Title:
COMMUNICATION SYSTEM AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/016183
Kind Code:
A1
Abstract:
The present invention provides a communication system and a communication device which make it possible to create a state where a slave machine has entered a communication network in a shorter time even if a master machine and/or the slave machine is restarted. In a communication system (1), a salve machine (20) enters a communication network after search processing and authentication processing, and communicates with a master machine (10). The master machine (10) is provided with a processing unit (12) and a nonvolatile storage unit (13), and the slave machine (20) is provided with a processing unit (22) and a nonvolatile storage unit (23). The storage unit (13) and the storage unit (23) store entry information. A case where at least one of the slave machine (20) and the master machine (10) is restarted after the entry of the slave machine (20) into the communication network is assumed. In this case, the processing unit of this machine uses the entry information stored in the storage unit of the machine immediately before restarting to bring the slave machine (20) into the state of having entered the communication network without performing communication related to the search processing and the authentication processing with the other machine.
