Radio Frame Analysis System Dynamic Sample Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio frame analysis methods require a large number of samples to achieve accurate results, leading to prolonged analysis times, and struggle to appropriately set the unit time and sample number due to unknown factors like packet length and transmission data content, resulting in wasted time when the network does not match the assumed configuration.
Innovation Solution
A radio frame analysis system that performs clustering processing on frame feature values, calculates distances between clusters, determines reliability based on these distances, and dynamically adjusts the number of samples required to output results, allowing for timely analysis by changing the output timing accordingly.

Engineering Contradiction Analysis
1Measurement precision
If a large number of samples are used to improve estimation accuracy, then the accuracy of analyzing network configuration is improved, but the time required to obtain analysis results increases
Solution Approach 1:
The patent applies dynamics by making the number of samples variable rather than fixed. The analysis unit dynamically adjusts the number of samples based on the actual network configuration state, increasing samples when confidence is low and decreasing them when confidence is high, thereby resolving the contradiction between accuracy and time
Solution Approach 2:
The patent implements feedback through the confidence level calculation mechanism. The analysis unit continuously evaluates the confidence level based on collected sample data and uses this feedback to determine whether to continue collecting samples or to output results, creating a closed-loop system that adapts to the actual analysis needs
2Ease of manufacture
If a fixed unit time is set for data extraction, then the service charge calculation can be simplified, but it takes more time than necessary when the settlement period is longer than required
Solution Approach 1:
The patent makes the extraction period dynamic by allowing it to be adjusted based on the actual network state and analysis requirements. Instead of using a fixed unit time for all cases, the system adapts the extraction period to match the actual time needed to achieve sufficient confidence level, reducing unnecessary waiting time while maintaining calculation simplicity
3Reliability
If error output is delayed until a set number of occurrences is reached, then error recognition reliability is improved, but important errors are not output in time
Solution Approach 1:
The patent applies dynamics by making the error output threshold variable rather than fixed. Instead of waiting for a predetermined number of occurrences, the system dynamically determines the output timing based on the calculated confidence level, allowing important errors to be output immediately when confidence is sufficient while maintaining high reliability for less critical errors
Solution Approach 2:
The patent changes the parameter of error output timing from a fixed count-based threshold to a confidence-level-based threshold. This parameter change allows the system to flexibly adjust when to output errors based on the actual confidence in the detection, resolving the contradiction between reliability and timeliness
