4) Device Thing 200 notifies system 100 that the incoming call is unanswered or busy.

5) In the case of a voice / video call, the system 100 enables voice / video recording by playing a voice announcement on the calling party. If it is a text, it informs the receiving party of the text so that the receiver can check the received text later.

6) The calling party records and records the voice / video message to the recipient according to the announcement.

7) After the recording is completed, the system 100 notifies the receiving side that there is an incoming voice / video message.

8) The receiving side device thing 200 indicates that a message has been received, for example, by using an LED and the like, and the user who recognizes the message requests to listen to the received message by manipulating a voice command or the device thing 200.

9) The receiving device 200 receives a request for receiving a stored voice / video / text message from the system 100 and plays the same through the device 200.

FIG. 22 illustrates an example of a screen when an application is used by an OTT operator or a communication operator, and illustrates an example of a user interface for a call from a user terminal (smartphone) to the device thing 200.

Referring to the left side of FIG. 22, it can be seen that the ID of the device thing 200 is displayed, and when it is selected, it can be seen that the screen is changed to a screen of a call request and a call state as shown on the right side.

FIG. 23 is a diagram illustrating a case where the present invention is applied to an existing messaging application, and is a case where the present invention is applied to a widely used KakaoTalk application.

Referring to the left side of FIG. 23, it can be seen that the ID of the device thing 200 is registered in a contact (friend list) of a messaging application.

In this state, when the user touches the ID of the device thing 200, information about the device thing 200 is displayed, and when a call button is pressed, a voice call is sent to the device thing 200 and a call is made. You can check it.

24 illustrates a case where the present invention is applied to a call application provided by a telecommunication company (eg, T-phone of SK Telecom).

As shown in FIG. 24, when the ID of the device thing 200 is registered in the contact of the call application and selected, the call screen is changed to the call origination screen or the call screen.

In the above, the present invention has been described with reference to the preferred embodiment of the present invention, it should be noted that the present invention is not limited to the above embodiment.

For example, the device thing 200 may include various other devices in addition to the IoT device and the AI device.
