Abstract: A handover method between heterogeneous wireless communication networks is provided to enable a mobile terminal to minimize the delay time generated when transmitting data in the handover between a 3GPP(3rd Generation Partnership Project) network and a non-reliable 3GPP network by performing the role of a virtual eNB. A registration procedure request to the first wireless network is received from a mobile terminal(10) of the second wireless network(S500). If the registration authentication for the mobile terminal is requested, the registration procedure request is approved(S510,S520). If the base station information of a destination location is received from the approved mobile terminal, a handover request message of the mobile terminal is transmitted to the destination-side base station(S560,S562). If a handover procedure completion message is received from the destination-side base station, a communication tunnel formed with the mobile terminal is released(S570,S590).

Abstract: A handover method for reducing packet loss is provided to be capable of shortening a handover procedure by previously allocating an address of a new subnet area to be handed over before the handover procedure is started, so as to cut down time for the handover procedure, thereby minimizing packet loss. A subnet address request message to be used in the second cell is received from a portable terminal, and the message is delivered to the second router(S302-S310). A response message corresponding to the subnet address request message is received from the second router, is converted, and the converted message is transmitted to the portable terminal(S320). A handover request message is received from the portable terminal(S330). Address information of the portable terminal, flow numbers, and context information including QoS(Quality of Service) information are transmitted to the second cell(S340). A tunnel with the second cell is generated, and packets to be transmitted to the portable terminal are transmitted to the second cell through the tunnel(S350).
