Abstract

A wireless location tracking device (WLTD) includes a global position system (GPS) for receiving signals and generating data for determining a geographic location of the wireless location tracking device (WLTD). The WLTD further includes a transceiver for receiving an incoming call from a caller requesting a location of the wireless location tracking device. A processor includes a map database for receiving and applying data from the GPS to determine a geographic location of the WLTD in reference to the map database. The processor further controls the transceiver to automatically call back the caller for transmitting a short message to indicate the geographic location of the WLTD.

Claims

5. A wireless location tracking device (WLTD) comprising a processor and a transceiver for receiving geographic signals and receiving/transmitting communication signals;

said WLTD further comprising;

a map database providing map data to said processor to determine a location of said WLTD on a map according to said map database.

6. The wireless location tracking device (WLTD) of claim 5 further comprising:

a battery for supplying power to said processor and said transceiver.

7. The wireless location tracking device (WLTD) of claim 5 wherein:

said transceiver further comprising a GSM chip operated with a SIM card.

8. The wireless location tracking device (WLTD) of claim 5 wherein:

said processor further includes a global position system (GPS) chip for generating coordinates applicable by said processor in reference to said map database to generate said location of said WLTD on said map.

15. The method of claim 8 further wherein:

said step of automatically responding to said call to process location data including the latitude and longitude coordinate data in reference to the map database further comprising a step of automatically activating said processor to process said location data and generating a short message to indicate a location of said wireless location tracking device and automatically activate a transceiver to call back to a caller of said call for sending said short message without human actions for any of above described processes.

9. A method to determine a location of wireless location tracking device comprising:

integrating a wireless communication transceiver with a geographic location determination processor including a map database for automatically responding to a call to process location data including the latitude and longitude coordinate data in reference to the map database.

1. A wireless location tracking device (WLTD) comprising:

a global position system (GPS) for receiving signals and generating data for determining a geographic location of said wireless location tracking device (WLTD);

a transceiver for receiving an incoming call from a caller requesting a location of said wireless location tracking device;

a processor including a map database for receiving and applying data from said GPS to determining a geographic location of said WLTD in reference to said map database; and

said processor further controls said transceiver to automatically call back said caller for transmitting a short message to indicate the geographic location of said WLTD.

2. The wireless location tracking device (WLTD) of claim 1 further comprising:

a battery for supplying power to said GPS, said transceiver and said processor.

3. The wireless location tracking device (WLTD) of claim 1 wherein:

said transceiver further comprising a GSM chip operated with a SIM card.

4. The wireless location tracking device (WLTD) of claim 1 wherein:

said GPS further generating coordinates applicable by said processor in reference to said map database to generate said geographic location of said WLTD.

10. The method of claim 9 further comprising:

receiving a wireless location enquiry message from the communication device and automatically responding to the wireless location enquiry message by processing a device location message and transmitting the location message back to the communication device to indicate the geographic location of the wireless location tracking device.

11. The method of claim 9 further comprising:

checking a phone number of the communication device sending the wireless location inquiry message to determine if said phone number of said communication device is an authorized phone number for transmitting the location message back to the communication device with the authorized phone number to indicate the geographic location of the wireless location tracking device.

12. The method of claim 9 further wherein:

said step of automatically responding to said call to process location data including the latitude and longitude coordinate data in reference to the map database further comprising a step of applying a database manager for processing said coordinate data in reference to said map database for generating short message including physical address, major cross street, famous buildings, landmarks, train station or bus station near said location of said wireless location tracking device.

14. The method of claim 9 further wherein:

said step of automatically responding to said call to process location data including the latitude and longitude coordinate data in reference to the map database further comprising a step of automatically activating said processor to process said location data and generating a short message to indicate a location of said wireless location tracking device and automatically activate a transceiver to call back to a caller of said call for sending said short message without making an audio or visual indication of any of above described processes.

16. The method of claim 9 further comprising:

connecting a battery for supplying power to said wireless communication transceiver and said geographic location determination processor.

10-1. The method of claim 9 further comprising:

checking a phone number of the communication device sending the wireless location inquiry message before processing and responding to the wireless location inquiry message.
