The present invention relates to a dial method of a key telephone system, and more particularly, to a method for performing a speed dial according to a destination name.

1 is a block diagram of a key telephone system, which includes a CPU 10 for controlling call switching and processing to provide various services, a program for performing basic calls, and various functions. ROM 11 which stores service data, RAM 12 which temporarily stores data generated during program execution with program and data processing memory, and key phone subscriber circuit for interfacing data and voice signals between the key phone and the system. 13, a switching circuit 14 for switching various tones and speech data under the control of the CPU 10, and various tone signals under the control of the CPU 10 to generate the switching circuit ( 14) a digital type of a tone supply unit 15 for outputting to the user, a ring generator 16 for generating a ring sipnal of a square wave to the subscriber line, and an MFC signal for the subscriber outputting the keyphone subscriber circuit 13; A DTMF receiver 17 for transforming into a digit digital signal and outputting it to the CPU 10, a DTMF transmitter 18 for converting and outputting a digital digit signal into a DTMF signal under the control of the CPU 10, and Under the control of the CPU 10, a CO line circuit 19 which forms a trunk line loop by intersecting a CO line line and interfaces a signal incoming to the CO line, and a tone signal of a CO line switch through the CO line And a tone detector 20 for detecting, and an input / output device 21 for interfacing between a terminal such as a printer or a computer and a system.

The process of performing a conventional speed dial in a key telephone system as described above will be described. To perform speed dialing, the user hooks off the keyphone telephone and presses the speed dial key and a unique speed dial ID corresponding to the number specified in the system. Then, the CPU 10 recognizes the hook-off state through the key-phone subscriber circuit 13 in step 211 and controls the switching circuit 14 and the tone supplier 15 to supply a dial tone to the key-phone subscriber. After that, in step 212 and 213, a key signal generated through the key phone is received through the DTMF receiver 17. At this time, the received key signal is a speed dial key and an ID signal. Therefore, the CPU 10 reads the telephone number corresponding to the speed dial ID from the RAM 12 in step 214 and converts the read telephone number into a DTMF signal through the DTMF transmitter 18 to perform a dialing function. do.

However, in the conventional method as described above, in order to make a designated speed dialing, a large amount of speed dial ID must be known, which causes a problem of speed dialing being complicated.

Accordingly, an object of the present invention is to provide a method of registering a destination name to perform a speed dialing function in a key telephone system, and then searching and dialing a desired number by the destination name.

Hereinafter, the present invention will be described in detail with reference to the drawings. The configuration of the key telephone system for carrying out the present invention is the same as in FIG. 1, and the reference numerals are the same in FIG.

3 is a block diagram of a dial portion of a key panel component layer of a key-phone telephone, which performs a function for naming a destination using a ten key.

4 illustrates a process of receiving a speed dial number along with a corresponding destination name in order to perform speed dialing according to the present invention.

5 is a flow chart for performing a speed dialing function according to the present invention. The system registers a user based on a directory concept, searches and scrolls speed dials based on a destination name, selects a desired destination, and then selects a speed dial. Dial the destination by key.

The present invention will be described in detail based on the above configuration.

First, a process of registering a speed dial number with a corresponding destination name in order to perform a speed dial function as a destination name will be described. When the key phone subscriber hooks off, the CPU 10 recognizes this through the key phone subscriber circuit 13 and prepares for key input as described above. At this time, if the key-phone subscriber generates the speed dial key and the speed dial ID continuously, the CPU 10 recognizes that the speed dial function is received through the DTMF receiver 17 and recognizes the speed dial function. Know the dial ID. Thereafter, the key-phone subscriber generates a destination name corresponding to the corresponding phone number. To generate an initial character of the destination name, the keypad subscriber uses a numeric key panel as shown in FIG. For example, if the first character of the destination name is C, press the 2 key three times; for K, press the 5 key twice. Therefore, when the speed dial key and ID signal are received as described above, the CPU 10 prepares to receive the next input key signal as a destination name. Therefore, when a text signal is generated using the numeric keys as described above, the CPU 10 receives the corresponding key signal as the destination name in step 403, and manages the destination name in the received phone number in step 404. Register in the table.

Therefore, when performing the flow as shown in FIG. 4, the telephone number for speed dialing is sequentially registered in the corresponding destination name management table according to the destination name.

When the creation of the speed dial table according to the destination name is completed as described above, the speed dial function is performed in the flow shown in FIG. First, instead of generating a speed dial ID, the key-phone subscriber performs a speed dial function with a destination name. To this end, the key phone subscriber first presses a directory key, and the CPU 10 receives the directory key in step 501. In addition, the key phone subscriber generates a first letter key signal of a desired destination name using a numeric key panel as shown in FIG. 3 after generating a directory key. Then, the CPU 10 recognizes the key signal received in step 502 as a text signal. In step 503, the CPU 10 determines the text signal as the first letter of the destination name for the speed dial. The first destination in the table is found and displayed on the LCD of the keyphone subscriber.

At this time, the user checks the contents displayed on the LCD of the keypad phone and checks whether it is the desired destination. If the desired destination is pressed, the speed dial key is pressed. However, if it is determined in step 504 that the next key is determined, the CPU 10 receives the next key signal in step 505, displays the next content registered in the destination management table in step 506 as a destination, and then enters the destination in step 504. Return to step). Therefore, if the content currently displayed on the LCD of the keypad phone is not the desired destination, the desired key is searched by scrolling through the contents of the object management table by repeatedly using steps 504 to 505. . When the desired destination is found, the keypad player presses the speed dial key. Then, the CPU 10 recognizes this in step 504 and outputs the telephone number currently displayed in step 507 through the DTMF transmitter 18 to perform an automatic dialing service function.

Therefore, when performing the speed dial function according to the present invention, first determine the destination name using the directory key and the first letter key of the destination name, then select the desired destination while scrolling the destination management table using the next key and then speed dial The key serves the dialing function.

As described above, in a key telephone system that performs a large amount of speed dialing functions, a desired dial number is sequentially registered in the destination name table according to the destination name, and when the speed dialing function is performed, a dialing function is performed to find a desired destination. By doing so, there is an advantage that speed dialing can be easily performed.
