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 heterogeneous network system performs a vertical handover based on media independent handover (MIH) in different networks in which a WiMAX (Wireless Broadband Internet) network (or a WiBro (Wireless Broadband Internet)) and a WLAN (Wireless LAN) network are coexisted. The heterogeneous network system cyclically acquires neighboring network information in advance through a media independent handover server, and performs new address (NCoA) generation at a handover preliminary time. And then DAD (Duplicate Address Detection) and BU (Binding Update) are performed. Accordingly, the vertical handover between different networks can be performed to receive packets from a switched network while a handover delay time is minimized.

摘要： A method of performing a vertical handover between different wireless networks based on media independent handover (MIH) includes the steps of checking a link state of the first network to transmit a handover notify message from the mobile node to an old access router when a handover is needed, and transmitting a handover request message from the old access router to a new access router to form a tunnel to exit toward the old access router. Thereafter, packets to be transmitted to the mobile node through the first network are buffered in the old access router. After changing the wireless service from the first network to the second network the mobile node, the packets buffered in the old access router is then transmitted to the new access router, and the mobile node receives the packets through the second network.
