Abstract: The method includes receiving a plurality of calls from users of the communication network, the plurality of calls having a non-homogenous arrival rate that is defined by first arrival rate information, transforming the first arrival rate information into second arrival rate information, the second arrival rate information having a homogenous arrival rate, and detecting at least one first anomaly of the received plurality of calls using the second arrival rate information. A network node may be configured to perform this method.
