network-based mobility management system and method for mobile multicast service handover
摘要
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.
