Multicasting over mobile IP network becomes more important with the increasing needs of supporting multimedia services in mobile network. IETF has suggested two approaches which are remote subscription and bidirectional tunneling for supporting mobility management in multicasting over mobile IP. And the advanced schemes such as Mobile Multicast (MoM), Range-Based Mobile Multicast (RBMoM) have been proposed. But, these protocols have problems - frequent reconstruction of multicast delivery tree, packet loss during handoff, convergence problem, and so on. In this paper, we propose to use preconfiguration of multicast delivery tree when mobile host enters the foreign network. It will decrease the frequency of multicast delivery tree reconstruction, and reduce the packet loss during handoff. Also using Keep Alive messages between foreign agents makes the signaling overload of networks diminished, because the number of foreign agents which are virtually connected with current foreign agent that mobile host attaches to will remain constant.
