Abstract

The present invention relates to an emergency call transmission and reception display method of a mobile communication terminal, and conventionally, even if a call is received, the user cannot distinguish whether it is an emergency call or a normal call. There was a problem that can be turned off inadvertently. In view of the above problems, the present invention comprises the steps of: receiving an input of a telephone number to make a call from a transmitting terminal, selecting whether to transmit the call as an emergency call or a normal call, and setting the data / control packet to call the other party; The receiving terminal determines the bits set in the data / control packet received from the transmitting terminal, and changes the color of the LED indicating whether it is an emergency call or a normal call and emits light. There is an effect that can make a call by distinguishing the call by checking the color of the LED lighted up according to the call type.

The present invention relates to a method for transmitting and receiving an emergency call of a mobile communication terminal, and more particularly, a mobile communication in which the emergency level of a call can be distinguished and transmitted so that the receiving side can distinguish the emergency level of the call so as to change the emission color of the LED. An emergency call transmission and reception indication method of a terminal.

In general, a mobile communication terminal vibrates or rings according to a vibration mode or a bell mode set when a call is received to notify a user of a call reception state. For example, when the mobile communication terminal is set to the vibration mode, the LED installed on the outside flickers, and when a short message is received, the LED installed on the outside flickers and a beep sound is generated to notify the user of the incoming state.

However, in the prior art as described above, the mobile communication terminal is notified by the flashing and vibration of the LED that the call was received when there is a call in the vibration mode, the user can not distinguish between the emergency degree of the call and must first talk to the other party There is a problem.

In addition, in the conventional mobile communication terminal, even if a call is made, the user may not distinguish whether it is an emergency call or a normal call, so it may not be thought that it may be annoying call or may inadvertently turn off the terminal. Therefore, there is a problem that there is no means for notifying the user when an actual emergency call is received.

Accordingly, the present invention has been made in view of the above problems, and the user can see the call by changing the emission color of the LED by distinguishing the emergency degree of the call from the transmitting side and distinguishing the emergency degree of the call from the receiving side. An object of the present invention is to provide an emergency call transmission and reception indication method of a mobile communication terminal capable of determining reception.

In order to achieve the above object, the present invention provides a method of calling a counterpart by receiving a telephone number of a party to make a call from a transmitting terminal, selecting whether to transmit the call in an emergency call or a normal call, and setting it in a data / control packet. Steps; And determining, by the receiving terminal, the bit set in the data / control packet received from the transmitting terminal to change the color of the LED indicating whether the call is an emergency call or a normal call to emit light.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating an emergency call transmission and reception display method of a mobile communication terminal according to an embodiment of the present invention. As shown in FIG. Selecting whether to transmit and setting it in a data / control packet and calling a counterpart when the call key is pressed (S11 to S14); Ringing a bell indicating that there is a call received from the receiving terminal, and determining the bit set in the data / control packet received from the transmitting terminal to change the color of the LED indicating whether it is an emergency call or a normal call to emit light ( S21, S22); When the receiver checks the color of the LED and presses the call key, the call is connected to the transmitting terminal and the receiving terminal, and the process ends when the call is completed (S23 to S25).

Suppose a user makes an emergency call to a counterpart using a mobile communication terminal.                     

The user inputs the phone number of the counterpart terminal and selects whether the current call is an emergency call or a normal call (S11 to S13).

Setting an emergency call or a normal call configures the user interface to be selected from a menu provided by the mobile communication terminal so that the user can select it. The selected call type is allocated to the data / control packet by 1 bit and is set to '1' or '0' to be transmitted to the counterpart terminal.

When the user presses the call key, a ringer notifies the other terminal of the call reception (S14, S21). The counterpart terminal receives the data / control packet, recognizes it as a control factor of the LED, and outputs a control signal for changing the color of light emitted from the LED.

The counterpart terminal determines whether the LED control factor allocated to the data / control packet is '1' or '0'. The counterpart terminal outputs a '1' or '0' signal to the base of the transistor Tr of the LED display unit illustrated in FIG. 2 in response to the set bit.

For example, when the signal '0' is input to the base, the transistor Tr is turned off, and conversely, when the signal '1' is input, the transistor Tr is turned on. That is, when the signal is '0', the emergency call is not selected, and the green LED 10 emits light when the counterpart terminal recognizes the normal call. At this time, the green LED 10 is a low active LED is used.

On the contrary, when the signal '1' is input to the base, the other terminal recognizes the emergency call and the blue LED 20 emits light. At this time, the blue LED 20 is a high active LED is used.                     

3 is an explanatory diagram showing an example in which the LED of the mobile communication terminal emits light in different colors according to the type of the received call. As shown in the drawing, the LED 10 is displayed in green when the call is a normal call. When the call is an emergency call, the LED 20 will be described in blue.

Therefore, the color of the LED is selected as blue or green according to the on / off state of the transistor corresponding to the emergency call or the normal call.

The other party checks the color of the light emitting LED to determine whether the received call is an emergency call or a normal call, and determines whether to call the user (S23). When the other party presses the call key, the call is connected between the user and the other party and ends when the call ends (S24, S25).

As described in detail above, the present invention has the effect that the user can make a distinction between the emergency call and the normal call to check the color of the LED emitting light according to the call type, the call can be divided to receive the call.
