Abstract
The present invention relates to a method and a communication system for transmission of multimedia streams. Multimedia streams are transmitted in the communication system from a sending communication device to a receiving communication device at least partly via a wireless communication network. Information about the multimedia stream is transmitted to the receiving communication device comprising at least one parameter of the transmission of the multimedia stream for reservation of network resources. The parameter is the maximum bit rate which is needed for the transmission or the maximum service data unit size to be used in the transmission. It is also possible that both the mentioned parameters will be transmitted as attributes of the session description protocol. In an advantageous embodiment the receiving communication device informs the sending communication device about the QoS profile parameters which the wireless communication network granted for the transmission.
