Abstract: PURPOSE: A method for minimizing packet loss in handover between different mobile networks is provided to buffer data transmitted to a mobile terminal during handover through a home agent object to forward the data after the handover to the mobile terminal, thereby minimizing loss of a packet. CONSTITUTION: A mobile terminal transmits a handover direction message to a home agent object(S210). The home agent object buffers data transmitted to the mobile terminal(S220). The home agent object requests transmission of not transmitted residual packet data during a handover process to the first network. The not transmitted residual packet data is transmitted from the first network to the home agent object through a PMIP(Proxy Mobile IP) tunnel(S225). The home agent object forwards the data to the mobile terminal(S230).

Abstract: A tunneling method of a mobile terminal for supporting IP(Internet Protocol) mobility is provided to implement tunneling of the terminal by conducting a packet processing function on a device driver end(network driver end) when a mobile IP is used to support the IP mobility of the terminal mounted with a closed-source OS(Operating System) of an IP end. In case of movement detection(401), a mobile terminal decides whether a network where the mobile terminal is currently located is a home network or a visiting network(402). In case of the home network, the mobile terminal confirms whether an IP layer of a device currently connected to the home network is activated(403). If so, the mobile terminal transmits/receives packets by operating without an additional operation. In case of the visiting network, the mobile terminal inactivates an IP of a home device(406), and transmits/receives the packets(404).

Abstract: An apparatus and a method for service continuity between a UMTS(Universal Mobile Telecommunication System) network and a WLAN(Wireless LAN) are provided to enable an IWG(InterWorking Gateway), interworking with the SGSN(Serving GPRS Support Node) or GGSN(Gateway GPRS Support Node) of a 3GPP(Third Generation Partnership Project) network, to seamlessly provide a service to a mobile station in case the mobile station moves from the 3GPP network to a non-3GPP network or returns to the 3GPP network from the non-3GPP network. An apparatus for service continuity between a UMTS network and a WLAN comprises the first node, the second node, and an IWG(250). The first node, or an SGSN(220), executes packet data transfer with a mobile station(100) within service area of the UMTS network. The second node, or a GGSN(230), serves as a wireless gateway between the SGSN(220) and a packet data network(400), and allocates the first address to the mobile station(100) through the SGSN(220) for data communication with the packet data network(400). The IWG (250), when the mobile station(100) moves from the UMTS network to the WLAN, receives the first address, allocated to the mobile station(100), through the first interface from the GGSN (230) and provides a seamless service to the mobile station(100) by using the first address. Also the IWG(250) forms a tunnel with the mobile station(100) by using the first address.
