Abstract: An apparatus and a method for handover between heterogenous networks in a wireless communication system are provided to perform handover between heterogenous networks by using a medium independent handover technique based on a proxy mobile IPv6. It is checked whether candidate target networks which a terminal(200) selects support handover of the terminal in a serving network(210). The terminal selects a target network(220) for handover between heterogeneous networks. The serving network requests handover to the target network between the heterogenous networks of the terminal. If handover is requested in the serving network, the target network obtains a profile of the terminal from a policy storage unit.

Abstract: An apparatus and a method for managing a media independent hand-over service are provided to reduce unnecessary transactions and unnecessary power consumption. A process for setting the state information of an MIHF(Media Independent Handover Function) is performed(S410). A process for managing MIH(Media Independent Hand-over) services is performed on the basis of the state information of the set MIHF(S430). In the state information setting process, the state information of the MIHF is set as the first state when the MIHF is initialized or reset. When a peer MIHF is discovered at the first state, the state information of the MIHF is set as the second state information. At the second state, the state information of the MIHF is set as the third state information when the MIHF is registered to the peer MIHF.

Abstract: An apparatus and a method for decreasing hand-over delay in a broadband wireless communication system are provided to perform vertical hand-over and re-enter a target network when executing the vertical-hand-over, thereby performing the hand-over without disconnecting a service. A process for confirming whether there is a target network includes a process for obtaining neighboring network information from an MIH(Media Independent Handover)(301) and a process for confirming whether there is a target network capable of connecting in the neighboring network information(303). A process for confirming whether there is the target network when networking with a serving network is performed. When there is the target network capable of connecting with the serving network, a link up process toward the target network is performed(307). A de-registration process to the target network is performed, so that the communication state is changed into an idle mode(311). When performing the vertical handover through the target network, the network re-entry process is performed to the target network(317).

Abstract: A handover method among multi devices in heterogeneous networks and a system thereof are provided to continuously perform handover to devices belonging to homogenous or heterogeneous networks, thereby enabling a user to use the same communication service through different devices without disconnection. If a handover triggering event is generated, a serving apparatus obtains neighboring network information about at least one PoS through the first PoS(Point of Service)(210). The serving apparatus collects lists about one or more devices usable from one or more adjacent PoSs(220). If a suitable target device is selected, handover is performed from the serving apparatus to a target device(230). If the handover is completed, the serving apparatus releases the first data path(240).
