Anomaly detector, anomaly detection network, method for detecting an abnormal activity, model determination unit, system, and method for determining an anomaly detection model

摘要

An anomaly detector (100) for detecting an abnormal activity in a telecommunications network. The anomaly detector (100) includes a receiver unit (102) configured to receive a plurality of network measurements (nm) in relation to the telecommunications network; a model-based mapping unit (104) configured to map the received plurality of network measurements (nm) via a machine-trained anomaly detection model (106) to an anomaly indicator (ai); and an output unit (108) configured to provide the anomaly indicator (ai), which indicates the abnormal activity in the telecommunications network.
