Abstract

A system, method and tool for monitoring switching events in a network with at least two nodes, and a corresponding network, the system, method and tool including means for representing the events originated from different nodes as data in a uniform format, and means for counting the occurrence of events in a node of the network wherein switching events being represented as the same data are counted as the same event.

Claims

1. A system for monitoring switching events in a network with at least two nodes, the system comprising:

means for counting the switching events originated from different nodes as data in a uniform format; and

means for counting occurrence of the switching events in the different nodes of the network as the counting of data, wherein the switching events being represented as the same data are counted as the same event,

wherein the network is a network for communication between a first communication device and a second communication device, the network comprising network elements and a switching center management system, the network elements being linked together and comprising switching centers as the different nodes and the switching centers being arranged, in use, to generate at least one switching event to other network elements during a connecting phase of the communication between the first communication device and the second communication device, and the switching centers including switching event counters for counting the switching events, wherein the switching center management system is being connected to at least one switching center and being arranged to read the values of the switching event counters, wherein the switching center management system is arranged to perform the representation of the switching events in the uniform format to obtain classified switching events by using number analysis of a phone number selected by the first communication device to address the second communication device during the connecting phase,

wherein the classified switching events are divided into at least two of the following categories;

traffic destinations of the phone number selected,

traffic signaling relating to traffic management functions for the communication between the first and second communication device, and

processing load of the at least one mobile switching center, and

wherein the network further comprises a control computer system (CPC) being arranged to carry out the following procedure;

reading the values of the classified switching event counters from the switching center management system (SCMS),

storing the read values of the classified switching event counters in a traffic database file (TDF) in a plurality of memory units of the CPC,

comparing the values of the classified switching event counters in the TDF with respective threshold values stored in a threshold data file (TF) in the plurality of memory units, for determining if the value of a classified switching event counter is within a normal operating range,

storing the value of the classified switching event counter in an output alert file, if the value of the classified switching event counter is out-of-normal-operating-range,

outputting the stored values of classified switching event counters in the output alert file to the SCMS, and

collecting the output alert file by at least one information management system.
