Abstract

An electronic device according to various embodiments of the present disclosure comprises: at least one wireless communication module; and a processor, wherein the processor can control the wireless communication module to respectively receive a plurality of pieces of data from a plurality of external electronic devices, identify a time when each of the plurality of pieces of data has been received, and, when location information regarding the plurality of external electronic devices is included in the plurality of pieces of data, calculate the location of the electronic device by using a time difference in reception of the plurality of pieces of data and the location information regarding the plurality of external electronic devices. Various other embodiments are also possible.

First claim

What is claimed is:

1. An electronic device comprising:
at least one wireless communication interface;
a memory; and
at least one processor operably connected to the at least one wireless communication interface and the memory, wherein the memory stores instructions executable by the at least one processor, which, when executed, cause the electronic device to:
control the wireless communication interface to receive data from a plurality of external electronic devices, respectively,
identify reception time instances of the data received, respectively, from the plurality of the external electronic devices,
calculate a location of the electronic device using: a) a time difference of arrival (TDOA) identified based on the reception time instances of the data received, respectively, from the plurality of the external electronic devices and b) location information for the plurality of the external electronic devices when the data comprises the location information for the plurality of the external electronic devices, and
determine another reception time instance of next data based on the reception time instances of the data received from the plurality of the external electronic devices and transmission time instances of the data that are determined when the plurality of the external electronic devices transmits the data, respectively.

2. The electronic device of claim 1 , wherein the data includes a scrambled timestamp sequence (STS) code.

3. The electronic device of claim 1 , wherein the memory stores instructions, which, when executed, cause the electronic device to:
when the data does not comprise the location information for the plurality of the external electronic devices, control the wireless communication interface to transmit, to a server, information for calculating the location of the electronic device; and
receive, from the server, location information for the electronic device.

4. The electronic device of claim 3 , wherein the transmitted information for calculating the location of the electronic device comprises identification information for the plurality of the external electronic devices and the TDOA.

5. An operating method of an electronic device, the method comprising:
receiving first data from a plurality of external electronic devices, respectively;
identifying reception time instances of the data received, respectively, from the plurality of the external electronic devices;
calculating a location of the electronic device using: a) a time difference of arrival (TDOA) identified based on the reception time instances of the data received, respectively, from the plurality of the external electronic devices and b) location information for the plurality of the external electronic devices when the data comprises the location information for the plurality of the external electronic devices; and
determining another reception time instance of next data based on the reception time instance of the data from the plurality of the external electronic devices and transmission time instances of the data that are determined when the plurality of external electronic devices transmits the data, respectively.

6. The operating method of claim 5 , wherein the data includes a scrambled timestamp sequence (STS) code.

7. The operating method of claim 5 , further comprising:
transmitting, to a server, information for calculating the location of the electronic device when the data does not comprise the location information for the plurality of external electronic devices; and
receiving, from the server, location information for the electronic device.

8. The operating method of claim 7 , wherein the transmitted information for calculating the location of the electronic device comprises identification information for the plurality of external electronic devices and the TDOA.
