A control device includes: a receiving unit that receives a first beacon request for performing registration processing from a communication terminal device; a detection unit that detects a control signal indicating a request for starting the registration processing; a registration control unit that starts the registration processing when the detection unit detects the control signal and executes the registration processing for a certain period; and a transmission control unit that: transmits the beacon signal when the receiving unit receives the first beacon request in a period during which the registration control unit is executing the registration processing; and avoids transmitting the beacon signal when the first beacon request is received in a period during which the registration control unit is not executing the registration processing.

Control device, communication system, and method for registering terminal devices and scanning for other control devices

A communication terminal device includes the following units. A detection unit detects a control signal instructing start of registration processing. A channel selection unit selects at random, from a plurality of frequency channels, the first frequency channel to be used in transmission of a beacon request when the control signal is detected. A scan control unit transmits the beacon request to the control devices by using the selected frequency channel. A receiving unit receives the beacon signal transmitted from each of the control devices. A list storage unit stores a predetermined parameter included in the beacon signal and the frequency channel in association with each other. A registration control unit transmits a registration request signal to the control device.
