Abstract
A procedure from when device registration is completed until an always-on connection session with a server apparatus is established is simplified. Upon receiving a start request for directly accessing a controlled device from a controlling device via a service server, a direct-access management server transmits a direct-access URI obtaining request to the controlled device. The controlled device transmits a direct-access-port NAT setting request to a router. Upon receiving a notification of a global-IP-address and port-number obtaining error from the router, the controlled device transmits, to the direct-access management server, an error code for giving an instruction for a new remote video-recording reservation using tunneling. Upon receiving the error code, the direct-access management server assigns a tunneling port in the server, creates a direct-access URI based on the information of the port and so on, and transmits the direct-access URI to the controlling device via the service server.
