<p>A handover method for preventing packet loss by applying FMIPv6 in a PAR of a potable Internet system is provided to generate a unidirectional tunnel between a serving cell and a target cell, transmit a transmitting packet through the tunnel, delete the unidirectional tunnel during a reactive mode of the FMIPv6 after a handover process at the target cell and generate a bidirectional tunnel instead of the unidirectional tunnel, thereby preventing the packet loss. A handover method comprises the following steps of: generating a unidirectional channel between a terminal and a serving PAR(Packet Access Router) while performing handover for the terminal, and receiving un-transmitted data, which will be transmitted from the serving PAR to the terminal, through the unidirectional channel(S122,S124); and generating a bidirectional channel, for data transceiving between the serving PAR and the terminal, between the terminal and the serving PAR while performing FMIPv6(Fast Mobile Internet Protocol version 6) fast handover after performing the handover for the terminal(s136,s137).</p> |
