Abstract: The present invention provides a technology capable of providing corresponding information to an overlay network by sorting the kinds of wireless access networks, neighboring node grouping, and the current location of a user terminal by extracting the configuration information of a second layer and a third layer network according to the movement of the user terminal in a mobile environment. According to the present invention, an apparatus for optimizing the overlay network optimizes the configuration of the overlay network using mobility information generated based on the equipment information of the network. Therefore, the apparatus saves the physical network resources by reducing the data transmission traffic of the physical network and network delay time. In addition, the apparatus may connect to various overlay networks by organizing an interface to provide independent mobility information to a platform.

Abstract: PURPOSE: A network based mobility management system and mobile multicast service handover method are provided to support successive handover for multicast service traffic which uses handover between heterogeneous networks by enabling a mobile node to use a multicast service. CONSTITUTION: An HCA(Handover Control Agent)(22) manages multicast group information between MR(Multicast Router)(20) and an MICS(Mobility Information Control Server)(24). When handover is generated in MN(Mobile Node)(26), the HCA releases a multicast group without intervening in the MN. The HCA supports the multicast traffic handover of the MN. The MICS(Mobility Information Control Server) manages the multicast group information by receiving the multicast group information from the HCA. The MICS supports the multicast traffic handover of the MN by communicating with the HCA.
