Patent ID: 7796620

Claim:
A method for establishing a multi-media connection in a communications system based on packet oriented communication, comprising: providing a first station only supporting IPv6 data-packets, providing a second station only supporting IPv4 data-packets; providing a media relay station; and establishing a communication between the first station and the second station at least partially via the media relay station; wherein the media relay station translates IPv4 data-packets into IPv6 data-packets and vice versa; wherein the media relay station functions as a traversal using relay network address translator (TURN) relay station; and wherein when the first station is calling the second station or the second station is calling the first station, the method further comprising: supplying an IP address and port of the calling station as a first candidate for communication, the supplying being done via the calling station; retrieving at least one IP address and port by the calling station from the TURN relay station as a second candidate; supplying an IP address and port of the called station as a third candidate for communication, the supplying being done via the called station; testing in such a manner that for each pair of candidates comprising one of the candidates supplied by the calling station and one of the candidates supplied by the called station using the same IP protocol it is analyzed whether connectivity is achieved; and establishing a multi-media communication between the first station and the second station via the TURN relay station using the adopted addresses and ports when the test results show that connectivity is achieved between the calling station and the called station using the address and port supplied by the TURN relay station and submitted as the first candidate or the second candidate by the calling station and the address and port submitted as the third candidate by the called station.
