摘要： A method is related to support a QoS service at a handed over network in heterogeneous networks. A serving network requests the mobile terminal to offer demand QoS information, when there is a need of handover. The mobile terminal sends a response message containing the demand QoS information to the serving network, and each candidate network maps the demand QoS information to its network resources to judge whether or not to support the QoS service. And the serving network determines one of the candidate networks that can support the QoS service depending on the judgment of the candidate networks, and provides information on the determined candidate network to the mobile terminal such that the mobile terminal is handed over to the determined candidate network.

摘要： A vertical handover method between heterogeneous wireless networks is provided to offer mobility with minimum packet loss until an MN(Mobile Node) completes a BU(Binding Update) process while moving to a new network from a previous network in an MIH(Media Independent Handover)-based network environment where a WiBro(Wireless Broadband Internet) network and a WLAN(Wireless LAN) exist together. Based on the information received through an MIH message, an MN prepares for handover to a WiBro network. In this case, the MN activates a WiBro interface(S304). Then the MN sends an "MIH_handover_notify" message to an old AR(Access Router)(S306). Receiving the MIH_handover_notify message, the old AR sends an "MIH_handover_notify_request" message to a new AR(S308). Receiving the MIH_handover_notify_request message, the new AR starts buffering for the data delivered to the MN, and creates a tunnel(S310). The MN transmits a router solicitation message to the new AR through an AP(Access Point)(S312), and receives a router advertisement from the new AR(S314). Afterwards, the MN transmits a BU message to an HA(Home Agent)(S316), and receives a response message from the HA(S318). At this moment, the HA sends an MIH_FORWARD message to the old AR(S320). Receiving the MIH_FORWARD message, the old AR delivers packets, which was buffered before handover, to the new AR through the tunnel(S322).
