Radio Frame Transmission Rate Estimation via Sequence Number Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio frame capture and analysis techniques fail to accurately account for capture loss, leading to incomplete analysis of radio communication failures, particularly in environments with changing radio wave conditions, where increased communication traffic from other terminals can cause throughput deterioration in the primary communication terminal.
Innovation Solution
An estimation apparatus and method that acquires captured radio frames and estimates the transmission rate of non-captured frames based on features such as capture rate, retransmission ratio, and average transmission rate of captured frames, using relational expressions to calculate the transmission rate of missed frames and their bandwidth occupancy.

Engineering Contradiction Analysis
1Measurement precision
If radio frames are captured using a monitor device, then radio communication analysis can be performed, but capture loss occurs when the communication traffic exceeds the device's capture capability
Solution Approach 1:
The patent introduces sequence numbers as an intermediary mechanism to track and identify captured and non-captured radio frames. By analyzing the continuity of sequence numbers in captured frames, the system can detect gaps that indicate capture loss without requiring the monitor device to capture every single frame, thus resolving the contradiction between capture capability and traffic volume
Solution Approach 2:
The system implements feedback by continuously monitoring sequence numbers of captured radio frames and using this information to detect capture loss. The detection of missing sequence numbers provides feedback about the capture status, enabling the system to identify when capture loss has occurred and analyze its impact on radio communication failure diagnosis
2Productivity
If only captured radio frame information is analyzed, then analysis can be performed with available data, but the cause of radio failure cannot be accurately identified due to capture loss
Solution Approach 1:
Sequence numbers serve as an intermediary that bridges the gap between captured and non-captured frames. By analyzing the pattern of missing sequence numbers, the system can infer information about non-captured frames without actually capturing them, thus maintaining analysis speed while improving failure cause identification accuracy
Solution Approach 2:
The patent converts the harmful effect of capture loss into a beneficial diagnostic tool. Instead of treating missing frames as a problem to be eliminated, the system uses the pattern of missing sequence numbers as evidence to identify capture loss and determine its impact on radio communication failures, thereby turning an obstacle into a source of diagnostic information
3Device complexity
If the transmission rate of non-captured frames is unknown, then analysis can proceed with captured data only, but the bandwidth occupancy of non-captured frames cannot be determined
Solution Approach 1:
The patent uses sequence number analysis as an intermediary method to estimate the transmission rate of non-captured frames. By examining the temporal pattern of missing sequence numbers and comparing with captured frames, the system can infer the transmission rate and bandwidth occupancy without direct measurement, thus determining bandwidth information without adding significant analysis complexity
Solution Approach 2:
The system creates a virtual representation or copy of the non-captured frames' characteristics by analyzing the pattern of missing sequence numbers. This virtual copy contains estimated transmission rate and bandwidth occupancy information, allowing the system to work with complete information (captured + non-captured) without actually capturing every frame, thus maintaining low complexity while recovering lost information

AI summary
In order to provide an estimation apparatus that estimates a transmission rate of a radio frame missed being captured, an estimation apparatus includes an acquisition section and an estimation section. The acquisition section acquires a captured radio frame captured by a capture apparatus. The estimation section estimates, based on a feature related to the captured radio frame, a transmission rate of a non-captured radio frame that is not captured by the capture apparatus. The estimation section may calculate a capture rate by dividing a number of the captured radio frames by a total number of radio frames, the total number of the radio frames being obtained by adding the number of the captured radio frames and a number of the non-captured radio frames estimated from the captured radio frames, and estimate the transmission rate of the non-captured radio frame higher, as the capture rate is lower.
