Method and apparatus for tunneling service of explicit multicast in mobile ip network

This invention relates to the explicit multicasting tunneling service method and equipment in a move IP network for transmitting a multicast packet to two or more move loads in 效率. In the tunneling service method and equipment for transmitting to two or more move loads, this invention the multicast packet received from the partner load - move load, A multicast packet is received from - which uses a common area of care address, and a partner load, The move load located on the course which carries out tunneling of the multicast packet received among move loads is grasped, [two or more] The explicit multicasting tunnel header which makes a destination address the common area of care address of a move load located on the course which carries out tunneling is generated, The multicast packet received by the generated explicit multicasting tunnel header is encapsulated. The multicasting tunneling service method and equipment in the move IP network characterized by carrying out tunneling of the encapsulated multicast packet to a move load are offered.
