  • Patent number: 9363660
    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.

  • Patent number: 9305126
    Abstract: Aspects of the invention relate to techniques for using retiming to reduce circuit switching activity. Switching activity values at output ports of circuit elements of a circuit design are first computed based on switching activity values at input ports of the circuit elements and scaling factors associated with the circuit elements. Based on the switching activity values at the output ports of the circuit elements, one or more regions of the circuit design for retiming are identified. Retiming location information is then determined for the one or more regions. Finally, the identified one or more regions are then retimed to reduce switching activity based on the retiming location information.

  • Patent number: 9291434
    Abstract: A method of controlling the shape and direction of an explosion may include embedding a plurality of detonators in an explosive, and arranging the detonators in the explosive to produce a shaped explosion of the explosive in a pre-set direction and having a pre-set intensity when triggered in a selected sequence; sensing a direction of an incoming threat relative to a protected region, calculating an intercept vector for the incoming threat, and sending a signal in response thereto by a sensor; receiving information from the sensor pertaining to the intercept vector and determining a sequential firing pattern for the detonators in response to the information from the sensor by a firing sequence calculator connected to trigger the detonators; and activating the firing sequence calculator to trigger the detonators in the sequential firing pattern to generate a counteracting force substantially along the intercept vector.

  • Publication number: 20150215152
    Abstract: Measures for providing timer services in a network including a cluster of nodes responsible for providing timer services to clients. At a given node in the cluster, a request to provide a timer is received from a client. Configuration of a primary replica of the requested timer on a first node in the cluster to pop after a first time has elapsed is initiated. A first timer replication message is transmitted to a second node in the cluster, the first timer replication message indicating that the second node should configure a first backup replica of the requested timer. A second timer replication message is transmitted to a third node in the cluster, the second timer replication message indicating that the third node should configure a second backup replica of the requested timer. Popping of the primary, first backup or second backup timer replicas includes initiating callback of a given client.

  • Patent number: 9031206
    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.

  • Publication number: 20140325603
    Abstract: At a network node separate from a subscriber configuration network node configured to store subscriber configuration data for a plurality of subscriber devices, a request to access configuration data associated with a subscriber stored at the subscriber configuration network node is received. In response to the received access request comprising a private user identity for the subscriber, but not a public user identity for the subscriber, the network node retrieves, from a user identity database configured to store user identity data for identifying subscribers in the network, a public user identity for the subscriber, the retrieval being carried out on the basis of the private user identity for the subscriber comprised in the received access request, and transmits an authorization request to the subscriber configuration network node comprising the public user identity retrieved from the user identity database and the private user identity comprised in the received access request.

  • Publication number: 20140321280
    Abstract: Measures for processing data in a telecommunications network. At a first network node in a cluster of network nodes, a communication session setup request requesting setup of a communication session with a subscriber device in a plurality of subscriber devices is received. In response to receipt of the communication session setup request, registration data relating to the subscriber device is retrieved from a shared registration data store. The communication session setup request is routed according to the retrieved registration data. The retrieved registration data relating to the subscriber device was previously stored in the shared registration data store by a second network node in the cluster of network nodes in relation to a registration procedure conducted for the subscriber device by the second network node, the second network node being a different network node to the first network node in the cluster of network nodes.
