ABSTRACT:
The invention relates to a method and communication system allowing interception of a communication or connection of a target to be intercepted. According to preferred embodiments of the invention, interception triggering information is transmitted between the user plane and control plane (e.g. via Gr-, Gc-, Gi-interfaces). The system comprises at least one control means for handling signaling of a connection between a user equipment and another communication device, and a support element for transmitting traffic information between the user equipment and the another communication device. When the connection is to be intercepted, the control means is adapted to generate an interception information for informing the support element or another network element on an identification of the target to be intercepted. The support element is adapted to copy the traffic information to another network element for interception when receiving an interception information from the control means.
