       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to a method and an apparatus for controlling a sound volume in a mobile communication terminal. More particularly, the present invention relates to a method and an apparatus for controlling a receive volume according to a phone number. 
         [0004]    2. Description of the Related Art 
         [0005]    Mobile communication terminals, which allow users to communicate and exchange messages with other users on the move and which provide various services such as schedule management and games, have become a necessity for many of the users. 
         [0006]    The mobile communication terminal users talk over the phone according to their individual habits. For example, a user might speak into a microphone close to his/her mouth, speak into the microphone away from the mouth, talk with a loud voice, or talk with a small voice. Since the users speak over the phone according to their individual habits, a sound volume of people on the phone can vary according to a particular user. 
         [0007]    However, the mobile communication terminal outputs a sound signal received from another mobile communication terminal in a regular volume. Disadvantageously, the user of the mobile communication terminal needs to personally listen to the sound signal received from the other mobile communication terminal and manually increase or decrease the receive volume according to his/her preference or situation.

A set is defined as a non-empty set including at least one element. 
         [0024]    Exemplary embodiments of the present invention provide a technique for storing receive volume control information per phone number in a mobile communication terminal, and controlling the receive volume according to a phone number of the other mobile communication terminal when a call is made. 
         [0025]      FIG. 1  is a block diagram of a mobile communication terminal according to an exemplary embodiment of the present invention. 
         [0026]    Referring to  FIG. 1 , the mobile communication terminal includes a communication module  100 , a controller  110 , a voice processor  120 , a voice input and output unit  130 , a storage unit  140 , an input unit  150 , and a display unit  160 . The controller  110  includes a volume controller  112 . 
         [0027]    The communication module  100  processes signals transmitted and received over an antenna under the control of the controller  110 . In more detail, the communication module  100  up-converts a baseband signal output from the controller  110  into a radio frequency signal and sends the radio frequency signal over the antenna, down-converts a radio frequency signal received via the antenna into a baseband signal and outputs the baseband signal to the controller  110 . More particularly, the communication module  100  provides a voice signal received from another mobile communication terminal to the controller  110 . 
         [0028]    The controller  110  controls and processes operations of the mobile communication terminal. The controller  110 , including the volume controller  112 , controls and processes a function for controlling the volume of the output voice signal, according to a phone number of the other mobile communication terminal, during the phone call. 
         [0029]    More specifically, when the phone call is made, the volume controller  112  checks the phone number of the other mobile communication terminal and then determines whether receive volume control information (hereafter, referred to as volume information) of the phone number is pre-stored. When the volume information is pre-stored, the volume controller  112  adjusts the output volume of the voice signal received from the other mobile communication terminal using the pre-stored volume information. When the volume information is not pre-stored, the volume controller  112  controls to adjust the output volume of the voice signal received from the other mobile communication terminal according to basic volume information. Herein, the volume information includes at least one of a speaker volume, a receiver volume, an earphone volume, and a Bluetooth earphone volume. More than one type of volume information may be included for the same phone number, and the volume information for different types may be different. The volume controller  112  provides the voice processor  120  with the volume corresponding to the current voice output path of the mobile communication terminal in the pre-stored volume information. 
         [0030]    When a user&#39;s manipulation changes the volume in the communication with the other mobile communication terminal, the volume controller  112  controls to store and update information relating to the changed volume as volume information relating to the phone number of the mobile communication terminal. 
         [0031]    The voice processor  120  is referred to as a Coder-Decoder (CODEC) and processes the input and the output of the voice signal via the voice input and output unit  130 . For example, the voice processor  120  converts a digital voice signal fed from the controller  110  into an analog voice signal and sends the analog voice signal through the voice input and output unit  130 . The voice processor  120  converts the voice signal fed from the voice input and output unit  130  into a digital voice signal and provides the digital voice signal to the controller  110 . In particular, under the control of the volume controller  112  of the controller  110 , the voice processor  120  adjusts the volume of the voice signal and then provides the adjusted voice signal to the voice input and output unit  130 . For example, the voice processor  120  receives the voice signal and the volume information relating to the voice signal from the volume controller  112 , and amplifies the voice signal according to the volume information. 
         [0032]    The voice input and output unit  130  outputs the voice fed from the voice processor  120 , and receives and forwards the user&#39;s voice to the voice processor  120 . The voice input and output unit  130  may include at least one of a speaker, a receiver, earphones, and a microphone. Herein, the receiver represents a speaker for lower-power voice communication. 
         [0033]    The storage unit  140  stores programs and data for the operations of the mobile communication terminal. Under the control of the volume controller  112 , the storage unit  140  stores the volume information per phone number. For instance, referring to  FIG. 2 , the storage unit  140  maps and stores volume information of the speaker output SPK  210 , volume information of the receiver output RCV  220 , volume information of the earphone output EAR  230 , and volume information of the Bluetooth earphone output BT  240  information to the phone number  200 . In so doing, the storage unit  140  may store the volume information per phone number only for the phone numbers stored to a phonebook, or may do so for every phone number contacted. For example, the storage unit  140  may store the volume information per phone number to the phonebook, and also to an extra space for the phone numbers in a phone number recording region. 
         [0034]    The input unit  150  includes at least one input key or touch sensor, and provides data corresponding to the key or the touch of the user to the controller  110 . In particular, the input unit  150  receives the key input for changing the output volume of the voice signal received from the other mobile communication terminal, and provides the received key input to the controller  110 . 
         [0035]    The display unit  160  displays state information, a limited number of numerals and characters, videos, and still images generated in the operations of the mobile communication terminal. 
         [0036]      FIG. 3  is a flowchart of a volume control method in the mobile communication terminal according to an exemplary embodiment of the present invention. 
         [0037]    Referring to  FIG. 3 , when the phone call is connected to the other mobile communication terminal in step  301 , the mobile communication terminal sets the output path of the voice signal in step  303 . For instance, the mobile communication terminal determines which one of the speaker, the receiver, the earphones, and the Bluetooth earphones outputs the voice signal. 
         [0038]    Next, the mobile communication terminal checks the phone number of the other mobile communication terminal in step  305  and examines whether the phone number is pre-registered to the mobile communication terminal in step  307 . For example, the mobile communication terminal examines whether the phone number is pre-registered to the phonebook, or whether the phone number, which is not registered to the phonebook, is registered as a previous contact phone number. 
         [0039]    When the phone number is pre-registered to the mobile communication terminal, the mobile communication terminal determines whether the volume information of the phone number is stored in step  309 . For example, for the phone number  200 , the mobile communication terminal determines whether at least one of the volume information of the speaker output SPK  210 , the volume information of the receiver output RCV  220 , the volume information of the earphone output EAR  230 , and the volume information of the Bluetooth earphone output BT  240  information is stored as shown in  FIG. 2 . 
         [0040]    If it is determined in step  309  that the volume information for the phone number is not stored, the mobile communication terminal controls and sets the volume of the voice signal received from the other mobile communication terminal according to the preset basic volume information in step  313 , and then proceeds to step  315 . 
         [0041]    In contrast, if it is determined in step  309  that the volume information for the phone number is stored, the mobile communication terminal controls and sets the volume of the voice signal received from the other mobile communication terminal according to the stored volume information in step  311 , and then proceeds to step  315 . Herein, the mobile communication terminal determines the volume information corresponding to the voice output path set in step  303  in the volume information, and controls and sets the volume of the voice signal received from the other mobile communication terminal according to the volume information corresponding to the voice output path. 
         [0042]    Next, the mobile communication terminal outputs the voice amplified or adjusted to the set volume in step  315 , and determines whether the volume is changed by the user&#39;s key manipulation in step  317 . For example, the mobile communication terminal may determine whether one of two side keys for increasing and decreasing the volume is input. 
         [0043]    If it is determined that the volume is not changed by the user&#39;s key manipulation, the mobile communication terminal proceeds to step  321 . If it is determined that the volume is changed by the user&#39;s key manipulation, the mobile communication terminal outputs the voice in the changed volume and stores the changed volume information in step  319 . Herein, the mobile communication terminal stores and updates the set voice output path and the changed volume information in relation to the phone number of the other mobile communication terminal. For example, when the key for the volume increase of the side keys is input once, the mobile communication terminal may amplify the volume of the output voice by one level and store the volume information indicating that the volume for that phone number is set to one greater level. 
         [0044]    In step  321 , the mobile communication terminal checks whether the call with the other mobile communication terminal ends. If it is determined that the call does not end, the mobile communication terminal goes back to step  317 . If it is determined that the call ends, the mobile communication terminal finishes this process. 
         [0045]    As set forth above, the mobile communication terminal stores the information for controlling the receive volume per phone number, and controls the receive volume according to the phone number of the counterpart mobile communication terminal in the phone call. Therefore, there is no need to adjust the volume in every phone call in accordance with the voice volume of the counterpart user. 
         [0046]    While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents
