Abstract

An electronic device including a memory storing instructions; and a processor that executes the instructions to perform a process including: identifying a registered device through a scan, after identifying the registered device, connecting with the registered device based on identification information of the registered device and a preset password, to establish a communication connection with the registered device, requesting, through the established communication connection, infrared codeset information from the registered device, and after receiving the requested infrared codeset information from the registered device, transmitting, to the registered device through the established communication connection, a request for authentication of the registered device, and transmitting, to the registered device over infrared light, an authentication signal including the infrared codeset information, for authenticating the registered device.

First claim

What is claimed is:

1. A method performed by an electronic device, the method comprising:
identifying a registered device through a scan;
after identifying the registered device, connecting with the registered device based on identification information of the registered device and a preset password, to establish a communication connection with the registered device;
requesting, through the established communication connection, infrared codeset information from the registered device; and
after receiving the requested infrared codeset information from the registered device,
transmitting, to the registered device through the established communication connection, a request for authentication of the registered device, and
transmitting, to the registered device over infrared light, an authentication signal including the infrared codeset information, for authenticating the registered device.

2. The method of claim 1 , further comprising:
in response to success in authenticating the registered device, receiving, from the registered device through the established communication connection, an authentication success signal;
after receiving the authentication success signal,
transmitting, to the registered device through the established communication connection, information needed for connection of the registered device to a first external device, and
transmitting, through the established communication connection, information needed for registration of the registered device in a second external device.

3. The method of claim 2 , further comprising:
after transmitting the information needed for connection of the registered device to the first external device and the information needed for registration of the registered device in the second external device, terminating the established communication connection with the registered device.

4. The method of claim 1 , further comprising:
in response to failure in authenticating the registered device, controlling the electronic device to output, on a screen, a user interface via which authentication of the registered device is performable by a user.

5. The method of claim 4 , further comprising:
in response to receiving, from the registered device through the established communication connection, an authentication failure signal, or when not receiving any response from the registered device for a preset time, determining that authentication of the registered device has failed.

6. The method of claim 1 , wherein the established communication connection uses one of Wi-Fi communication, Bluetooth communication, Bluetooth low energy communication, and ZigBee communication.

7. The method of claim 1 , wherein the infrared codeset information is information corresponding to a button, for authentication, of the registered device.

8. The method of claim 1 , wherein the authentication signal further includes:
information of a preset region of media access control (MAC) of the electronic device, and
infrared-type information indicating that the authentication signal is an infrared signal for device authentication.

9. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the method of claim 1 .

10. An electronic device comprising:
a memory storing instructions; and
a processor that executes the instructions to perform a process including:
identifying a registered device through a scan,
after identifying the registered device, connecting with the registered device based on identification information of the registered device and a preset password, to establish a communication connection with the registered device,
requesting, through the established communication connection, infrared codeset information from the registered device, and
after receiving the requested infrared codeset information from the registered device,
transmitting, to the registered device through the established communication connection, a request for authentication of the registered device, and
transmitting, to the registered device over infrared light, an authentication signal including the infrared codeset information, for authenticating the registered device.

11. The electronic device of claim 10 , wherein the process further includes:
in response to success in authenticating the registered device, receiving, from the registered device through the established communication connection, an authentication success signal, and
after receiving the authentication success signal,
transmitting, to the registered device through the established communication connection, information needed for connection of the registered device to a first external device, and
transmitting, through the established communication connection, information needed for registration of the registered device in a second external device.

12. The electronic device of claim 11 , wherein the process further includes:
after transmitting the information needed for connection of the registered device to the first external device and the information needed for registration of the registered device in the second external device, terminating the established communication connection with the registered device.

13. The electronic device of claim 10 , further comprising:
a display,
wherein the process further includes:
in response to failure in authenticating the registered device, control the electronic device to display a user interface on the display through which authentication of the registered device is performable by a user.

14. The electronic device of claim 13 , wherein the process further includes:
in response to receiving, from the registered device through the established communication connection, an authentication failure signal, or when not receiving any response from the registered device for a preset time, determining that authentication of the registered device has failed.

15. The electronic device of claim 10 , wherein the established communication connection uses one of Wi-Fi communication, Bluetooth communication, Bluetooth low energy communication, and ZigBee communication.

16. The electronic device of claim 10 , wherein the infrared codeset information comprises information corresponding to a button, for authentication, of the registered device.

17. The electronic device of claim 10 , wherein the authentication signal further includes information of a preset region of media access control (MAC) information of the electronic device, and infrared-type information indicating that the authentication signal is an infrared signal for device authentication.

18. A system comprising:
an electronic device; and
a registered device,
wherein the electronic device is configured to perform a process including:
identifying the registered device through a scan,
after identifying the registered device, connecting with the registered device based on identification information of the registered device and a preset password, to establish a communication connection with the registered device,
requesting, through the established communication connection, infrared codeset information from the registered device, and
after receiving the requested infrared codeset information from the registered device,
transmitting, to the registered device through the established communication connection, a request for authentication of the registered device, and
transmitting, to the registered device over infrared light, an authentication signal including the infrared codeset information,
