Abstract

The present disclosure relates to a method and an electronic device for measuring a position of the electronic device. The method includes identifying radio stations of different communication networks based on different communication signals transmitted from the radio stations, identifying at least one grid in a plurality of grids corresponding to the identified radio stations, and identifying the position of the electronic device based on the identified at least one grid, wherein the plurality of grids correspond to a plurality of areas generated on a basis of intensities of the different communication signals.

Claims

1. A method of an electronic device for measuring a position of the electronic device, the method comprising:

based on a received first communication signal corresponding to a first communication method, identifying a serving, radio station accessed by the electronic device from first radio stations transmitting the first communication signal;

determining whether a predetermined number or more of neighbor radio stations are identified from the first radio stations;

in response to determining that the predetermined number or more of neighbor radio stations are not identified, receiving a second communication signal corresponding to a second communication method different from the first Communication method, and based on the received second communication signal, identifying one or more second radio stations transmitting the second communication signal;

identifying at least one grid corresponding to the identified serving radio station included in the first radio stations and the identified one or more second radio stations from a plurality of grids; and

determining one grid associated with the position of the electronic device from the at least one grid by comparing an intensity of the first communication signal corresponding to each grid of the at least one grid with an intensity of the first communication signal received by the electronic device and comparing an intensity of the second communication signal corresponding to each grid of the at least one grid with an intensity of the second communication signal received by the electronic device.

2. The method of claim 1, wherein identifying the position of the electronic device comprises:

when the identified at least one grid corresponds to one grid, identifying the one grid as the one grid associated with the position of the electronic device.

3. The method of claim 1, wherein determining whether the predetermined number or more of neighbor radio station are identified comprises:

identifying the predetermined number or more of neighbor radio stations according to a request for searching for the neighbor radio stations transmitting the first communication signal.

4. The method of claim 1, wherein identifying the one or more second radio stations further comprises:

identifying the one or more second radio stations according to a request for searching for the one or more second radio stations transmitting the second communication signal.

5. The method of claim 1, wherein determining the one grid associated with the position of the electronic device from the at least one grid further comprises:

calculating a first differential value between the intensity of the first communication signal corresponding to each arid and the intensity of the first communication signal received by the electronic device;

calculating, a second differential value between the intensity of the second communication signal corresponding to each grid and the intensity of the second communication signal received by the electronic device;

and

extracting a grid in which the first differential value and the second differential value is the smallest as the one grid associated with the position of the electronic device.

6. The method of claim 1, wherein the first communication method comprises a LTE (Long Term Evolution) communication method, and

wherein the second communication method comprises a Wi-Fi (Wireless Fidelity) communication method.

7. An electronic device for measuring a position of the electronic device, the electronic device comprising:

a controller configured to;

based on a received first communication signal corresponding to a first communication method, identify a serving radio station accessed by the electronic device from first radio stations transmitting the first communication signal;

determine whether a predetermined number or more of neighbor radio stations are identified from the first radio stations;

in response to determining that the predetermined number or more of neighbor radio stations are not identified, receive a second communication signal corresponding to a second communication method different from the first communication method, and based on the received second communication signal, identify one or more second radio stations transmitting the second communication signal;

identify at least one grid corresponding to the identified serving radio station included in the first radio stations and the identified one or more second radio stations from a plurality of grids; and

determine one grid associated with the position of the electronic device from the at least one grid by comparing an intensity of the first communication signal corresponding to each grid of the at least one grid with an intensity of the first communication signal received by the electronic device and comparing an intensity of the second communication signal corresponding to each grid of the at least one grid with an intensity of the second communication signal received by the electronic device.

8. The electronic device of claim 7, wherein the controller is further configured to:

when the identified at least one grid corresponds to one grid, identify the one grid as the one grid associated with the position of the electronic device.

9. The electronic device of claim 7, wherein the controller identifies the predetermined number or more of neighbor radio stations from the first radio stations or the one or more second radio stations according to a request for searching for the predetermined number or more of neighbor radio stations or the one or more second radio stations.

10. The electronic device of claim 7, wherein the controller is further configured to:

calculate a first differential value between the intensity of the first communication signal corresponding to each grid and the intensity of the first communication signal received by the electronic device;

calculate a second differential value between the intensity of the second communication signal corresponding to each grid and the intensity of the second communication signal received by the electronic device; and

extract a grid in which the first differential value and second differential value is the smallest as the one grid associated with the position of the electronic device.
