FIG. 3 is a flowchart of a method of controlling a mobile terminal according to an embodiment of the present invention, and FIGS. 4 to 8 illustrate a method of controlling a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 3, the control unit 180 of FIG. 1 receives the emergency call request (S110) and determines whether the current position of the mobile terminal 100 (FIG.

The control unit (180 in FIG. 1) can determine whether the coverage area is out of service by using the size of the received signal periodically inputted through the wireless communication unit (110 in FIG. 1). Specifically, the control unit 180 of FIG. 1 can determine that the service area is out of order when the size of the received signal received from the base station is equal to or less than the set reference value.

If the controller (180 in FIG. 1) determines that the call is not out of call (No), it can connect the call for which the emergency call is requested (S130).

On the other hand, if the control unit 180 determines that the communication area is out of service (e.g., S140), the control unit 180 may generate a text message including at least one of location information, time information, and emergency information of the terminal.

The control unit 180 of FIG. 1 can determine at least one of the representative names corresponding to the GPS information or the GPS information received from the satellites as location information of the terminal, Information can be included in the text message.

The control unit 180 may provide a user interface to directly input or edit location information, time information, or emergency information of the terminal included in the text message. The control unit (180 of FIG. 1) may display a user interface on the display unit (151 of FIG. 1) for selecting whether to automatically repeat transmission of a text message. In addition, the control unit (180 in FIG. 1) may display a user interface on the display unit (151 in FIG. 1) capable of selecting the repetition transmission count in addition to whether the text message is automatically repeatedly transmitted.

The control unit 180 of FIG. 1 can release the size restriction of the maximum transmission signal that has been set (S150). Generally, the maximum transmission signal size of the terminal can not be set more than a threshold value according to the SAR limitation in the manufacture of a terminal, but when the above condition is satisfied, the controller (180 in FIG. 1) The size limitation of the transmission signal can be canceled.

The control unit 180 of FIG. 1 resets the size of the transmission signal to the maximum output signal of the terminal (S160), and transmits the text message to the transmission signal of the reset size (S170).

For example, when the terminal is manufactured, the maximum transmission signal size is set to 25 dBm. However, when it is determined that the communication terminal is out of order in the emergency call request, the controller (180 of FIG. 1) releases the restriction of 25 dBm, The size of the transmission signal can be reset by 30 dBm, which is the maximum output signal of the antenna. At this time, the maximum output signal size of the terminal differs according to the specifications of the terminal, and the size of the maximum output signal of the terminal is between 28dBm and 30dBm.

Accordingly, the control unit (180 in FIG. 1) can transmit the transmission signal with a signal size of 30 dBm, which is reset, so that it is possible to relatively increase the probability of transmitting a text message to the base station when it is out of the service area.

The control unit (180 of FIG. 1) displays a user interface for confirming transmission of the generated text message on the display unit (151 of FIG. 1), and may transmit a text message when receiving a transmission request of the text message from the user.

In addition, the control unit (180 in FIG. 1) may receive a response message for a text message according to a request inputted through the user interface or automatically repeat a text message until power is terminated, If it is selected, it is possible to control to repeatedly transmit the text message by the selected repetitive transmission count.

The controller (180 of FIG. 1) may display the distance between the terminal and the human body on the display unit (180 in FIG. 1) in consideration of the influence of the electromagnetic wave according to the maximum output signal of the terminal. Since the influence of electromagnetic waves is reduced as the distance between the mobile terminal and the human body decreases, the maximum output signal of the mobile terminal is limited. Therefore, when the mobile terminal is used close to the human body, Safety can be ensured by displaying the separation distance according to the increase in size on the display unit (180 in Fig. 1).

If the control unit 180 determines that the communication channel is not out of the repeating transmission of the text message, that is, determines that the terminal has entered the service area, the control unit 180 can release the repeated transmission of the text message.
