Abstract

A tracking method includes enabling a target device to obtain a location information thereof, and enabling the target device to generate a uniform resource locator (URL), which contains the location information obtained thereby and a location of an electronic map-containing webpage of a website. The electronic map-containing webpage contains an electronic map, and an indication of a location of the target device on the electronic map.

Claims

1. A tracking method, comprising:

A) enabling a target device to obtain a location information thereof;

B) enabling the target device to generate a uniform resource locator (URL), which contains the location information obtained thereby in step A) and a location of an electronic map-containing webpage of a website;

C) enabling the target device to send the URL generated thereby in step B) to a tracking device; and

D) enabling the tracking device to access the electronic map-containing webpage using the URL sent by the target device in step C), the electronic map-containing webpage containing an electronic map, and an indication of a location of the target device on the electronic map.

2. The tracking method as claimed in claim 1, wherein, in step C), the target device sends the URL to the tracking device via one of a short messaging service (SMS), a multimedia messaging service (MMS), and an electronic mail (e-mail).

3. The tracking method as claimed in claim 1, wherein, in step C), the target device sends the URL to the tracking device through a global system for mobile communications (GSM) telecommunication network.

4. The tracking method as claimed in claim 1, wherein the website is hosted by a server, and step D) further includes the sub-steps of:

d1) enabling the tracking device to access the electronic map-containing webpage using the URL; and

d2) enabling the server to create the electronic map-containing webpage based on the location information contained in the URL.

5. The tracking method as claimed in claim 4, wherein the server retrieves the electronic map from one of a database thereof and a database of another server.

6. The tracking method as claimed in claim 1, further comprising:

E) enabling the tracking device to issue a command to the target device prior to step A).

7. The tracking method as claimed in claim 6, wherein, in step E), the command is in the form of one of a missed call, a text message, and a dual-tone multi-frequency signal.

8. The tracking method as claimed in claim 6, wherein, in step E), the command contains a device identification (ID) of the tracking device, and in step A), the target device is enabled to verify the device ID of the tracking device such that the target device obtains the location information thereof only upon successful verification of the device ID of the tracking device.

9. The tracking method as claimed in claim 8, wherein the device ID of the tracking device is a phone number of the tracking device.
