Provided to the control unit 301.

4 illustrates a procedure for notifying an emergency situation of using a location tracking service in a first terminal according to an embodiment of the present invention.

Referring to FIG. 4, first, in step 401, the controller 201 downloads the location tracking control application and checks whether the location tracking service is used. If the location tracking service is not used, the controller 201 proceeds to step 423. Here, the location control application program uses a wireless terminal platform such as BREW (Binary Runtime Environment for Wireless), JAVA, or Wireless Internet Platform for Interoperability (WIPI), and is downloaded through a wireless communication network when the location tracking service is subscribed.

If the location tracking service is used, the controller 201 proceeds to step 403 and checks whether control information is received from the second terminal 300. Here, the control information is a specific time zone information to track the location of the first terminal 200, the expected movement information of the first terminal 200, the location of the first terminal 200 at the specific time To include a timer period for the emergency and the emergency mode, the location information of the first terminal 200 to the second terminal 300 includes the period information to be transmitted. In addition, the estimated movement information may set an expected starting point and a destination at a specific time to track the position of the first terminal 200, and include an expected moving speed and an estimated moving path data from the starting point to the destination.

If the control information is not received, the control unit 201 proceeds to step 423 and performs a corresponding mode (eg, a standby mode). If the control information is received, the control unit 201 proceeds to step 405 and after programming the first terminal 200 according to the received control information, and confirms the position of the first terminal 200. Check the start time of the specific time zone. In step 407, the controller 201 checks the current time. In this case, the programming of the first terminal 200 sets a time to confirm the position of the first terminal 200, an expected movement path, and a movement speed according to the control information received in step 403.

After checking the current time, the control unit 201 proceeds to step 409 and compares the current time with the start time to confirm the position of the first terminal 200. If the two times (start time to check the location and the current time) do not coincide, the control unit 201 returns to step 407 to check the current time again.

If the two times coincide, the control unit 201 proceeds to step 411 to obtain movement speed information using the current position and the accelerometer using the GPS function of the first terminal 200. In operation 413, the controller 201 checks the expected movement path and the movement speed information of the first terminal 200 included in the received control information.

After that, the controller 201 proceeds to step 415 to obtain an error between the current position and the moving speed obtained in step 411 and the estimated moving path and the estimated moving speed identified in step 413 to exceed a preset limit tolerance range. Check it.

If the error between the current position and the moving speed and the expected moving path and the moving speed does not exceed the limit allowable error range, the controller 201 proceeds to step 419 to drive a timer that is extinguished at a set period. . Here, the timer is automatically expired after the time included in the control information.

After that, the controller 201 proceeds to step 421 to check whether the timer expires.

If the timer does not expire, the controller 201 ends the present algorithm. If the timer expires, the control unit 201 returns to step 411 to measure the current position and the moving speed of the first terminal 200 again. That is, when the timer expires, the control unit 201 becomes a cycle for tracking the position of the first terminal 200 set by the second terminal 300, and again the position of the first terminal 200. Will be tracked again. In addition, when the timer does not expire, since the specific time for tracking the position of the first terminal 200 passes before the timer expires, the operation of the timer is released.

On the other hand, if the error between the current position and the moving speed, the expected moving path and the moving speed exceeds the limit allowable error range, the control unit 201 proceeds to step 417 to switch to the emergency mode. Here, when the emergency mode is switched, the control unit 201 transmits the position information, the movement speed information, and the emergency mode switching signal of the first terminal 200 to the second terminal 300. Thereafter, the location information of the first terminal 200 is transmitted to the second terminal 300 until the emergency mode is released every cycle set in the control information received in step 403. In addition, in the emergency mode, when a call signal is received from the second terminal 300, the notification mode is set to silent and is automatically received. Thereafter, the controller 201 ends the present algorithm.

5 is a flowchart illustrating a procedure for recognizing an emergency situation of a first terminal and a second terminal in an emergency situation when an emergency situation occurs according to an exemplary embodiment of the present invention.                     

Referring to FIG. 5, first, the controller 301 downloads the location control application and checks whether the automatic location tracking service is used. Here, the location control application program uses a wireless terminal platform such as BREW (Binary Runtime Environment for Wireless), JAVA, or Wireless Internet Platform for Interoperability (WIPI), and is downloaded through a wireless communication network when the location tracking service is subscribed. If the location tracking service is not used, the controller 301 proceeds to step 515.

If the location tracking service is used, the controller 301 proceeds to step 503 and transmits control information to the first terminal 200 using a short message service (SMS) and data communication of a wireless communication network. Check it. Here, the control information is a specific time zone information to track the location of the first terminal 200, the expected movement information of the first terminal 200, the location of the first terminal 200 at the specific time To include a timer period for the emergency and the emergency mode, the location information of the first terminal 200 to the second terminal 300 includes the period information to be transmitted. In addition, the estimated movement information may set an expected starting point and a destination at a specific time to track the position of the first terminal 200, and include an expected moving speed and an estimated moving path data from the starting point to the destination.

When the control signal is transmitted, the controller 301 checks whether an emergency mode switch signal is received from the first terminal 200 in step 505. If the emergency mode switch signal is not received, the controller 301 proceeds to step 515 to perform a corresponding mode (eg, standby mode).

If the emergency mode switch signal is received from the first terminal 200, the controller 301 proceeds to step 507 and displays a message indicating that the first terminal 200 has been switched to the emergency mode on a display window. It generates a beep.

In operation 509, the controller 301 determines whether the user attempts to connect to the first terminal 200. If the first terminal 200 attempts to connect to the telephone, the controller 301 checks whether the user of the second terminal 300 has subscribed to the location tracking service in step 511. That is, an authentication process for confirming the user of the second terminal 300 is performed. The reason for undergoing the authentication process of the user is that, when using the emergency mode, since the second terminal 300 can control most of the functions of the first terminal 200, such as the authentication center or authentication algorithm of the wireless communication network To authenticate the user.

When the user is authenticated and connected to the first terminal 200, the controller 301 proceeds to step 513 to control the function of the first terminal 200. That is, in the case of a mobile communication terminal equipped with a microphone gain or a camera module of the first terminal 200, the surroundings of the first terminal 200 may be observed by controlling a camera function. Furthermore, all of the surrounding voice or surrounding picture data received through the first terminal 200 may be stored in a dedicated server for later use.

Thereafter, the controller 301 ends the present algorithm.
