Abstract: PURPOSE: A method for processing a real time traffic statistic data of a base station is provided to implement a real time analysis of a base station traffic in BSM(Base Station Manager) and easily adapting to a simulator and statistic graphic. CONSTITUTION: A parent SMM(Statistics Measurement Manager) reads PID(Process ID) from a data base file from BIM(Bsm Initialization and Maintenance)(S10-S16). Thereafter, it is judged whether there is a child SMM. If there is not the child SMM, the child SMM is generated. If there is the child SMM, the routine is completed, and then the child SMM is generated(S17-S19). The generated child SMM reports its PID to the parent SMM. Then the parent SMM stores the PID into the data base file(S20,S21). The child SMM generated in S18 is reported to the parent SMM.

Abstract: PURPOSE: An apparatus for wirelessly connecting a mobile phone with a data terminal is provided to wirelessly connect the mobile phone with the data terminal by a radio frequency(RF) signal, so as to remove crosstalks and noises between the mobile phone and the data terminal by a phase locked loop(PLL) as a frequency oscillator. CONSTITUTION: A wireless connector transmits a data signal. A low noise amplifier(LNA)(312) receives the data signal transmitted via a duplexer(311), and firstly amplifies the signal. The amplified signal is converted into an intermediate frequency(IF) signal. An IF band filter(315) filters a signal transmitted from an IF mixer(314) to remove signals except IF bands, and passes an IF signal only. Amplifiers(316,325) amplify the IF signal and transmit the signal to a baseband mixer(318) and a central processing unit(CPU)(326). The baseband mixer mixes a second reference frequency with the IF signal to convert the IF signal into a baseband signal, and transmits the baseband signal to a demodulator(319). The demodulator demodulates the baseband signal to an original signal, and transmits the signal to a mobile phone or a data terminal. If the mobile phone or the data terminal transmits the baseband signal to a modulator(320), the modulator modulates the signal into a signal type appropriate for being loaded into a carrier, and transmits the signal to a high frequency mixer(322). The high frequency mixer mixes a third reference frequency with the baseband signal, and converts the baseband signal into a high frequency signal. A band pass filter(323) passes high frequency signals only, and removes other frequency bands.

Abstract: PURPOSE: A CVT(continuously variable transmission) using a friction gear is provided to decrease necessary components by not using an additional clutch or flywheel outside a CVT and to enhance power delivery efficiency by reducing the size or weight of the CVT. CONSTITUTION: A CVT delivers driving power of an engine to a rotary shaft(8) connected to a driving shaft(2) through a spline(6). The rotary shaft delivers the power to a driving friction gear(12) through a flywheel(10). In a neutral state of a shift lever, hydraulic pressure is not supplied from a hydraulic chamber(21). The rotary shaft moves toward an insertion direction into the spline by a tensile spring(34) and the driving friction gear is separated from upper/lower variable friction gears(20,22) to interrupt the power. The hydraulic pressure flows through an oil passage(36) when a vehicle moves forward. The friction gear overcomes the tension of the tensile spring and a taper friction surface is introduced between taper friction surfaces of the variable friction gears(20,22). The friction gears(20,22) are spread by overcoming elasticity of a compressed coil spring(26). A contact portion between the friction gears(20,22,12) has different linear velocity to deliver continuously variable power. The variable friction gears(20,22) are contacted with the friction side of a driven friction gear(14) to deliver the driving power.

Abstract: PURPOSE: A method for improving a communication rate of a facsimile is provided so that a fax data error can be prevented and a data communication rate can be improved, by controlling a data transmission speed according to a state of a communication path. CONSTITUTION: A transmitting side transmits fax data to a receiving side through a communication path. Firstly, the receiving side receives transmission speed information of the fax data from the transmitting side(S100). After receiving the transmitting speed information, the receiving side receives transmission state information of the communication path(S200). When a transmission state error is generated(S500), the state information that reception of the fax data is impossible is transmitted to the transmitting side(S600). When receiving the state information that reception of the fax data is impossible, the transmitting side reduces a transmission speed of the fax data, and re-transmits the fax data to the receiving side. Accordingly, when the fax data is received on the noisy communication path, the data transmission speed is controlled according to the state of the communication path, thereby reducing the fax data without an error.
