20080198992 | Method for Setting Up a Multimedia Connection In Case Of Cascade Connection Transfer - The invention concerns a method for setting up a multimedia connection via a packet-switching computer network between at least one first calling subscriber (A-Tln) and at least one first called subscriber (B-Tln), the called subscriber terminal (B-Tln) triggering a cascade call transfer to other subscriber terminals (C-Tln, D-Tln). The invention is characterized in that the multimedia connection of the calling subscriber (A-Tln) to the terminal of the first called subscriber (B-Tln) is first set up via a network element (PR) of the computer network. Then, the terminal of the first called subscriber (B-Tln) transmits to the network element (PR) the connection transfer to another terminal (C-Tln, D-Tln) and the data associated with said other subscriber terminal (C-Tln, D-Tln). The network element (PR) then retransmits, while maintaining the multimedia connection to the calling subscriber (A-Tln), the setting up of the connection to said other subscriber terminal (C-Tln, D-Tln). The invention thus ensures in simple manner that a specific network element (PR) continues, notwithstanding the cascade call transfer, to participate in the setting up of the multimedia connection, thereby enabling the multimedia connection to be taxed, a legal interception to be performed and traffic measurements to be made. | 2008-08-21 |
