COMMUNICATION TERMINAL, COMMUNICATION DEVICE, COMMUNICATION MANAGEMENT DEVICE, COMMUNICATION SYSTEM, NETWORK JOINING METHOD, AND NETWORK JOINING PROGRAM

摘要

The present invention provides a communication terminal (1) that performs communication for a second service via a network provided with a plurality of smart meters and constructed for a first service. When a network joining request is transmitted from a communication terminal not belonging to the network, the smart meters determine whether or not to transmit, to the communication terminal, a response to the joining request on the basis of whether or not the communication terminal is registered in the network. The communication terminal (1) is provided with a control unit (102) that generates a joining request for joining a network, and a communication processing unit (101) that transmits the joining request generated by the control unit (102) to one or more of the plurality of smart meters. Upon receiving a response to the transmitted joining request, the communication processing unit (101) passes the response to the control unit (102). The control unit (102) determines a smart meter that is to serve as a communication partner in network joining processing on the basis of the response received from the communication processing unit (101).
