A remote control system including a relay device capable of moving around a space where an appliance to be controlled is installed, and a communication device that is operated by a user, and communicates with the relay device. The relay device is controlled by the communication device, and includes an imaging unit, a sending unit that sends a captured image to the communication device, and a sending unit that wirelessly sends an instruction signal to the appliance to be controlled. The communication device includes a storage unit that stores data on an image of the space captured in advance, data on a partial area included in the image, and data on at least one of a request for movement to a destination and a request for transmission of an instruction signal, in association with each other.

Remote control system, remote control method, communication device, and program

A mobile communication terminal performs: registering a length of time starting at a time when an identifier of a base station is detected by a first communication unit, the identifier being transmitted by the base station accommodated in a first communication network, and ending at a time when the first communication unit accesses an access point accommodated in a second communication network in association with the identifier, the access point having an accessible range smaller than that of an accessible range of the base station; and starting, at the second first communication unit, a search for access information transmitted by the access point when a reference time determined based on a length of time associated with the registered identifier has passed a time when the identifier is detected, in a case where the identifier detected by the first communication unit is stored.
