The invention relates to a method for improving monitoring measures in telecommunication and data networks (typically IP-based networks with an Internet and Intranet connection). Improved technological developments nowadays result in packet-oriented mobile radio networks (GSM/GPRS, UMTS etc.) and an increased number of Internet connections via a fixed network offering cost-optimised Internet access by means of flat rates or always on packages .Since an insufficient number of public Internet addresses is available, said addresses must be multiplied by means of port sharing (PAT), timesharing (NAT), applications-sharing (Proxy) or other methods. When an address is transformed at the boundary of the network (AN) the external addressing parameters are not, however, available inside the network-internal communication protocols, whereby monitoring measures can only be carried out in a limited manner via the network boundaries. According to the invention, this problem is solved by incorporating the converting devices into the monitoring measure by means of selectively used technical creations and the dynamic addressing parameters are stored along with the added time and date, thereby making it possible to request information in a current/posterior mode beyond network boundaries (Internet etc.) in accordance with the Law. The inventive solution is economical and does not hinder performance. |
