Mobility Handling For Multicast Services |
摘要 |
A method of handling mobility of a sender in a multicast packet sending scenario. The method comprises firstly establishing a multicast tree across a packet data network and transmitting multicast packets from the sender to a plurality of receivers via said multicast tree. Prior to a mobility event in respect of said sender, a suitable transfer anchor node is identified within said network, and the tree re-rooted to that transfer anchor node. Subsequently, multicast packets are transmitted from said sender to said transfer anchor node and injected into the multicast tree at said transfer anchor node. Following said mobility event, said sender continues to send multicast packets to said transfer anchor node for injection into the multicast tree.
