ABSTRACT:
A mobile station (303) provides seamless mobility across multicast domains for communicating with a multicast group (109) in a telecommunication system (300) that includes a home domain (102) and a visited domain (302). The mobile station (303) includes a local source address (324) and a home address (322). The mobile station (303) also includes a domain detector (305) for detecting a current domain of the mobile station (303), a comparator (307) for comparing the current domain of the mobile station with a previous domain of the mobile station (303) to generate a comparison result; and a multicast mode switch (326) coupled to the comparator (307) for switching between the local source address (324) and the home address (322) to select a source address for communicating with the multicast group (109) as a function of the comparison result.
