    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.

    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.
