational requirements while achieving the same transmission rate control objective.
2Measurement precision
If high-frequency and high-accuracy clock is used for controlling transmission intervals, then transmission rate control precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces the expensive high-frequency and high-accuracy clock system with a simpler, lower-cost clock that operates at standard frequencies. The precision previously achieved through high-frequency timing is now obtained through packet counting logic, eliminating the need for costly timing hardware while maintaining control accuracy.
3Adaptability or versatility
If transmission stoppage period is controlled to adjust transmission rate, then transmission rate adaptability is improved, but computation load increases
Solution Approach 1:
The patent applies different control strategies to different aspects of transmission rate control: the adapting aspect (determining how many packets to send) uses buffer state information for local adaptation, while the execution aspect (actual packet transmission) uses simple packet counting. This localized approach maintains adaptability without requiring complex global timing calculations.
