The present invention relates to a method for automatically setting a volume of a wireless communication terminal, and more particularly, by inserting a transmit / receive volume value into a call connection message transmitted during a call connection in a wireless communication terminal, a transmit / receive volume value of a receiving terminal. A method for automatically setting a volume of a wireless communication terminal for receiving, by a calling terminal, automatically adjusting a sending / receiving volume of a calling terminal so that a user does not need to adjust a sending / receiving volume directly. will be.

In the present invention, the wireless communication terminal is a mobile communication terminal, a personal communication service (PCS) terminal, a personal digital assistant (PDA), a smart phone, a next generation mobile communication (IMT-2000) terminal, a wireless LAN terminal and the like through wireless communication Refers to a portable wireless communication terminal capable of transmitting and receiving text and image data.

In general, during a call to a wireless communication terminal, the volume control is set by the user pressing a key of a key input unit (for example, a side key) directly. A conventional volume adjustment process of adjusting a volume by pressing a key will be described.

1 is a block diagram showing a volume control device of a conventional wireless communication terminal.                         

As shown in FIG. 1, the volume adjusting device recovers a compressed audio signal from an RF signal and outputs the signal as a PCM signal PCMin, and a digitally modulated PCM signal. After amplifying and filtering the signal, it is modulated into an analog signal and output to the speaker 120, and the codec 110 outputs an audio signal input from the microphone MIC 130 as a PCM signal PCMout. do.

The codec 110 includes a variable output amplifier 111 for amplifying the PCM modulated signal PCMin according to a gain set by a user, a low pass filter (LPF) 112 for lowpass filtering the amplified signal, A D / A converter 113 for converting the low pass filtered signal into an analog signal and outputting the analog signal to the speaker 120, and an A / D converter 114 for converting an audio signal input from the microphone 130 into a digital signal; And a band pass filter (BPF) 115 for filtering only the desired band of the digitally converted audio signal, and amplifying the output of the band pass filter 115 with a gain set by the user to output the PCM signal to the vocoder 100. It is composed of a variable input amplifier 116.

The volume adjusting apparatus of the conventional wireless communication terminal as described above will be described with reference to FIG. 1.

First, when the vocoder 100 modulates a received counterpart audio signal into a PCM signal and outputs the codec 110, the codec 110 converts the PCM signal into an analog signal and then outputs the speaker 120 to the microphone 120. The signal input from the 130 is converted into a digital signal, and then the PCM signal is output to the vocoder 100.

To this end, the codec 110 includes a variable output amplifier 111, a low pass filter 112, a D / A converter 113, an A / D converter 114, a band pass filter 115, and a variable input amplifier 116. The variable output amplifier 111 adjusts the gain value according to the volume level set by the user and outputs the PCM signal PCMin input from the vocoder 100, and the low pass filter 112 gains the gain. The filtered PCM signal is output after low pass filtering, and the D / A converter 113 converts the low pass filtered signal into an analog signal and outputs the analog signal to the speaker 120 so that the other party's voice is reproduced by the speaker 120. Be sure to

At this time, the vocoder 100 outputs data for changing the gain value of the variable output amplifier 111 through the general-purpose input / output port GPIO to the codec 110.

In addition, the user audio signal input from the microphone 120 is converted into a digital signal by the A / D converter 114 of the codec 110 and then filtered by a band pass filter 115 to a desired band and then the variable input amplifier 116. The gain is adjusted by the input and input to the vocoder 100 as a PCM signal.

As described above, the conventional volume control device is a passive method in which a user directly inputs a key. When the user sets a volume size by inputting a key, the gain value of the variable output amplifier 114 according to the volume size set by the user is set. Will be adjusted.

However, in order to adjust the gain value, the register value of the codec 110 may be set through the GPIO (DIO) of the vocoder 100.

As such, the amplified signal is reproduced to the speaker 120 according to the set value. However, since there is no information on the strength of the signal from the codec 100, there is a problem in that the audio signal of the correct size cannot be provided to the receiver.                         

That is, when the volume level is adjusted to " 5 ", the audio signal of level " 5 " However, in the wireless situation, it may be heard at level "2" or "3" depending on the situation of the other party.

This is because the audio signal different from the level set according to the situation of the other party is reproduced by the speaker 120 regardless of the level setting value of the terminal, there is a problem that can not play the audio signal of the other party constantly.

In this way, if there is a situation in which the other party (or the user) on the call cannot speak loudly or the phone state is not good and there are few audio signals transmitted, the user can only hear a small voice signal. Of course, it is possible to increase the strength of the signal received during the call, but it is very cumbersome to adjust the volume manually when received.

The present invention has been proposed to solve the above problems, and when a call is connected, the calling terminal receives the sending / receiving volume value of the receiving terminal, and transmits / receives the calling terminal according to the received sending / receiving volume value. It is an object of the present invention to provide a method for automatically setting a volume of a wireless communication terminal for automatically adjusting a volume without adjusting a volume by using a direct key by automatically adjusting a received volume value.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention.

And a display unit (LCD) 207 for displaying a short message, a multimedia message, schedule information, and the like according to the control of the operation / control unit 204, and driving and controlling the wireless communication terminal. There is an arithmetic / control unit 204 which controls the automatic volume setting function and controls various configurations. In addition, the wireless communication terminal includes basic components (not shown) for wireless communication.

The function of each component of the wireless communication terminal for the automatic volume setting method is as follows.

The wireless transceiver 201 is controlled by the operation / control unit 204 and converts a signal output from the operation / control unit 204 into a wireless signal. In addition, the wireless transceiver 204 converts the radio signal received through the antenna into a desired signal and outputs it. In particular, the wireless transceiver 201 transmits an ORIGINATION MESSAGE, a page response message PAGE RESPONSE MESSAGE to a base station, and a page message (GENERAL PAGE MESSAGE) sent from the base station, and a command message. ORDER MESSAGE) and the like.

On the other hand, the storage unit 202 stores the operation program and system program of the control unit 204, the operation program or system program is usually stored in the ROM (ROM) area included and can be erased as necessary. Electrically erasable ROMs include EEPROM and flash memory. The storage unit 202 also includes a RAM for temporarily storing data generated during execution of various operation programs.

The operation / control unit 204 transmits the first call connection signal to the receiving terminal through the wireless transmitting / receiving unit 201, and voice / sound according to the call volume information (transmission / reception volume value) of the response signal received at the receiving terminal. The control signal is transmitted to the voice / sound output unit (speaker) 205 to adjust the volume of the terminal.                     

3 is a flowchart illustrating a method for automatically setting a volume in a wireless communication terminal according to the present invention.

To automatically set the volume, call volume information is inserted into a message transmitted and received between the calling terminal and the receiving terminal.

Here, the message MESSAGE means unit information or transmitted unit information written in a suitable language or code for delivery by a communication means. From the point of view of a computer or a communication network, a unit is a unit configured according to a strict rule and transmitted according to a predetermined rule (protocol) between a transmitting device and a receiving device.

A message consists of text consisting of one or more blocks, characters indicating start and end, control characters, headers generated by software (destination address, message type, etc.) and error checking information or synchronizing information. do.

According to the present invention, a field for inserting call volume information may be added to the message component to transmit / receive call volume information.

The message is classified into an ORIGINATION MESSAGE, a GENERAL PAGE MESSAGE, a PAGE RESPONSE MESSAGE, an ORDER MESSAGE, and the like.

ORIGINATION MESSAGE means a message or information transmitted from an originating party to a base station for call connection.

GENERAL PAGE MESSAGE means a message or information received from the base station by the base station and transmitted from the base station to the receiving side.

The page response message (PAGE RESPONSE MESSAGE) refers to a message or information transmitted back to the base station in order to inform the call state of the receiver in response to the page message received from the base station.

The command message (ORDER MESSAGE) means a message or information that the base station receives the page response message transmitted from the receiving side, and transmits to the calling side.

First, when the calling terminal sends an ORIGINATION MESSAGE for the call volume (301), the receiving terminal receives a page message (PAGE MESSAGE) from the base station (302), and the page response message (PAGE RESPONSE MESSAGE). Send to the base station (303,304). At this time, the page response message includes a field in which the currently set transmit / receive volume value of the terminal is inserted, and inserts the transmit / receive volume value into the page response message and transmits it.

Here, the transmit / receive volume value indicates the level of the dial tone and the reception tone set in the wireless communication terminal. That is, the volume of the outgoing / incoming call set in the wireless communication terminal is shown.

In general, the send / receive volume can be set in 4 stages, and the receive volume consists of “1st stage: -12dbm”, “2nd stage: -4dbm”, “3rd stage: 3dbm”, “4th stage: 9dbm” The transmission volume is composed of "Step 1: -8dbm", "Step 2: -2dbm", "Step 3: 3dbm", and "Step 4: 6dbm". Here, the higher the level means the louder the volume.

Then, when the command message (ORDER MESSAGE) sent from the base station is received to the calling terminal (305), the calling terminal reads the transmission / reception volume value of the received receiving terminal (306), the read transmission / reception The send / receive volume value of the calling terminal is adjusted according to the volume value, and set to suit the call volume of the receiving terminal (307).

For example, the sending / receiving volume value of the calling party varies according to the receiving / receiving volume value. That is, if the receiving volume at the receiving side is 1st stage, the transmitting volume of the calling party is set to 4th stage to compensate with the high transmission call volume for the low receiving call volume, so that the calling party and the receiving side can make a call at the appropriate calling volume. Will be.

Similarly, if the receiving volume of the receiving side is two stages, the sending volume of the calling party is set to three stages. If the receiving volume of the receiving side is three stages, the sending volume of the calling side is set to two stages. In step 4, the sender's transmission volume is set in step 1.

On the other hand, if the sender's transmit volume is one step, the receiver's receive volume is four steps; if the sender's send volume is two steps, the receiver's receive volume is three steps; The receiving volume of the receiving side is set in two stages, and the receiving volume of the receiving side is set in one stage if the transmitting volume of the calling side is four stages.

4 is a flowchart illustrating an embodiment of a method for automatically setting a volume in a base station according to the present invention.

First, when an originating message (ORIGINATION MESSAGE) is received from the calling terminal (401), the base station sends a page message (PAGE MESSAGE) to the receiving terminal (402).

Thereafter, a page response message (PAGE RESPONSE MESSAGE) is received from the receiving terminal (403). At this time, the transmit / receive volume value of the receiving terminal is inserted in the page response message.

Accordingly, the base station reads the transmit / receive volume value of the receiver terminal from the page response message transmitted from the receiver terminal (404), inserts the read / receive volume value into the command message (ORDER MESSAGE) (405). It transmits to the calling terminal (406).

5 is a flowchart illustrating an embodiment of a method for automatically setting a wireless communication terminal volume according to the present invention.

First, when the originating terminal sends an outgoing message (ORIGINATION MESSAGE) that attempts to make a call connection (501), the base station sends a page message (PAGE MESSAGE) to the receiving terminal (502).

Thereafter, the receiving terminal sends a page response message (PAGE RESPONSE MESSAGE) to the base station in order to inform the calling party of the available call state (503).

In this case, the TX VOLUME and RX VOLUME fields are additionally included in the page response message, so that the transmit / receive volume values of the receiving terminal are inserted in the TX VOLUME and RX VOLUME fields.

As the page response message is sent, the base station extracts the TX VOLUME and RX VOLUME values inserted in the page response message, and transmits the TX VOLUME and RX VOLUME values to the calling terminal. It is inserted into the RX VOLUME field and transmitted to the calling terminal (504).

Subsequently, when a command message is sent from the base station and transmitted to the calling terminal, the calling terminal extracts TX VOLUME and RX VOLUME values of the received message through the operation / control unit 204 and performs voice / sound by TX VOLUME value. Compensates the volume of the voice / sound output to the output unit 205, and compensates the volume of the voice or sound input to the voice / sound input unit 206 according to the RX VOLUME value, thereby making the voice / sound suitable for the receiving terminal. 505 is set to make a call.

That is, if the receiving volume TX VOLUME of the receiving terminal is low, the receiving volume RX VOLUME of the calling terminal is increased, and if the receiving volume of the receiving terminal is low, the calling volume of the calling terminal is increased.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

As described above, the present invention automatically adjusts the sending / receiving volume of the calling party according to the sending / receiving volume of the receiving party, thereby reducing the inconvenience of the user adjusting the sending / receiving volume using a direct key during a call. It is convenient in that it is effective in that the caller and the receiver can always talk at the appropriate call volume.
