In addition, the electronic device may be connected to another electronic device through the short range communication module 114 or the interface unit 160 included in the wireless communication unit 110.

The controller 180 also performs a function of relaying a signal between an external electronic device and the wireless Internet. That is, it supports the external electronic device to access the wireless Internet, and relays signals transmitted and received between the external electronic device and the wireless internet. For example, the controller 180 performs a function of a modem, a hot spot, a wireless access point, etc., for relaying a signal between an external electronic device and the wireless internet.

In this document, a function of relaying a signal between an external electronic device and the wireless Internet is called a tethering function, and a mode in which the tethering function is activated is called a tethering mode.

The controller 180 may also be included in the wireless internet module 113 to reduce and output power of a transmission signal transmitted through the wireless internet module 113 by a specific value when entering the tethering mode. Control the power amplifier.

In this document, an operation of reducing the power of a signal transmitted through the wireless internet module 113 by a specific value and outputting the same is called power back off.

2 is a flowchart illustrating a power control method of a mobile terminal according to a first embodiment of the present invention. 3 is a view for explaining a power control method of a mobile terminal according to a first embodiment of the present invention.

Referring to FIG. 2, when the controller 180 enters a tethering mode for relaying a signal between an external electronic device and the wireless Internet (S101), the controller 180 returns the power of a signal transmitted through the wireless Internet module 113 to a back off value. The power back off function is reduced and output as much as S102. That is, the power amplifier included in the wireless internet module 113 is controlled to reduce and output power of a signal transmitted through the wireless internet module 113 by a specific value.

In addition, when the tethering mode ends (S103), the controller 180 releases the power backoff of the transmitted signal (S104). That is, the power amplifier included in the wireless internet module 113 is controlled to transmit a signal at normal transmission power.

In the above-described steps S101 and S103, entry and exit of the tethering mode may be selected by the user. Accordingly, the controller 180 may determine entry into and exit from the tethering mode, based on a user's control input.

In addition, in step S102, when the power back off, the back off value indicating how low the transmission power can be selected by the user.

3 illustrates an example of a screen for controlling a back off value.

Referring to FIG. 3, the controller 180 displays a setting window W3 for setting a back off value through the display module 151 when the transmission power is back off. Accordingly, the user can set the back off value 3c up to 0 dB to the maximum possible transmit power using the buttons 3a and 3b displayed in the setting window W3.

In addition, when the setting window W3 is displayed on the screen, the controller 180 additionally displays a message informing that a communication failure may occur because the power of the transmission signal is too low when the backoff value is set to a specific value or more. can do.

In addition, in step S102, when the power back off, the back off value indicating how to lower the transmission power may be adaptively changed according to the transmission power allowed by the base station. For example, as the transmission power allowed by the base station to the mobile terminal is higher, a decrease in transmission power may increase during power back-off.

In general, when the mobile terminal enters the tethering mode, the electromagnetic wave absorption ratio is increased than before entering the tethering mode. Therefore, in the first embodiment of the present invention, while the mobile terminal is operating in the tethering mode, by reducing the power of the transmitted signal by a predetermined value, there is an effect of reducing the electromagnetic wave absorption ratio.

4 is a flowchart illustrating a power control method of a mobile terminal according to a second embodiment of the present invention. 5 is a view for explaining a power control method of a mobile terminal according to a second embodiment of the present invention.

Referring to FIG. 4, the controller 180 displays a plurality of modes related to power back-off of a signal transmitted through the wireless internet module 113 through the display module 151 (S201). Each mode has a corresponding power back off value.

If any one of a plurality of modes related to the power back off is selected (S202), the controller 180 controls power back off of the transmission signal based on the selected mode (S203).

For example, when the selected mode corresponds to power back off deactivation, the controller 180 controls the power amplifier included in the wireless internet module 113 to output a transmission signal without power back off.

Also, for example, when the selected mode corresponds to power back off activation, the controller 180 may reduce the power of the transmission signal by the power back off value corresponding to the selected mode and output the reduced power of the wireless Internet module 113. Control the power amplifier.

When there are a plurality of modes corresponding to the power back off activation, the power back off value corresponding to each mode is set differently.

Referring to FIG. 5, the controller 180 displays a plurality of selectable modes 5a, 5b, and 5c on the screen in relation to power back-off of a transmission signal. In addition, when any one of the plurality of modes 5a, 5b, and 5c is selected, power back-off of the transmission signal is controlled based on the selected mode.

For example, when the 'OFF' mode is selected, the controller 180 deactivates the power back off of the signal transmitted through the wireless internet module 113.

For example, when the 'normal mode' 5b or the 'infant mode' 5c is selected, the controller 180 activates the power back-off of the signal transmitted through the wireless Internet module 113, and selects the selected mode. The power of the transmission signal is reduced and output using the back off value corresponding to the mode. In the case of the 'infant mode' 5c, the corresponding backoff value may be set larger than that of the 'normal mode' 5b in order to reduce electromagnetic waves harmful to a human body.

Meanwhile, in the above-described second embodiment of the present invention, the case where the transmission signal to which the back off is applied is a signal transmitted through the wireless internet module 113 has been described as an example, but the present invention is not limited thereto.
