The electronic device 10 according to an embodiment may perform a secure connection with the external device 20 based on a signal received from the external device 20, and the external device 20 may be communicatively connected with a server 30 based on data received from the electronic device 10 which is securely connected. Here, a secure connection may mean a communication connection in which data is transmitted and received in an encrypted state. According to an example, the external device 20 may be communicatively connected, when information for communicatively connecting with the server 30 is received from the electronic device 10 which is securely connected, with the server 30 based on the received information.
According to an embodiment, the secure connection may be implemented with datagram transport layer security (DTLS) technology. DTLS may be an encryption protocol implemented with secure sockets layer (SSL) technology in a user datagram protocol (UDP), and the UDP may be a protocol used in a transport layer which is the fourth layer in an open systems interconnection (OSI) reference model developed with an international communication standard. Meanwhile, the SSL may mean a standard technology for protecting internet connection by encrypting data transmitted between a server corresponding to a website and a server corresponding to a browser. According to an example, the electronic device 10 may be securely connected with the external device 20 in a DTLS method based on the signal received from the external device 20. However, the embodiment is not limited thereto.
To perform the secure connection, the electronic device 10 or the external device 20 according to an embodiment may output an audio signal included with information for the secure connection. Based on the electronic device 10 according to an example outputting the audio signal, the external device 20 may perform the secure connection with the electronic device 10 by receiving the audio signal output from the electronic device 10. Alternatively, based on the external device 20 outputting the audio signal according to an example, the electronic device 10 may perform the secure connection with the external device 20 by receiving the audio signal output from the external device 20.
Meanwhile, if a distance between the electronic device 10 and the external device 20 is far or if a strength of the audio signal output from the electronic device 10 or the external device 20 is low, the communication connection between the electronic device 10 or the external device 20 may not be performed properly due to a strength of an audio received by the electronic device 10 or the external device 20 being small. Alternatively, if the strength of the audio signal output from the electronic device 10 or the external device 20 is high, another electronic device other than the electronic device 10 may receive a communication connection signal, and based therefrom, the external device 20 may be securely connected with another electronic device rather than the electronic device 10.

The electronic device 100 may communicatively connect with the external device and the external server through various methods. According to an embodiment, a communication module for communication with the external device and the external server may be identically implemented.

According to another embodiment, the communication modules for communication with the external device and the external server may be implemented separately. For example, the electronic device 100 may communicate with the external device using the Bluetooth module, and communication with the external server using an Ethernet modem or a Wi-Fi module.
The communication interface 110 may input and output data of various types. For example, the communication interface 110 may transmit and receive data of various types with an external device (e.g., source device), an external storage medium (e.g., USB memory), or an external server (e.g., WEBHARD) through communication methods such as, for example, and without limitation, an AP based Wi-Fi (e.g., Wi-Fi, wireless LAN network), Bluetooth, ZigBee, a wired/wireless local area network (LAN), a wide area network (WAN), Ethernet, IEEE 1394, a high-definition multimedia interface (HDMI), a universal serial bus (USB), a mobile high-definition link (MHL), Audio Engineering Society/European Broadcasting Union (AES/EBU), Optical, Coaxial, or the like.

For example, the communication interface 110 may use at least one from among an Ethernet module or the Wi-Fi module to communicate with the external server, and use the Bluetooth module to communicate with the external device. However, the above is merely one embodiment, and the communication interface 110 may use at least one communication module from among various communication modules when communicating with a plurality of external devices or external servers.
The one or more processors 120 (hereinafter, referred to as a ‘processor’) may control the overall operation of the electronic device 100 by being electrically connected with the communication interface 110. The processor may be configured with one or a plurality of processors. Specifically, the processor 120 may perform, by executing at least one instruction stored in memory (not shown), an operation of the electronic device 100 according to various embodiments of the disclosure.

The processor 120 according to an embodiment may be implemented as the digital signal processor (DSP), the microprocessor, or the time controller (TCON). However, the embodiment is not limited thereto, and may include one or more from among the central processing unit (CPU), the micro controller unit (MCU), the micro processing unit (MPU), the controller, the application processor (AP), the communication processor (CP), or the ARM processor, or may be defined by the corresponding term. In addition, the processor 120 may be implemented as the System on Chip (SoC) or the large scale integration (LSI) in which the processing algorithm is embedded, and may be implemented in the form of the field programmable gate array (FPGA).
According to an embodiment, the processor 120 may receive a signal for a secure connection from the external device. The external device 20 may be Internet of Things (IoT) device of various types such as, for example, and without limitation, an air conditioner, a speaker, a projector, an air purifier, a fan, a refrigerator, a robot, and the like according to an example. Meanwhile, the signal for the secure connection may include at least one from among information on a personal identification number (PIN) code for ownership authentication of the external device or function information of the external device according to an example, but is not limited thereto, and information on a personal identification number (PIN) code for ownership authentication of the electronic device 100 may be included. Meanwhile, the secure connection according to an example, may be a secure connection of a DTLS type.
According to an example, the processor 120 may receive an audio signal included with information on the personal identification number (PIN) code for ownership authentication of the external device, and the audio signal may be a signal of an inaudible frequency band. For example, the processor 120 may receive an audio signal for a secure connection through a microphone (not shown).
In addition, the processor 120 according to an example may receive a wireless communication signal included with function information of the external device through the communication interface 110. Here, the function information of the external device may be information on at least one from among at least one configuration included in the external device or a capability of the external device. For example, if a speaker and a microphone are included in the external device, information notifying that the speaker and the microphone are included in the function information of the external device may be included. However, the above is not limited thereto, and for example, information notifying that a sound source receiving function or a sound source transmitting function is included in the external device may be included.
Meanwhile, the wireless communication signal according to an example may be a signal of at least one type from among a Wireless-Fidelity (Wi-Fi) signal or a Bluetooth low energy (BLE) advertising signal. For example, the external device may broadcast a BLE advertising signal included with function information of the external device, and the processor 120 may receive the BLE advertising signal broadcasted from the external device through the communication interface 110.
Alternatively, for example, the external device may broadcast a soft access point (AP) advertising signal included with function information of the external device. The processor 120 may receive the soft AP advertising signal broadcasted from the external device through the communication interface 110, but is not limited thereto, and wireless communication signals or wired communication signals of different types may be received.
According to an embodiment, the processor 120 may identify, based on the signal for the secure connection being received, a received signal strength indicator (RSSI) value of the received signal. Here, the RSSI value may mean a strength of the received signal for the secure connection. According to an example, the processor 120 may identify, based on the audio signal included with information on the PIN code for ownership authentication of the external device being received, the RSSI value of the received audio signal. Alternatively, the processor 120 according to an example may identify, based on the wireless communication signal included with function information of the external device being received, the RSSI value of the received wireless communication signal.
According to an embodiment, the processor 120 may identify whether at least one from among the speaker or the microphone is included in the external device based on function information of the external device included in the received signal.
According to an embodiment, the processor 120 may transmit feedback information to the external device based on the identified RSSI value.
According to an example, the processor 120 may transmit, based on the speaker being identified as included in the external device based on function information of the external device included in the received signal, feedback information associated a strength of the RSSI value to the external device through the communication interface 110 based on the identified RSSI value. Here, the feedback information may mean information for changing a strength of a signal being transmitted from the external device for the strength of the signal received from the external device to be included in a pre-set range if the strength of the received signal is outside the pre-set range. Meanwhile, information on the pre-set range may be pre-stored in memory (not shown), or included in the wireless communication signal received from the external device.
For example, the processor 120 may transmit, based on the strength of the received audio signal being lower than a minimum value from among values corresponding to the pre-set range, feedback information for increasing the strength of the audio signal transmitted from the external device through the communication interface 110 to the external device. Alternatively, the processor 120 may transmit, based on the strength of the received audio signal being higher than the pre-set range, feedback information for reducing the strength of the audio signal transmitted from the external device through the communication interface 110 to the external device. Meanwhile, information on the pre-set range may be stored in memory (not shown) at an initial setting, but is not limited thereto, and may be obtained based on a user input according to an example.
If the strength of the received audio signal is smaller than a pre-set value, the processor 120 may not identify the audio signal. Because the above is a reason for lowering a success rate of the secure connection, the success rate of communication connection may increase so long as an audio signal having an RSSI size of greater than or equal to a pre-set value is received. In addition, if the strength of the received audio signal is greater than the pre-set value, communication connection with another electronic device other than the electronic device 100 present in a home may be carried out. Accordingly, the strength of the signal transmitted by the external device has to be included in the pre-set range in order to increase the success rate for the communication connection with the electronic device 100 present in the home.
Meanwhile, the processor 120 according to an embodiment may output an audio signal for the secure connection with the external device through a speaker (not shown). The above will be described in detail through
Meanwhile, the processor 120 according to an embodiment may receive an updated signal from the external device based on the feedback information. According to an example, if the feedback information which increases the strength of the audio signal being transmitted from the external device is transmitted to the external device, the processor 120 may receive an audio signal with the RSSI value being greater than or equal to the pre-set value from the external device through the communication interface 110.
According to an embodiment, the processor 120 may perform the secure connection with the external device based on the updated signal. According to an example, the processor 120 may perform, based on an audio signal of a strength changed based on the feedback information being received from the external device through the microphone (not shown), the secure connection with the external device based on the audio signal of the changed strength.
For example, the processor 120 may perform, based on an audio signal included with information on the PIN code for ownership authentication of the external device being received as a signal with the RSSI value being greater than or equal to the pre-set value, the secure connection with the external device based on the received audio signal.
Then, if the secure connection is carried out with the external device according to an embodiment, the processor 120 may transmit communication connection information to be communicatively connected with the external device and the external server (not shown) to the external device through the communication interface 110. The communication connection information may include at least one from among, for example, access point (AP) information or user account information, but is not limited thereto. The AP information may mean information on an AP device that performs a function of connecting an IOT device with a server, and SSID information corresponding to the AP and password information may be included in the AP information according to an example. Meanwhile, the user account information may mean ID and password information of a user account necessary for performing network connection through the server. The external device may be communicatively connected with the external server using the received communication connection information.

Then, the control method according to an embodiment may identify, based on the signal for secure connection being received from the external device (Y), the received signal strength indicator (RSSI) value of the received signal at operation S320. According to an example, the processor 120 may identify the RSSI value of the audio signal included with information on the PIN code for ownership authentication of the external device.
Then, the control method according to an embodiment may identify whether the speaker is included in the external device based on function information of the external device included in the received signal at operation S330. According to an example, the processor 120 may identify as the speaker being included in the external device based on function information of the external device included in the received wireless communication signal.
Then, if the speaker is identified as included in the external device according to an embodiment (Y), the control method may include transmitting the feedback information to the external device based on the identified RSSI value at operation S340. According to an example, the processor 120 may obtain, based on the identified RSSI value of the audio signal being identified as less than the minimum value from among the values corresponding to the pre-set range, feedback information for increasing the strength of the audio signal being transmitted from the external device. Then, if the speaker is identified as included in the external device, the processor 120 may transmit the obtained feedback information to the external device through the communication interface 110. In this case, the external device and the electronic device 100 may be in a state connected via device-to-device (D2D) communication, and the above will be described in detail through
Then, the control method according to an embodiment may identify whether an updated signal is received from the external device based on the feedback information at operation S350. According to an example, the processor 120 may identify whether an audio signal with the RSSI value being greater than or equal to the pre-set value is received from the external device that received the feedback information for increasing the strength of the audio signal which is being transmitted from the external device.
Then, the control method according to an embodiment may perform, based on an updated signal being received from the external device (Y), the secure connection with the external device based on the updated signal at operation S360. According to an example, the processor 120 may perform, based on the audio signal included with information for the secure connection with the external device being received as the signal having the RSSI value within the pre-set range, the secure connection with the external device based therefrom.
According to the above-described example, the electronic device 100 may be able to transmit feedback information for the external device by identifying whether the strength of the signal received from the external device is included within the pre-set range, and the external device may transmit an updated audio signal for successfully performing the secure connection based on the feedback information. Accordingly, the success rate of the communication connection between the electronic device 100 and the external device may be raised, and user satisfaction may be improved.

Then, the control method according to an embodiment may include performing, based on the speaker being identified as included in the external device (Y), connection via device-to-device (D2D) communication with the external device at operation S420. Here, the connection via D2D communication may mean technology with which communication connection is carried out between devices without having to pass through a separate communication connection device (or, infrastructure) such as a base station or a router (access point). According to an example, the processor 120 may be connected via D2D communication with the external device that transmitted the BLE advertising signal included with function information of the external device through the communication interface 110.
Then, the control method according to an embodiment may identify whether the identified RSSI value exceeded the pre-set range at operation S430. According to an example, the memory may be included with information associated with the pre-set range with respect to the RSSI values, and the processor 120 may identify the RSSI value of the audio signal included with information on the PIN code for ownership authentication of the external device, and identify whether the identified RSSI value exceeded the pre-set range based on information stored in the memory (not shown).
Alternatively, the wireless communication signal according to an example may include at least one from among information on a minimum value or a maximum value of the RSSI value for the secure connection, and the processor 120 may identify whether the identified RSSI value exceeds the pre-set range based on information on the minimum value or the maximum value of the RSSI value included in the received wireless communication signal.
Then, the control method according to an embodiment may include transmitting, based on the identified RSSI value exceeding the pre-set range (Y), feedback information associated with the pre-set range to the external device through a D2D communication channel at operation S440. The processor 120 according to an example may transmit, based on the identified RSSI value of the audio signal being identified as not included in the pre-set range according to the RSSI value being less than the minimum value from among the values corresponding to the pre-set range, feedback information for increasing the strength of the audio signal being transmitted from the external device to the external device through the D2D communication channel. Alternatively, the processor 120 according to an example may transmit, based on the identified RSSI value of the audio signal being identified as not included in the pre-set range according to the RSSI value exceeding the maximum value from among the values corresponding to the pre-set range, feedback information for reducing the strength of the audio signal being transmitted from the external device to the external device through the D2D communication channel.
Then, the control method according to an embodiment may include identifying whether the audio signal of the strength changed based on the feedback information is received from the external device at operation S450. According to an example, the processor 120 may receive the audio signal having the RSSI value within the pre-set range from the external device through the microphone (not shown) based on the feedback information for increasing the strength of the audio signal transmitted from the external device being transmitted to the external device.
Then, the control method according to an embodiment may include ending, based on the audio signal of the changed strength being received from the external device (Y), the connection via D2D communication and performing the secure connection at operation S460. According to an example, the processor 120 may end, based on the audio signal having the RSSI value within the pre-set range being received according to the feedback information for increasing the strength of the audio signal being transmitted from the external device being transmitted to the external device, the connection via D2D communication with the external device and perform the secure connection. Here, the connection via D2D communication may be a communication connection of a different type from the secure connection, and the connection via D2D communication according to an example may be a type of communication connection in which a signal that is being transmitted and received is not encrypted unlike a secure communication connection.

According to an embodiment, the processor 120 of an electronic device 500 may receive the audio signal for the secure connection from the external device 510 through the microphone (not shown), and receive the wireless communication signal including function information of the external device from the external device 510 through the communication interface 110.
The processor 120 according to an embodiment may transmit, based on the RSSI value of the received signal being identified as steadily reducing over time, feedback information for steadily increasing the RSSI value based on the pre-set range to the external device 510 through the communication interface 110.
According to an example, it may be assumed that a distance between the electronic device 500 and the external device 510 is steadily increased over time. The processor 120 may identify as the RSSI value of the audio signal received from the external device 510 being steadily decreased over time. For example, the processor 120 may identify the RSSI value of the signal received from the external device 510 at every pre-set period, and transmit, based on the RSSI value identified at every pre-set period being identified as steadily decreasing, feedback information for steadily increasing the RSSI value to be included in the pre-set range to the external device 510 through the communication interface 110.
Meanwhile, even if the RSSI value of the received signal is within the pre-set range according to an example, the processor 120 may transmit feedback information for controlling an output strength of the audio signal.
For example, the processor 120 may identify the RSSI value of the audio signal received from the external device 510 at every pre-set period. Based on the RSSI value of the received audio signal being identified as steadily decreasing within the pre-set range over time, feedback information for steadily increasing the RSSI value of the audio signal within the pre-set range may be transmitted to the external device 510 through the communication interface 110. That is, the processor 120 may transmit, based on the RSSI value of the received audio signal being identified as steadily decreasing over time even when the RSSI value of the received audio signal is within the pre-set range, feedback information for steadily increasing the output strength of the audio signal within the pre-set range to the external device 510 in order to raise the success rate of the communication connection between the electronic device 500 and the external device 510.
Alternatively, for example, the processor 120 may transmit, based on the RSSI value of the received audio signal being identified as steadily increasing within the pre-set range over time, feedback information for steadily reducing the RSSI value of the audio signal within the pre-set range to the external device 510 through the communication interface 110. That is, the processor 120 may transmit, based on the RSSI value of the received audio signal being identified as steadily increasing over time even when the RSSI value of the received audio signal is within the pre-set range, feedback information for steadily reducing the output strength of the audio signal within the pre-set range to the external device 510 to raise the success rate of the communication connection between the electronic device 500 and the external device 510. Meanwhile, the processor 120 according to an embodiment may identify an RSSI value for a secure connection based on information included in a signal received from the external device 510. According to an example, the wireless communication signal may include at least one from among information on the minimum value or the maximum value of the RSSI value for the secure connection. The processor 120 may identify feedback information based on at least one from among information on the minimum value or the maximum value of the RSSI value included in the received wireless communication signal.
According to an example, the processor 120 may transmit, based on the RSSI value identified based on at least one from among the minimum value or the maximum value being identified as exceeding the pre-set range, feedback information associated with the pre-set range to the external device 510 through connection via D2D communication. For example, the processor 120 may obtain, based on the identified RSSI value of the audio signal being less than the minimum value of the RSSI value included in the wireless communication signal, feedback information for increasing the strength of the audio signal being transmitted from the external device 510, and transmit the above to the external device 510 through the connection via D2D communication. Alternatively, for example, the processor 120 may obtain, based on the RSSI value of the audio signal being greater than the maximum value of the RSSI value included in the wireless communication signal based on information included in the received wireless communication signal, feedback information for reducing the strength of the audio signal being transmitted from the external device 510, and transmit the above to the external device 510 through the connection via D2D communication.

According to an embodiment, the processor 120 may identify, based on a wireless communication signal with function information of the external device 610 being first received from the external device 610 through the communication interface 110, an RSSI value of the received wireless communication signal.
According to an embodiment, the processor 120 may output, based on the microphone being identified as included in the external device 610 based on function information of the external device 610 included in the wireless communication signal, an audio signal for a secure connection with the external device 610 through the speaker (not shown) of the electronic device 600 based on the RSSI value of the identified wireless communication signal.
According to an example, the electronic device 600 may further include memory (not shown) stored with output size information (or, output strength information) of audio signals corresponding respectively to a plurality of RSSI values. The processor 120 may identify, based on an RSSI value of the wireless communication signal received from the external device 610 being identified as less than the pre-set value, an output size of the audio signal based on output size information of the audio signals corresponding respectively to the plurality of RSSI values stored in the memory (not shown), and control the speaker (not shown) to output an audio signal greater than or equal to the identified output size (or, output strength).
For example, it may be assumed that the RSSI value of the pre-set range is between 30 and 60. If the RSSI value of the wireless communication signal received from the external device is 20, the processor 120 may identify that an RSSI value of a signal received based on information on the pre-set range stored in the memory (not shown) exceeded the pre-set range based on the RSSI value being less than 30 which is the minimum value from among the values within the pre-set range. The processor 120 may identify an output size of an audio signal corresponding to 30 which is the minimum value from among the RSSI values included in the pre-set range based on the output size information of the audio signals corresponding respectively to the stored plurality of RSSI values, and control the speaker (not shown) to output an audio signal by greater than or equal to the identified output size of the audio signal.
Alternatively, for example, the processor 120 may identify whether the identified RSSI value of the wireless communication signal is less than the pre-set value based on information on at least one from among the minimum value (e.g., 30) or the maximum value (e.g., 60) of the RSSI value included in the received wireless communication signal. The processor 120 may identify that the RSSI value of the signal received based on information on at least one from among the minimum value or the maximum value of the RSSI value has exceeded the pre-set range according to the RSSI value being less than 30 which is the minimum value from among the values within the pre-set range. The processor 120 may identify an output size of the audio signal corresponding to 30 which is the minimum value based on the output size information of the audio signals corresponding respectively to the stored plurality of RSSI values, and control the speaker (not shown) to output the audio by greater than or equal to the identified output size of the audio signal.
However, the embodiment is not limited thereto, and the processor 120 for example may identify whether the identified RSSI value of the wireless communication signal exceeded the pre-set value based on at least one from among information on at least one from among the minimum value or the maximum value of the RSSI value included in the received wireless communication signal or information on the pre-set range associated with the RSSI values stored in the memory (not shown).

According to an example, it may be assumed that a distance between the electronic device 600 and the external device 610 steadily increases over time. The processor 120 may identify that the RSSI value of the audio signal received from the external device 610 steadily decreases over time. For example, the processor 120 may identify the RSSI value of the signal received from the external device 610 for each pre-set period. If the RSSI value identified for each pre-set period is identified as steadily decreasing, the speaker (not shown) of the electronic device 600 may be controlled for the output strength of the audio signal to be steadily increased. Alternatively, the processor 120 may output, through the speaker (not shown), the audio signals corresponding to the RSSI values included in the pre-set range based on the information stored in the memory (not shown).
Meanwhile, according to an embodiment, even if the RSSI value of the received signal is within the pre-set range, the processor 120 may control the output strength of the audio signal.
According to an example, it may be assumed that the RSSI value of the wireless communication signal being received is within the pre-set range. The processor 120 may control, based on the RSSI value of the received wireless communication signal being identified as steadily decreasing within the pre-set range over time, the speaker (not shown) of the electronic device 600 for the output strength of the audio signal to be steadily increased within the pre-set range based on the information stored in the memory (not shown). That is, the processor 120 may control, based on the RSSI value of the received wireless communication signal being identified as steadily decreasing over time even if the RSSI value of the received signal is within the pre-set range, the speaker (not shown) of the electronic device 600 for the output strength of the audio signal to be steadily increased in order to raise the success rate of the communication connection between the electronic device 600 and the external device 610.
