Zusammenfassung:	A method, and system for routing multicast data traffic to a mobile node (48), e.g. a mobile receiver or a Mobile Router, in a packet data network (41), for example IP multicast in an IPv4 or an IPv6 network, comprising: a home agent (52) receiving multicast group membership information from a mobile node (48) located outside the home network (50) of the mobile node (48); the home agent (52) forwarding the multicast group membership information to a router chosen to serve as a multicast router proxy (56); the multicast router proxy (56) joining a multicast group based on the multicast group membership information from the mobile node (48); and the multicast router proxy (56) forwarding multicast data traffic to the mobile node (48). The choice of the router to serve as the multicast router proxy (56) may be determined by the home agent (52).
