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.

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.
