Hereinafter, a process of searching for a call list and making a call using the earphone key according to the present invention will be described in detail with reference to FIGS. 2 and 3.

In step 300 of FIG. 3, the controller 200 determines whether an earphone key 236 is input from a user. If there is an input of the earphone key 236 from the user in step 300, the controller 200 proceeds to step 302. In step 302, the controller 200 outputs the phone number and name of the first call list in the recent call list as voice and proceeds to step 304. That is, when the first earphone key 236 is input, the controller 200 determines that the phone number of the first call list is selected from the recent call list, and outputs the selected phone number and name to the earphone speaker 234. If there is no name stored in the address book corresponding to the telephone number of the call list, only the telephone number is output as a voice. In addition, the control unit 200 informs that the start of the recent call list search, information on whether the telephone number of the first call list of the recent call list is the calling number or the receiving number, and the call time for the telephone number. Can be output by voice. In addition, the controller 200 may output the phone number and name to the display unit 206.

In step 304, the controller 200 determines whether an earphone key 236 is input within a preset time. If there is an input of the earphone key 236 within the preset time, the controller 200 proceeds to step 306, and otherwise ends. For example, assuming that the preset time is 10 seconds, if there is an input of the earphone key 236 within 10 seconds after outputting the phone number and name of the first call list in the recent call list as voice, the process proceeds to step 306. Otherwise exit.

In step 306, the controller 200 determines whether the number of times of input of the earphone key 236 is one time. If the number of inputs of the earphone key 236 is one time, the flow proceeds to step 308, and if not, the flow proceeds to step 310. In step 308, the control unit 200 makes a call to the phone number of the recent call list currently being output.

In step 310, the controller 200 determines whether the number of times of input of the earphone key 236 is two consecutive times. In this case, the number of key inputs being continuous means that the time between the key input and the key input is shorter than the preset time. For example, if the preset time is 0.5 seconds, two consecutive times means that there is a second keystroke within 0.5 seconds after the first keystroke, and three consecutive times means 0.5 seconds after the first keystroke. This means that the second key input is made within the third key input, and the third key input is made within 0.5 seconds after the second key input. If the number of inputs of the earphone key 236 is two consecutive times, the process proceeds to step 312. Otherwise, the process proceeds to step 314. In step 312, the control unit 200 outputs the phone number and name of the next recent call list as voice and proceeds to step 304. In addition, the controller 200 may output information about whether the telephone number is a calling number or a receiving number, and a call time for the telephone number as a voice.

In step 314, the controller 200 determines whether the number of times of inputting the earphone key 236 is three times in a row. If the number of times of input of the earphone key 236 is three consecutive times, the process proceeds to step 316. If the number of times of input of the earphone key 236 exceeds three consecutive times, the process proceeds to step 304. In step 316, the control unit 200 outputs the phone number and name of the previous recent call list as voice and proceeds to step 304. In addition, the controller 200 may output information about whether the telephone number is a calling number or a receiving number, and a call time for the telephone number as a voice.

For example, the terminal stores two recent call lists on the same day, the current time is 5 o'clock, and each call time and phone number is' 1 o'clock, 016-345-6789 'and' 3 o'clock. , 018-123-4567 '. In addition, it is assumed that the telephone number '016-345-6789', which is called at 1 o'clock, is the caller's number, and the telephone number '018-123-4567', which is called at 5 o'clock, is a missed reception number. At this time, the phone number of the first call list of the recent call list is '018-123-4567'. Therefore, when the earphone key 236 is pressed once, the announcement "Introduction to the recent call list" along with the announcement of the first call list in the recent call list 'calling number 018-123-4567 'Is output as voice. Thereafter, if the earphone key 236 is input twice in a row, the controller 200 outputs a voice message, 'the missed reception number 016-345-6789 at 5 o', indicating the telephone number of the next recent call list as a voice and the earphone key ( 236) Wait for input. Thereafter, if the earphone key 236 is input three times in a row, the controller 200 outputs a voice message “calling number 018-234-5678” indicating a phone number of the previous recent call list as a voice and the earphone key 236. Wait for input. Thereafter, if the earphone key 236 is input four times in a row, the controller 200 maintains the standby state, and proceeds to step 304 to determine whether the earphone key 236 is input. After that, if the earphone key 236 is input once, the phone number '018-123-4567' is currently output.

If the phone number of the recent call list stored in the terminal 220 is registered in the address book of the terminal 220, the name of the person corresponding to the phone number of the recent call list is output as a voice. For example, if the name 'Hong Gil-dong' corresponding to the telephone number '018-123-4567' called at 3:00 of the two recent call lists shown in the above example is stored in the address book of the terminal 220, the telephone number It outputs the name 'Hong Gil-dong' with '018-123-4567' as a voice. In addition, as described above, the phone number and name selected by the recent call list search may be output as voice and displayed on the screen of the terminal 220.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. For example, instead of retrieving the recent call list according to the number of consecutive inputs of the earphone key, the recent call list may be retrieved by long pressing the earphone key. In addition, the terminal may display a list of recently received or sent text messages in the case of a terminal in which text message reception and call origination information is displayed in the recent call list. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

As described above, the present invention has the advantage that the user can easily check the recent call list using the earphone key. In addition, there is an advantage that the user can conveniently check the phone number of the recent call list and the caller's name corresponding thereto with the voice output through the earphone.
