Patent ID: 8259670

Claim:
A handover method, which is performed in a mobile node (MN) that moves between different types of networks and has a plurality of interfaces supporting the different types of networks, the handover method comprising: obtaining from a node that connects the MN to a first type network, network information indicating that the MN moves from the first type network to a second type network, wherein the network information includes an identifier of the second type network; determining by only the MN whether to change networks based on an intensity of a signal received using an interface supporting the first type network according to whether the network information is obtained; and selectively performing a handover between the first and second type networks based on the determination results, wherein the network information including the identifier of the second type network, is transmitted from the node to the MN, one of periodically and according to request of the MN and an interface supporting the second type network is enabled based on the identifier of the second type network included in the network information.
