Disclosed is a technique for enabling a mobile terminal, which is capable of using a plurality of communication routes for communication with a correspondent node, to select an appropriate communication route to communicate with the correspondent node. According to the technique, the mobile terminal (UE/MN 313B) requests a predetermined network node (P-GW 317) to detect whether or not the correspondent node (CN 318B) exists in the same domain. The P-GW monitors a packet sent from the CN to the UE/MN and, when detecting the packet, determines whether or not the CN exists in the same domain. In the case of determining that the CN exists in the same domain, the P-GW reports information that the CN exists in the same domain, to the UE/MN. The UE/MN selects an interface used for communicating with the CN, based on the reported determination result.
