Description

Device and method for adjusting talk level in wireless telephone

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for adjusting a talk level in a wireless telephone, and more particularly, to an apparatus and method for adjusting a conversation level during a call in a wireless telephone.

In general, a cordless phone can be used with a plurality of portable devices in one fixed device. The fixed device can be directly connected to the outside by being connected to a wire, and the portable device can communicate with the fixed device by wireless. You can talk to the outside. If the wireless telephone cannot hear the contents of the call well due to the loss of the line or the bad phone unit of the other party during the call, the mobile phone's keypad can be used to increase the level of the call and increase the level of the call. The signal was sent out loud. As such, in the related art, since the power of the battery mounted in the portable device is used to increase the transmission gain of the portable device, the current consumption of the battery increases when the transmission gain is increased, thereby shortening the battery discharge time when talking for a long time.

Accordingly, an object of the present invention is to provide a call level control apparatus and method for controlling a fixed device to amplify and transmit a call level using a portable device when the reception side of the other party is not good during a call in a wireless telephone. In providing.

Another object of the present invention is to extend the discharge time of the battery mounted on the portable device by remotely controlling the fixed device with the portable device when the other party does not hear the call during the call to amplify and transmit the level of the transmission signal in the fixed politics. The present invention provides an apparatus and method for adjusting a level of speech.

According to the present invention for achieving the above object, when the talk level increase key is pressed in a state of making a call to a mobile device, the talk level increase command data is transmitted to the fixed device, and the talk level increase command data is received from the fixed device. When the fixed device is characterized in that for transmitting and amplifying the transmission voice signal.

The CPU 250 controls the overall operation of the fixed device, and outputs a transmission gain control signal when a talk level increase command is received from the portable device to control the talk level to be increased. The memory 220 includes a ROM for storing various programs and a RAM for temporarily storing data generated during program execution, stores a password corresponding to a portable device, and has an area for setting various functions. The key matrix 230 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 300 voice-processes the voice signal for the call connected to the trunk line. The microphone 350 inputs a voice signal. The speaker 340 outputs an electric voice signal as an audible signal. The first and second amplifiers 320 and 330 amplify and output the input / output signals of the microphone 350 and the speaker 340 to a predetermined level. The display device 240 displays each processing and operation state according to the key input state. The DTMF generator 290 generates a DTMF signal under the control of the CPU 250 and provides it to the voice processor 300. The ring detection circuit 280 detects a ring incoming from the trunk line and provides the ring to the CPU 250. The third amplifier 270 includes a transmission amplifier and a reception amplifier, and amplifies and outputs a transmission / reception voice signal and various transmission / reception data to a predetermined level. The RF transmitter / receiver 260 band modulates a signal input from the third amplifier 270 under the control of the CPU 250 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 270. The hook switch 310 is connected between the trunk line (C.O) and the voice processing unit 300 to hook on / off according to the state of the handset.

4 is a control flowchart for increasing a talk level in a fixing device according to an embodiment of the present invention.

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

First, in step 101, the CPU 120 checks whether the portable device is in a trunk line call and proceeds to step 102 in case of a trunk line call. In step 102, the CPU 120 of the portable device performs a call function. At this time, if the other party cannot hear the contents of the call during the trunk line call, the user who is using the mobile device presses a call level increasing key provided in the key matrix 110. In step 103, the CPU 120 of the portable apparatus checks whether the talk level increase key signal is input from the key matrix 110, and if the talk level increase key signal is not input, the process proceeds to step 104. In step 104, the CPU 120 of the portable apparatus performs the call function at the current talk level. However, when the talk level increase key is input in step 103, the flow proceeds to step 105, where the talk level increase command data is generated and transmitted to the antenna through the amplifier 190 and the RF transceiver 180. In step 106, the CPU 120 checks whether a call is terminated by inputting a key from the key matrix 110. When the call ends, the CPU 120 proceeds to step 107 to switch to the standby state.

Meanwhile, referring to FIG. 4, when the call level increase command data is received from the mobile device during a call, the fixed device increases the call gain and transmits a voice signal. Referring to FIG. If there is a call, the process proceeds to step 202. In step 202, the CPU 250 of the fixed device performs a call function. In step 203, the CPU 250 of the fixed apparatus checks whether the talk level increase command data is received through the antenna and the RF transmitter / receiver 260 and the third amplifier 270, and proceeds to step 204 when the talk level increase command data is not received. In step 204, the CPU 250 maintains the trunk line call at the current call level and proceeds to step 206. However, when the talk level increase command data is received, the process proceeds to step 205 where the CPU 250 outputs the talk level gain control signal to control the gain of the reception amplifier in the third amplifier 270. Then, the gain of the receiving amplifier in the third amplifier 270 is increased to amplify the voice signal transmitted to the voice processing unit 300 to be transmitted to the telephone line. Thus, the receiving party can hear a higher level of the received voice signal. In step 206, if it is determined that the call has ended, if the call is not ended, the process returns to step 202 to continue the call function.

As described above, the present invention increases the talk level from the portable device to the fixed device without increasing the transmission voice signal by increasing the gain of the portable device when the call sensitivity is not good at the other side during the call from the wireless telephone to the portable device. By transmitting the command data to increase the transmission gain in the fixed device to transmit a larger voice signal is transmitted to reduce the current consumption of the battery mounted on the portable device has the advantage that the battery can be used for a long time.
