摘要：The invention relates to group communication services, i.e. communicationservices involving two or more users (or service participants). The invention provides amethod for distributing multicast data of a multicast service to different domains and amethod for distributing multicast data to service participants in a domain. Further, theinvention relates to a control node and system implementing the respective methods. Toimprove resource utilization when providing a multicast service, including inter alia PoCservices, to service participants the invention provides mechanisms to avoid unnecessarymultiplication of multicast data in the distribution tree for multicast services with serviceparticipants of different domains. For this purpose the controlling node that is initiatingthe multicast service upon request determined to which domains the multicast data is tobe provided and only forwards the multicast data on a per-domain basis. Another aspectof the invention is the avoidance of unnecessary duplications of multicast data withinindividual domains.
