Patent ID: 7277435

Claim:
A method for carrying out monitoring in packet-oriented telecommunication and data networks, comprising the steps of providing a central administration device (ADMF) that manages all subscriber lines (subscribers) which are to be monitored and, regardless of the service-specific use authorization for the individual subscriber line, of the technical opportunity to use the terminals, the geographical sense and further properties which are relevant to network nodes or to subscribers, distributes all existing instances of monitoring, independently of network node, to all packet-data nodes in a telecommunication or data network, such that the central administration complexity can be minimized, reducing a networkwide standard monitoring list (ISNWL) contained in the ADMF to an individual list (ISNL) for specific network nodes by virtue of monitoring subscribers which cannot communicate in the network node in question at that time and automatically deleting them from the ISNWL, reducing the ISNL or ISNWL to give a minimized individual list of subscribers which are to be observed (INS) by taking into account the maximum statistical traffic relations within the network node in comparison with the number of similar network nodes in the whole network and the maximum node performance, and using the reduced list (INS) as the list for the address comparison between each data packet which is to be conveyed and the monitoring list thereby minimizing the processing complexity.
