Method and communication terminal apparatus for displaying function in communication

Abstract

A method and communication terminal apparatus for displaying a function in communication is disclosed that includes a display unit, a memory unit for storing and managing operation information including an additional function information and a function list in communication provided by the communication terminal apparatus. A main processing unit automatically reads the function list in communication stored in the memory unit and displays the list on the display unit when an operation mode of the communication terminal apparatus changes from a communication waiting mode to a communication mode. In the communication terminal apparatus, when an operation mode of the communication terminal apparatus changes to a communication mode, a function list in communication stored in advance is automatically read and then displayed. Accordingly, in the communication terminal apparatus, a function in communication is automatically informed to a user, and therefore, users can use the function in communication more conveniently.

       2 . The communication terminal apparatus of  claim 1 , wherein the main processing unit displays the function list in communication in a type selected from among a text type and an icon type.  
   
   
       3 . The communication terminal apparatus of  claim 1 , wherein the main processing unit displays the function list in communication during a predetermined display time and deletes the function list on the display unit in communication after expiration of the predetermined display time.  
   
   
       4 . The communication terminal apparatus of  claim 1 , wherein the main processing unit periodically displays the function list in communication according to a predetermined display time interval.  
   
   
       5 . The communication terminal apparatus of  claim 1 , wherein the main processing unit further comprises an input unit for receiving a control command of a user and modifies the function list in communication on the basis of the control command of the user inputted through the input unit.  
   
   
       6 . The communication terminal apparatus of  claim 5 , wherein the main processing unit reads the additional function information stored in the memory unit in response to the user's command to add in-communication functions, provides the additional function information to the user, and adds a corresponding item to the function list in communication on the basis of information selected by the user.  
   
   
       7 . The communication terminal apparatus of  claim 5 , wherein the main processing unit deletes a corresponding item from the function list in communication in response to a command from the user to delete the item.  
   
   
       8 . The communication terminal apparatus of  claim 1 , wherein the function list in communication includes sending a self number.  
   
   
       9 . The communication terminal apparatus of  claim 1 , wherein the function list in communication includes sending a dual tone multi-frequency (DTMF).  
   
   
       10 . The communication terminal apparatus of  claim 1 , wherein the function list in communication includes a call shift.  
   
   
       11 . The communication terminal apparatus of  claim 1 , wherein the function list in communication includes a call holding.  
   
   
       12 . The communication terminal apparatus of  claim 1 , wherein the function list in communication includes a transmission sound interception.  
   
   
       13 . A method for displaying a function in communication of a communication terminal apparatus including a display unit, the method comprising the steps of: 
 when an operation mode of the communication terminal apparatus changes to a communication mode, automatically reading a stored function list in communication; and    displaying the function list in communication on the display unit.    
   
   
       14 . The method for displaying a function in communication of a communication terminal apparatus of  claim 13 , wherein the function list in communication is displayed in a type selected from among a text type or an icon type.  
   
   
       15 . The method for displaying a function in communication of a communication terminal apparatus of  claim 13  wherein the function list in communication is displayed during a predetermined display time and the function list in communication is deleted on the display unit after expiration of the predetermined display time.  
   
   
       16 . The method for displaying a function in communication of a communication terminal apparatus of  claim 13  wherein the function list in communication is periodically displayed according to a predetermined display time interval.  
   
   
       17 . The method for displaying a function in communication of a communication terminal apparatus of  claim 13 , further comprising a step of modifying the function list in communication according to a control command of a user.  
   
   
       18 . The method for displaying a function in communication of a communication terminal apparatus of  claim 17 , wherein the modifying step further comprises: 
 reading additional function information stored in advance in response to the user's command to add an additional function in communication and providing the additional function information to the user; and    adding a corresponding item to the function list in communication on the basis of information selected by the user.    
   
   
       19 . The method for displaying a function in communication of a communication terminal apparatus of  claim 18 , wherein a corresponding item is deleted from the function list in communication in response to a command from the user to delete the item.  
   
   
       20 . The method for displaying a function in communication of a communication terminal apparatus of  claim 13 , further comprising a step of performing a function selected by a user.  
   
   
       21 . The method for displaying a function in communication of a communication terminal apparatus of  claim 13 , further comprises performing the function selected by user in communication.
