The present invention relates to a redialing method of a telephone in an exchange. More particularly, the present invention relates to a redialing method of a telephone that stores an incoming called party number and redials a selected called party number.

The redial function of a general exchange memorizes the last received number, and when the redialing button is pressed, the incoming call request is made to the stored called number so that the last dialed call is re-dialed. It is a function to perform incoming call without re-entering the number.

At this time, in the process of storing the called number, even if only one digit information is input, it is stored regardless of the number of dialed digit information. Therefore, even if the redial button is pressed, the redialing function as described above is not performed. Therefore, there is a problem in that the number to be called must be re-entered.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and an object of the present invention is to sequentially store 7 or more digits of information about a called number for performing a redial function, and to redial the selected called number. The present invention provides a method for redialing a telephone to perform the call.

According to the present invention for achieving the above object, in the redialing method of the telephone to redial the called number, if the digit information for the called number for the redial is input, the digit for the called number is input. A first step of determining whether the number of information is equal to the predetermined number of digit information; A second step of determining whether or not the digit information for the called number is pre-stored if the number of digit information for the received called number is equal to the preset number of digit information; A third step of storing digit information on the called party number if the digit information on the called party number is not stored in advance; A fourth step of displaying digit information on the called number stored in the third step when a signal for displaying the stored digit information on the called number is input; When a predetermined one of the displayed digit information is selected, a fifth step of requesting an incoming call with respect to the selected digit information is included.

Other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below by reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of an exchange for performing a redialing method of a telephone according to the present invention, in which a number key for inputting a called number for performing redialing and a called number for displaying an inputted call number The calling party subscriber telephone 10 including a key button section 11 having a display key and a redialing execution key, a display section 12 displaying a called number, and a called number input through the calling party subscriber telephone. Outputs and controls to translate the digit information for the called number input through the calling processor 20 and the calling line processor 20 which controls the called number to be displayed on the display unit 12, and the translated digit information. Control to store, read and output the stored digit information when a signal for the called number display key of the key button unit 11 is input, When a signal for selecting any one of the digit information among the jitter information is input, a translation is performed on the called number under the control of the subscriber call control unit 31 and the subscriber call control unit 31 which make an incoming request on the selected digit information. And a number translation unit 32 for outputting it to the subscriber call control unit 31, a storage unit 34 for storing and reading the digit information on the called number output from the subscriber call control unit 31, and the subscriber call control unit 31. Main line 30 consisting of a relay line call control unit 33 for controlling call processing between the call line and the called line processor 40, and the incoming call line performing the line connection to the called number requested by the main processor 30. Side line processor 40.

2 and 3 are flowcharts for performing a redialing method of the telephone according to the present invention, and FIG. 2 is a flowchart illustrating a method of inputting and storing a called number, and FIG. 3 is a called number stored by FIG. Is a flowchart on how to display and select it.

Accordingly, the operation of another embodiment of the present invention will be described in conjunction with the block diagram shown in FIG. 1 and the flowcharts shown in FIGS. 2 and 3.

First, the subscriber call control unit 31, when the incoming call is requested for the incoming number input through the calling party subscriber phone 10 in step 200 of FIG. 2, proceeds to step 201 to release the call path during the call. Otherwise, the flow proceeds to step 206 to proceed with the call between the calling party and the subscriber.

In addition, the subscriber call controller 31 proceeds to step 207 if the digit information on the called number input from the key button unit 11 is 7 or less, ignoring the digit information on the called number, and inputs an error message. If the number of digit information for the incoming called number is a predetermined number of digit information, the process proceeds to step 203 to determine whether the digit information is the same as the digit information stored in the storage unit 34.

At this time, in the present invention, the predetermined number of digit information is set to seven or more according to the station number.

As a result, the subscriber call controller 31 proceeds to step 205 and ignores the input information if the digit information for the seven or more called numbers input in step 202 and the digit information stored in the storage unit 34 are the same. If the digit information for the seven or more called numbers input in step and the digit information stored in the storage unit 34 are not the same, the flow proceeds to step 204 to control the storage unit 34 to store the input digit information.

In storing the digit information input in step 204, if the digit information for the new destination number is input while the digit information storage capacity of the destination number of the storage unit 34 is exceeded, among the digit information for the stored destination number, By clearing the digit information for the oldest called number and storing the digit information for the newly entered called number, the storage unit 34 is used efficiently.

As described above, the subscriber call control unit 31 stores the digit information of the called number in the storage unit 34, and proceeds to step 303 to turn on / off the hooking of the calling party subscriber telephone 10. Check the condition.

As a result of the check, the subscriber call control unit 31 proceeds to step 304 when the hooking off signal or the redial signal is input from the calling party subscriber telephone 10, and is the signal for the called number display key input from the calling party subscriber telephone 10? Judge.

As a result, when the signal for the called number display key is input, the subscriber call controller 31 reads the digit information about the called number stored in the storage unit 34, and as shown in the figure, the calling party line processor 20 ), And the calling party line processor 20 outputs the digit information on the called party number to the display unit 12 of the calling party subscriber telephone 10. Therefore, the display unit 12 displays digit information about the called number.

In this case, the subscriber call controller 31 proceeds to step 306, and when a signal for selecting any one of the called numbers displayed in step 305 is input, the subscriber call control unit 31 proceeds to step 307 and among the digit information for the selected called number. Redialing for any one, i.e., call occupancy is requested for the digit information for the predetermined called number selected in step 306.

Accordingly, the called party line processor 40 performs a line connection to the incoming call requested number in step 307 to proceed with the call.

As described above, in the re-dialing method of the telephone according to the present invention, if digit information about a called number for redialing a predetermined number of digit information is input, the digit information for the received called number is stored and stored. When a signal for displaying digit information for a number is input, the digit information for the stored called number is displayed, and if any one of the displayed digit information is selected, an incoming call is requested for the selected digit information to perform redialing. There is an effect of preventing waste of storage space due to unnecessary storing of the called number and storage of the same number, and unnecessary function for speed dialing.

While the invention has been shown and described with respect to certain preferred embodiments, those skilled in the art will recognize that various modifications and changes can occur without departing from the spirit and scope of the invention as set forth in the claims below.
