Abstract: Measures, including methods, systems and computer-readable storage mediums, for use in operating a network node in a network. Signalling information for an in-progress communication session dialog is processed according to a stateless operating mode. The processing according to the stateless operating mode includes storing communication session dialog state data associated with the communication session dialog. An operating mode change trigger is detected. In response to the detection, the stored communication session dialog state data associated with the communication session dialog is retrieved. Signalling information for the in-progress communication session dialog is processed according to a state-full operating mode. The processing according to the state-full operating mode is carried out at least in part on the basis of the retrieved communication session dialog state data associated with the communication session dialog.

Abstract: Measures for detecting unusual communication session events in a telecommunications network. A Markov model for events occurring in communication sessions conducted in the network is maintained. The maintaining includes assigning a probability of occurrence metric to a plurality of event sequences in the conducted communication sessions. In response to a given sequence of communication session events being assigned a probability of occurrence metric which exceeds a predetermined threshold, an unusual communication session event alert in association with the given sequence is triggered.
