That is, a gain for the volume input and output through the speaker 70 or the microphone 80 is set according to the set call mode so that the volume according to the setting is input and output at a predetermined level for all calls.

For example, when the call mode is set to the silver mode, the mobile communication terminal increases the gain of the first amplifier 32a to increase the volume of the voice output through the speaker 70, and the second The gain of the amplifier 32b is lowered to reduce the volume input through the microphone 80.

FIG. 5 is a flowchart illustrating a call mode setting method of the mobile communication terminal according to the present invention. 6 is a flowchart illustrating a volume control method according to ambient noise of a mobile communication terminal according to the present invention.

As illustrated in FIG. 4, the mobile communication terminal controls the volume input and output according to the call number or the call ID (CID) of the call receiver or the sender.

When a call is received or originated, it is determined whether the call mode is set by checking a phone number or a call ID (CID) for the call originator or the receiver. (S1 to S3)

That is, when the call is received or originated, the phone number or call ID of the call counterpart is checked, and the call mode is determined for the corresponding phone number or call ID from the phonebook data stored in the memory.

Here, when the call mode is not set, the mobile communication terminal allows a call to be made without a separate volume control.

At this time, if a key input is detected during a call, the call mode is set according to the input key. For example, if a side key is input during a call, the call mode is switched to silver mode or child mode according to the up and down side key setting. (S4, S5)

In this case, the call mode may be switched based on preset data, and when the call mode is switched, the mobile communication terminal calls data of a selected input call mode and generates a gain control signal according to the volume of the speaker or the microphone. Adjust.

Here, the mobile communication terminal is capable of controlling the volume input and output by applying the generated gain control signal to an amplifier connected to the speaker or the microphone to amplify the audio signal input and output.

On the other hand, when the call mode is set for the telephone number or call ID (CID) of the incoming or outgoing call, the call mode of the mobile communication terminal is switched according to the set call mode data when the call is connected. (S6)

That is, the volume of the input and output is controlled by generating a gain control signal according to the set call mode data and applying the gain control signal to the amplifier for amplifying the audio signal input and output through the speaker or the microphone. (S7)

In this case, when the call mode is set as described above, the call mode is automatically switched according to the call reception and reception, and the volume can be adjusted. Also, even when the call mode is set, the call mode can be set manually according to the key input.

That is, when the call mode is set, the mobile communication terminal may be automatically or manually set to the call mode according to whether the automatic switching is set. When the call mode is set manually, the mobile communication terminal switches to the set call mode when a key input is detected during a call. Will be.

According to the call mode set as described above, a voice is inputted and transmitted, and a received call is output.

On the other hand, in the second embodiment of the mobile communication terminal, it is possible to control the volume of the mobile communication terminal itself regardless of the call receiver or caller at the time of call reception.

As illustrated in FIG. 5, when call mode setting data is input (S11), a call mode of the mobile communication terminal is set.

According to the set call mode, the volume of the input / output through the speaker or the microphone is variably controlled. (S12)

At this time, the mobile communication terminal is connected to the speaker or microphone to amplify the audio signal output to the speaker and to control the gain of the amplifier to amplify and output the audio signal input from the microphone to adjust the volume input and output . (S13)

When the call mode is set as described above and the call is received or transmitted, the gain of the amplification unit is controlled according to the set call mode to adjust the volume of the voice transmitted and received during the call. (S14, S15)

For example, if the call mode is set to silver mode, the voice input through the microphone decreases the gain, and the voice output through the speaker increases the gain, thereby increasing the amplification rate. Amplify so that you can hear louder.

In addition, by reducing the gain of the microphone as described above in the case where the level of the input voice is increased due to the weak hearing, it is possible to prevent the voice of an excessively large level from being transmitted to the call counterpart.

On the other hand, the operating method of the first and second embodiments of the mobile communication terminal can control the volume input and output according to the ambient noise as shown in FIG.

When a call is received or sent, the sound of surroundings is sensed in addition to the voice input and output (S21). (S22)

At this time, the noise level is determined according to the level of the ambient sound input (S23) and the input / output volume of the speaker or the microphone is controlled according to the determination result. (S24)

That is, when the ambient noise is high, the amplification rate of the voice output through the speaker is increased, and the amplification rate of the voice input through the microphone is reduced to prevent the input of the noise and the voice transmission power is improved even in the noise. .

The configuration of a mobile communication system according to the present invention is as follows. In this case, the mobile communication terminal of the mobile communication system is the same as described above, and the detailed description is omitted below. In addition to the above-described first and second embodiments, the mobile communication terminal of the mobile communication system includes a mobile communication terminal that cannot set the call mode itself.

The database 130 stores information on a plurality of mobile communication terminals MS01 and MS02 connected and call mode data set by the mobile communication terminal. Here, the call mode data is data set to amplify or reduce the level of a voice signal transmitted when a call is connected to a specific mobile communication terminal.

In this case, call mode data registered in the database 130 may be arbitrarily registered through the communication system or the mobile communication service connection of the mobile communication terminals MS01 and MS02.

Here, the main control unit 100 performs authentication according to the mobile communication terminals MS01 and MS02 when connected to the communication system or mobile communication service, and allows the input data to be registered in the database 130. .

When the call control signal is received, the decision controller 110 analyzes the call signal to determine information of the caller or the receiver, and sets a call mode from the database 130 according to the call ID of the caller or the receiver. Determine if it is.

In this case, when the call mode for the call ID (CID) is set, the decision controller 110 calls the corresponding data and applies the data to the signal processor 120.

In addition, the determination controller 110 determines a call ID (CID) with respect to the received call signal, and determines a rate plan of the call ID (CID).

Here, the decision controller 110 applies a control signal to the signal processor 120 when the call plan of the call ID is a call plan that requires a call mode setting.

Here, the signal processor 120 converts a call signal transmitted and received according to a control signal applied from the decision controller 110 and a voice signal to be transmitted to the corresponding mobile communication terminal.

That is, in the mobile communication system, when the first mobile communication terminal MS01 and the second mobile communication terminal MS02 are connected by a call, at least one of the first mobile communication terminal or the second mobile communication terminals MS01 and MS02. When the call mode is registered and registered in the above mobile communication terminal, the level of the voice signal transmitted to the mobile communication terminal in which the call mode is registered is converted and transmitted.

In addition, the mobile communication system is the level of the voice signal transmitted to the mobile communication terminal when at least one or more of the first mobile terminal or the second mobile communication terminal (MS01, MS02) is subscribed to a specific plan The transmission is changed according to the above plan.

For example, as shown in FIG. 9, when the first mobile communication terminal MS01 and the second mobile communication terminal MS02 are connected to each other and a voice signal is transmitted and received, the first mobile communication terminal transmits the voice signal. When the communication mode is set to increase the level of the signal and decrease the level of the received voice signal, the voice signal transmitted from the first mobile communication terminal MS01 is transmitted to the switching center through the base station, and the exchange The station determines the call ID of the first mobile communication terminal MS01 and retrieves call mode data from the database.

When the call mode is designated as described above, the switching center changes the level of the voice signal and transmits the level to the second mobile communication terminal MS02. In addition, the voice signal transmitted from the second mobile communication terminal MS02 to the first mobile communication terminal MS01 is reduced in level so as to be transmitted.

Here, even when the call mode is set such that the level of the received voice signal is increased and the level of the transmitted voice signal is decreased, the level of the received and received voice signal is changed. Will be sent.
