Abstract: Disclosed is a high-speed vertical handover method in a MIH and PFMIPv6 environment. The method enables a corresponding feature via an MIH message without altering a link layer. In other words, a report massage is transmitted to a corresponding terminal′s MIHF, and the MIHF which received the message transmits a MIH_MN_HIrequest which is a network-layer message notifying the initiation of a handover to a PreviousMAG instead of a Handover initiation which is a conventional link-layer message notifying the initiation of a handover.
