Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a multi-detection-window joint detection and analysis method for a mobile communication network, which is used for carrying out joint detection on multiple detection windows, establishing automatic adaptive association through the correlation strength relation between the detection windows, and triggering alarm reminding or quickly diagnosing the reason of an abnormal event before the abnormal event occurs. The technical scheme has the characteristics of considering the convenience of programming at the beginning, being convenient and rapid to deploy, greatly improving the precision and efficiency of system analysis, having wide application range and the like.
As shown in fig. 2, a schematic diagram of a method for joint detection and analysis of multiple detection windows in a mobile communication network according to an embodiment of the present invention mainly includes:
and A, analyzing a test Log file and carding a structure.
And A1, completely analyzing the data in the field test Log file to obtain two parts of signaling data and measurement data.
In the embodiment of the invention, the longitude and latitude of the signaling data are correspondingly synchronized, and the measurement data are correspondingly synchronized with the time.
Step A2, logically separating the data of different periods from the random sampling, and dividing the data into signaling data and measurement data according to different attributes: abnormal events, strong correlation factors and weak correlation factors.
In the embodiment of the invention, strong and weak related factors exist in the measured data, and the signaling data is used for judging whether an abnormal event exists.
As shown in fig. 2-3, the introduction of wireless signal interruption is often accompanied by the transition of the weakly correlated feature to the strongly correlated feature until an abnormal event occurs; namely, the weak correlation factor (also called indirect reason) is converted into a strong correlation factor with a certain probability after lasting for a certain time, and the strong correlation factor (also called direct reason) is converted into an abnormal event with a certain probability after lasting for a certain time; the detection window is the range interval of strong correlation, weak correlation and abnormal events. The period 480ms in fig. 3 refers to an event interval of sending periodic measurement reports of the GSMR wireless system, and the system confirms that a wireless channel is available through uninterrupted measurement.
Illustratively, the weak correlation factor includes the magnitude of the coverage level, the strong correlation factor includes the magnitude of the signal-to-noise ratio, and the like, the reference index of the abnormal event may be the magnitude of the bit error rate, and the abnormal event that may be caused mainly includes: access failure, too large time delay of channel allocation, call reestablishment, rescue switching, switching failure, channel coding degradation, abnormal release and release time delay.
Step A3, after dividing the measurement data according to different attributes, dividing the respective analysis areas according to the cause-effect relationship (the cause of the strong and weak correlation factors, and the effect of the abnormal event) between the abnormal events and the triggering judgment time length. The trigger judgment duration here can be understood as the duration of the corresponding strong and weak correlation factors, and the analysis area is also the detection range.
In the embodiment of the invention, the abnormal event triggers a timely window to realize the reason diagnosis of the abnormal event (step B); triggering a weak correlation detection window by the weak correlation factors, predicting the weak correlation factors and analyzing the relationship with the strong correlation factors (turning to the step D), and triggering a first-level alarm; the strong correlation factor triggers the strong correlation detection window, the strong correlation factor is predicted, the relation with the weak correlation factor is analyzed (step C is carried out), and meanwhile, a secondary alarm is triggered.
And step B, triggering a timely window by the abnormal event to realize the reason diagnosis of the abnormal event.
And step B1, marking the abnormal events triggering the timely window, and carrying out backtracking analysis to determine the correlation between the strong correlation factors and the weak correlation factors.
And step B2, triggering backtracking analysis of the strong correlation factors, thereby analyzing the relationship between the abnormal event and the strong correlation factors, and correcting the corresponding correlation model according to the analysis result.
And step B3, triggering backtracking analysis of the weak correlation factors, thereby analyzing the relationship between the abnormal event and the weak correlation factors, and correcting the corresponding correlation model according to the analysis result.
And C, triggering a strong correlation detection window by the strong correlation factors, predicting the strong correlation factors and analyzing the relationship between the strong correlation factors and the weak correlation factors.
And step C1, determining whether the current strong correlation factor triggers a strong correlation detection window based on the judgment model, if so, performing statistical analysis on the current strong correlation factor and the correlation model, triggering a secondary alarm, and simultaneously performing the step C2 and the step C3 to perform abnormal event early warning analysis and weak correlation factor backtracking analysis.
And step C2, judging the possibility of abnormal events caused by the current strong correlation factors, and taking the judgment result as the record of the correlation model learning.
And C3, backtracking the deviation of the weak correlation factors and the corresponding thresholds, and deducing the result to be used as a record of the correlation model learning.
In the embodiment of the invention, the correlation model is corrected by combining the recorded result.
And D, triggering a weak correlation detection window by the weak correlation factors, predicting the weak correlation factors and analyzing the relationship between the weak correlation factors and the strong correlation factors.
And D1, determining whether the current weak correlation factor triggers a weak correlation detection window or not based on the judgment model, if so, performing statistical analysis on the current weak correlation factor and the correlation model, triggering a primary alarm, and simultaneously performing the steps D2 and D3 to perform abnormal event early warning analysis and strong correlation factor early warning analysis.
And D2, judging the possibility of abnormal events caused by the current weak correlation factors, and taking the judgment result as the record of the correlation model learning.
And D3, deducing the strong correlation factors and the deviation of the corresponding threshold, and using the deduced result as the record of the correlation model learning.
In the embodiment of the invention, the correlation model is corrected by combining the recorded result. In addition, the step D3 is actually a probabilistic relationship analysis for predicting weak correlation factors (indirect causes) triggering thresholds (i.e. decision models) and predicting abnormal events.
Those skilled in the art can understand that the decision model involved when the strong and weak correlation factors trigger the corresponding detection windows needs to be adjusted according to the surrounding environment of the segment to be analyzed, and the complexity of the surrounding environment and the size of the threshold value in the interference degree image decision model.
The technical scheme of the embodiment of the invention is suitable for various comprehensive process evaluation from quantitative change to qualitative change, early-stage analysis and early warning of abnormal events and reason analysis (such as wireless signals, air temperature, air pressure, humidity, pollution indexes, noise, pavement flatness and the like) of the abnormal events, is used for solving the problem of automatic correlation intelligent analysis of test data and greatly improves the analysis precision and the working efficiency; in particular, the method highlights the early warning from shallow correlation to deep correlation quantitative change until the quality of the abnormal event changes and the event reason of the correlation backtracking analysis after the abnormal event.
