Provided is a wireless base station capable of increasing an area of overlap between a cell of the wireless base station and a cell of an adjacent wireless base station before the wireless base station narrows a cell range or reduces transmission power. A wireless base station (-) includes a communication unit (A) and a control unit (B) that transmits, to a wireless base station (-) adjacent to the wireless base station (-), through the communication unit (A), an instruction signal that gives an instruction to expand a cell range of the wireless base station (-) in a direction of the wireless base station (-) before the wireless base station (-) narrows a cell range or reduces transmission power.

Wireless base station, core network device, wireless communication system, and wireless communication method

An operation procedure communication system includes an information processing device for communicating an operation procedure and an information processing device for receiving the operation procedure. The information processing device for communicating the operation procedure includes: an operation acquisition unit for identifying and storing an input applied to an own terminal device and various states of the own terminal device in a period from application of a first predetermined operation to application of a second predetermined operation; an operation conversion unit for converting operation log stored by the operation acquisition unit to a text and/or a file to be reproduced as depiction; and an operation procedure transmission unit for transmitting an operation explanation acquired by the conversion by the operation conversion unit via communications means. The information processing device for receiving the operation procedure includes an operation procedure presenting unit for presenting the operation explanation which is transmitted from the information processing device for communicating the operation procedure and acquired via the communications means to a user.

Mobile terminal device, operation procedure communication system, and operation communication method

A communication terminal is used in a wireless communication environment which involves a plurality of coexisting communication processes with upper limit values being set respectively therein for amounts of data to be transmitted. The communication terminal includes a compressor which compresses data to be transmitted, and a compression controller which controls the compressor to compress the data if the amount of the data to be transmitted is equal to or greater than the upper limit value set depending on one of the communication processes which is to be used to transmit the data.

An information processor includes a keyword registration means for accepting an input of a keyword composed of a predetermined character string and storing the accepted keyword in a storage device; and a content display means for displaying externally acquired content on a display device. The content display means is configured to display the content on the display device by replacing a character string in a preset range containing the keyword with other display data if the keyword stored in the storage device exists in character information contained in the content.

Information processor

A signal transmitted from a base station is received by a receiver. The received signal is supplied to an AGC amplifier and is then supplied to a demodulator, so that the signal is demodulated into baseband signals. The baseband signals are supplied to a baseband signal processor. The baseband signals are also processed through an instantaneous received power calculator, an average received power calculator, and a feedback AGC code generator to produce an AGC signal. The gain of the AGC amplifier is controlled based on the AGC signal. A fading pitch measuring device measures a fading pitch from the instantaneous power calculated by the instantaneous received power calculator. The average received power calculator changes averaging time required to calculate average received power depending on the measured fading pitch.

Automatic gain control method for radio communication mobile station

A method of performing transmit power control is performed based on ISCP which a mobile terminal calculates from a downlink received signal. A transmission/reception unit of the mobile terminal transmits and receives a radio signal to/from a radio base station through an antenna. A transmission/reception control unit performs control relating to the signal processing in the transmission/reception unit. A control unit Performs control concerning operation of each unit of the mobile terminal. A measurement unit measures ISCP and DPCH power from the signal received in the transceiver unit, and transmits the measured values to the control unit. A characteristic value conversion unit prepares a relation between the ISCP which satisfies a preset target BLER and the measured DPCH power, based on BLERs previously measured in a communication environment where the mobile terminal is located.
