FIGS. 1 through 18, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged system or device.

FIG. 1 illustrates an IoT environment according to an embodiment.

Referring to FIG. 1, in an IoT environment 1000 according to an embodiment, a sound signal 10 corresponding to an utterance input of a user transferred from a first electronic device 100 (e.g., an AI speaker) to an IoT server 200 may allow a second electronic device 300 (e.g., another AI speaker) to control an IoT device 400 (e.g., a TV). In this case, the first electronic device 100 (or the second electronic device 300) may transmit/receive at least one of the sound signal 10 corresponding to the utterance input of the user, a control signal for the IoT device 400, and device identification information of the IoT device 400 through the IoT server 200 and a network 500.

According to an embodiment, the IoT environment 1000 may include the first electronic device 100, the IoT server 200, the second electronic device 300, the IoT device 400, and the network 500.

According to an embodiment, the first electronic device 100 may obtain an input corresponding to an utterance of the user as the sound signal 10. For example, the first electronic device 100 may obtain the sound signal 10 associated with a control command of the IoT device 400. In various embodiments, the first electronic device 100 may transmit the obtained sound signal 10 to the IoT server 200. In various embodiments, the first electronic device 100 may fail to emit a specified wavelength (e.g., an infrared wavelength).

According to an embodiment, the IoT server 200 may cause the second electronic device 300 to control the IoT device 400 based on a result of analyzing the sound signal 10 received from the first electronic device 100. For example, the IoT server 200 may derive identification information and the control command of the IoT device 400 from the sound signal 10. Also, the IoT server 200 may determine whether it is possible to control the IoT device 400 corresponding to the derived identification information by using the first electronic device 100. When it is impossible to control the IoT device 400 by using the first electronic device 100, the IoT server 200 may transmit a control signal corresponding to the control command to the second electronic device 300 associated with the IoT device 400. In various embodiments, the IoT server 200 may store the IoT device 400 information and the second electronic device 300 information in association with a specified place.

According to an embodiment, the second electronic device 300 may control the IoT device 400 depending on the control signal received from the IoT server 200. For example, when the second electronic device 300 receives the control signal from the IoT server 200, the second electronic device 300 may transmit the control signal by using a specified wavelength (e.g., an infrared wavelength). In this case, because the second electronic device 300 is linked to the IoT device 400 with regard to the specified place, the second electronic device 300 may emit the specific wavelength to the IoT device 400.

According to an embodiment, the IoT device 400 may perform an operation (e.g., power OFF) associated with the control signal under control of the second electronic device 300. In this case, the IoT device 400 may receive the control signal only through the specified wavelength (e.g., an infrared wavelength).

FIG. 2 illustrates components in an IoT environment according to an embodiment.

Referring to FIG. 2, each of a first electronic device 100_1, an IoT server 200_1, and the second electronic device 300 in an IoT environment 1000_1 may include components. Below, components included in the IoT environment 1000_1 will be described.

According to an embodiment, the first electronic device 100_1 may communicate with the IoT server 200_1, the second electronic device 300, and/or the IoT device 400 over the network 500 (e.g., an LAN, a WAN, an Internet, an Ad-hoc network, or a telephone network). For example, the first electronic device 100_1 may obtain a sound signal (e.g., the sound signal 10 of FIG. 1) corresponding to an utterance input of the user and may transmit the sound signal to the IoT server 200_1 by connecting to the network 500 through wired or wireless communication. The first electronic device 100_1 may include a microphone 110, a first communication circuit 120, a first memory 130, a first processor 140, and/or a speaker 150.

According to an embodiment, the microphone 110 may receive a sound signal (e.g., an input corresponding to an utterance of a user). For example, the microphone 110 may operate in a state of being always driven (e.g., an always on state) for the purpose of receiving a sound signal. For another example, the microphone 110 may be activated according to a user input on a button disposed at a portion of the first electronic device 100_1 and may then operate.

In various embodiments, at least a portion of the microphone 110 may be exposed to the outside of the first electronic device 100_1 for the purpose of efficiently receiving a sound signal. For another example, the microphone 110 may be positioned within a housing of the first electronic device 100_1.

According to an embodiment, the first communication circuit 120 may support a communication function of the first electronic device 100_1 such that the first electronic device 100_1 communicates with the IoT server 200_1, the second electronic device 300, and/or the IoT device 400. For example, the first communication circuit 120 may transmit/receive at least one of data, a signal, and information about an operation of the IoT environment 1000_1 by connecting to the network 500, which is constructed between the IoT server 200_1, the second electronic device 300, and/or the IoT device 400, through wired and/or wireless communication complying with a defined protocol.

According to an embodiment, the first memory 130 may store query data to be output through the speaker 150. For example, the first memory 130 may store at least one of at least one syllable associated with the query data, a word in which the at least one syllable is included, or a sentence in which the word is included. In this case, the query data may be output through the speaker 150 as a sound associated with a sound signal (e.g., an input corresponding to an utterance of a user). For another example, the first memory 130 may store at least one command associated with a function operation control of components of the first electronic device 100_1. For another example, the first memory 130 may store at least one data associated with an operation of the first electronic device 100_1. For example, the first memory 130 may store at least one of identification information (e.g., model information, version information, operator information, and/or operating system information) of the first electronic device 100_1 and information about a location of the first electronic device 100_1 disposed in the IoT environment 1000_1.

According to an embodiment, the first processor 140 may control components of the first electronic device 100_1. For example, the first processor 140 may be electrically or operatively connected with components of the first electronic device 100_1, and the first processor 140 may transfer at least one command associated with a function operation to the components or may perform various kinds of operations, data processing, or the like.

According to an embodiment, the first processor 140 may obtain a sound signal (e.g., the sound signal 10 of FIG. 1) through the microphone 110. Also, the first processor 140 may transmit the sound signal to the IoT server 200_1 through the first communication circuit 120.

According to an embodiment, the first processor 140 may allow specified sound data to be output through the speaker 150. For example, the first processor 140 may allow a sound-type query, which the user is able to hear, to be output through the speaker 150.

In various embodiments, the first processor 140 may be at least one of a central processing unit, an application processor, and a communication processor.

According to an embodiment, the speaker 150 may output specified sound data. For example, in the case where an operating state of the IoT device 400 is changed according to a control operation of the IoT server 200_1 associated with the sound signal, the speaker 150 may output a sound-type query stored in the first memory 130.

In various embodiments, the speaker 150 may be implemented with at least one speaker. Also, at least a portion of the speaker 150 may be exposed to the outside of the first electronic device 100_1 for the purpose of efficiently outputting the sound data. For another example, the speaker 150 may be positioned within the housing of the first electronic device 100_1.

In various embodiments, the first electronic device 100_1 may be a hub device or an artificial intelligence (AI) device that acts as a repeater between the IoT server 200_1, the second electronic device 300, and the IoT device 400. In this regard, at least one first electronic device 100_1 may be disposed at least a portion of at least one space physically or logically defined within a specific region where the IoT environment 1000_1 is formed.

In various embodiments, the first electronic device 100_1 may not include at least one of the above components or may further include any other component(s). For example, the at least one first electronic device 100_1 may further include a battery supplying a power to the above components or a display outputting various kinds of content.

In various embodiments, the first electronic device 100_1 may be connected with the IoT server 200_1 through an access point (e.g., a Wi-Fi router).

According to an embodiment, the IoT server 200_1 may integrally manage the first electronic device 100_1, the second electronic device 300, and the IoT device 400 that are registered at the IoT environment 1000_1 or the IoT server 200_1. For example, depending on the sound signal (e.g., the sound signal 10 of FIG. 1) received from the first electronic device 100_1, the IoT server 200_1 may allow one associated with the IoT device 400 from among the first electronic device 100_1 or the second electronic device 300 to control the IoT device 400. Also, the IoT server 200_1 may analyze the sound signal received from the first electronic device 100_1 and may process an input corresponding to an utterance of the user. The IoT server 200_1 may include a second communication circuit 210, a second memory 220, and a second processor 230.

According to an embodiment, the second communication circuit 210 may support a communication function of the IoT server 200_1 such that the IoT server 200_1 communicates with the first electronic device 100_1, the second electronic device 300, and the IoT device 400. For example, the second communication circuit 210 may transmit/receive at least one of the data, the signal, and the information about the operation of the IoT environment 1000_1 by connecting to the network 500, which is constructed between the first electronic device 100_1, the second electronic device 300, and the IoT device 400, through wired and/or wireless communication complying with a defined protocol.

According to an embodiment, the second memory 220 may store the IoT device 400 and the second electronic device 300 (or the first electronic device 100_1) in association with a specified place. The second memory 220 may include a database 221 in which various kinds of information of the second memory 220 are organized.

In various embodiments, the IoT device 400 information and the second electronic device 300 information (or the first electronic device 100_1 information) mutually linked with regard to a specified place may be stored in the database 221. For example, a table (or a mapping table) associated with mapping between the IoT device 400 and the second electronic device 300 (or the first electronic device 100_1) may be stored in the database 221. For example, the mapping table may be identical or similar to Table 1 below.

TABLE 1
			Electronic device capable of
ID	Place	IoT device	controlling IoT device
1	Living	Identification	Identification information of
	room	information of TV	second electronic device

Referring to Table 1 above, a TV information disposed at a specified place being a living room may be stored in the database 221 according to an embodiment in association with a second electronic device. For example, the TV may be mapped on the second electronic device located at a place capable of controlling the TV, and the mapped result may be stored in the database 221. In this case, a second electronic device being any other electronic device associated with the TV may be disposed at the living room being the same place as the TV. That is, the second electronic device 300 information (or the first electronic device 100_1 information) that is capable of transmitting a control signal to the IoT device 400 by using a specified wavelength may be stored in the database 221 in a state of being linked to the IoT device 400 with regard to the specified place.

According to an embodiment, the second processor 230 may control components of the IoT server 200_1. For example, the second processor 230 may be electrically or operatively connected with components of the IoT server 200_1, and the second processor 230 may transfer at least one command associated with a function operation to the components or may perform various kinds of operations, data processing, or the like.

According to an embodiment, the second processor 230 may receive a sound signal (e.g., the sound signal 10 of FIG. 1) transmitted from the first electronic device 100_1 through the second communication circuit 210. Also, the second processor 230 may derive the identification information and the control command of the IoT device 400 from the sound signal. For example, the second processor 230 may transmit a control signal corresponding to the control command to the second electronic device 300 (or the first electronic device 100_1) capable of transferring the control command to the IoT device 400 corresponding to the derived identification information.

According to an embodiment, the second processor 230 may analyze and process a sound signal (e.g., the sound signal 10 of FIG. 1) transmitted from the first electronic device 100_1 through the second communication circuit 210. The sound signal may involve, for example, a command or an intention associated with an operation of the IoT device 400 present at (or present at a place adjacent to) the same place as the second electronic device 300 (or the first electronic device 100_1). With regard to analyzing and processing the sound signal, the second processor 230 may include an automatic speech recognition (ASR) module 231 and a natural language understanding (NLU) module 232. In various embodiments, the ASR module 231 and the NLU module 232 may be independent of each other or may be at least partially integrated.

According to an embodiment, the ASR module 231 may recognize a sound signal (e.g., the sound signal 10 of FIG. 1) received from the first electronic device 100_1 and may convert the sound signal into text data. For example, the ASR module 231 may convert the sound signal into text data by using an acoustic model including at least one information about an utterance or a language model including combination information of phonemes.

According to an embodiment, the NLU module 232 may derive an intention of a user utterance input associated with the sound signal (e.g., the sound signal 10 of FIG. 1) based on the text data transferred from the ASR module 231. For example, the NLU module 232 may derive the intention of the user utterance input associated with the sound signal by dividing the text data in a grammatical unit (e.g., a word, a phrase, or a morpheme), analyzing a grammatical element or a linguistic characteristic for each unit, and determining a meaning of the text data. Also, the NLU module 232 may derive the identification information of the IoT device 400 based on the text data transferred from the ASR module 231.

According to an embodiment, the second processor 230 may select the second electronic device 300 (or the first electronic device 100_1) capable of controlling the IoT device 400. With regard to the selection, the second processor 230 may include a selector module 233.

According to an embodiment, the selector module 233 may be provided with information about the second electronic device 300 (or the first electronic device 100_1), which is capable of controlling the IoT device 400 corresponding to the identification information derived from the NLU module 232, from the second memory 220. For example, in the case where one second electronic device 300 (or one first electronic device 100_1) information is provided from the second memory 220, the selector module 233 may select the second electronic device 300 (or the first electronic device 100_1) thus provided, as a control device for the IoT device 400. For another example, in the case where a plurality of second electronic devices 300 (or a plurality of first electronic device 100_1) are provided from the second memory 220, the selector module 233 may select one second electronic device 300 (or one first electronic device 100_1) based on at least one of network performance information and location information about the IoT device 400. In various embodiments, the location information may be information for selecting the second electronic device 300, which is located within a shorter distance, from among the plurality of second electronic devices 300 associated with the IoT device 400. In various embodiments, the network performance information may be information for selecting the second electronic device 300, which is connectable to the network 500 or has a high communication efficiency for the network 500, from among the plurality of second electronic devices 300 associated with the IoT device 400.

In various embodiments, the second processor 230 may be at least one of a central processing unit, an application processor, and a communication processor.

According to an embodiment, the second electronic device 300 may control the IoT device 400 depending on the control signal received from the IoT server 200_1. For example, the second electronic device 300 may transmit the control signal by using a specified wavelength (e.g., an infrared wavelength) in a direction in which the IoT device 400 is disposed. The second electronic device 300 may include a sensor unit 310 capable of emitting the specified wavelength.

According to an embodiment, the sensor unit 310 may transmit a signal of a specified wavelength (e.g., an infrared wavelength) toward the IoT device 400. In this case, the control signal may be included in the signal of the specified wavelength transmitted from the sensor unit 310. In various embodiments, the sensor unit 310 may be an infrared sensor. Also, at least a portion of the sensor unit 310 may be exposed to the outside such that the emission of the specified wavelength toward the IoT device 400 is possible, and the exposed portion may be disposed to face the IoT device 400. For example, the signal of the specified wavelength may be defined by a frequency, a length, and/or a pattern.

In various embodiments, the second electronic device 300 may include components that are identical or similar to those of the first electronic device 100_1. For example, in the case where the second electronic device 300 including components identical or similar to those of the first electronic device 100_1 obtains a sound signal (e.g., the sound signal 10 of FIG. 1) from the user, the second electronic device 300 may transmit the sound signal to the IoT server 200_1 such that a control for the IoT device 400 is possible.

In various embodiments, the second electronic device 300 may be connected with the IoT server 200_1 through an access point (e.g., a Wi-Fi router).

According to an embodiment, the IoT device 400 may operate under control of the second electronic device 300 (or the first electronic device 100_1). For example, when the control signal of the specified wavelength is transmitted from the second electronic device 300, the IoT device 400 may operate (e.g., may be powered off) according to the control signal. In this case, the IoT device 400 may be linked to the second electronic device 300 with regard to a specified place.

In various embodiments, the IoT device 400 may transmit various kinds of operating information (e.g., state information, function information, and the like) to the first electronic device 100_1, the IoT server 200_1, the second electronic device 300, or a mobile communication terminal of the user in the form of a batch or a stream.

In various embodiments, the IoT device 400 may be an IoT technology-based service target (e.g., an electronic product).

The description is given in FIG. 2 as the IoT device 400 is an IoT technology-based electronic product, but embodiments of the disclosure are not limited thereto. In the specification, the term “IoT device” may mean any electronic device capable of being registered at an IoT server. For example, the IoT device 400 may be a legacy electronic device that does not include an Internet access function. In this case, the legacy electronic device may operate based on the signal of the specified wavelength from the second electronic device 300. In the case where the IoT device 400 is an electronic device capable of supporting an Internet access, the IoT device 400 may operate based on a signal from the IoT server 200_1.

An example is illustrated in FIG. 2 as the IoT server 200_1 is one server, but embodiments of the disclosure are not limited thereto. For example, the IoT server 200_1 may be implemented with a plurality of servers (e.g., a first IoT server 1120 and a sound signal processing server 1170 of FIG. 11). In an embodiment, the database 221 of the IoT server 200_1 and the components 231, 232, and 233 for recognizing a sound command may be implemented with separate servers.

FIG. 3 illustrates components in an IoT environment according to an embodiment.

FIG. 11 illustrates a device registration and control system 1100 according to various embodiments.

Referring to FIG. 11, the device registration and control system 1100 may include a first electronic device 1110, the first IoT server 1120, a second electronic device 1130, an external electronic device 1140, a DB server 1150, an antenna server 1160, and/or the sound signal processing server 1170.

According to an embodiment, the first electronic device 1110 (e.g., the first electronic device 100 of FIGS. 1 to 9 or the electronic device 901 of FIG. 10) may be a device that stores identification information of various external electronic devices 1140 (e.g., first identification information including information about an external electronic device) and controls the external electronic device 1140 (e.g., the IoT device 400 of FIGS. 1 to 9) by using the second electronic device 1130 (e.g., the second electronic device 300 of FIGS. 1 to 9). The first electronic device 1110 may allow the first IoT server 1120 to transmit a signal for controlling the external electronic device 1140 to the second electronic device 1130. For example, the first electronic device 1110 may identify an operation (e.g., a power ON/OFF, a channel change, and/or a volume control) of the external electronic device 1140. For example, the first electronic device 1110 may identify an operation for a control of the external electronic device 1140 by using an external electronic device managing app.

According to an embodiment, the first electronic device 1110 may identify an operation that is supported by the external electronic device 1140 in the process of registering the external electronic device 1140 at the external electronic device managing app. For example, the first electronic device 1110 may obtain information (e.g., a model name, a type, and/or a manufacturer of the external electronic device 1140) of the external electronic device 1140 in the process of registering the external electronic device 1140 at the external electronic device managing app of the first electronic device 1110 and/or the first IoT server 1120. The first electronic device 1110 may obtain information of the external electronic device 1140 based on a user input. For example, the first electronic device 1110 may transfer the information of the external electronic device 1140 to the second electronic device 1130 through the first IoT server 1120, and the second electronic device 1130 may obtain information about an operation, which is supported by the external electronic device 1140 and corresponds to the information of the external electronic device 1140, from the DB server 1150. The second electronic device 1130 may transfer information for a control of the external electronic device 1140 (e.g., information of an operation supported by the external electronic device 1140 and/or information about a signal of a specified wavelength necessary for a control of the external electronic device 1140) through the first IoT server 1120. For another example, the first electronic device 1110 may obtain information for a control of the external electronic device 1140 (e.g., information of an operation supported by the external electronic device 1140 and/or information about a signal of a specified wavelength necessary for a control of the external electronic device 1140) through the first IoT server 1120 or directly from the DB server 1150. For example, the DB server 1150 may include a database for a plurality of electronic devices. The database of the DB server 1150 may include information (e.g., a model name, a manufacturer, and/or an identification number) about an electronic device and information about an operation (e.g., information of a supported operation and information about a signal of a specified wavelength necessary to perform the supported operation) supported by the electronic device.

According to an embodiment, the first electronic device 1110 may further obtain additional information about the external electronic device 1140 in the process of registering the external electronic device 1140 (e.g., a TV or a set-top box) of a specific type. For example, the first electronic device 1110 may obtain information (e.g., content provider information) about the external electronic device 1140 through the antenna server 1160. The first electronic device 1110 may obtain content provider information (e.g., a name of a content provider) providing content to the external electronic device 1140 from the antenna server 1160 based on at least one of a user input, location information of the first electronic device 1110, or location information of the second electronic device 1130. The additional information of the external electronic device 1140 may be stored in the first IoT server 1120 in association with the external electronic device 1140.

According to an embodiment, the first IoT server 1120 may include a memory, a communication circuit, a processor, or the like therein. For example, the first IoT server 1120 may share and transfer information about the external electronic device 1140, IoT environment information, and the like between the first electronic device 1110 and the second electronic device 1130. The first IoT server 1120 may store information about the first electronic device 1110 and the external electronic device 1140, which is registered at the external electronic device managing app operating at the first electronic device 1110, and information of an external electronic device not added, independently of each other.

According to an embodiment, the sound signal processing server 1170 may be configured to receive a sound command signal and information about the sound command signal from the first electronic device 1110 and/or the second electronic device 1130 and to process the received sound command signal and information. For example, the sound signal processing server 1170 may perform operations corresponding to the ASR module 231, the NLU module 232, and the selector module 233 described with reference to FIG. 2. An example is illustrated in FIG. 11 as the sound signal processing server 1170 and the first IoT server 1120 are independent of each other, but embodiments of the disclosure are not limited thereto. For example, the sound signal processing server 1170 and the first IoT server 1120 may be implemented with one server (e.g., the IoT server 200 of FIG. 7). For example, the first electronic device 1110 may receive a sound command from the user and may transmit a sound signal or information corresponding to the sound command to the sound signal processing server 1170. The sound signal processing server 1170 may process the received sound signal or the received information and may transfer the processed result to the first IoT server 1120. For example, the sound signal or the information may include a command for a control of any other electronic device (e.g., the external electronic device 1140). In this case, the first IoT server 1120 may identify the external electronic device 1140 targeted for a control and a control operation based on the information received from the sound signal processing server 1170 and may transmit information, which causes the second electronic device 1130 to perform the control operation, to the second electronic device 1130. The second electronic device 1130 may allow the external electronic device 1140 to perform the above control operation by radiating a control signal (e.g., a signal of a specified frequency) corresponding to the received information.

As in the above description, the IoT server 1120 may receive a command for a control based on an input that corresponds to an utterance of the user received from the first electronic device 1110 and/or the second electronic device 1130 and is processed by the sound signal processing server 1170. After the first IoT server 1120 receives the command for the control, the first IoT server 1120 may control an operation of the external electronic device 1140 based on information about the external electronic device 1140. For example, a command for a control of the external electronic device 1140 may include content identification information (e.g., a content provider name, a channel, and/or a content name). In this case, the first IoT server 1120 may identify an operation corresponding to the control command through the antenna server 1160 based on the content provider information about the external electronic device 1140. For example, the first IoT server 1120 may obtain content information (e.g., video on demand information and/or organizational table information) corresponding to the content provider information about the external electronic device 1140 from the antenna server 1160 or an Internet and may identify a control operation of the external electronic device 1140 by using the content identification information corresponding to the control command. For example, in the case where a sound command includes a name of a specific program, the first IoT server 1120 may identify channel and/or time information about broadcasting of a specific program based on information (e.g., first identification information including information about an external electronic device) of the external electronic device 1140. The first IoT server 1120 may allow the second electronic device 1130 to radiate a control signal such that the external electronic device 1140 is capable of receiving the corresponding program based on the identified channel and/or time information.

According to an embodiment, the second electronic device 1130 (e.g., an AI speaker) may receive, from the first IoT server 1120, the control signal and/or the control instruction transmitted from the first electronic device 1110 to the first IoT server 1120. In various embodiments, the second electronic device 1130 may control the external electronic device 1140 by using a specified wavelength (e.g., an infrared wavelength) associated with the control signal and/or the control instruction thus received. For example, the second electronic device 1130 may obtain an input corresponding to an utterance of the user as a sound signal and may transmit the obtained sound signal to the sound signal processing server 1170. The sound signal processing server 1170 may derive identification information and a control instruction of a device from the received sound signal and may transmit the derived result to the first IoT server 1120. The second electronic device 1130 may obtain information (e.g., manufacturer information, model information, instruction information, a control signal, and/or a control instruction (e.g., a device type, a code-set name, code-key information, or information of a specified wavelength) of the external electronic device 1140 through the DB server 1150. The second electronic device 1130 may identify the external electronic device 1140 targeted for a control, based on the obtained information.

According to an embodiment, the external electronic device 1140 (e.g., a TV, a set-top box, an electric fan, an air conditioner, an air cleaner, a robot cleaner, a lighting device, or the like) may perform an operation (e.g., power ON/OFF, a channel change, and/or a volume control) corresponding to a control signal that the second electronic device 1130 transmits. The external electronic device 1140 may receive the control signal, which is based on a specified wavelength (e.g., an infrared wavelength), from the second electronic device 1130.

According to an embodiment, the DB server 1150 may include a memory, a communication circuit, a processor, or the like therein. The DB server 1150 may store information (e.g., manufacturer information, model information, instruction information, a control signal and/or a control instruction (e.g., a device type, a code-set name, code-key information), or information of a specified wavelength) of the external electronic device 1140 in a memory. For example, when the DB server 1150 receives a signal requesting information of the external electronic device 1140 from the second electronic device 1130, the DB server 1150 may transmit DB information including the information to the second electronic device 1130. The second electronic device 1130 may store the received DB information in a memory.

According to an embodiment, the antenna server 1160 may include a memory, a communication circuit, a processor, or the like therein. The antenna server 1160 may store information (e.g., TV service provider information) about the external electronic device 1140 in the memory. For example, in the case where the external electronic device 1140 that the first electronic device 1110 intends to add to the external electronic device managing app is a TV or a set-top box, the antenna server 1160 may directly transmit, to the first electronic device 1110, information necessary in the process (e.g., location setting or TV service provider setting) where the first electronic device 1110 adds the external electronic device 1140 through the external electronic device managing app. For example, the antenna server 1160 may transmit information including information about the external electronic device 1140 to the first electronic device 1110 through the first IoT server 1120. For example, the antenna server 1160 may transmit information (e.g., channel information, content information, or genre information) about an input corresponding to an utterance of the user to the first IoT server 1120.

FIG. 12 illustrates a flowchart 1200 of a device registration method using an external electronic device managing app of an electronic device according to various embodiments.

Referring to FIG. 12, according to an embodiment, in operation 1205, an electronic device (e.g., the first electronic device 1110 of FIG. 11) may sense a selection input for selecting a second electronic device (e.g., the second electronic device 1130 of FIG. 11) through a display. For example, the selection input for selecting the second electronic device may be a touch input of the user sensed through a user interface output in the display. The user interface may include information (e.g., an external electronic device list and a guide phrase for registration of an external electronic device) for controlling an external electronic device.

According to an embodiment, in operation 1210, the electronic device may receive, from a first IoT server (e.g., the first IoT server 1120 of FIG. 11), information indicating that the second electronic device is registering the external electronic device by the second user.

According to an embodiment, when the electronic device receive the information indicating that the second electronic device is registering the external electronic device (e.g., Yes in operation 1210), the electronic device may perform operation 1215.

In operation 1215, the electronic device may display notification information including an end message of the user interface in the display. The notification information may further include information indicating that an external user is using the user interface.

According to an embodiment, when the electronic device does not receive the information indicating that the second electronic device is registering the external electronic device (e.g., No in operation 1210), the electronic device may perform operation 1220.

In operation 1220, the electronic device may transmit, to the IoT server, a signal including the information indicating that the second electronic device is registering the external electronic device and may display information about the external electronic device in the display. The information about the external electronic device may further include a kind of an external electronic device (e.g., a TV, a set-top box, an electric fan, an air fryer, or a lighting device) that the user intends to add and brand information of the external electronic device.

According to an embodiment, in operation 1225, the electronic device may sense an input of selecting at least one of external electronic devices displayed in the display. For example, the input of selecting at least one of the external electronic devices may be a touch input of the user.

According to an embodiment, in operation 1230, the electronic device may transmit a signal including information about the external electronic device selected by the input to the IoT server. The IoT server may transmit the information about the external electronic device to the second electronic device (e.g., the second electronic device 1130 of FIG. 11). The IoT server may store the information about the selected external electronic device and information about an unselected external electronic device based on the received signal, independently of each other.

FIG. 13 illustrates a user interface screen that is output when a second user is using a registration step user interface of an external electronic device, according to various embodiments.

Referring to FIG. 13, according to an embodiment, in screen 1301, an electronic device (e.g., the first electronic device 1110 of FIG. 11) may output a user interface for registration of an external electronic device (e.g., the external electronic device 1140 of FIG. 11) in a display. For example, a user interface 1305 in which a previous button for returning to a previous screen, a sentence indicating a summary of contents of a current screen, and a button for providing a control function of any other external electronic device managing app are included may be provided at the top of screen 1301. For example, a guide message necessary to add the external electronic device to a second electronic device (e.g., the second electronic device 1130 of FIG. 11) may be included in screen 1301. For example, a button 1315 for switching into a screen showing a list of external electronic devices to be registered (or to be added) may be included in screen 1301. In the case where the second user is using the user interface, when a user input 1320 on the button 1315 is sensed, screen 1302 may be output in the display.

According to an embodiment, in screen 1302, a message 1325 in which information indicating that the second user is registering the external electronic device at the second electronic device is included may be output in the display. The message may further include notification information including an end message of the user interface.

FIG. 14 illustrates a user interface screen that is output when an external user is using a registration step user interface of an external electronic device managing app, according to various embodiments;

Referring to FIG. 14, according to an embodiment, in screen 1401, an electronic device (e.g., the first electronic device 1110 of FIG. 11) may output a user interface for registration of an external electronic device (e.g., the external electronic device 1140 of FIG. 11) in a display. For example, a button 1406 for switching into a screen showing a list of external electronic devices to be registered may be included in screen 1401. In the case where the external user is using the user interface, when a user input 1405 on the button 1406 is sensed, the display may output screen 1402.

According to an embodiment, in screen 1402, the electronic device may output a message 1410 in which contents guiding the notice in the process of controlling the external electronic device is included. The electronic device may output a screen in which a device kind list 1415 of external electronic devices targeted for a control is included. For example, device kinds (e.g., a TV, a set-top box, an electric fan, an air fryer, and a lighting device) of external electronic devices that are registered at the electronic device and are capable being controlled through an external electronic device managing app may be included in the list 1415. An add button 1420 for further showing any other kind(s) except for the device kinds of external electronic devices output in the list 1415 may be further included in the screen 1402. For example, in the case where a user input on at least one of the device kinds of external electronic devices in the list 1415 is sensed, the display may output screen 1403.

According to an embodiment, in screen 1403, the electronic device may output a screen in which a brand list 1425 (e.g., SAMSUNG, LG, SONY, VIZIO, and PANASONIC) associated with the selected external electronic device is included. For example, in the case where a user input (e.g., a touch input) on at least one of brand kinds of the list 1425 is sensed, the display may output screen 1404.

According to an embodiment, in screen 1404, the electronic device may output a user interface of testing whether the selected external electronic device operates normally, based on the user inputs sensed in screen 1402 and screen 1403. For example, a message 1430 in which names of an external electronic device selected by an input of the user and a separate electronic device (e.g., the second electronic device 1130 of FIG. 11) (e.g., an AI speaker) receiving a control signal of the electronic device are included may be output in the user interface. For example, an illustration 1435 corresponding to an external electronic device targeted for a control may be output in the user interface. For example, a button 1440 corresponding to the case where the external electronic device is not correctly controlled by the separate electronic device receiving the control signal of the electronic device and/or a button 1445 corresponding to the case where the external electronic device is correctly controlled by the separate electronic device may be included in the user interface. For example, when a user input on the button 1440 corresponding to the case where the external electronic device is not correctly controlled is sensed, the electronic device may again determine whether the external electronic device operates, by using a user interface of testing any other function except for the user interface. For example, when a user input on the button 1445 corresponding to the case where the external electronic device is correctly controlled is sensed, the electronic device may complete the test associated with whether to operate and may close the user interface.

For example, the second electronic device 1503 may store the received pieces of information in a memory.

In operation 1585, the second electronic device 1503 may generate a control signal, which is based on a specified wavelength (e.g., an infrared wavelength), by using the converted information received from the first IoT server 1502. The second electronic device 1503 may transmit the control signal to the external electronic device 1506. For example, the second electronic device 1503 may allow the external electronic device 1506 to perform the above control operation by radiating a control signal (e.g., a signal of a specified frequency) corresponding to the received information.

FIG. 16 illustrates an additional user interface when an external electronic device to be registered at an electronic device is a TV or a set-top box, according to various embodiments.

According to various embodiments, in screen 1601, a user interface may include a location tap 1605, and/or a TV service provider tap 1610.

The service provider list 1620 may be updated based on a usage history of the user or may be synchronized based on the location information of the electronic device. For example, when a user input of selecting the external electronic device, the location information, and/or the service provider is sensed, the electronic device may transmit a signal including information about the selected contents to the antenna server 1160. The antenna server 1160 may transmit identification information (e.g., a headendID) determined based on the received signal to the electronic device. The electronic device may receive the information and may store the received information in a memory. The electronic device may transmit separate identification information (e.g., a headendID) to the first IoT server 1502 based on the received identification information such that the separate identification information is mapped onto the identification information (e.g., the first identification information) of the external electronic device 1506, the identification information (e.g., the second identification information) of the second electronic device 1503 associated with the external electronic device 1506, the content provider information, and control information of the external electronic device 1506 and the mapping result is stored in a database.

For example, the information may include a control signal commanding the second electronic device to control the external electronic device.

According to an embodiment, in operation 1730, the second electronic device may control a registered external electronic device, based on the control signal received from the first IoT server. For example, the second electronic device may transmit the control signal to the external electronic device by using a specified wavelength (e.g., an infrared wavelength), depending on the signal received from the first IoT server. According to various embodiments, under control of the second electronic device, the external electronic device may perform the following operation associated with the control signal: changing a channel, broadcasting a program in which content genre information determined based on an utterance input of the user is included. In this case, the external electronic device may receive the control signal only through the specified wavelength (e.g., an infrared wavelength).

According to an embodiment, in screen 1802, a screen 1830 in which a plurality of buttons for controlling the external electronic device are included may be output at the top of the user interface. For example, the plurality of buttons may include buttons for power ON/OFF, a volume control, channel change, mute, backward, home screen output, and the like. A keypad screen 1840 may be output at the bottom of the user interface. For example, the keypad screen 1840 may include a plurality of buttons supporting a number input, a character input, a figure input, and the like. For example, when a user input on a part of the buttons of the user interface is sensed, the first electronic device may transmit a control signal (e.g., capability information or identification information (e.g., the first identification information) of an external electronic device) enabling an execution of a function (e.g., a power ON/OFF, a volume control, channel change, mute, backward, or home screen output function) corresponding to the button to a first IoT server (e.g., the first IoT server 1120 of FIG. 11). The first IoT server may convert the received control signal into information about a device type, a code-set name, a code-key, or the like, may verify identification information (e.g., the second identification information) of a second electronic device (e.g., the second electronic device 1130 of FIG. 11) based on the converted information and the identification information (e.g., the first identification information) of the external electronic device, and may transmit information about the converted device type, code-set name, or code-key to the second electronic device. The second electronic device may control the external electronic device through a specified wavelength (e.g., an infrared wavelength), based on the control signal received from the first IoT server.

The configuration of the user interface illustrated in screen 1802 exemplifies the case of selecting a TV of registered devices in screen 1801, and embodiments of the disclosure are not limited thereto.
