COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

A communication system includes: a communication device that is connected to a communication line and that performs communication via the connected communication line using a communication message including a data area in which data is stored and an identifier area in which a communication identifier determined to correspond to the data is stored; and a gateway that is connected to a plurality of the communication lines and that relays a communication message among the plurality of communication lines. The communication device transmits a communication message, in which user data and a communication identifier corresponding to the user data are stored in the data area and a relay identifier for allowing the gateway to specify a communication line through which the user data stored in the data area is transmitted in the identifier area, to the gateway.
