Abstract

The present invention relates to a method for controlling a first device performed by a control device using the Bluetooth. The present invention provides a method and apparatus including receiving a first advertising message from a first device; calculating a first distance value that indicates a distance with the first device based on the first advertising message; receiving a second advertising message from a second device when the first distance value is smaller than a threshold value preconfigured to determine a proximity with the control device; and calculating a second distance value that indicates a distance with the second device based on the second advertising message, where a Bluetooth connection is established between the first device and the second device when the second distance value is smaller than the threshold value.

Claims

1. A method for controlling a second device performed by a control device using a Bluetooth communication, the method comprising:

establishing a Bluetooth connection with a first device;

receiving, from the first device, a first token generated using first user information that indicates a first user of the first device;

establishing a Bluetooth connection with a second device;

exchanging the first token and, a second token stored in the second device with the second device,

wherein the second token is generated using second user information that indicates a second user registered in the second device;

transmitting a control message instructing a specific operation to the second device when the user identified by the first token and the user identified by the second token match,

wherein a range of control authorization for the second device is determined based on a value of the first token,

wherein a distance between the first device and the second device is periodically calculated by the first device,

wherein the distance between the first device and the second device is calculated using Received Signal Strength Indication (RSSI), and

wherein the control authorization for the second device is released when the distance between the first device and the second device is less than a first threshold value.

2. The method of claim 1,

wherein the first token is transmitted from the first device when a first distance value that indicates a distance between the first device and the control device is smaller than a second threshold value preconfigured in the first device, and

wherein the second threshold value is a value for determining a proximity with the first device.

3. A control device for controlling a second device using a Bluetooth communication, the control device comprising:

a communication unit for communicating to an external device; and

a processor functionally connected to the communication unit,

wherein the processor is configured to;

establish a Bluetooth connection with a first device;

receive, from the first device, a first token generated using first user information that indicates a first user of the first device;

establish a Bluetooth connection with a second device;

exchange the first token and, a second token stored in the second device with the second device,

wherein the second token is generated using second user information that indicates a second user registered in the second device; and

transmit a control message instructing a specific operation to the second device when the user identified by the first token and the user identified by the second token match,

wherein a range of control authorization for the second device is determined based on a value of the first token,

wherein a distance between the first device and the second device is periodically calculated by the first device,

wherein the distance between the first device and the second device is calculated using Received Signal Strength Indication (RSSI), and

wherein the control authorization for the second device is released when the distance between the first device and the second device is less than a first threshold value.

4. The control device of claim 3,

wherein the first token is transmitted from the first device when a first distance value that indicates a distance between the first device and the control device is smaller than a second threshold value preconfigured in the first device, and

wherein the second threshold value is a value for determining a proximity with the first device.
