Abstract

An embodiment of the disclosure provides an apparatus that include a communication module, a memory, a processor operatively connected to at least one of the communication module or the memory. The processor may be configured to perform UWB communication with a plurality of anchors included in a vehicle via the communication module according to a first scheme, to determine whether a distance to the vehicle falls within a predetermined distance by measuring the distance via the UWB communication, to determine whether a predetermined condition is satisfied if the distance falls within the predetermined distance, and if the predetermined condition is satisfied, to change the UWB communication scheme from the first scheme to a second scheme. Other embodiments are possible.

First claim

What is claimed is:

1. An electronic device comprising:
a communication module;
memory storing instructions; and
a processor,
wherein the instructions, when executed by the processor, cause the electronic device to:
perform UWB communication with a plurality of anchors included in a vehicle via the communication module according to a first scheme,
determine whether a predetermined condition for determining that the electronic device is located inside the vehicle is satisfied, and
change, based on determining that the predetermined condition is satisfied, UWB communication scheme from the first scheme to a second scheme,
wherein determining whether the predetermined condition is satisfied is based on a first distance between the electronic device and a first anchor of the plurality of anchors, a second distance between the electronic device and a second anchor of the plurality of anchors, and an anchor distance between the first anchor and the second anchor.

2. The electronic device of claim 1 , wherein the instructions, when executed by the processor, cause the electronic device to:
determine that predetermined condition is satisfied, when a maximum value among the first distance and the second distance is less than the anchor distance.

3. The electronic device of claim 2 , wherein, the instructions, when executed by the processor, cause the electronic device to determine that predetermined condition is not satisfied, when the maximum value among the first distance and the second distance is greater than or equal to the anchor distance.

4. The electronic device of claim 3 , wherein the instructions, when executed by the processor, cause the electronic device to determine that the electronic device is located inside the vehicle when the maximum value among the first distance and the second distance is less than the anchor distance, or determine that the electronic device is located outside the vehicle when the maximum value among the first distance and the second distance is greater than or equal to the anchor distance.

5. The electronic device of claim 1 , wherein the first scheme is a two way ranging (TWR) scheme, and the second scheme is a time difference of arrival (TDOA) scheme.

6. The electronic device of claim 1 , wherein the instructions, when executed by the processor, cause the electronic device to:
determine whether the predetermined condition is satisfied while performing the UWB communication with the plurality of anchors included in the vehicle according to the second scheme, and
when the predetermined condition is not satisfied, change the UWB communication scheme from the second scheme to the first scheme.

7. An operation method of an electronic device, the method comprising:
performing UWB communication with a plurality of anchors included in a vehicle via a communication module of the electronic device according to a first scheme;
determining whether a predetermined condition for determining that the electronic device is located inside the vehicle is satisfied; and
changing, based on determining that the predetermined condition is satisfied, UWB communication scheme from the first scheme to a second scheme,
wherein determining whether the predetermined condition is satisfied is based on a first distance between the electronic device and a first anchor of the plurality of anchors, a second distance between the electronic device and a second anchor of the plurality of anchors, and an anchor distance between the first anchor and the second anchor.

8. The method of claim 7 , wherein the determining of whether the predetermined condition is satisfied further comprises:
determining that the predetermined condition is satisfied, when a maximum value among the first distance and the second distance is less than the anchor distance.

9. The method of claim 8 , wherein the determining of whether the predetermined condition is satisfied further comprises determining that predetermined condition is not satisfied, when the maximum value among the first distance and the second distance is greater than or equal to the anchor distance.

10. The method of claim 9 , wherein the determining of whether the predetermined condition is satisfied further comprises determining that the electronic device is located inside the vehicle when the maximum value among the first distance and the second distance is less than the anchor distance, or determining that the electronic device is located outside the vehicle when the maximum value among the first distance and the second distance is greater than or equal to the anchor distance.

11. The method of claim 7 , wherein the first scheme is a two way ranging (TWR) scheme, and the second scheme is a time difference of arrival (TDOA) scheme.

12. The method of claim 7 , further comprising:
determining whether the predetermined condition is satisfied while performing the UWB communication with the plurality of anchors included in the vehicle according to the second scheme; and
when the predetermined condition is not satisfied, changing the UWB communication scheme from the second scheme to the first scheme.
