There is disclosed a notification method in a communication system of notifying specific multifunctionality information between terminal stations. An expansion code is generated from both a user input code and a function identification code corresponding to a specific function. A transmission frame including the expansion code is also generated and transmitted to at least one of the terminal stations.

Method of notifying function identification information and communication system

A facsimile server includes: a communication section configured to receive a transmit file containing meta-information relating to a phone number and transmit information from an external device, a facsimile image generating section configured to convert the transmit information into a facsimile image, a phone number processing section configured to obtain the phone number from the meta-information, and a FAX modem processing section configured to connect to a public switched telephone network according to the phone number obtained by the phone number processing section and transmit the facsimile image to the public switched telephone network.

Facsimile server, facsimile system, and facsimile transmission method

A large amount of user information is transmitted with good efficiency by means of a high-speed downlink by making transmission rates of an uplink circuit and a downlink asymmetrical. The radio communication system includes a plurality of base stations, a plurality of terminals, an uplink established between each of the base stations and each of the terminals for the purpose of radio transmission of prescribed information from a terminal to a base station, and a downlink circuit established between each of the terminals and each of the base station for the purpose of radio transmission of prescribed data from a base station to a terminal. This radio communication system has a low-speed transmitting means, provided at the terminal, which transmits a radio signal at a relatively low transmission rate to an above-noted base station via the above-noted uplink, a low-speed receiving means, provided at the base station, which receives a radio signal sent at a relatively low transmission rate from the terminal via the uplink, a high-speed transmitting means, provided at the base station, which transmits a radio signal at a relatively high transmission rate to an above-noted terminal via the above-noted downlink, and a high-speed receiving means, provided at the terminal, which receives a radio sent at a relatively high transmission rate from the base station via the downlink.

A radio communication system includes one master station which performs transmission without being controlled by another radio station and which is configured to independently set a channel for use in a radio communication, and at least one slave station which belongs to the one master station and whose radio communication channel used and transmission/reception operations are controlled by the master station. When detecting an interference signal which disturbs the radio communication during operation, the one master station or the at least one slave station sets a first modulation scheme applied to the radio communication to the same second modulation scheme as a modulation scheme used in broadcast in order to convey information necessary for an evasive action to move to another radio communication channel.

Radio communication system capable of maintaining communication performed between master station and slave station belonging to such master station even when interference signal is detected

A wireless communication device that includes a wireless communication unit that performs a wireless communication in a first mode using a first frequency band serving as a first communication channel, and performs the wireless communication in a second mode using a second frequency band including the first communication channel and a second communication channel that is adjacent to the first communication channel. Also included is a detection unit that monitors each of the first frequency band and the second frequency band, outputs a first detection signal when an interference signal is detected in the first frequency band and outputs a second detection signal when the interference signal is detected in the second frequency band. Further included is a determination unit that determines whether the interference signal is in the first communication channel or in the second communication channel based on the first and second detection signals.
