Abstract
The present disclosure refers to a method and a system for providing lawful interception in a peer to peer communication (P2P) over a telecommunication network comprising establishing a first media path, between a first and second communication devices, for a media stream through a central node of the telecommunication network; looking for a second media path, between the first and second communication devices, through a P2P connection; in case of the P2P connection is found, duplicating the media stream; transmitting the duplicated media stream both to the central node and through the P2P connection; and reproducing the duplicated media stream transmitted through the P2P connection.
Claims20
A method for providing lawful interception in a peer to peer communication (P2P) over a telecommunication network, the method comprising the steps of:
- a) establishing a first media path, between a first and second communication devices, for a media stream through a central node of the telecommunication network;
- b) looking for a second media path, between the first and second communication devices, through a P2P connection;
- c) in a case where the P2P connection is found, duplicating the media stream at the first communication device;
- d) transmitting the duplicated media stream from the first communication device both to the central node and through the P2P connection to the second communication device;
- and
- e) reproducing, by the second communication device, the duplicated media stream transmitted through the P2P connection.
The method according to further comprising:
- muting the first media stream, at the first or second communication device receiving the media stream through the central node.
A system for providing lawful interception in a peer to peer communication (P2P) over a telecommunication network, the system comprising:
- a first communication device configured to establish a first media path with a second communication device, for a media stream through a central node;
- configured to look for a second media path, with the second communication device, through a P2P connection;
- to duplicate, in a case where the P2P connection is found, the media stream;
- and to transmit the media stream both to the central node and directly to the second communication device through the P2P connection;
- a second communication device configured to receive media streams both through the central node and through the P2P connection and to reproduce the media stream transmitted through the P2P connection;
- and
- a central node configured to receive the duplicated media stream from the first communication device.
A method for providing lawful interception in a peer to peer communication (P2P) over a telecommunication network, the method comprising the steps of:
- a) establishing a first media path, between a first and second communication devices, for a media stream through a central node of the telecommunication network;
- b) looking for a second media path, between the first and second communication devices, through a P2P connection;
- c) duplicating the media stream at the first communication device;
- d) transmitting the duplicated media stream from the first communication device both to the central node and through the P2P connection to the second communication device;
- and
- e) reproducing, by the second communication device, the duplicated media stream transmitted through the P2P connection.
