Title:
ADAPTIVE FILTERING BASED NETWORK ANOMALY DETECTION
Document Type and Number:
WIPO Patent Application WO/2017/016492
Kind Code:
A1
Abstract:
A method includes performing, via a controller, adaptive filtering on a network quality indicator to predict future values of the network quality indicator, calculating, via the controller, residues between the predicted future values and measured values of the network quality indicator, analyzing, via the controller, the residues over at least one selected frequency band to determine if a threshold has been exceeded for the at least one selected frequency band, and detecting, via the controller, an anomaly event of the network in a frequency band in which a threshold has been exceeded using the residues and measured values of the network quality indicator.
