METHOD AND DEVICE FOR TAPPING USEFUL DATA OF MULTIMEDIA CONNECTIONS IN A PACKET-ORIENTED NETWORK

摘要

The problem underlying the invention is that conventional multimedia connections such as videotelephony cannot be tapped according to LI (Lawful Interception) standards in a packet-oriented network. For this purpose, the inventive method and device use a control and a tapping device. The control, for the duration of a call, replaces the point-specific data of the respective partner end by the point-specific data of the tapping device, thereby guiding the useful data flows via said tapping device, tapping them and optionally adapting them to the interface of the tapping agencies.
