Abstract

A system and method for locating mobile telephone devices via the Web. The mobile telephone device obtains and provides its location to a Web server in GPS latitude and longitude format. The communication between the Web server and the mobile telephone device may be through a browser or through mobile originated short message service. The Web server records the location information along with the time of receipt. Over time, the Web server may record several locations for a single mobile telephone device so that the progress of the mobile unit may be mapped. The information contained in the Web server is accessible to devices with Web browsing capabilities. A Web browsing device queries the Web server for location information pertaining to a particular mobile telephone device. The Web server may require authorization for such information before sending the location to the requesting device. The location information may be sent in a text only format or as text with graphics, depending on the display capabilities of the requesting Web browsing device.

Claims

1. A method of locating a mobile telephone device via the Web, comprising:

at the mobile telephone device, selecting to publish the location of the mobile device, acquiring the GPS location of the mobile device, and sending the GPS location to a Web server;

at the Web server, recording the GPS location and the time the GPS location was received, receiving a request for the GPS location of the mobile device from a Web browsing device, and sending the GPS location to the browsing device; and

at the browsing device, requesting the location of the mobile device from the Web server, receiving the mobile device location, and displaying the mobile device location.

2. A method as claimed in claim 1 and further comprising:

at the Web server, authorizing the browsing device before sending the GPS location of the mobile device to the browsing device.

3. A method as claimed in claim 1 wherein the browsing device is a wireless communications device.

4. A method as claimed in claim 3 wherein the browsing device is a digital cellular telephone.

5. A method as claimed in claim 1 wherein the acquiring and sending steps performed by the mobile device are automatically repeated after predetermined time intervals.

6. A method as claimed in claim 5 wherein the selecting step comprises selecting the predetermined time interval.

7. The method claim 1, wherein said selecting comprises using a user interface.

8. The method of claim 7, wherein said user interface comprises a browser.

10. A method as claimed in claim 7 wherein the Web server automatically sends queries to the mobile device after predetermined time intervals.

11. A method as claimed in claim 7 wherein the Web server requires authentication from the browsing device prior to sending the latitude and longitude of the mobile device.

13. A system as claimed in claim 10 locator and sender acquire and send the GPS location of the mobile device automatically and repeatedly after predetermined time intervals.

9. A method of locating a mobile telephone device connected to a Web server via a wireless communications network, comprising:

at the mobile telephone device, receiving a query from the Web server requesting the location of the mobile unit device, obtaining the latitude and longitude of the mobile device, and transmitting the latitude and longitude to the Web server;

at the Web server, sending the query to the mobile device, receiving the latitude and longitude of the mobile device in response to the query, recording the latitude and longitude and the time that it was received, receiving a request from a Web browsing device for the latitude and longitude of the mobile device, and sending the latitude and longitude to the browsing device; and

at the Web browsing device, requesting the latitude and longitude of the mobile device from the Web server, receiving the latitude and longitude, and displaying the latitude and longitude.

12. A tracking system comprising a mobile telephone device connected to a Web server by a wireless network, and a browser capable device connected to the Web server through a network wherein:

the mobile telephone device comprises a selector for selecting to send location information to the Web server, a locator for acquiring the GPS location of the mobile device, and a sender for sending the GPS location to the Web server;

the Web server comprises a receiver for receiving the GPS location of the mobile device and for receiving a query for the GPS location from the browser capable device, a recorder for recording the GPS location and time of receipt, and a transmitter for transmitting the GPS location to the browser capable device in response to the query for the GPS location; and

the browser capable device comprises a requestor for requesting the GPS location of the mobile device from the Web server, and a displayer for displaying the GPS location of the mobile device transmitted by the Web server.
