  • Application examples for specific multicast groups are, for example, news groups, audio and video streaming, distributed applications, etc.
  • Point-to-multipoint services such as MBMS are therefore pure downlink services, ie only data or messages from the radio network such as UTR are sent to the mobile devices of a certain group, but not data from these mobile devices in the opposite direction within this service to the radio network.
  • MBMS data are sent from a network component which provides the MBMS service (but has been omitted in FIG. 1 for the sake of clarity) to the UMTS core network CN and from there via the UTRAN radio network to the mobile radio devices MSI to MS4 in the different radio cells FZ1, FZ2, FZ3 transmitted.

  • This independent control signal which is transmitted in advance on the same transmission paths as the data of the point-to-multipoint service to be transmitted later, to the members of the respective group entitled to receive, is indicated in FIG. 1 by dash-dotted arrows CS. Since this control signal CS provides the respective mobile radio device, such as MS3, with information about which mobile radio device capabilities or properties are required for the proper or flawless reception of the group service subsequently sent, it can decide independently whether these conditions are met fulfilled, or its skills are inadequate. If the mobile radio capabilities required for this specific service are not met, the decision is preferably made not to receive the specific service.
