Abstract: A system for performing underwater earthworks, the system including a power pack situated outside the water, at least one submersible operating unit for performing underwater earthworks, wherein the operating unit is connected with the power pack through power supply means, and a control unit connected via data communication means with the power pack and the operating unit and with instrumentation indicating location and depth of the operating unit.

Abstract: A computerized method, system, and computer program product thereof determines a service topology of a telecommunication network respective of one or more user devices. Information related to a service, provided to the user device over a telecommunication network, is received. The service may be providing connectivity required for a voice call, a data session, short message service (SMS) or the like. Information related to at least a network element of the telecommunication network is collected, the network element having supplied the service. A telecommunication network topology for the service is determined related to the information. A failure notification is received through the telecommunication network. An impact on the service is determined, related to the telecommunication network topology and the failure notification. The impact may be full or partial loss of service. A service notification may be sent related to the determined impact, for example to a fault management system.

Abstract: A performance indicator monitoring system (PIMS) receives a plurality of operational measurements (OMs) for each performance indicator (PI), which may be stored on a first storage. A rate of access by a monitoring system is determined for the PI. The rate may be determined, for example, related to a counter of the PI. An enriched dataset related to a subset of the plurality of OMs is generated, upon determination that the selected PI rate of use is higher than a primary threshold value. The generated enriched dataset may be stored in a second storage. In some embodiments, a component of the PIMS, such as a processing unit, is determined. A usage level of the component is then determined, and the enriched dataset is generated if the usage level of the component is below a secondary threshold.

Abstract: A computerized method, system, and computer program product can allow for processing by a processor data records (xDRs). The method can include receiving by the processor xDRs, each xDR including a vector of unique data fields, the xDRs forming together a stream. The stream can be stored by the processor in a memory of a general purpose graphic processor unit (GPGPU). An index vector of xDRs can be created by the processor, wherein each xDR is assigned a unique index identifier, and stored by the processor in a memory of the GPGPU. The index vector of xDRs is sorted with respect to at least a key of at least a unique data element selected. The sorted index vector can be stored in the memory of the GPGPU. A selection of at least the unique data field can be performed and aggregation of the stream performed with respect to the selection.

Abstract: A system and method for identification and handling of a flood of alarms in a telecommunications system. A flood event occurs when a plurality of alarms in a queue of an alarm management system exceeds a threshold. The threshold may be a static, dynamic or adaptive threshold. A classification is determined for each flood event and preventive measures are determined. A plurality of floods having identical or different classifications may be identified respective of the plurality of alarms. A classification may be related, for example, to a network element (NE), element manager (EM), sync event, user actions, external application or rules. Preventive measures may be, for example, resetting a NE or EM or diverting alarms from the queue into another memory portion. The threshold may be determined respective of the total number of alarms in queue, the rate of alarms received and the rate of processing the alarms.
