Abstract
A communication system includes housing equipment, a relaying apparatus that communicates with the housing equipment, and a management device that communicates with the relaying apparatus via a communication network. The management device is configured to store user identification information sent from a communication terminal that communicates with the management device via the communication network, and association information associated with identification information of the relaying apparatus sent from the relaying apparatus, and permit first communication via the management device between the communication terminal and the relaying apparatus that have been associated with each other in the association information. After the first communication is permitted, if no communication is performed from the relaying apparatus or the communication terminal to the management device during a predetermined first period, the management device is configured to prohibit the first communication in and after the first period.
