Abstract

A method of locating a mobile device, and a mobile device utilizing the same are provided. The method, adopted by a wireless communication device, includes: searching for a plurality of signal-source types; in response to the searching, determining whether a first type of signal source is available; setting a search configuration based on availability of the first type of signal source; and searching again for the plurality of signal-source types according to the search configuration.

Claims

1. A method, adopted by a wireless communication device, comprising:

searching for a plurality of signal-source types;

in response to the searching, determining whether a first type of signal source is available;

setting a search configuration based on availability of the first type of signal source; and

searching again for the plurality of signal-source types according to the search configuration.

2. The method of 1, wherein the search configuration contains a first priority for searching for the first type of signal source;

and

the step of setting the search configuration comprises;

decreasing the first priority of searching for the first type of signal source when the first type of signal source is unavailable.

3. The method of 1, wherein the search configuration contains a first search status for searching for the first type of signal source;

and

the step of setting the search configuration comprises;

when the first type of signal source is unavailable, setting the first search status to off to stop searching for the first type of signal source.

4. The method of 1, wherein the step of setting the search configuration comprises:

setting the search configuration when first type of signal source is unavailable a predetermined number of times.

5. The method of 1, wherein the step of searching for the plurality of signal-source types comprises:

when second information of a second type of signal source has been changed from a previous search, searching for the plurality of signal-source types without the search configuration.

6. The method of 5, wherein the second information comprises device identifier and a signal strength of the second type of signal source.

7. The method of 1, wherein the step of searching for the plurality of signal-source types comprises:

when the wireless communication device is in motion, searching for the plurality of signal-source types without the search configuration.

8. The method of 1, wherein the first signal is a GPS signal, the first type of signal source is a GPS satellite.

9. The method of 1, wherein the first signal is a WiFi or Bluetooth signal, the first type of signal source is a WiFi or Bluetooth Access Point (AP).

10. A wireless communication device, comprising:

a searching circuit, configured to search for a plurality of signal-source types;

a signal type identification circuit, in response to the searching, configured to determine whether a first type of signal source is available; and

a search configuration circuit, configured to set a search configuration based on availability of the first type of signal source;

wherein the searching circuit is configured to search again for the plurality of signal-source types according to the search configuration.

11. The wireless communication device of 10, further comprising:

a memory, configured to store the search configuration which contains a first priority for searching for the first type of signal source;

wherein the search configuration circuit is configured to decrease the first priority of searching for the first type of signal source when the first type of signal source is unavailable.

12. The wireless communication device of 10, wherein the search configuration contains a first search status for searching for the first type of signal source;

and

when the first type of signal source is unavailable, the search configuration circuit is configured to set the first search status to off to stop searching for the first type of signal source.

13. The wireless communication device of 10, wherein when the first type of signal source is unavailable a predetermined number of times, the search configuration circuit is configured to set the search configuration.

14. The wireless communication device of 10, wherein:

when second information of a second type of signal source has been changed from a previous search, the searching circuit is configured to search for the plurality of signal-source types without the search configuration.

15. The wireless communication device of 14, wherein the second information comprises device identifier and a signal strength of the second type of signal source.

16. The wireless communication device of 10, wherein when the wireless communication device is in motion, the searching circuit is configured to search for the plurality of signal-source types without the search configuration.

17. The wireless communication device of 10, wherein the first signal is a GPS signal, the first type of signal source is a GPS satellite.

The wireless communication device of 10, wherein the first signal is a WiFi or Bluetooth signal, and the first type of signal source is a WiFi or Bluetooth Access Point (AP).
