Abstract:
In one aspect of the invention, audio and video user data are separated. The audio user data is conducted via a TDM loop, where it is tapped and the video user data is fed to the recipient via the packet network, the separated audio and video user data are then combined again.
Abstract:
The invention relates to a method and telecommunications system (SYS) for monitoring a data flow (DAT) in a data network (WWW) between at least two telecommunications terminals (TEA, TEB), which are connected to the data network via at least one access server (AAA, AAB). When monitoring, the data flow (DAT) between the telecommunications terminals (TEA, TEB) is rerouted from the access server (AAA, AAB) via a monitoring server (PRO), which makes a copy (KOP) of the data flow (DAT) and transmits it to an evaluation unit (ASW).
Abstract:
In one aspect, a method for tapping conventional multimedia connections such as video telephony according to Lawful Interception standards in a packet-oriented network is provided. A 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 the tapping device, tapping them and optionally adapting them to the interface of the tapping agencies.
