A technique is disclosed, according to which a mobile node, having a plurality of interfaces and performing communication according to flow information when an operator is performing communication based on the flow information as defined by a policy, can select an interface suitable for the flow and can perform communication. According to this technique, a mobile node (MN 10) having a plurality of interfaces has a list to indicate domain limited flows to be transmitted only within a specific network (a trusted network), and a list to indicate the trusted networks. When a certain interface performs handover, and in case there is a domain limited flow that uses the interface, it is decided whether the network of handover destination is a trusted network or not, and in case the network of the handover destination is not a trusted network, it is decided whether it is possible or not to transmit and receive the domain limited flow via another interface that is connected to the trusted network.
