Abstract: PURPOSE: A PFMIPv6 based vertical handover method is provided to continuously offer a multimedia service by connecting various APs(Access Point) through a terminal including a multi-wireless interface. CONSTITUTION: When a report message is transmitted by an MIHF(Media Independent Handover Function) of a corresponding terminal, the MIHF transmits a network layer message which notifies the initialization of handover to a previous MAG(Mobile Access Gateway). When the previous MAG receives the layer message, the previous MAG previously transmits information which is the same as an MN-ID(Mobile Node-Identification) and LMAA to a new MAG. After an IP(Internet Protocol) address is set, the new MAG transmits a PBU(Proxy Binding Update) message and receives PBA(Proxy Binding Acknowledgement).

Abstract: PURPOSE: A handover method of PMIPv6(Proxy Mobile Internet Protocol version 6) multicast traffic for a wired network in a ship is provided to reduce handover delay time by adding a multicast LMA(Local Mobility Anchor) for solving a tunneling overlapping phenomenon. CONSTITUTION: A multicast LMAA(LMA Address) is added to an MN(Mobile Node)-profile. The multicast LMAA is added to the MN-profile in an MAG(Mobile Access Gateway) in order to separate a normal LMA managing the unicast traffic of an MN from a multicast LMA managing the multicast traffic. Delay time due to a multicast group in a handover process is reduced by transmitting information related to multicast by using a PFMIPv6 message. A binding update procedure is executed by transmitting the multicast information of MN by using the message in the handover process.
