Abstract
Upon receiving an initial media session invitation request from a first media communication device (UEA), such as originating user equipment or an originating media communication server, a second media communication device (PoC server), such as a media communication server responds to by sending a media inactivity indication to the first media communication device and setting the media inactive, while continuing the media session establishment at the same time. When the second media communication device receives a final response or a response from destination user equipment, the second media communication device sends a media activity indication to the first media communication device, thereby indicating that the media are now active. Standard messages can be used in their original context, while the use of the media inactivity and media activity control during the session establishment enables a controlled way to pre-establish the originating leg of the media session before the destination leg of the media session has been completed. The first media communication device will start sending media traffic only in a controlled manner either after receiving the media activity indication or after receiving a specific floor control command
