Description

Dialing by Name in a Private Switching System

The present invention relates to a method of dialing in a private switching system, and more particularly, to a dialing method using a called party's name.

In general, the private exchange system performs a switching operation and a call processing operation for forming a call path between extension subscribers or a call path between a subscriber and a trunk subscriber according to a request of a subscriber.

In the private exchange system, the dialing method of the extension subscriber is the most common method of dialing a numeric key corresponding to the telephone number to which the subscriber directly calls. In this case, the subscriber must know the telephone number to which he / she wants to call. Therefore, there is a problem that the extension subscriber can not make a phone call if they do not know the telephone number they want to call.

Thus, in order to prepare for the case that the extension subscribers do not know the telephone number they want to call, the conventional private exchange system provides a system speed dialing function. In the conventional system speed dialing function, an operator of a system registers and registers up to 10,000 numbers. Then, the extension subscriber of the private switching system providing the conventional system speed dialing function dials by selecting a system speed dial function and pressing a serial number corresponding to the telephone number to be dialed. However, such a conventional system speed dialing function also has a problem that the extension subscriber should remember the serial number corresponding to the telephone number he / she wants to dial.

Accordingly, an object of the present invention is to provide a method for dialing by entering a name of a called party in a private exchange system.

Another object of the present invention is to provide a method of searching and dialing a registered telephone number without directly inputting a telephone number of a called party in a private exchange system.

It is another object of the present invention to provide a method for speed dialing a system by the name of a called party in a private switching system.

In order to achieve the above object, the present invention provides a name corresponding to a character input from an extension subscriber in a system speed dialing mode in a private exchange system having at least a memory for storing a telephone number and a name in correspondence with the display unit of the subscriber station. If the name is output from the extension subscriber to the display unit is selected after the output is characterized in that for dialing the corresponding telephone number.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a schematic block diagram of a private switching system to which the present invention is applied and includes a control unit 110, a memory 111, a switching unit 112, a trunk line connecting unit 113, a subscriber connecting unit 114, and a DTMF receiving unit ( 115), DTMF transmitter 116, ring generator 117, tone generator 118, and subscriber terminals 121-12n.

Referring to Figure 1 describes the overall operation of the private exchange system to which the present invention is applied. The controller 110 controls the overall operation of the private exchange system according to the present invention. The memory 111 stores a control program and data as shown in FIG. 2 to control the operation of the private exchange system according to the present invention. The memory 111 also stores a telephone number database in which the called party's name and telephone number are associated with each other as shown in FIG. The switching unit 112 switches various tones and voice data under the control of the control unit 110. The trunk line connecting unit 113 scissors the trunk line to form a trunk line call loop, and interfaces the signals transmitted and received between the switching unit 112 and the trunk line under the control of the controller 110. The subscriber access unit 114 interfaces the signals transmitted and received between the subscriber station 121 to 12n and the switching unit 112 under the control of the control unit 110. The DTMF receiver 115 analyzes a DTMF signal input from the switching unit 112, converts the DTMF signal into digital data, and outputs the digital data to the controller 110. Here, the DTMF signal input to the switching unit 112 is a telephone number generated by the trunk line subscriber or a telephone number generated by the extension subscriber. The DTMF transmitter 116 converts the digital data output from the controller 110 into a DTMF signal and outputs it to the switching unit 112. Here, the DTMF signal output from the DTMF transmitter 116 becomes the telephone number of the trunk line subscriber generated when the station side calls the trunk line side. The ring generator 117 generates a ring signal and supplies the ring signal to the subscriber line. The tone generator 118 generates various tone signals under the control of the controller 110 and outputs them to the switching unit 112. Subscriber terminals 121 to 12n are terminals of extension subscribers, and as shown in Fig. 4, are provided with at least keys and a display unit which correspond to letters in numbers. At this time, one of the characters corresponding to the number is selected according to the number of times the numeric key is input under the character input mode. For example, in the character input mode, when the numeric key 1 is pressed once, the letter A is input. When the numeric key 1 is pressed twice in succession, the letter B is input. When the numeric key 1 is pressed three times in succession, the letter C is input.

2 is a control flowchart according to the present invention, when a name starting with an input character in the character input mode according to the system speed dialing function is output after being displayed on the display unit of the subscriber station, dialing a telephone number corresponding to the selected name. do.

A method of dialing a telephone number by inputting a name of a called party in a private switching system according to an embodiment of the present invention will be described with reference to FIGS. First, the extension subscriber presses a function key or a function code for selecting a system speed dialing function through the subscriber terminal for dialing according to the present invention. Then, in step 210, the controller 110 determines whether the system speed dialing function is selected from the predetermined subscriber station through the subscriber access unit 114. When the system speed dialing function is selected, in step 220, the controller 110 controls the subscriber access unit 114 to display a menu according to the system speed dialing function on the display unit of the subscriber terminal which selects the system speed dialing function. do. In this case, the menu according to the system speed dialing function is a menu for selecting a character input mode or a numeric input mode according to the present invention. Accordingly, the extension subscriber who selects the system speed dialing function selects a text input mode or a numeric input mode from a menu output to the display unit. In operation 230, the controller 110 determines whether the text input mode is selected from the subscriber terminal that has selected the system speed dialing function through the subscriber access unit 114. If the letter input mode is not selected, the controller 110 determines that the number input mode is selected, and dials a phone number corresponding to the serial number input from the subscriber terminal through the subscriber access unit 114 in step 235. do.

In contrast, when it is determined that the text input mode is selected, the controller 110 inputs a name for inputting the name of the other party to be called to the display unit of the subscriber station which selected the text input mode through the subscriber access unit 114 in step 240. Print a request message (for example, input name :). Then, the extension subscriber who confirms the output name input request message inputs the first letter of the name of the counterpart. In step 250, the controller 110 receives a character corresponding to the first letter of the name of the counterpart that the extension subscriber wants to call through the subscriber access unit 114. Then, in step 260, the controller 110 retrieves a name starting with the input character from the telephone number database stored in the memory 111 and outputs the name to the display unit of the subscriber terminal through the subscriber access unit 114. In this case, if there are a plurality of names starting with the input characters in the telephone number database, the names having the highest priority are output first.

Then, after confirming the name output to the display unit, the extension subscriber presses a function key or a function code to select and display the displayed name if the name of the other party to whom he / she wants to call is correct. On the contrary, the extension subscriber checks the name output to the display unit and then presses a key for retrieving a stored name before and after the displayed name from the stored telephone number database if the name of the other party is not the name of the counterpart.

In operation 270, the controller 110 determines whether the name currently displayed on the display unit is selected from the subscriber station through the subscriber access unit 114. If it is determined that the name displayed on the display unit is not selected, in step 275, the control unit 110 displays the number 260 in the telephone number database according to a search key input from the subscriber terminal through the subscriber access unit 114. Retrieve the name stored before and after the name displayed in step.

In contrast, if it is determined that the name currently displayed on the display unit is selected, the control unit 110 dials a phone number corresponding to the name output to the display unit in step 280.

As a specific embodiment of the present invention, a case where the name of the counterpart to whom the extension subscriber wants to call is KIM HAN IL will be described with reference to FIGS. 1 to 5. First, the extension subscriber presses the system speed dial function key through the extension terminal and checks a menu according to the system speed dial function output to the display unit. The subscriber then selects a text input mode according to the system speed dial function. Then, the extension subscriber enters the first letter of the name of the other party he wants to call. At this time, since the name of the counterpart that he / she wants to call is KIM HAN IL, he presses the numeric key 4 consecutively twice under the letter input mode in order to enter K, the first letter of the counterpart's name. Then, the control unit 110 outputs the name starting with the name K from the database stored in the memory 111 to the display unit of the subscriber station. In this case, as shown in FIG. 3, if there are several names starting with K among the names stored in the database, the KIM HAN IL which is the highest priority name is output. When the name stored in the database is output to the display unit, a phone number corresponding to the name may also be output as shown in FIG. 5. Then, the extension subscriber checks the KIM HAN IL outputted to the display unit of the extension terminal and selects it as the name of the other party to which he / she wants to talk. The controller 110 corresponds to the KIM HAN IL in the database stored in the memory 111. Dial 123-4568.

As described above, the present invention can register a name and a phone number of the other party to be called in a private exchange system in advance, and can easily dial without receiving a phone number directly from the subscriber.
