Abstract: Embodiments of the present invention provide methods for providing a non-registering endpoint with non-registration services (such as the ability to make a call) in an IMS network without requiring the non-registering endpoint to register. A request for a non-registration service is received and processed by an entity in the IMS network that is configured to handle such requests. The entity requires information about the non-registering endpoint itself before it can process the request. Since the non-registering endpoint is part of the network, a Home Subscriber Server (HSS) knows some information about the non-registering endpoint, but can only provide this information to the entity if the non-registering endpoint is registered or being registered by the entity. Consequently, in embodiments, the entity makes it look like the non-registering endpoint is registering, in order for the entity to obtain the information from the HSS.

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.
