Description

Memo function of the exchange system and dialing method using the memo function

The present invention relates to an exchange system, and more particularly, to a method for allowing a user to more conveniently perform a memo function and dial using this memo function.

Switching systems, such as private exchanges or keyphone systems, typically provide subscribers with incoming and outgoing functions. In addition, the exchange system provides various functions that allow subscribers to feel more convenient during the call or during the call. Typical functions provided to subscribers during a city call or during a call include speed dial function, one-touch dial function, hold function, transfer function, memo function, etc. There is this.

On the other hand, in the existing exchange system, the memo function simply requires the user to input the memo contents by using the keypad when trying to take a memo. At this time, the memo content can be input by the user using the keypad of the phone. Such a memo content input procedure requires a great effort. This is because there is a limit to the memo contents that can be input with 12 limited keys (1 to 9,0, *, #), and it causes a lot of inconvenience that the keypad must be operated manually when entering the memo contents. . Of course, by using a separate keypad can be more faithful input of the memo, in this case, a separate keypad must be provided.

In addition, since the existing memo function is completely irrelevant to the operation of dialing, in order to dial a phone number according to the memo content, the user must dial the confirmed phone number after checking the memo contents. In addition, when the called subscriber is absent, it is inconvenient to take a note after receiving a call by a subscriber on behalf of the absent subscriber and deliver the contents of the memo directly to the absent subscriber. In the same way, if the missed subscriber receives a call from another place, the memo is made, and the call is made again according to the contents of the memo.

Accordingly, an object of the present invention is to provide a method for allowing a user to take notes more conveniently in an exchange system.

Another object of the present invention is to provide a method for allowing a user to dial a memo directly in an exchange system.

It is another object of the present invention to provide a method of more conveniently informing the absent subscriber of the contents noted in the exchange system.

In order to achieve the above object, the present invention notes the contents of a call during an incoming or outgoing call in an exchange system that connects a telephone having a liquid crystal display (LCD) and a memory to an extension, and transmits the memo to another extension subscriber. And a method for dialing.

In a memo method during an incoming or outgoing call of an exchange system connecting a telephone having a liquid crystal display and a memory by extension according to the present invention, a first process of storing messages for a certain type of memo in a memory of the telephone; And a second process of displaying the messages stored in the memory on the LCD display in the first process when a memo input is requested from the user during a call through the telephone, and the messages displayed in the second process. A third process of displaying the input memo information together with the selected message on the liquid crystal display and storing the memo information when one of the messages is selected and the other party's memo information such as name or telephone number is inputted; Call the phone number corresponding to the stored memo information from the user, or the memo If the information received a signal set received from a user to transmit at least one other telephone station comprises a fourth process to perform its function.

DETAILED DESCRIPTION A detailed description of preferred embodiments of the present invention will now be described with reference to the accompanying drawings. 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. In addition, the terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of the user or chip designer, and the definitions should be made based on the contents throughout the present specification.

First, it should be noted that the memo function according to the present invention and the dialing operation using the memo function are handled by an exchange system configured as shown in FIG.

In FIG. 1, the controller 100 controls the overall operation of the system such as controlling call switching and providing various services to a subscriber. Read only memory (ROM) 102 and random access memory (RAM) 103 store programs and initial service data of the controller 100 for performing basic calls and various functions, and are processed by the controller 100. Temporarily save the data. That is, the ROM 102 stores program and service data, and the ROM 103 temporarily stores data generated during program execution. The timer 104 generates time data according to a value set by the controller 100 and outputs the time data to the controller 100. The switching circuit 106 switches various tones and voice data under the control of the controller 100.

The general subscriber circuit 108 supplies a call current to the general telephones A, B, C, D under the control of the control unit 100, and interfaces the signals between the general telephones A, B, C, D and the switching circuit 106. The ring generator 110 generates a ring signal and supplies the ring signal to the subscriber line. The key phone subscriber circuit 112 transmits and receives various data to and from the key phone telephones E, F, G, and H under the control of the control unit 100, and supplies a call current, between the key phone telephones E, F, G, H and the switching circuit 106. Interface the signal. Here, the key phone telephones (E, F, G, H) and the general telephones (A, B, C, D) become extension subscribers. The line connecting the general subscriber circuit 108 and the key subscriber subscriber circuit 112 to the extension subscriber becomes a subscriber line.

The tone generator 114 generates various tone signals under the control of the controller 100 and outputs them to the switching circuit 106. The trunk line circuit 116 forms a trunk line call loop under a control of the central office line under the control of the controller 100, and interfaces signals between the trunk line and the switching circuit 106. Here, the CO line means the line connecting the CO line 116 and the Central Office (C.O.).

The dual tone multi frequency (DTMF) receiver 118 analyzes the DTMF signal input from the switching circuit 106, converts the DTMF signal into digital data, and outputs the digital data to the controller 100. Here, the DTMF signal received by the DTMF receiver 118 through the switching circuit 106 may be a telephone number generated by an external subscriber through a trunk line or a telephone number generated by an extension subscriber. The DTMF transmitter (generator) 120 converts the digital data output from the control unit 100 into a DTMF signal and outputs it to the switching circuit 106.

Components described in FIG. 1 are components that can be found in a general exchange system. However, the ROM 102 stores a program according to the processing flow as shown in FIG. 2, and stores messages for a memo as shown in FIG. 3 in the RAM 103. The control unit 100 also reads the program stored in the ROM 102 and performs the processing accordingly. The subscriber's telephone is provided with a liquid crystal display (LCD) for displaying the contents of the memo, and also has a key for memo input, a key for memo dialing, and a key for memo information transmission. Each of these keys may be implemented as an actual key or may be implemented as a function key on a program. Operations according to the present invention controlled by the controller 100 may be largely classified into three types.

First, when a user requests a memo input during an incoming or outgoing call, the control unit 100 displays messages for the memo stored in RAM 103 together with a message number or message number search menu as shown in FIG. 3A. : Liquid Crystal Display. When the user selects a desired message number among the message numbers of memo messages displayed in this way or selects a message through the search menu, the controller 100 displays the selected message on the LCD. In this state, the user may input the name, phone number, etc. of the other party according to the contents of the call. Then, the control unit 100 stores the name, phone number, etc. of the other party according to the contents of the call together with the selected message in the memory 103. That is, the user can easily select a message through the message number or search menu without inputting a message for memo and input the contents of the incoming or outgoing call (call party, call party number). What you want is a note. At this time, the messages as shown in Figure 3a are messages according to the memo that users can frequently use. If the phone number is included in the memo stored in the memory, the phone number may be stored and used as a phone number for the speed dial operation.

Second, when the user selects any one of the memo messages displayed on the LCD and then inputs the name or phone number of the other party and requests the transfer of the memo information, the control unit 100 transmits the selected message and the other party's name or phone number. Send the number to the other extension telephone side. In this case, when the name or phone number of the call counterpart is transmitted as memo information as well as incoming time data, recipient information, etc., the absent subscriber will be greatly helpful in receiving the memo and grasping the information. As such, the operation of transmitting memo information may be usefully used when the called subscriber leaves his / her seat and is located at another seat nearby. More specifically, when the receiver for the number when the incoming call is not picked up from elsewhere, the data according to the content is transmitted to the original receiver's phone. In this case, the controller 100 may display the fact that the data according to the memo is transmitted on the LCD of the receiving telephone or display the LED by turning on a light emitting diode (LED).

Third, when the user inputs a phone number and makes a memo dialing request during an incoming or outgoing call, the control unit 100 dials the phone number memorized by the user so that the user can directly talk to the other party of the phone number memo. That is, in the past, the user can call the desired party only by dialing the phone number after the phone number is written on the memo during the call, but the present invention can dial the phone number immediately when there is a memo number. To make it possible. This dialing operation can be usefully used when the telephone number of the call counterpart is left as a memo.

2 is a diagram illustrating a processing flow of a memo operation, an operation for transmitting memo information, and an operation for dialing a memo phone number according to the present invention.

Now, when it is determined in step 202 that the user wants to input a memo during an incoming or outgoing call as in step 201 of FIG. 2, the control unit 100 stores a message for a memo of a certain type as shown in FIG. 3A stored in a memory. Is displayed on the LCD of the phone. When the user selects a message number or selects a desired message menu in this state, the control unit 100 determines the selection in step 203, and performs the next operation according to the menu in step 204. Here, the next operation according to the menu means that the control unit 100 displays on the LCD of the phone so that the user can input the phone number or name of the other party during an incoming or outgoing call. An example of memo information input by the user by the processing of the control unit 100-the name of the other party ("Hong Gil-dong") and the telephone number ("TEL: 123-4567") is shown in FIG. 3B. Memo information input from the user is displayed on the LCD and stored in the memory.

In operation 204, the user may request that memo information be transmitted to another extension telephone while the next operation according to the menu is performed, or the input telephone number may be directly dialed. When the user requests the transmission of the memo information, the control unit 100 determines the request in step 205, and in step 208, the internal time (incoming time) and the receiver information of the system are also transmitted along with the memo information. If the user requests that the entered telephone number is directly dialed, the control unit 100 determines this request in step 206, and dials the entered telephone number using the DTMF transmitter 120 of FIG. Control so that the user can talk to the other party. The operations of steps 206 and 207 may be performed even after the memo information is transmitted.

On the other hand, if the user or the other party of the user hooks on the phone and requests completion of the call while the phone number is dialed and the memo is dialed, the control unit 100 controls the switching circuit 106 according to the request. Blocks the established channel and terminates the call.

As described above, the present invention stores a certain type of messages frequently used by users as a message for memo in memory and allows the message to be displayed on the LCD of the phone when the user requires memo input. . From this display, the user can simply take a note by inputting only the name or phone number of the counterpart without inputting a message for the memo. In addition, the present invention can transmit the contents of the memo without writing directly to the memo after writing the content of the memo, there is an advantage that it is possible to simply dial the memo phone number by one key operation.

Meanwhile, in the detailed 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, in a specific embodiment of the present invention has been described the case that the message for the memo is a message of the type as shown in Figure 3a, the text, number and type of such a message may be changed by the user. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.
