How to send an inter-string string message in a private exchange system

The present invention relates to a method for transmitting an inter-extension string message in a private exchange system, and more particularly, to a method for transmitting a selected string number from a string message stored in a memory to a counterpart extension.

In the conventional private switching system, when a call is requested to an extension subscriber in a call, a signal for requesting a call is applied to the extension subscriber in a call. The busy extension subscriber then ignores it or accepts the call in response to the call request. As such, in the conventional private exchange system, when a call is requested to a busy subscriber, the subscriber requesting the call can confirm if the busy subscriber terminates the current call and does not talk to the subscriber requesting the call. none. In addition, in the conventional private exchange system, even if there is an urgent call request to a busy extension subscriber, the call extension does not know the call and ignores the call request.

Accordingly, an object of the present invention is to provide a method for transmitting a string message to an extension subscriber in a call in a private exchange system.

Another object of the present invention is to provide a method of transmitting a selected string number in a string message stored in a private exchange system to a busy station.

It is another object of the present invention to provide a method for checking a string message sent to a subscriber in a call in a private exchange system.

It is still another object of the present invention to provide a method for transmitting a string message to determine the priority of a call when a subscriber in a call receives a call request in a private exchange system.

The present invention provides a display unit for outputting a message in the extension telephone of the private switching system, a memory for storing a message corresponding to the string number, and a string selection button for transmitting the string message. It is done. The private switching system including the extension telephone receives the string number after the string selection button is input, and transmits the string number to the extension subscriber in a call. In addition, the present invention is characterized in that the subscriber station receiving the string number outputs a message corresponding to the string number to the display unit.

Referring to Figure 1 will be described the overall operation of the private exchange system to which the present invention is applied. The control unit 100 performs the overall control operation of the private exchange system. The memory 101 stores a program for the control operation of the control unit 100 according to an embodiment of the present invention, and stores data generated under the control of the control unit 100. In addition, the memory 101 stores a message corresponding to a string number to be transmitted between stations according to an embodiment of the present invention. The trunk line connecting unit 102 transmits a signal transmitted from the exchanger connected through the trunk line to the switching unit 103 under the control of the control unit 100. The switching unit 103 switches the communication path under the control of the control unit 100. The DTMF receiving unit 104 is connected to the control unit 100 and the switching unit 103, converts the DTMF (Dual Tone Multi-Frequency) signal output from the switching unit 130 to digital data and outputs it to the control unit 100. When the DTMF transmitter 105 is connected to the controller 100 and the switching unit 103, the DTMF transmitter 105 outputs a DTMF signal from the controller 100 to the switching unit 103. The subscriber access unit 106 transmits the signal transmitted from the switching unit 110 to the connected telephones 111 to 11n and the signal transmitted from the connected telephones 111 to 11n to the switching unit 103 under the control of the control unit 100. The ring generating unit 107 generates a ring signal when a call request is made from a specific telephone of the trunk line connecting unit 102 or the subscriber connecting unit 106 under the control of the control unit 100, and transmits the ring signal to the telephones 111 to 11n connected through the subscriber connecting unit 106.

A method of transmitting an inter-extension string message in a private exchange system according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. In a specific embodiment of the present invention, when the subscriber 111 is in a call with the trunk subscriber or another subscriber, another subscriber 112 is to call the extension subscriber 111 in a call. When the subscriber 112 attempts to make a call to the subscriber 111 in a call, the busy tone is transmitted to the terminal of the subscriber 112. When the extension subscriber 111 hears the outgoing busy tone and confirms that the subscriber is busy, and wants to send a text message to the subscriber 111, the subscriber 112 presses a string selection button provided on the terminal to the subscriber subscriber 111 in the call. Attempt to send text.

Therefore, in step 210, the controller 100 receives a string selection button from the subscriber 112 through the subscriber access unit 106. After pressing the string selection button, the subscriber 112 enters the string number to be transmitted to the subscriber 111 in the call using the numeric keys of the telephone. Then, in step 220, the controller 100 receives a string number to be transmitted from the subscriber 112 through the subscriber access unit 106. In step 230, the controller 100 determines whether a string message corresponding to the string number input in step 220 is stored in the memory 101. When the string message corresponding to the input string number is stored in the memory 101, in step 240, the controller 100 determines whether the terminal of the subscriber 111 to which the string message is to be transmitted through the subscriber access unit 106 has a display unit. To judge. If the terminal of the extension subscriber 111 to receive the text message includes a display unit, the control unit 100 transmits the string number to the extension subscriber 111 through the subscriber access unit 106 in step 250.
