1. A method for correlating media streams and signaling sessions of services in a passive monitoring system of a packet-switched network, the method comprising:

  • a) generating at least one correlation key for each direction of a service based on the information of the signaling session of the respective service monitored at the signaling plane probe, wherein the correlation keys for a respective service are generated using a timestamp indicative of the point in time at which the end of the respective signaling session of the respective service has been detected by the signaling plane probe and using information on the direction of the respective service,b) storing, by the signaling plane probe, a signaling session report for each signaling session in a database, wherein each signaling session report comprises the at least two correlation keys generated for the respective directions of the service,c) generating a correlation key for each media stream monitored by the media plane probe, wherein the correlation key is generated using a timestamp indicative of the point in time at which the respective media stream has ended and using information on the media data path of the respective media stream,d) storing, by the media plane probe, a media stream report for each media stream in a database, wherein each media stream report comprises at least the correlation key generated for the respective media, ande) correlating the media streams and the signaling sessions based on the correlation keys comprised within media stream reports and signaling session reports.
