COMMUNICATION TERMINAL DEVICE, COMMUNICATION SYSTEM, AND METHOD OF CONTROLLING COMMUNICATION TERMINAL DEVICE

摘要

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.

1. A communication terminal device comprising:
a wireless communication unit configured to wirelessly communicate with control devices; a detection unit configured to detect a control signal instructing start of registration processing for causing a desired control device among the control devices to register the communication terminal device as a target to be controlled; a channel selection unit configured to sequentially select, from a plurality of frequency channels, a frequency channel to be used in transmission of a beacon request for requesting each of the control devices to transmit a beacon signal; a first transmission control unit configured to transmit, via the wireless communication unit, the beacon request to the control devices by using the frequency channel selected by the channel selection unit; and a receiving unit configured to receive, via the wireless communication unit, the beacon signal transmitted from each of the control devices in response to the beacon request, wherein the channel selection unit is configured to select at random a first frequency channel to be used in transmission of the beacon request from the frequency channels, when the detection unit detects the control signal.
