Verfahren zur Gesprächsdatenerfassung

摘要

The invention concerns a method of detecting and evaluating call data of a call directed from a terminal connected to a source network node to a terminal connected to a target network node in a communication network comprising a plurality of network nodes. Data-detection occurs in at least two network nodes, and the detected data of a plurality of network nodes are combined and evaluated. In the source network node a special call identifier identifying said node is allocated to the call and transmitted as a detectable datum to the network nodes participating in the call. The special call identifier is stored together with the call data in the network nodes detecting these data, and the detected data are combined independently of the call switching control system.
