Abstract

The present invention relates to a method and an apparatus for estimating, by a third device, a location of a first device by using a Bluetooth low energy (LE) technique. The present invention provides a method and an apparatus, the method comprising the steps of: receiving, from the third device, a location measurement request message for requesting a measurement of the location of the first device; transmitting, to the first device, a first request message for requesting location information relating to the location of the first device; receiving, from the first device, a first response message including the location information as a response to the request message; estimating location value information indicating the location of the first device on the basis of the location information; and transmitting, to the third device, a location measurement response message including the estimated location value information.

First claim

1 . A method for estimating a position of a first device by a third device using a Bluetooth low energy (BLE), the method, being performed in a second device, comprising:
receiving a location measurement request message requesting measurement of a location of the first device from the third device; transmitting a first request message requesting activation of a position measurement function for measuring the position of the first device to the first device; receiving a first response message in response to the first request message from the first device; calculating an angle with the first device based on the first response message; estimating position value information indicating a position of the first device based on the calculated angle; and transmitting a location measurement response message including the estimated position value information to the third device.

2 . The method of claim 1 ,
wherein the position measurement request message includes at least one of ID information indicating the first device, address information, or type information indicating a type of the first device, and wherein the location value information includes at least one of latitude information, longitude information, altitude information for the first device, or transmission signal strength information indicating strength of a transmitted signal.

3 . (canceled)

4 . The method of claim 1 , wherein the position measurement request message is transmitted in a unicast method or broadcast method.

5 . The method of claim 4 , further comprising:
when the position measurement request message is transmitted in the unicast method, receiving a connection request message for Bluetooth connection from the third device; and establishing Bluetooth connection with the third device based on the connection request message.

6 . The method of claim 1 , further comprising:
receiving a control message for requesting a specific operation from the third device to the second device; performing the specific operation based on the control message; and transmitting a second response message in response to the control message to the third device.

7 . The method of claim 6 , wherein the specific operation is an operation of setting an interval at which the request message is transmitted.

8 . The method of claim 1 , further comprising:
receiving a second request message requesting connection information or state information of the second device from the third device; and transmitting a second response message including at least one of the connection information or state information as a response with respect to the second request message to the third device.

9 . The method of claim 1 , further comprising:
receiving a control message for requesting a specific operation from the third device to the first device; and transmitting the control message to the first device.

10 . A device, as a second device in which a third device estimates a position of a first device using Bluetooth low energy (BLE), the device comprising:
a communication unit communicating with the outside wirelessly or wiredly; and a processor functionally connected to the communication unit, wherein the processor is configured to:
receive a position measurement request message requesting measurement of a position of the first device from the third device;
transmit a first request message requesting activation of a position measurement function for measuring the position of the first device to the first device;
receive a first response message in response to the first request message from the first device;
calculate an angle with the first device based on the first response message;
estimate position value information indicating a position of the first device based on the calculated angle; and
transmit a position measurement response message including the estimated position value information to the third device.

11 . The device of claim 10 ,
wherein the position measurement request message includes at least one of ID information indicating the first device, address information, or type information indicating a type of the first device, and wherein the location value information includes at least one of latitude information, longitude information, altitude information for the first device, or transmission signal strength information indicating strength of a transmitted signal.

12 . (canceled)

13 . The device of claim 11 , wherein the position measurement request message is transmitted in a unicast method or broadcast method.

14 . The device of claim 13 , wherein when the position measurement request message is transmitted in the unicast manner, the processor is further configured to:
receive a connection request message for Bluetooth connection from the third device; and establish Bluetooth connection with the third device based on the connection request message.

15 . The device of claim 10 , wherein the processor is further configured to:
receive a control message for requesting a specific operation from the third device to the second device; perform the specific operation based on the control message; and transmit a second response message in response to the control message to the third device.

16 . The device of claim 15 , wherein the specific operation is an operation of setting an interval at which the request message is transmitted.

17 . The device of claim 11 , wherein the processor is further configured to:
receive a second request message requesting connection information or state information of the second device from the third device; and transmit a second response message including at least one of the connection information or state information as a response with respect to the second request message to the third device.

18 . The device of claim 11 , wherein the processor is further configured to:
receive a control message for requesting a specific operation from the third device to the first device; and transmit the control message to the first device.

19 . The method of claim 1 , further comprising:
receiving an additional request message from the third device requesting addition of the second device to list information indicating devices for which the first device measures a position; and adding the second device to the list information.

20 . The device of claim 10 , wherein the processor is further configured to:
receive an additional request message from the third device requesting addition of the second device to list information indicating devices for which the first device measures a position; and add the second device to the list information.
