Abstract
Signalling messages may be monitored in a telecommunications network by receiving an indication of a signalling message for a network entity of the telecommunications network, the signalling message comprising a signalling dialog identifier. The signalling dialog identifier of the received signalling message is compared with a list of known signalling dialog identifiers relating to the network entity and the signalling message is categorized based on a result of the step of comparing, for example as suspicious. If a number of signalling messages for a network entity of the telecommunications network categorized as suspicious and having a common additional characteristic is at least a threshold value, an alert may be generated.
