Abstract

An embodiment provides a method, including: a first electronic device receiving a location signal through a communication module of the first electronic device; the first electronic device storing information of said location signal; the first electronic device transmitting the information of said location signal to a second electronic device in communication with the first electronic device, so that the second electronic device can derive a location of the first electronic device based on the information of said location signal; the first electronic device receiving from the second electronic device, information comprising said location of the first electronic device, via the communication module of the first electronic device; and the first electronic device displaying said location of the first electronic device. Other embodiments are described and claimed.

Claims

1. A method, comprising:

a first electronic device receiving a location signal through a communication module of the first electronic device;

the first electronic device storing information of said location signal;

the first electronic device transmitting the information of said location signal to a second electronic device in communication with the first electronic device, so that the second electronic device can derive a location of the first electronic device based on the information of said location signal;

the first electronic device receiving from the second electronic device, information comprising said location of the first electronic device, via the communication module of the first electronic device;

the first electronic device displaying said location of the first electronic device; and

the first electronic device determining a remaining power level of a power source of the first electronic device, wherein the first electronic device determining the remaining power level of the power source comprises;

acquiring a remaining battery power value of the first electronic device;

determining if the remaining battery power value is lower than a preset value; and

responsive to a determination that the battery power value is lower than a preset value, placing the first electronic device into a low power consumption mode; and

responsive to a determination that the battery power value is higher than the preset value, placing the first electronic device into a high power consumption mode;

wherein the step of the first electronic device transmitting the information of said location signal to a second electronic device occurs only responsive to the determination that the battery power value is lower than the preset value.

2. The method of claim 1, wherein transmitting takes place in real time.

3. The method of claim 1, wherein the transmitting takes place during a preset time interval.

4. The method of claim 1, further comprising:

storing the location signal received by the first electronic device during movement of the first electronic device.

5. The method of claim 4, wherein, in response to the first electronic device stopping, the first electronic device transmits the information to the second electronic device.

6. The method of claim 1, further comprising:

acquiring map information; and

using the map information to display said location of the first electronic device.

7. The method of claim 6, wherein the step of acquiring the map information comprises receiving the map information from a remote device.

8. An electronic device, comprising:

a housing;

a display device disposed within the housing;

a communication module disposed within the housing;

a processor operatively coupled to the display device and the communication module; and

a memory that stores instructions executable by the processor to;

receive a location signal through the communication module;

store information of said location signal;

transmit the information to a second electronic device;

receive from the second electronic device, information comprising said location of the first electronic device via the communication module;

display said location of the first electronic device via the display device; and

determine a remaining power level of a power source of the first electronic device, wherein the instructions executable by the processor to determine the remaining power level comprise;

acquiring a remaining battery power value of the first electronic device;

determining if the remaining battery power value is lower than a preset value; and

responsive to a determination that the battery power value is lower than a preset value, placing the first electronic device into a low power consumption mode; and

responsive to a determination that the battery power value is higher than the preset value, placing the first electronic device into a high power consumption mode;

wherein the instructions executable by the processor to transmit comprise instructions executable by the processor to transmit the information to the second electronic device responsive to the determination that the battery power value is lower than the preset value.

9. The electronic device of claim 8, wherein the processor executes instructions to transmit the information in real time.

10. The electronic device of claim 8, wherein the processor executes instructions to transmit the information during a preset time interval.

11. The electronic device of claim 8, wherein the processor executes instructions to:

store the location signal during movement of the electronic device.

12. The electronic device of claim 11, wherein, in response to the electronic device stopping, the processor transmits the information to the second electronic device.

13. The electronic device of claim 8, wherein the processor executes instructions to:

acquire map information; and

use the map information to display said location of the electronic device on the display device.

14. An electronic device, comprising:

a processor; and

a memory that stores instructions executable by the processor to;

receive positioning data from a mobile device;

process the positioning data to resolve a location of the mobile device;

transmit, to the mobile device, information comprising said location of the mobile device; and

determine a remaining power level of a power source of the mobile device, wherein the instructions executable by the processor to determine the remaining power level comprise;

acquiring a remaining battery value of the mobile device;

determining if the remaining battery power value is lower than a preset value; and

responsive to a determination that the battery power value is lower than a preset value, placing the mobile device into a low power consumption mode; and

responsive to a determination that the battery power value is higher than the preset value, placing the mobile device into a high power consumption mode;

wherein the instructions executable by the processor to receive comprise instructions executable by the processor to receive the information from the mobile device responsive to the determination that the battery power value is lower than the preset value.
