Description

How to generate ringing tones from a cordless phone

The present invention relates to a ring ring tone generating method in a wireless telephone, and more particularly, to a ring ring tone generating method for generating ring ring tones at different times in a fixed device and a portable device when a call is made to a wireless phone.

Typically, a radiotelephone includes a fixing device and a portable device, and the fixing device is connected to a wire to directly communicate with the outside, and the portable device can communicate with the outside by the wireless communication with the fixing device. When a call is received from the outside, the ringing tone rings on the fixing device and the ringing signal is sent to the mobile device immediately by the ringing device. It was supposed to ring at the same time.

Such a conventional wireless telephone rings at the same time when a ringing ringing ringtone of a mobile device and a ringing ringtone of a mobile device ring at the same time. When trying to answer a call with a mobile device with a small ring tone, it was difficult to determine the location of the mobile device.

Accordingly, an object of the present invention is to provide a ringing ringtone generating method for ringing ringing with a time difference between a fixed device and a portable device when a call is received from a wireless telephone to solve the above problems.

Another object of the present invention is to provide a ring ringing tone generation method that enables a ringing ringing tone to be fixed to a fixed device and a portable device at a different time when a call is received from a radiotelephone.

To achieve the above object, the present invention provides a ringing tone in a fixed device in a ring-on time section of a ring signal when a telephone call is made to a wireless telephone, and a ringing tone in a portable device in a ring-off time section of the ring signal. It is characterized by.

The key matrix 100 includes keys for inputting various functions and control commands and numeric keys for performing a dialing function, and outputs key data corresponding to a key pressed by a user to the CPU 130. The voice processor 150 voice-processes the voice signal for the call connected to the trunk line. The microphone 200 inputs a voice signal. The speaker 190 outputs an electric voice signal as an audible signal. The first and second amplifiers 170 and 180 amplify and output the input / output signals of the microphone 200 and the speaker 190 to a predetermined level. The display device 120 displays each processing and operation state according to the key input state. The DTMF generator 140 generates a DTMF signal under the control of the CPU 130 and provides it to the voice processor 150. The ring detection circuit 210 detects a ring incoming from the trunk line and provides the ring to the CPU 130. The third amplifier 230 amplifies and outputs a voice signal and various transmission / reception data to a predetermined level. The RF transmitter / receiver 110 band-modulates the signal input from the third amplifier 230 under the control of the CPU 130 and outputs a radio wave through an antenna or demodulates a signal received through the antenna into a signal of a voice band. At the same time, data is output to the third amplifier 230.

The CPU 290 controls the overall operation of the portable device, and receives the ring ring tone generation control signal from the fixed device to control the ring ring tone during the idle period of the ring signal. The memory 270 stores passwords (IDs) and various programs of the portable device, and temporarily stores data generated during program execution. The key matrix 280 includes numeric keys for performing various functions and dialing functions, and outputs key data corresponding to a key pressed by the user to the CPU 290. The amplifier 360 amplifies and outputs a voice signal and various transmission / reception data to a predetermined level. The RF transmitter / receiver 350 transmits a transmission voice signal through an antenna under the control of the CPU 290, and demodulates a signal received through the antenna and outputs the signal to the amplifier 360. The microphone 340 inputs a voice signal. The speaker 330 outputs an electric voice signal as an audible signal. The first and second amplifiers 310 and 320 amplify and output the input / output signals of the microphone 340 and the speaker 330 to a predetermined level. The display device 300 displays an input state of a key and an operating state of the portable device under the control of the CPU 290.

1 to 4, the operation of the preferred embodiment of the present invention will be described in detail.

First, in step 101, when the fixing device as shown in FIG. 1 is in the standby state, the process proceeds to step 102. The CPU 130 of the fixing device checks whether a ring signal is detected from the ring detection circuit 210, and when the ring signal is detected, proceeds to step 103. In step 103, the CPU 130 of the fixing device generates a ringing tone from the fixing device during the ring-on period. Thereafter, in step 104, the CPU 130 of the fixing device checks whether the rest period of the ring signal is detected from the ring detection circuit 210, and returns to step 103 if the ring on time period is not the rest period of the ring signal. . Here, the ring signal is received from the trunk line as shown in 4A of FIG. 4, and the cadence of the ring signal is the same as that of 4B of FIG. 4 and has a period of ring on time and ring off time. The ringing ringer is stopped by repeating the ring ringing tone during the ring-off time period and repeating the ringing ringing tone in the ring-on time period. However, when the idle period of the ring signal is detected, the CPU 130 controls the RF transmitter / receiver 110 in step 105 to transmit wireless data on the ringing tone generating control signal to the portable device during the idle period of the ring signal. Then, the wireless data for the ring call generation control signal is applied to the CPU 290 through the RF transmitter / receiver 350 and the amplifier 360 of the portable device. At this time, the CPU 290 of the portable device controls to ring a ringing call during the rest period between the ring signals. After ring ringing sounds for the ringer during the ring-on time of ring cadence, and ringing ringing for the mobile device during ring-off time, the CPU 130 of the locker receives the call from the device or the mobile device in step 106. Search for. At this time, if the call is not answered, the process returns to step 102, when the ring signal is input, the ringing device and the mobile device alternately ring, and if the call is received from the device or the mobile device, the process proceeds to step 107. In step 107, the CPU 130 of the fixed device connects the call paths so that the fixed device that receives the call or the mobile device can make a call. Then, in step 108, the CPU 130 of the fixed device checks whether the call is completed. In other words, if the call is completed and on-hook, the mobile station enters the standby state in step 207.

As described above, in the present invention, ringing sounds of the fixed device and the portable device ring at different times in the wireless telephone, so that ringing sounds of the fixed device and the portable device can be clearly seen, It is advantageous to know whether the ringing bell is ringed on the portable device or to make a call by accurately recognizing the location of the portable device.
