Abstract: A wireless LAN base station scans frequency channels available for use in a wireless LAN, detects a beacon signal of a near-by wireless LAN base station, and thereby the number of the near-by base stations in the wireless LAN is notified. The notified number of the near-by base stations is recorded in a network table. A wireless LAN base station which should determine a radio channel in the next is determined, based on the recorded number of the near-by base stations, using a wireless LAN base station having a smaller number of the near-by base stations as the starting point of radio channel determining process, after the wireless LAN base station at the starting point determines a radio channel. By repeatedly carrying out the above-described operation, the radio channels of the whole wireless LAN are automatically determined.

Abstract: A wireless LAN base station is provided with a noise signal scanning antenna separately from a wireless signal reception antenna. An attenuation circuit section attenuates the received signal from the noise scanning antenna according to an attenuation factor from an attenuation factor storage section. A distance setting storage section stores a distance between the wireless signal reception antenna and the noise scanning antenna. An attenuation factor storage section holds pieces of data each of which indicates the relationship between the distance between the antennas and an attenuation factor in the form of a table. An attenuation circuit section employs the attenuation factor so as to attenuate the received signal from the noise signal scanning antenna. A subtraction circuit section subtracts an output signal of the attenuation circuit section from the signal from the wireless signal reception antenna, and reduces or eliminates a noise from the received signal from the wireless signal reception antenna.

Abstract: First and second telephone sets each comprise telephone set control units, voice codecs, and accumulating units. When the first telephone set, which is a subscriber of an internet service provider network, sends out internet service connection point data to the second telephone set, the second telephone set connects itself to the internet service provider network with reference to data in its accumulating unit and starts the voice codec. Then, the first telephone set connects itself to the internet service provider network and starts the voice codec. Thus, internet service telephone communication is made.

Abstract: Unauthorized access from a network to a terminal is prevented. If a signaling packet received from an external terminal contains a virus, the signaling packet is discarded. If the signaling packet does not apparently contains a virus, an unnecessary part is deleted and the signaling packet is transferred to an internal terminal in response to a polling signal. A port number described in a response packet received from the internal terminal is translated to a different port number. If a session packet received from the external terminal does not conform to a predetermined protocol, the session packet is discarded. If the session packet received from the external terminal conforms to the predetermined protocol, a port number is subject to reverse translation and a resultant session packet is transferred to the internal terminal.

The assistant mask layer includes first regions, each of which corresponds to one of the dummy cells. The step (b) is a process of checking whether or not the one of main mask layers and the merged assistant mask layer agree with a design rule. The step (c) is a process of replacing the one of main mask layers with another of the main mask layers, into which the assistant mask layer is merged, when a violation against the design rule is found in the step (b).
