Abstract
The invention relates to a method for controlling the transmission of feedback of mobile terminals receiving via an air interface of a mobile communication system a multicast or broadcast service transmitted or forwarded by a feedback control entity and to a mobile terminal, the feedback control entity using this method. Further, a communication system comprising a feedback control entity and a mobile terminal receiving a multicast or broadcast service is provided. To enable configurable and adaptive feedback for multicast or broadcast services provided via an air interface maintaining the end-to-end session concept the invention suggests selecting a subset of the mobile terminals of the mobile communication system and which receive the multicast or broadcast service for providing feedback to a feedback control entity. In one embodiment of the invention the terminals may decide whether to provide feedback based on a probabilistic experiment performed based on parameters determined and provided by the feedback control entity.
