Furthermore, the communication terminal can transmit location information at a preset time even in a power-off state as well as in a power-on state. As a result, the communication terminal can easily search for the search location using the location information, and can easily share the location information.

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

In the following description, the term " power on " means that all configurations are activated in the communication terminal. That is, power is supplied to each component in the communication terminal, which means that the operation becomes possible. The term "power off" means that all configurations are deactivated in the communication terminal. In other words, the power supply is cut off in each configuration in the communication terminal, which means that the operation becomes impossible. However, when the power is off, some components of the communication terminal may be operable even when no power is supplied. The term " partially on " means that some configurations are activated at the communication terminal and others are deactivated. That is, when performing a specific function in the communication terminal, the power is supplied only to the configuration necessary to perform the specific function, it means that the operation is possible.

The term "voltage reference value" means a voltage representing a minimum voltage required for operation in a communication terminal. In other words, if the current voltage is equal to or greater than the voltage reference value, the communication terminal is operable. If the current voltage is less than the voltage reference value, the communication terminal is unable to operate. The term " voltage threshold " means a voltage set for switching a power supply state in a communication terminal. This voltage threshold is a voltage that is constant above the voltage reference. That is, when the power is on, even if the current voltage is greater than or equal to the voltage reference value, the communication terminal may power off according to the setting.

Such location information includes location data and may further include time data. In this case, the position data means coordinate data including longitude, latitude, and altitude of the corresponding position. The time data refers to time at which the communication terminal grasps position data. The term "receiving side identification information" means identification information of a destination to receive location information transmitted from a communication terminal. The receiving side identification information may be, for example, any one of identification information of a specific communication terminal, identification information of a specific web server, or identification information of a base station located within a predetermined distance from the communication terminal. The term "location information transmission time" means a time for transmitting location information in the communication terminal. The location information transmission time is composed of a specific date or day and a specific time of the date or day. The term "power management function" refers to a function for transmitting location information when the communication terminal is powered off. In order to use this power management function, the communication terminal must maintain the voltage required to transmit the location information. The term "switching function" refers to a function for transferring location information from a communication terminal and then switching or maintaining either power on or power off.

If it is determined in step 523 that the power is to be turned on, the control unit 130 returns to FIG. 2 after the power is turned on in step 525.

On the other hand, if it is determined that the power management function is not set to use the power management function in step 511, if the current voltage is less than the voltage reference value, the controller 130 detects this in step 527, and performs power off in step 529. , Return to FIG. That is, after confirming that none of the preset location information transmission functions are set to use the power management function, and then detecting that the current voltage is less than the voltage reference value, the controller 130 turns off the power.

On the other hand, if the current voltage is not detected as less than the voltage threshold in step 233, if a request for power off occurs, the control unit 130 detects this in step 243, and performs the third position information transmission function in step 245 do. At this time, the controller 130 may transmit the location information by using the reception side identification information set in advance.

In addition, the communication terminal can transmit the location information at the preset location information transmission time, not only in the power-on state but also in the power-off state. That is, since the power is turned off when the voltage measured at the communication terminal is lower than the voltage threshold higher than the voltage reference value, the location information may be transmitted using a voltage between the voltage measured at the communication terminal and the voltage reference value. As a result, the communication terminal can easily search for the search location using the location information, and can easily share the location information.
