    Abstract: Measures for processing data in a telecommunications network. At a cache, a subscriber configuration data request requesting subscriber configuration data for a subscriber device is received from a network node in a cluster of network nodes. In response to receipt of the subscriber configuration data request, it is determined that a shared cache store does not contain subscriber configuration data for the subscriber device. In response to the determination, subscriber configuration data for the subscriber device is retrieved from a subscriber configuration network node. The subscriber configuration data for the subscriber device retrieved from the subscriber configuration network node is transmitted to the network node.

    Abstract: Measures, including methods, apparatuses and non-transitory computer-readable storage media, associated with network orchestration. A model of a physical resources part of a network and a model of a virtualised resources part of the network are obtained. The physical/virtualised resources part of the network includes a plurality of physical resources/at least one virtualised network function and represents dependencies between different physical/virtualised resources in the physical/virtualised resources part of the network. At least one optimisation operation is performed using the models of the physical and virtualised resources parts of the network to identify an optimised mapping of the at least one virtualised network function onto at least one of the plurality of physical resources. The at least one virtualised network function is instantiated on the at least one of the plurality of physical resources based on the identified optimised mapping.

    Abstract: Measures (for example methods, systems and non-transitory computer-readable storage media) to process data in an IMS network, including an HSS, an I-CSCF and an S-CSCF. The I-CSCF transmits a request message identifying a user of the IMS network to the HSS. The I-CSCF receives an answer message from the HSS. The answer message comprises an indication either that the user is assigned and not registered to the S-CSCF, or that the user is registered with the S-CSCF. The I-CSCF performs a predetermined action in response to the answer message indicating that the user is assigned to the S-CSCF.

    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: 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 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.
