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 buffer management method in a mobile IP(Internet Protocol) network for ocean telematics is provided to manage TCP flows which passes through a congested base station by using a base station packet buffering method. CONSTITUTION: It is determined whether a portable terminal is moved to a congested base station of a sub-network. When the portable terminal is moved to the congested base station, influence on TCP flows is confirmed by considering hand-off arrival distribution in the congested base station. The TCP flows passes through the congested base station by using a predetermined base station packet buffering method. A buffer is managed by a drop-tail method and an RED(Random Early Detection) method according to the hand-off arrival distribution.
