Dynamic Data Shunting via Buffer Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, existing data shunting methods struggle to determine the optimal data rate for shunting to a shunting node device, leading to data packet congestion or resource wastage due to mismatched transmission rates between the shunting node and the target UE.
Innovation Solution
A data shunting method that involves acquiring the number of to-be-transmitted data packets cached in the shunting node device through report messages and adjusting the transmission based on threshold values to ensure optimal buffer utilization and prevent congestion, using report instructions to manage data packet reporting and cache status reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the shunting rate is increased to improve data transmission efficiency, then the data transmission speed improves, but data packet congestion occurs in the shunting node device causing increased delays and packet loss
Solution Approach 1:
The patent implements a feedback mechanism where the shunting node device reports its buffer status (number of cached to-be-transmitted data packets) to the data transmission device. Based on this feedback, the data transmission device dynamically adjusts the shunting rate by comparing the reported buffer status against threshold values, thereby preventing congestion while maximizing transmission efficiency.
Solution Approach 2:
The shunting rate is made dynamic rather than fixed. The data transmission device continuously monitors the buffer status of the shunting node device and adjusts the shunting rate in real-time based on the current buffer conditions, allowing the system to adapt to changing network conditions and prevent congestion.
2Reliability
If the shunting rate is decreased to avoid congestion in the shunting node device, then data packet delays and losses are reduced, but resources in the shunting node device are wasted
Solution Approach 1:
The shunting node device provides feedback about its buffer status to the data transmission device. This feedback enables the transmission device to accurately assess the current resource availability at the shunting node and adjust the shunting rate accordingly, ensuring resources are fully utilized without causing congestion.
Solution Approach 2:
The system changes the shunting rate parameter dynamically based on the buffer status parameter reported by the shunting node device. By adjusting this parameter in response to real-time conditions, the system optimizes both resource utilization and reliability.
3Device complexity
If the data transmission device transmits data at a fixed rate without monitoring shunting node buffer status, then the transmission process is simple, but the system cannot adapt to varying network conditions causing either congestion or resource waste
Solution Approach 1:
A feedback mechanism is introduced where the shunting node device reports its buffer status to the transmission device. This feedback enables adaptive control of the shunting rate without significantly increasing system complexity, as the control logic is concentrated in the transmission device.
Solution Approach 2:
The shunting node device autonomously monitors its own buffer status and reports it when thresholds are reached, eliminating the need for continuous polling by the transmission device. This self-service approach simplifies the overall control mechanism while maintaining high efficiency.
