2 is a flowchart illustrating an embodiment of a method for registering location information of a portable device and a method for providing location information of the portable device using the same.

First, while performing communication functions between the mobile communication terminal A 10 and the portable device 20 (200), the received electric field strength of the mobile communication terminal A 10 and the portable device 20 with each other is increased. It periodically checks whether it is lowered below the threshold (201).

As a result of the inspection, when the reception electric field strength of the mobile device 20 with the mobile communication terminal A 10 falls below a threshold, the mobile device 20 searches for a mobile communication terminal located nearby ( 202).

In this case, several mobile communication terminals may exist in the vicinity of the portable device 20. In order to provide more accurate location information of the portable device, the portable device 20 performs a near field communication function with a nearby mobile communication terminal to receive a reception electric field. It is desirable to search for the mobile terminal having the greatest intensity.

Here, the portable device 20 may warn the child of the fact that the mobile communication terminal A departure (falling more than a certain distance from the parent) when the received electric field strength with the mobile communication terminal A (10) is lower than the threshold.

In addition, the portable device 20 may set the loss mode to prevent others from using the portable device 20 when the received electric field strength with the mobile communication terminal A 10 is lower than the threshold. That is, the information upload function of the portable device 20 is not performed when a child lacking the perceptual ability is turned off by erroneously manipulating a button or the like of the portable device 20 in a state far from the parent, and thus the portable device ( It is preferable that the loss mode is set in 20).

On the other hand, even if a user possesses the mobile communication terminal A 10 and the portable device 20 and then loses the portable device 20, the portable device 20 can be used to prevent others from picking up and using the lost portable device 20. It is preferable that the loss mode is set in the device 20.

On the other hand, in the test result 201, the mobile communication terminal A (10) alerts the parents of the departure of the portable device (child is more than a certain distance from the parent) when the received electric field strength with the portable device 20 is lower than the threshold value It is desirable to.

As a result of the mobile communication terminal search 202, when the mobile communication terminal B 30 located nearby in the portable device 20 is searched (203), the portable device information (e.g., PIN) in the portable device 20 is searched.

As another example, the mobile communication terminal B 30 does not check the current location information, but the mobile communication terminal B 30 based on the base station information that was connected when the mobile terminal B 30 at the time when the mobile terminal B 30 transmits the portable device information. The location information of the terminal B 30 may also be checked.

Here, since the portable device 20 does not directly transmit information to the terminal location information providing server 50 but is not equipped with the positioning function, the mobile device 20 transmits its own location information to the terminal location information through the mobile communication terminal B 30. This is to inform the providing server 50. That is, since the mobile communication terminal B 30 is a terminal located close to the child, the location of the lost child and the mobile communication terminal B 30 are the same.

Then, when the terminal location information providing server 50 receives the information (eg, PIN) of the portable device 20 and the location information of the mobile communication terminal B 30 from the mobile communication terminal B 30, the mobile device ( The mobile communication terminal corresponding to the portable device 20 is searched through the terminal registration DB 60 using the information (for example, PIN) of 20) as a parameter (206).

As a result of the mobile communication terminal search (206), when the mobile communication terminal A 10 corresponding to the portable device 20 is searched by the terminal location information providing server 50 (207), the terminal location information providing server 50 In step 208, a callback message is generated using the location information of the mobile device 20 and the information (for example, a phone number, etc.) of the mobile device 20 determined based on the location information of the mobile communication terminal B 30 (step 208). In operation 209, the SMS center 70 requests the SMS center 70 to transmit the callback message to the mobile communication terminal A 10.

Then, the SMS center 70 transmits a callback message including the location information of the mobile device 20 and the information (eg, a phone number) of the mobile communication terminal B 30 to the mobile communication terminal A 10. (210).

Then, the mobile terminal A 10 receives the callback message and displays a callback message including the location information of the mobile device 20 and the information (eg, a phone number) of the mobile terminal B 30 on the screen. (211).

3 is a diagram illustrating an embodiment of a lost location callback message to which the present invention is applied.

As shown in FIG. 3, the screen of the mobile communication terminal A 10 includes location information of the portable device 20 (eg, “near Sangdong, Wonmi-gu, Gyeonggi-do”, etc.) and information of the mobile communication terminal B 30 (eg; "011-234-5678", etc.) are displayed in the form of a callback message.

Here, parents can recognize that Mia is located near "Sang-dong, Wonmi-gu, Gyeonggi-do," and then select "Map View Button" to go to the Map Web (Wap) page to find out the detailed location.

In addition, the parent may recognize that the third party is located near the area where the lost child is located, and then select the "connect call button" to call the third party and ask for the detailed location of the lost child.
