PROBLEM TO BE SOLVED: To provide a communication system which allows for efficient registration of a terminal even if the node device at the movement destination of the terminal is participating in an overlay network different from that of a node device storing the authentication information of the terminal, and to provide a node device and a node processing program.SOLUTION: Upon receiving a registration request from a terminal that has moved bases, a first node device participating in a first overlay network transmits a registration request to a second node device participating in both first overlay network and second overlay network via the first overlay network, based on the identifier of the second overlay network. Upon receiving the registration request, the second node device transmits the registration request to a third node device storing the authentication information of the terminal via the second overlay network. The third node device communicates with the first node device and performs authentication of the terminal. |
