MEDIA STREAM GROUPING IN MULTIMEDIA COMMUNICATION NETWORKS

摘要

The invention refers to a first method for controlling a media session involving a plurality of media streams within a communications network,wherein a media control node (104) determines (S13) that selected media streams out of the plurality of media streams are associated to each other in a media session, generates (S14) an instruction to group the selected media streams of the media session, and transmits (S15) the instruction to group the selected media streams to the media resource node (108), an a corresponding second method for initiating a media session involving a plurality of media streams wherein a further media control node (102) determines (S6) grouping capabilities of the further media resource node (106) to group selected media streams out of the plurality of media streams generates (S7) in dependence said grouping capabilities a session offer comprising an information of grouping the selected media streams, and transmits (S8) the session offer to the further media resource controller (104).The invention further refers to corresponding media control nodes (102, 104) to a communication network an to programs for performing each of the methods.
