Summary:This document discloses a solution for detecting and mitigating anomalies such as signalling storms in a radio access network of a wireless communication system. According to an aspect, there is disclosed a method comprising: receiving, in a first local traffic analysis module, configuration parameters from a second local traffic analysis module or from a central traffic analysis module connected to a plurality of local traffic analysis modules; monitoring, by a first traffic analysis module by using the received configuration parameters, traffic in a radio access network of a wireless communication system; detecting, in the monitored traffic on the basis of the configuration parameters, an anomaly causing a control plane signalling load; and in response to said detecting, taking an action to mitigate the anomaly and reporting information on the anomaly to the central traffic analysis module.
