Herein, the memory  110  may be plural in number. 
         [0034]    Each component will be described below in detail. 
         [0035]    The memory  110  includes a program storage unit  111  for storing a program for controlling an operation of the electronic device  100  and a data storage unit  112  for storing data generated during the program is executed. For example, the program storage unit  111  includes a call handling program  113 , a communication program  114 , a Graphic User Interface (GUI) program  115 , and at least one application program  116 . Herein, the program included in the program storage unit  111  is a group of instructions, and may be expressed as an instruction set. 
         [0036]    The call handling program  113  includes at least one software component for processing a reception call. For example, if the call reception is sensed by the communication program  114 , the call handling program  113  confirms information of the received call. If a call rejection message is received, the rejection message is transmitted to a call sender under the control of the call handling program  113 . In this case, the call handling program  113  provides control to display the call rejection information. In addition, the call handling program  113  may provide control to periodically display the call rejection information. If the call reception is sensed by the communication program  114 , the call handling program  113  may determine to connect to the received call. 
         [0037]    The communication program  114  includes at least one software component for performing voice communication and data communication via the communication unit  170 . For example, the communication program  114  controls a call received via the communication unit  170 . If the rejection message is selected by the call handling program  113 , the call rejection message may be transmitted via the communication unit  170  under the control of the communication program  114 . If a call connection is determined by the call handling program  113 , the communication program  114  may control the call connection to the call sender. 
         [0038]    The GUI program  115  includes at least one software component for providing a graphic user interface on the display unit  150 . For one example, the GUI program  115  provides control to display call rejection information determined by the call handling program  113 . For another example, the GUI program  115  may provide control to display a missed call icon and a call rejection icon. 
         [0039]    The application program  116  includes a software component for at least one application installed in the electronic device  100 . 
         [0040]    The processor unit  120  includes a memory interface  121 , at least one processor  122 , and a peripheral device interface  123 . Herein, the memory interface  121 , the at least one processor  122 , and the peripheral device interface  123  included in the processor unit  120  may be integrated as at least one integrated circuit or may be implemented as separate components. 
         [0041]    The memory interface  121  controls an access to the memory  110  for a component such as the processor  122  or the peripheral device interface  123 . 
         [0042]    The peripheral device interface  123  controls a connection between an input/output peripheral device of the electronic device  100  and the processor  122  and the memory interface  121 . 
         [0043]    The processor  122  controls the electronic device  100  to provide various multimedia services by using at least one software program. In this case, the processor  122  executes at least one program stored in the memory  110  to provide a service according to the program. For example, the processor  122  can be configured as illustrated in  FIG. 2  to display call rejection information by executing the call handling program  113 . 
         [0044]    The audio processor  130  provides an audio interface between the user and the electronic device  100  via a speaker  131  and a microphone  132 . 
         [0045]    The input/output controller  140  provides an interface between the peripheral device interface  123  and an input/output device such as the display unit  150  and the input unit  160 . 
         [0046]    The display unit  150  displays status information of the electronic device  100 , a character input by the user, a moving picture, a still picture, and the like. For one example, the display unit  150  displays the call rejection information under the control of the GUI program  115 . For another example, the display unit  150  may display the missed call icon and the call rejection icon under the control of the GUI program  115 . 
         [0047]    If the display unit  150  includes a touch screen, the display unit  150  may further include a touch input unit for providing information on a touch sensed by using the touch panel to the processor unit  120  via the input/output controller  140 . 
         [0048]    The input unit  160  provides input data generated by a user&#39;s selection to the processor unit  120  via the input/output controller  140 . For example, the input unit  160  may include control buttons for the control of the electronic device  100 . For another example, the input unit  160  may include a key pad for receiving data input from the user. 
         [0049]    The communication unit  170  includes at least one software component for performing a communication function for voice communication and data communication. For example, the communication unit  170  provides call information to the communication program  114  upon sensing of the call reception. For another example, the communication unit  170  may transmit the call rejection message under the control of the communication program  114 . In this case, the communication unit may be divided into a plurality of communication sub-modules for supporting different communication networks. For example, although not limited thereto, the communication network may include one or more of a Global System for Mobile Communication (GSM) network, an Enhanced Data GSM Environment (EDGE) network, a Code Division Multiple Access (CDMA) network, a W-Code Division Multiple Access (W-CDMA) network, a Long Term Evolution (LTE) network, an Orthogonal Frequency Division Multiple Access (OFDMA) network, a Wireless Local Area Network (WLAN), a Bluetooth network, Near Field Communication (NFC), and the like. 
         [0050]      FIG. 2  is a block diagram of a processor according to an embodiment of the present disclosure. 
         [0051]    Referring to  FIG. 2 , the processor  122  includes a call handling processor  200 , a communication processor  210 , and a GUI processor  220 . 
         [0052]    The call handling processor  200  handles a call by executing the call handling program  113  of the program storage unit  111 . For example, upon sensing call reception by the communication processor  210 , the call handling processor  200  confirms information of the received call. If a call rejection message is selected, the call handling processor  200  provides control to transmit a rejection message to a call sender. In this case, the control of the call handling processor  200  provides control to display call rejection information. In addition, the call handling processor  200  provides control to periodically display the call rejection information. Upon sensing call reception by the communication processor  210 , the call handling processor  200  may determine to connect to the received call. 
         [0053]    The communication processor  210  executes the communication program  114  stored in the program storage unit  111  to perform voice communication and data communication via the communication unit  170 . For example, the communication processor  210  controls a call received via the communication unit  170 . If a rejection message is selected by the call handling processor  200 , the communication processor  210  can control the communication unit  170  to transmit a call rejection message. If a call connection is determined by the call handling processor  200 , the communication processor  210  may control the call connection to the call sender. 
         [0054]    The GUI processor  220  executes the GUI program  115  of the program storage unit  111  to provide a graphic user interface on the display unit  150 . For example, the GUI processor  220  provides control to display call rejection information determined by the call handling processor  200 . For another example, the GUI processor  220  may provide control to display a missed call icon and a call rejection icon. 
         [0055]    In the electronic device of the aforementioned embodiment, the call handling processor  200  is controlled to execute the call handling program  113  to display the call rejection information. 
         [0056]    In another embodiment, the electronic device may include another call handling unit including the call handling program  113 . 
         [0057]      FIG. 3A  is a flowchart illustrating a process for displaying call rejection information in an electronic device according to an embodiment of the present disclosure. 
         [0058]    Referring to  FIG. 3A , the electronic device transmits a rejection message for cell reception in operation  301 . For example, upon sensing of the call reception, the electronic device displays a call reception screen including a sender&#39;s name  901  and a sender&#39;s phone number  903  on the display unit  150  as illustrated in  FIG. 9A . If it is sensed that a call rejection message menu  905  is selected in the call reception screen by a user&#39;s manipulation, the electronic device displays a call rejection message list as illustrated in  FIG. 9B . 
         [0059]    As illustrated in  FIG. 9B , if a message  911  saying “I&#39;m in a meeting right now. I will call you later.” is selected by the user, the electronic device transmits the message  911  saying “I&#39;m in a meeting right now. I will call you later.” to a phone number included in the received call information (see  909 ). In this case, the electronic device ends the call reception. In addition, if the call rejection message menu is selected, the electronic device may transmit a pre-set rejection message. 
         [0060]    After transmitting the call rejection message, proceeding to operation  303 , the electronic device displays call rejection information on the display unit  150 . For example, as illustrated in  FIG. 9C , the electronic device displays call rejection information  935  on the display unit  150 . The call rejection information  935  includes a part  913  of the call rejection message transmitted to a call sender, a call rejection message transmission time  915 , a call sender&#39;s name  917 , a call sender&#39;s phone number  919 , and a call reception count  931 . In addition, as illustrated in  FIG. 9C , the electronic device may display a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. In this case, the electronic device may generate vibration and sound while displaying the call rejection information on the display unit  150 . 
         [0061]    Thereafter, the procedure of  FIG. 3  ends. 
         [0062]    As described above, the electronic device transmits the rejection message for the received call. In this case, the rejection message is configured either in a text form or in a voice form. For example, if the rejection message is configured in the text form, the electronic device transmits the rejection message to the call sender by using a short message service. 
         [0063]    For another example, if the rejection message is configured in voice form, the electronic device may temporarily connect a call to the call sender to transmit a voice message for the rejection. When transmission of the voice message is complete, the call connection to the call sender is finished. 
         [0064]    For another example, if the rejection message is configured in voice form, the electronic device may transmit a voice message for the rejection through an additional control channel in addition to the call connection. 
         [0065]    For another example, the electronic device may transmit index information for rejection message transmission to an additional server. In this case, the rejection message configured with at least one of a voice or a text corresponding to the index information is transmitted to the call sender. 
         [0066]    As described above, each of the operations for displaying the call rejection information in the electronic device may be configured by using a means for displaying the call rejection information in the electronic device as illustrated in  FIG. 3B . 
         [0067]      FIG. 3B  illustrates a structure of an electronic device for displaying call rejection information according to an embodiment of the present disclosure. 
         [0068]    Referring to  FIG. 3B , the electronic device includes a first means  305  for transmitting a rejection message for call reception and a second means  307  for displaying call rejection information. 
         [0069]    The first means  305  transmits a rejection message for call reception. For example, upon sensing of the call reception, the electronic device displays a call reception screen including a sender&#39;s name  901  and a sender&#39;s phone number  903  on the display unit  150  as illustrated in  FIG. 9A . If it is sensed that a call rejection message menu  905  is selected in the call reception screen by a user&#39;s manipulation, the electronic device displays a call rejection message list as illustrated in  FIG. 9B . 
         [0070]    As illustrated in  FIG. 9B , if a message  911  saying “I&#39;m in a meeting right now. I will call you later.” is selected by the user, the electronic device transmits the message  911  saying “I&#39;m in a meeting right now. I will call you later.” to a phone number included in the received call information (see  909 ). In this case, the electronic device ends the call reception. In addition, if the call rejection message menu is selected, the electronic device may transmit a pre-set rejection message. 
         [0071]    The second means  307  displays call rejection information on the display unit  150 . For example, as illustrated in  FIG. 9C , the electronic device displays call rejection information  935  on the display unit  150 . The call rejection information  935  includes a part  913  of the call rejection message transmitted to a call sender, a call rejection message transmission time  915 , a call sender&#39;s name  917 , a call sender&#39;s phone number  919 , and a call reception count  931 . In addition, as illustrated in  FIG. 9C , the electronic device may display a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. In this case, the electronic device may generate vibration and sound while displaying the call rejection information on the display unit  150 . 
         [0072]    As described above, the electronic device transmits the rejection message for the received call. In this case, the rejection message is configured either in a text form or in a voice form. For example, if the rejection message is configured in the text form, the electronic device transmits the rejection message to the call sender by using a short message service. 
         [0073]    For another example, if the rejection message is configured in voice form, the electronic device may temporarily connect a call to the call sender to transmit a voice message for the rejection. When transmission of the voice message is complete, the call connection to the call sender is finished. 
         [0074]    For another example, if the rejection message is configured in voice form, the electronic device may transmit a voice message for the rejection through an additional control channel in addition to the call connection. 
         [0075]    For another example, the electronic device may transmit index information for rejection message transmission to an additional server. In this case, the rejection message configured with at least one of a voice or a text corresponding to the index information is transmitted to the call sender. 
         [0076]    As described above, the electronic device includes various means for displaying the call rejection information. In an embodiment, the various means for displaying the call rejection information in the electronic device may be configured as one means. 
         [0077]      FIG. 4  is a flowchart illustrating a process for displaying call rejection information in an electronic device in an idle state according to an embodiment of the present disclosure. 
         [0078]    Referring to  FIG. 4 , the electronic device is in an idle state in operation  401 , and determines whether call reception is sensed via the communication unit  170  in operation  403 . 
         [0079]    Upon sensing the call reception, proceeding to operation  405 , the electronic device displays information on the reception-sensed call on the display unit  150 . For example, the electronic device displays a sender&#39;s name  901  and a sender&#39;s phone number  903  on the display unit  150  as illustrated in  FIG. 9A . If a phone number of the reception-sensed call is not stored in a phonebook, the electronic device may display only the phone number and not the name. 
         [0080]    After displaying information on the call on the display unit  150 , proceeding to operation  407 , the electronic device determines whether a call rejection message menu is selected. For example, as illustrated in  FIG. 9A , the electronic device determines whether a call rejection message menu  905  is selected by a user&#39;s manipulation in a screen which displays the reception-sensed call. Herein, when a user of the electronic device cannot immediately respond to the reception-sensed call, the call rejection message indicates a means capable of reporting to the call sender that the call cannot be immediately responded. 
         [0081]    If the call rejection message menu is selected, proceeding to operation  409 , the electronic device transmits any one message selected by the user from the call rejection messages. For example, as illustrated in  FIG. 9B , if a message  911  saying “I&#39;m in a meeting right now. I will call you later.” is selected by the user, the electronic device transmits the message  911  saying “I&#39;m in a meeting right now. I will call you later.” to a phone number included in the received call information (see  909 ). In this case, the electronic device ends the call reception. In addition, if the call rejection message menu is selected, the electronic device may transmit a pre-set rejection message. 
         [0082]    After transmitting the call rejection message, proceeding to operation  411 , the electronic device displays the call rejection information on the display unit  150 . For example, as illustrated in  FIG. 9C , the electronic device displays call rejection information  935  on the display unit  150 . The call rejection information  935  includes a part  913  of the call rejection message transmitted to a call sender, a call rejection message transmission time  915 , a call sender&#39;s name  917 , a call sender&#39;s phone number  919 , and a call reception count  931 . In addition, as illustrated in  FIG. 9C , the electronic device may display a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. In an embodiment, the electronic device may generate vibration and sound while displaying the call rejection information on the display unit  150 . 
         [0083]    If the call rejection message menu is not selected or if the call rejection message is not selected after the call rejection message menu is selected, proceeding to operation  413 , the electronic device determines whether the call reception is finished. 
         [0084]    If the call reception is not finished, returning to operation  405 , the electronic device continues to display information on the received call on the display unit  150  as illustrated in  FIG. 9A . If the call rejection message is not selected in a state in which the call rejection message menu is selected, the electronic device may continue to display the call rejection message selection screen as illustrated in  FIG. 9B . 
         [0085]    If the call reception is finished, proceeding to operation  415 , the electronic device displays a missed call icon on the display unit  150 . For example, the electronic device displays missed call icons  927  and  929  on the display unit  150  as illustrated in  FIG. 9D . In this case, if it is sensed that the user selects the missed call icon  927  displayed on the display unit  150 , as illustrated in  FIG. 9D , the electronic device may display a cell reception end time  915 , a call rejection message transmission time  915 , a call sender&#39;s name  917 , a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. 
         [0086]    Thereafter, the procedure of  FIG. 4  ends. 
         [0087]    As described above, the electronic device transmits the rejection message for the received call. In this case, the rejection message is configured either in text form or in voice form. For example, if the rejection message is configured in text form, the electronic device transmits the rejection message to the call sender by using a short message service. 
         [0088]    For another example, if the rejection message is configured in voice form, the electronic device may temporarily connect a call to the call sender to transmit a voice message for the rejection. When transmission of the voice message is complete, the call connection to the call sender is finished. 
         [0089]    For another example, if the rejection message is configured in voice form, the electronic device may transmit a voice message for the rejection through an additional control channel in addition to the call connection. 
         [0090]    For another example, the electronic device may transmit index information for rejection message transmission to an additional server. In this case, the rejection message configured with at least one of a voice or a text corresponding to the index information is transmitted to the call sender. 
         [0091]      FIG. 5  is a flowchart illustrating a process for displaying call rejection information in an electronic device during a call according, to an embodiment of the present disclosure. 
         [0092]    Referring to  FIG. 5 , while the line is busy in operation  501 , the electronic device determines whether cell reception is sensed in operation  503 . 
         [0093]    Upon sensing the call reception, proceeding to operation  505 , the electronic device displays information on the reception-sensed call on the display unit  150 . For example, the electronic device displays a sender&#39;s name  901  and a sender&#39;s phone number  903  on the display unit  150  as illustrated in  FIG. 9A . If a phone number of the reception-sensed call is not stored in a phonebook, the electronic device may display only the phone number and not the name. 
         [0094]    After displaying information on the call on the display unit  150 , proceeding to operation  507 , the electronic device determines whether a call rejection message menu is selected. For example, as illustrated in  FIG. 9A , the electronic device determines whether the call rejection message menu  905  is selected by a user&#39;s manipulation in a screen which displays the reception-sensed call. Herein, when a user of the electronic device cannot immediately respond to the reception-sensed call, the call rejection message indicates a means capable of reporting to the call sender that the call cannot be immediately responded. 
         [0095]    If the call rejection message menu is selected, proceeding to operation  509 , the electronic device transmits any one message selected by the user from the call rejection messages. For example, as illustrated in  FIG. 9B , if a message  911  saying “I&#39;m in a meeting right now. I will call you later.” is selected by the user, the electronic device transmits the message  911  saying “I&#39;m in a meeting right now. I will call you later.” to a phone number included in the received call information (see  909 ). In this case, the electronic device ends the call reception. In addition, if the call rejection message menu is selected, the electronic device may transmit a pre-set rejection message. 
         [0096]    After transmitting the call rejection message, proceeding to operation  511 , the electronic device determines whether the call is finished. 
         [0097]    If the call is finished, proceeding to operation  513 , the electronic device displays the call rejection information on the display unit  150 . For example, as illustrated in  FIG. 9C , the electronic device displays call rejection information  935  on the display unit  150 . The call rejection information  935  includes a part  913  of the call rejection message transmitted to a call sender, a call rejection message transmission time  915 , a call sender&#39;s name  917 , a call sender&#39;s phone number  919 , and a call reception count  931 . In addition, as illustrated in  FIG. 9C , the electronic device may display a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. In this case, the electronic device may generate vibration and sound while displaying the call rejection information on the display unit  150 . 
         [0098]    If the call rejection message menu is not selected or if the call rejection message is not selected after the call rejection message menu is selected, proceeding to operation  515 , the electronic device determines whether the call reception is finished during the call. 
         [0099]    If the call reception is not finished during the call, returning to operation  505 , the electronic device continues to display information on the received call on the display unit  150  as illustrated in  FIG. 9A . If the call rejection message is not selected in a state in which the call rejection message menu is selected, the electronic device may continue to display the call rejection message selection screen as illustrated in  FIG. 9B . 
         [0100]    If the call reception is finished, proceeding to operation  517 , the electronic device displays a missed call icon on the display unit  150 . For example, the electronic device displays missed call icons  927  and  929  on the display unit  150  as illustrated in  FIG. 9D . 
         [0101]    After displaying the missed call icon, proceeding to operation  511 , the electronic device confirms whether the call is finished. After the call is finished, if the user selects the missed call icon  927  displayed on the display unit  150 , as illustrated in  FIG. 9D , the electronic device may display a cell reception end time  915 , a call rejection message transmission time  915 , a call sender&#39;s name  917 , a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. 
         [0102]    Thereafter, the procedure of  FIG. 5  ends. 
         [0103]    As described above, the electronic device transmits the rejection message for the received call. In this case, the rejection message is configured either in text form or in voice form. For one example, if the rejection message is configured in text form, the electronic device transmits the rejection message to the call sender by using a short message service. 
         [0104]    For another example, if the rejection message is configured in voice form, the electronic device may temporarily connect a call to the call sender to transmit a voice message for the rejection. When transmission of the voice message is complete, the call connection to the call sender is finished. 
         [0105]    For another example, if the rejection message is configured in voice form, the electronic device may transmit a voice message for the rejection through an additional control channel in addition to the call connection. 
         [0106]    For another example, the electronic device may transmit index information for rejection message transmission to an additional server. In this case, the rejection message configured with at least one of a voice or a text corresponding to the index information is transmitted to the call sender. 
         [0107]      FIG. 6  is a flowchart illustrating a process for periodically displaying call rejection information in an electronic device in an idle state according to an embodiment of the present disclosure. 
         [0108]    Referring to  FIG. 6 , the electronic device is in an idle state in operation  601 , and determines whether call reception is sensed via the communication unit  170  in operation  603 . 
         [0109]    Upon sensing the call reception, proceeding to operation  605 , the electronic device displays information on the reception-sensed call on the display unit  150 . For example, the electronic device displays a sender&#39;s name  901  and a sender&#39;s phone number  903  on the display unit  150  as illustrated in  FIG. 9A . If a phone number of the reception-sensed call is not stored in a phonebook, the electronic device may display only the phone number and not the name. 
         [0110]    After displaying information on the call on the display unit  150 , proceeding to operation  607 , the electronic device determines whether a call rejection message menu is selected. For example, as illustrated in  FIG. 9A , the electronic device determines whether the call rejection message menu  905  is selected by a user&#39;s manipulation in a screen which displays the reception-sensed call. Herein, when a user of the electronic device cannot immediately respond to the reception-sensed call, the call rejection message indicates a means capable of reporting to the call sender that the call cannot be immediately responded. 
         [0111]    If the call rejection message menu is selected, proceeding to operation  609 , the electronic device transmits any one message selected by the user from the call rejection messages. For example, as illustrated in  FIG. 9B , if a message  911  saying “I&#39;m in a meeting right now. I will call you later.” is selected by the user, the electronic device transmits the message  911  saying “I&#39;m in a meeting right now. I will call you later.” to a phone number included in the received call information (see  909 ). In this case, the electronic device ends the call reception. In addition, if the call rejection message menu is selected, the electronic device may transmit a pre-set rejection message. 
         [0112]    After transmitting the call rejection message, proceeding to operation  611 , the electronic device determines whether a period for displaying call rejection information arrives. Herein, the period for displaying the call rejection information includes at least one of a period which is pre-set by a system or a period which is set by the user. 
         [0113]    At the arrival of the period for displaying the call information and the call rejection message, proceeding to operation  613 , the electronic device displays the call rejection information on the display unit  150 . For example, as illustrated in  FIG. 9C , the electronic device displays call rejection information  935  on the display unit  150 . The call rejection information  935  includes a part  913  of the call rejection message transmitted to a call sender, a call rejection message transmission time  915 , a call sender&#39;s name  917 , a call sender&#39;s phone number  919 , and a call reception count  931 . In addition, as illustrated in  FIG. 9C , the electronic device may display a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. In this case, the electronic device may generate vibration and sound while displaying the call rejection information on the display unit  150 . 
         [0114]    If the call rejection message menu is not selected or if the call rejection message is not selected after the call rejection message menu is selected, proceeding to operation  615 , the electronic device determines whether the call reception is finished. 
         [0115]    If the call reception is not finished, returning to operation  605 , the electronic device continues to display information on the received call on the display unit  150  as illustrated in  FIG. 9A . If the call rejection message is not selected in a state in which the call rejection message menu is selected, the electronic device may continue to display the call rejection message selection screen as illustrated in  FIG. 9B . 
         [0116]    If the call reception is finished, proceeding to operation  617 , the electronic device displays a missed call icon on the display unit  150 . For example, the electronic device displays missed call icons  927  and  929  on the display unit  150  as illustrated in  FIG. 9D . In this case, if it is sensed that the user selects the missed call icon  927  displayed on the display unit  150 , as illustrated in  FIG. 9D , the electronic device may display a cell reception end time  915 , a call rejection message transmission time  915 , a call sender&#39;s name  917 , a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. 
         [0117]    Thereafter, the procedure of  FIG. 6  ends. 
         [0118]    As described above, the electronic device transmits the rejection message for the received call. In this case, the rejection message is configured either in text form or in voice form. For example, if the rejection message is configured in text form, the electronic device transmits the rejection message to the call sender by using a short message service. 
         [0119]    For another example, if the rejection message is configured in voice form, the electronic device may temporarily connect a call to the call sender to transmit a voice message for the rejection. When transmission of the voice message is complete, the call connection to the call sender is finished. 
         [0120]    For another example, if the rejection message is configured in voice form, the electronic device may transmit a voice message for the rejection through an additional control channel in addition to the call connection. 
         [0121]    For another example, the electronic device may transmit index information for rejection message transmission to an additional server. In this case, the rejection message configured with at least one of a voice or a text corresponding to the index information is transmitted to the call sender. 
         [0122]      FIG. 7  is a flowchart illustrating a process for periodically displaying call rejection information in an electronic device during a call according to an embodiment of the present disclosure. 
         [0123]    Referring to  FIG. 7 , while the line is busy in operation  701 , the electronic device determines whether cell reception is sensed in operation  703 . 
         [0124]    Upon sensing the call reception, proceeding to operation  707 , the electronic device displays information on the reception-sensed call on the display unit  150 . For example, the electronic device displays a sender&#39;s name  901  and a sender&#39;s phone number  903  on the display unit  150  as illustrated in  FIG. 9A . If a phone number of the reception-sensed call is not stored in a phonebook, the electronic device may display only the phone number and not the name. 
         [0125]    After displaying information on the call on the display unit  150 , proceeding to operation  707 , the electronic device determines whether a call rejection message menu is selected. For example, as illustrated in  FIG. 9A , the electronic device determines whether the call rejection message menu  905  is selected by a user&#39;s manipulation in a screen which displays the reception-sensed call. Herein, when a user of the electronic device cannot immediately respond to the reception-sensed call, the call rejection message indicates a means capable of reporting to the call sender that the call cannot be immediately responded. 
         [0126]    If the call rejection message menu is selected, proceeding to operation  709 , the electronic device transmits any one message selected by the user from the call rejection messages. For example, as illustrated in  FIG. 9B , if a message  911  saying “I&#39;m in a meeting right now. I will call you later.” is selected by the user, the electronic device transmits the message  911  saying “I&#39;m in a meeting right now. I will call you later.” to a phone number included in the received call information (see  909 ). In this case, the electronic device ends the call reception. In addition, if the call rejection message menu is selected, the electronic device may transmit a pre-set rejection message. 
         [0127]    After transmitting the call rejection message, proceeding to operation  711 , the electronic device determines whether the call is finished. 
         [0128]    If the call is finished, proceeding to operation  713 , the electronic device determines whether a period for displaying call rejection information arrives. Herein, the period for displaying the call rejection information includes at least one of a period which is pre-set by a system or a period which is set by the user. 
         [0129]    At the arrival of the period for displaying the call information and the call rejection message, proceeding to operation  715 , the electronic device displays the received call information and the transmitted call rejection message on the display unit  150 . For example, as illustrated in  FIG. 9C , the electronic device displays call rejection information  935  on the display unit  150 . The call rejection information  935  includes a part  913  of the call rejection message transmitted to a call sender, a call rejection message transmission time  915 , a call sender&#39;s name  917 , a call sender&#39;s phone number  919 , and a call reception count  931 . In addition, as illustrated in  FIG. 9C , the electronic device may display a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. In this case, the electronic device may generate vibration and sound while displaying the call rejection information on the display unit  150 . 
         [0130]    If the call rejection message menu is not selected or if the call rejection message is not selected after the call rejection message menu is selected, proceeding to operation  717 , the electronic device determines whether the call reception is finished during the call. 
         [0131]    If the call reception is not finished during the call, returning to operation  705 , the electronic device continues to display information on the received call on the display unit  150  as illustrated in  FIG. 9A . If the call rejection message is not selected in a state in which the call rejection message menu is selected, the electronic device may continue to display the call rejection message selection screen as illustrated in  FIG. 9B . 
         [0132]    If the call reception is finished, proceeding to operation  719 , the electronic device displays a missed call icon on the display unit  150 . For example, the electronic device displays missed call icons  927  and  929  on the display unit  150  as illustrated in  FIG. 9D . 
         [0133]    After displaying the missed call icon, proceeding to operation  711 , the electronic device confirms whether the call is finished. After the call is finished, if the user selects the missed call icon  927  displayed on the display unit  150 , as illustrated in  FIG. 9D , the electronic device may display a cell reception end time  915 , a call rejection message transmission time  915 , a call sender&#39;s name  917 , a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. 
         [0134]    Thereafter, the procedure of  FIG. 7  ends. 
         [0135]    As described above, the electronic device transmits the rejection message for the received call. In this case, the rejection message is configured either in text form or in voice form. For example, if the rejection message is configured in text form, the electronic device transmits the rejection message to the call sender by using a short message service. 
         [0136]    For another example, if the rejection message is configured in voice form, the electronic device may temporarily connect a call to the call sender to transmit a voice message for the rejection. When transmission of the voice message is complete, the call connection to the call sender is finished. 
         [0137]    For another example, if the rejection message is configured in voice form, the electronic device may transmit a voice message for the rejection through an additional control channel in addition to the call connection. 
         [0138]    For another example, the electronic device may transmit index information for rejection message transmission to an additional server. In this case, the rejection message configured with at least one of a voice or a text corresponding to the index information is transmitted to the call sender. 
         [0139]      FIG. 8  is a flowchart illustrating a process for performing an event by using call rejection information in an electronic device according to an embodiment of the present disclosure. 
         [0140]    Referring to  FIG. 8 , the electronic device determines whether a period for displaying call rejection information arrives in operation  801 . Herein, the period for displaying the call rejection information includes at least one of a period which is pre-set by a system or a period which is set by the user. 
         [0141]    At the arrival of the period for displaying the call rejection information, proceeding to operation  803 , the electronic device drives a timer for determining a display duration time of the call rejection information. Herein, the display duration time of the call rejection information may be pre-set by a system or may be set by a user. 
         [0142]    After driving the timer, proceeding to operation  805 , the electronic device displays call rejection information on the display unit  150 . For example, as illustrated in  FIG. 9C , the electronic device displays call rejection information  935  on the display unit  150 . The call rejection information  935  includes a part  913  of the call rejection message transmitted to a call sender, a call rejection message transmission time  915 , a call sender&#39;s name  917 , a call sender&#39;s phone number  919 , and a call reception count  931 . In addition, as illustrated in  FIG. 9C , the electronic device may display a connection control menu  937  including a “connection” menu  921  for attempting a call connection to the call sender&#39;s phone number  919 , a “snooze” menu  923  for displaying the call rejection information again after a reference time elapses, and a “close” menu  925  for releasing the display of the call rejection information. In this case, the electronic device may generate vibration and sound while displaying the call rejection information on the display unit  150 . 
         [0143]    After displaying the call rejection information on the display unit  150 , proceeding to operation  807 , the electronic device determines whether an event for the connection control menu is generated. For example, as illustrated in  FIG. 9C , the electronic device determines whether at least one of the “connection” menu  921 , the “snooze” menu  923 , and the “close” menu  925  is selected from the connection control menu  937  including these menus. 
         [0144]    At the occurrence of the event for the connection control menu, proceeding to operation  809 , the electronic device determines whether it is the call connection event. For example, as illustrated in  FIG. 9C , the electronic device determines whether the “connection” menu  921  is selected for attempting a call connection to the call sender&#39;s phone number  919 . 
         [0145]    If it is the call connection event, proceeding to operation  811 , the electronic device attempts a call connection according to the call information. For example, as illustrated in  FIG. 9E , the call connection is attempted to the phone number  941  which is the same as the phone number  919  of the call sender illustrated in  FIG. 9C . In this case, the electronic device recognizes that the call rejection information is no longer displayed. 
         [0146]    Otherwise, if it is not the call connection event, proceeding to operation  813 , the electronic device determines whether it is a snooze event. For example, as illustrated in  FIG. 9C , the electronic device determines whether the “snooze” menu  923  is selected for displaying the call rejection information again after a reference time elapses. Herein, the snooze is for periodically displaying the call rejection information again if the display of the call rejection information is released by the timer, and a period of the snooze may be pre-set by a system or may be set by a user. 
         [0147]    If it is the snooze event, proceeding to operation  815 , the electronic device determines whether the snooze period arrives. 
         [0148]    At the arrival of the snooze period, returning to operation  803 , the electronic device drives the timer. 
         [0149]    Otherwise, if it is not the snooze event, proceeding to operation  817 , the electronic device determines whether it is the display end event for the call rejection information. For example, as illustrated in  FIG. 9C , the electronic device may display the “close” menu  925  for releasing the display of the call rejection information. 
         [0150]    Thereafter, the procedure of  FIG. 9  ends. 
         [0151]    In the aforementioned embodiment, the electronic device displays call rejection information for a call which transmits a call rejection message. 
         [0152]    In another embodiment, the electronic device may transmit the call rejection message even if call connection is performed. In this case, the electronic device may display call rejection information. 
         [0153]    As described above, since the electronic device displays the reception-rejected call information and the rejection message, the user of the electronic device can easily recognize the reception-rejected call. 
         [0154]    In addition, since the electronic device adds the call connection menu to the reception-rejected call information and the rejection message displayed on the display unit, there is an advantage in that the user of the electronic device can easily perform call connection for the reception-rejected call. 
         [0155]    While the present disclosure has been particularly shown and described with reference to 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 present disclosure as defined by the appended claims.
