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).
