Abstract

An apparatus for locating a mobile device includes a receiving unit receiving a trigger profile including predetermined zone information and a triggering rule about the generation of an alarm signal at the moment of entering and exiting of the predetermined zone, a location identifying unit locating a present location, a zone in/out detection unit generating the alarm signal according to the triggering rule based on the trigger profile and the present location located by the location identifying unit when entering the predetermined zone or exiting the predetermined zone, and a transmission unit transmitting the present location information identified by the location identifying unit when the alarm signal is generated.

Claims

1. An apparatus for locating a mobile device, the apparatus comprising:

a receiving unit receiving a trigger profile including predetermined zone information and a triggering rule about the generation of an alarm signal at the moment of entering and exiting of the predetermined zone;

a location identifying unit locating a present location;

a zone in/out detection unit generating the alarm signal according to the triggering rule based on the trigger profile and the present location located by the location identifying unit when entering the predetermined zone or exiting the predetermined zone; and

a transmission unit transmitting the present location information identified by the location identifying unit when the alarm signal is generated.

2. The apparatus of claim 1, wherein the location identifying unit comprises an RFID tag signal reader.

3. The apparatus of claim 1, wherein the location identifying unit identifies the present location based on a signal received from a GPS satellite.

4. The apparatus of claim 1, wherein the transmission unit controls a transmission time interval and a transmission velocity when transmitting the present location.

5. The apparatus of claim 1, further comprising a location information database unit which stores the present location information accumulatively transmitted from the transmission unit when the alarm signal is generated.

6. A method for locating a mobile device, the method comprising:

receiving a trigger profile including predetermined zone information and a triggering rule about the generation of an alarm signal at a moment of the entering and exiting of the predetermined zone;

locating a present location;

determining whether the located present location is moved into the predetermined zone from the outside of the predetermined zone or moved from the predetermined zone to the outside of the predetermined zone;

generating an alarm signal according to the triggering rule when the present location is moved into the predetermined zone or moved out of the predetermined zone; and

transmitting the located present location with the alarm signal when the alarm signal is generated.

7. The method of claim 6, wherein the locating of the present location further comprises locating a location using an RFID tag.

8. The method of claim 6, wherein, in the locating of the present location, the present location is located based on a signal received from a GPS satellite.

9. The method of claim 6, further comprising managing records of transmission of the located present location information accumulatively when the alarm signal is generated.
