A method for detecting anomalies in one or more network performance metrics stream for one or more monitored object comprising using a discrete window on the stream to extract a motif from said stream for a first of said network performance metric for a first of said monitored object. Maintaining an abnormal and a normal cluster center of historical time series for said first network performance metric for said first monitored object. Classifying said motif based on a distance between said new time series and said abnormal and said normal cluster center. Determining whether an anomaly for said motif occurred based on said distance and a predetermined decision boundary.

Network performance metrics anomaly detection

A system, method, and computer program product are provided for managing a shared quota for a plurality of network subscribers in a consumer telecommunications network. In use, a first usage quota reservation out of a shared quota is allocated to at least one first subscriber among a plurality of network subscribers. Further, it is determined that at least a portion of the shared quota is available. Additionally, a progressively smaller at least one second usage quota reservation out of the at least a portion of the shared quota is recursively allocated to the at least one first subscriber among the plurality of network subscribers, the smaller at least one second usage quota reservation being smaller than the first usage quota reservation out of the shared quota.

System, method, and computer program for managing a shared quota for a plurality of network subscribers in a consumer telecommunications network

A system, method, and computer program product are provided for utilizing an alternative Policy and Charging Rules Function (PCRF) node in a consumer telecommunications system. In use, an Sy session for a subscriber of a consumer telecommunications network is established, the Sy session being between a first PCRF node and an Online Charging System (OCS) node of the consumer telecommunications network. Additionally, the first PCRF node specifies an alternative PCRF node. Further, information associated with the Sy session is maintained at the alternative PCRF node. In addition, the first PCRF node is monitored and it is determined whether the first PCRF node is responsive to communication therewith. Responsive to determining that first PCRF node is not responsive to communication therewith, the Sy session is continued between the OCS node and the alternative PCRF node.

System, method, and computer program for utilizing an alternative policy and charging rules function (PCRF) node in a consumer telecommunications network

A system, method, and computer program product are provided for managing a shared quota for a plurality of network subscribers in a consumer telecommunications network. In use, an Sy interface session is established for a subscriber of a consumer telecommunications network, the Sy interface session being between a Policy and Charging Rules Function (PCRF) node and an Online Charging System (OCS) node of the consumer telecommunications network. Further, it is determined whether the subscriber is associated with any multi-subscriber shared usage counters on the consumer telecommunications network. Responsive to determining that the subscriber is associated with at least one multi-subscriber shared usage counter on the consumer telecommunications network, a reference to the at least one multi-subscriber shared usage counter is provided to the PCRF node by the OCS node. Additionally, the OCS node monitors the at least one multi-subscriber shared usage counter. Responsive to determining that a status of the at least one multi-subscriber shared usage counter has changed, a single Spending Status Notification Request (SNR) message is sent to the PCRF node, the single SNR message notifying the PCRF node that the status of the at least one multi-subscriber shared usage counter has changed. Responsive to the PCRF node receiving the single SNR message notifying the PCRF node that the status of the at least one multi-subscriber shared usage counter has changed, the PCRF node determines which open sessions on the consumer telecommunications network are associated with the at least one multi-subscriber shared usage counter. Furthermore, one or more policy changes to the open sessions are executed in accordance with the change to the at least one multi-subscriber shared usage counter.
