Dynamic Communication Buffer Configuration for Uplink Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication buffer management in electronic devices leads to excessive congestion control by the transmission control protocol, resulting in a rapid decrease in uplink transmission rates due to misjudged network congestion states caused by transmission delays associated with the size of the communication buffer.
Innovation Solution
An electronic device is equipped with a communication processor that identifies Radio Link Control (RLC) retransmission time and uplink transmission rate to dynamically configure the size of the communication buffer, thereby reducing transmission delays and optimizing congestion control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the communication buffer size is configured to be relatively large, then the electronic device can store more data and receive more network resources, but the transmission delay increases causing excessive congestion control
Solution Approach 1:
The patent applies dynamics by making the communication buffer size adjustable rather than fixed. The buffer size is dynamically configured based on the RLC retransmission time and uplink transmission rate, allowing the system to adapt buffer capacity to current network conditions and traffic requirements, thus balancing data storage capacity with transmission delay
Solution Approach 2:
The patent changes the parameter of buffer size from a fixed value to a dynamically configurable parameter. By calculating the buffer size using the formula involving RLC retransmission time and uplink transmission rate, the system adjusts buffer capacity parameters to optimize both data storage and transmission timing, preventing excessive congestion control while maintaining adequate storage
2Quantity of substance
If the communication buffer size is configured to be relatively large, then the electronic device can accumulate more data for transmission, but the Round Trip Time measurement becomes inaccurate leading to excessive congestion control
Solution Approach 1:
The patent uses dynamics to adjust buffer size according to current network conditions. By continuously monitoring RLC retransmission time and uplink transmission rate, the system dynamically configures buffer size to ensure that data accumulation does not interfere with accurate RTT measurement, thus preventing misjudgment of network congestion state
Solution Approach 2:
The patent implements feedback by using RLC retransmission time as a key parameter in buffer size calculation. The system continuously monitors network response characteristics and adjusts buffer size accordingly, creating a feedback loop that ensures RTT measurement accuracy while maintaining adequate data accumulation capacity
