Description

How to display the operation status of a key-phone phone {METHOD FOR DISPLAYING OPERATION STATE OF KEYPHONE SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key phone telephone, and more particularly, to a method for displaying various operation states of a key phone telephone by using LEDs in the key phone telephone.

Typically, the phone phone is equipped with LEDs for displaying the operation status for each function button to indicate the state of the function. That is, for example, in the case of the message button, the corresponding LED of the message button is turned on when there is a message, and in the case of the speaker button, the LED of the speaker button is turned on when the speaker phone mode is in use. In case of CO line button, when the designated CO line is received, the LED will be flickering and when the call is connected, the LED will be on.

As described above, the LED of the conventional phone phone is used only for the purpose of the corresponding button, and thus there is a problem that various operation states of the phone phone cannot be represented in detail.

Accordingly, an object of the present invention is to provide a method for displaying various operating states of a key phone by using an LED.

According to an aspect of the present invention, there is provided a method of displaying an operating state of a keyphone telephone, the method comprising: receiving and storing LED control data according to the keyphone telephone operating state, and the LED control data is ring LED on data. And controlling the display to distinguish the rings according to the type of the ring received by the keypad phone, and to control the LED control data to "call". In the case of data, a process of controlling one of the two LEDs to be turned on and displaying the same, and if the LED control data is a "message receiving" LED on data, flashing one LED of the two LEDs at a predetermined cycle. Characterized in that it comprises a process of controlling to display.

2 is a process flowchart for displaying the operation state of the key-phone telephone according to the embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description and in the accompanying drawings, in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a block diagram of a key-phone telephone to which an embodiment of the present invention is applied. Referring to FIG. 1, the control unit 102 controls the overall operation of the key phone, and generates and applies LED control data to the LED control unit 104 according to various operation states of the key phone in accordance with an embodiment of the present invention. Let's do it. The memory unit 108 stores a control program for controlling the operation of the key phone, and temporarily stores data generated when the control program is executed. The call path connection unit 100 may be implemented as a relay, and performs a switching operation under the control of the controller 102 to connect the call paths between subscribers. The key input unit 106 includes a plurality of function keys and numeric keys for performing a dial function. In addition, the key input unit 106 includes two LEDs that are displayed in different colors (for example, red and green) to indicate various operation states of the key phone according to the embodiment of the present invention. The key input unit 106 generates corresponding key data when the user presses a predetermined key and outputs the corresponding key data to the control unit 102. At this time, in the exemplary embodiment of the present invention, the display color of the LED included in the key input unit 106 is composed of red and green, but the display color of the LED may be changed to another color.

The LCD controller 110 receives key data generated by the key input unit 106 and various information signals of the controller 102 under the control of the controller 102 so that the key data information and various information are displayed on the LCD. The LED control unit 104 controls the on / off of various LEDs provided in the key input unit 106 under the control of the control unit 102, and also operates the key phone according to the embodiment of the present invention from the control unit 102. The on / off of the LED indicating the status is controlled by receiving the LED control data.

2 is a flowchart illustrating an on / off operation control flow of an operation state LED for displaying various operation states in a key phone according to an exemplary embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when a ring is received from the outside of the key phone, the key phone is busy by the user, or a message is received by the key phone, the key phone telephone control unit 102 recognizes the operation and corresponds to the state of the key phone. Generates control data of the status LED and applies it to the LED controller 104. Accordingly, the LED controller 104 receives and stores the LED control data applied from the controller 102 in step 200 of FIG. 2, and then analyzes the LED control data. At this time, if the LED control data is "ring" LED on data, the LED control unit 104 proceeds from step 202 to step 204 to receive the ring from the CO line, and the two key input units 106 are provided. One LED of one of the two different operating state LEDs of different colors is controlled to blink, and when receiving a ring from the station, the LED of a different color from the CO line ring reception is controlled to blink. Accordingly, the user can recognize the ring received by the key-phone telephone according to the blinking state of the LED, and can also distinguish the type of the ring. That is, for example, the green LED blinks when receiving a ring from a trunk line and the red LED blinks when receiving a ring from an extension so that a user can easily distinguish the type of ring.

In contrast, when the LED control data received from the control unit 102 in the step (200) is the "on-call" LED on data, the LED control unit 104 proceeds to step (208) in response to this in step (206). By turning on one of the two different operating state LEDs of the different color provided in the key input unit 106 to indicate that the phone phone is currently in a call. Accordingly, the user can see whether the phone is busy by viewing the on state of the LED.

On the contrary, if the LED control data received from the controller 102 in the step (200) is the "message received" on data, the LED controller 104 proceeds to step (212) in response to the step (210) and the A specific LED of one of two different operating state LEDs of a key input unit blinks at a predetermined period to control the reception of the message. At this time, the blinking period of the LED indicating the message reception is set to be longer than the LED blinking period at the time of ring reception in step 204 to control to distinguish between the message reception and ring reception. Accordingly, the user can easily know whether the message is received from the key phone.

As described above, the present invention uses two LEDs in the key phone to display various operating states of the key phone, so that the user can easily know the operating state of the key phone.
