Apparatus and method for deleting a text message received in a mobile communication terminal

Abstract

Provided is an apparatus for deleting a text message received in a mobile communication terminal including an information detecting unit for detecting deletion time information from the received text message; a time checking unit for checking whether the deletion time arrives; and a deleting unit for deleting the received text message at the deletion time. The deletion time information is generated when the text message is generated by a calling side mobile communication terminal, is transmitted, and then is inserted as a predetermined tag into a CHARi field of a user data subparameter, from among subparameters of the bearer data parameter of the transport layer in the short message service data burst message structure. Otherwise, the deletion time information is included in a validity period subparameter, or is detected in a newly added subparameter. The apparatus may allow a selected message to be automatically deleted.

1 . An apparatus for deleting a text message received in a mobile communication terminal, the apparatus comprising: 
 an information detecting unit for detecting deletion time information from a subparameter newly added to a bearer data parameter of a transport layer in a short message service data burst message structure of the received text message;    a time checking unit for checking whether the deletion time arrives; and    a deleting unit for deleting the received text message at the deletion time.    
   
   
       2 . The apparatus as claimed in  claim 1 , wherein the deletion time information is generated when the text message is generated and transmitted by a calling side mobile communication terminal.  
   
   
       3 . The apparatus as claimed in  claim 1 , further comprising a memory for storing the received text message, wherein the deleting unit deletes the received text message from the memory at the deletion time.  
   
   
       4 . A method for deleting a text message received in a mobile communication terminal, the method comprising the steps of: 
 a) detecting deletion time information from a subparameter newly added to a bearer data parameter of a transport layer in a short message service data burst message structure of the received text message;    b) checking whether the deletion time arrives according to the deletion time information; and    c) deleting the received text message when the deletion time arrives.    
   
   
       5 . The method as claimed in  claim 4 , wherein the deletion time information is generated when the text message is generated and transmitted by a calling side mobile communication terminal.  
   
   
       6 . The method as claimed in  claim 4 , further comprising a step of storing the received text message in a memory unit, and the received text message is deleted from the memory when the deletion time has arrived.
