Abstract:
Method for net wide call trace of at least one call within a telecommunication network with various interfaces and protocol stacks by using a central call trace server (CS) and local intelligent call trace intelligent agents (IA) between the switching points (SP) of the telecommunication network, said central call trace server being connected with all of said local intelligent call trace intelligent agents (IA), with the following steps:activating the intelligent agents (IA) by the central server (CS) together with a message comprising a trigger number (TN) to be call traced; comparing the trigger number (TN) with the contents of the call establish messages of the calls running on a signaling channel (SC) by the intelligent agents (IA) and sending an establish message to the central server (CS) by those intelligent agents (IA) which have matched with the trigger number together with additional information (RL) about a detected connection between two switching points (SP) as well as at least an identification number of the intelligent agent (IA); sorting the messages and information (RL) by the central server (CS) sent by the intelligent agents (IA), removing redundant information and allocating the information to a respective section belonging to two switching points (SP) being connected together. tracing all signaling data belonging to the detected call by the intelligent agents (IA) being involved in view of the matching of the trigger (TN); detecting the call terminating by at least one of said intelligent agents (IA) and sending a call termination message to the central server (CS), forwarding the message concerning the call termination to all the other intelligent agents (IA) being involved in the call trace; and transmitting the recorded data to the central server (CS) and displaying the data by the central server (CS) dependent on the different transmission layers in the telecommunication network.
