Abstract:
A cloud server acquires a stop period indicating a period during which a management server refrains from providing services; transmits connection requests to said management server if not in the stop period; establishes first communication session when establishment requests including the same address information as address information of connection destination included in the connection request are received from a relay device receiving connection requests forwarded from the management server after transmission of connection requests; transmits jobs to a control target device via first communication session; after first communication session is established, in response to acquisition of result of jobs executed by the control target device, if in the stop period, disconnects first communication session after the stop period finished; and if jobs are generated in the stop period, transmits to the control target device jobs generated in the stop period, via first communication session established before the stop period starts.
Abstract:
A communication system includes a plurality of devices, a plurality of communication relay apparatuses, and a management server. If the management server that has received from a cloud server a request to access a specific device has no communication session with a specific communication relay apparatus that has control over the specific device, the management server transmits a tunnel connection request to a substitute apparatus (another communication relay apparatus different from the specific communication relay apparatus) via a communication session between the substitute apparatus and the management server. The substitute apparatus transfers the tunnel connection request to the specific communication relay apparatus and causes the specific communication relay apparatus to return from a power saving mode. The specific communication relay apparatus then establishes tunnel communication with the cloud server on the basis of the tunnel connection request to relay communication between the cloud server and the specific device.
