摘要： A method and device for registering a multicast source and establishing a multicast path are disclosed. The method includes: after receiving a multicast message of a multicast source, a designated router DR to which the multicast source belongs encapsulating a multicast header for the multicast message, wherein a target address of the multicast header is a multicast address, and a source address of the multicast header is a proxy care-of address of the multicast source; and after encapsulating the multicast header for the multicast message, encapsulating the multicast message as a registration message to send to a rendezvous point. In the embodiments of the present invention, with the proxy care-of address of the multicast source in a PMIPv6 domain, and by the provided method for establishing the multicast path, the multicast routing efficiency and the multicast performance can be improved.

摘要： The present embodiment discloses a registration method, intercommunication method, handover method for a mobile node and a network element. The intercommunication method for a mobile node includes: after an enhanced mobile access gateway receives a data packet transmitted by the mobile node to a peer node for the first time, if the enhanced mobile access gateway provides an ePMIP service to the mobile node, the enhanced mobile access gateway judging whether a peer mobile access gateway to which the peer mobile node is currently attached provides an ePMIP service to the peer mobile node, and if so, forwarding the data packet in an ePMIP manner, and creating a local forwarding entry to instruct a subsequent packet to be forwarded in the ePMIP manner, and if not, forwarding the data packet in a PMIP manner, and creating a local forwarding entry to instruct a subsequent packet to be forwarded in the PMIP manner.
