Description

Service system supporting voice call using digital assistant device, method thereof and non-transitory computer readable medium having computer program recorded thereon }

The present invention relates to a service system for supporting voice calls using a digital assistant, a method thereof, and a non-volatile recording medium on which a computer program is recorded. In particular, the present invention relates to a call between a digital assistant and a calling terminal through a caller's voice command. , It relates to a service system, method, and non-volatile recording medium on which a computer program is recorded that utilizes the called terminal when connecting a call between a digital assistant and a calling terminal, but prevents the actual call from going through the called terminal.

In a situation where home automation using digital assistant devices such as AI (Artificial Intelligence) speakers is becoming common, and digital assistant devices are becoming widespread like new home appliances called AI speakers, you can make voice calls with the desired person using digital assistant devices. The need to perform is increasing.

In the case of voice calls using an existing digital assistant device, there is a known method in which the digital assistant device has a phone function, and when you subscribe to a voice call service, you use the digital assistant device as an actual phone to make a voice call.

However, in order to do this, there is a problem of not only having to configure the phone function in the digital assistant device, but also having to subscribe to a voice call service that continuously incurs high costs and is inconvenient to subscribe to.

In addition, for businesses that manufacture or provide services for digital assistant devices, there is the problem of having to be certified as a device for voice calls or as a telecommunications business operator for providing services.

As another method, a method of utilizing a voice call terminal owned by a user is also known, in which a digital assistant device and a voice call terminal are connected through wired/wireless communication to interface only with voice input and output.

In other words, after a digital assistant device equipped with a speaker and microphone is connected to a voice call terminal using a known short-distance communication method for voice calls such as Bluetooth, when the call between the actual voice call terminal and the other party's terminal is connected, the microphone and speaker of the voice call terminal are connected. Instead, the microphone and speaker of the digital assistant device take over, and there is a limitation that the voice call terminal and the digital assistant device must be close together, and since the voice call terminal is the subject of tasks such as making or ending a call, it is inconvenient to operate the terminal. However, there are limitations that the service server cannot manage to provide digital assistant device services based on the voice call content.

In addition, if the digital assistant 100 determines the voice command and the result of performing the voice recognition function includes a voice command for connecting a call, the digital assistant 100 connects the call corresponding to the incoming call. A response signal for the request is generated and transmitted to the service server 200.

Additionally, when the call connection with a specific calling terminal 300 fails in response to the response signal, the digital assistant device 100 receives information indicating that the call connection failed, transmitted from the service server 200.

Additionally, the digital assistant device 100 outputs information indicating that the received call connection has failed.

In addition, when the first call path with the calling terminal 300 is normally connected under the control of the service server 200, the digital assistant device 100 is connected to communication via the service server 200 and the telecommunication company server 400. A call function is performed with the calling terminal 300.

Additionally, when the call between the digital assistant device 100 and the calling terminal 300 is terminated, the digital assistant device 100 terminates the previously established call connection with the calling terminal 300.

At this time, the digital assistant device 100 can recognize the called party's voice command and, if the voice command is a command related to ending the call, blocks the call connection and terminates the call connection.

Meanwhile, the telecommunication company server 400 receives a call originating signal from the calling terminal 300.

In addition, the telecommunication company server 400 may be configured to include an additional service server or may be configured to interoperate with the additional service server through communication with the additional service server, and may be configured to include a plurality of different incoming calls pre-stored in the additional service server. Among the identification information of the auxiliary device, the identification information of the digital assistant device 100 corresponding to the called number according to the previously received call outgoing signal is checked in correspondence with the call outgoing signal.

Here, the identification information of the digital assistant device 100 includes mobile IP, mobile MAC, serial number, etc.

At this time, if the telecommunication company server 400 does not confirm the identification information of the digital assistant device registered in advance in relation to the called number of the corresponding incoming terminal 500, the telecommunication company server 400 generates a call processing request signal. Instead, the call connection function between the calling terminal 300 and the called terminal 500 can be performed by attempting to connect the call to the called terminal 500.

In addition, as a result of confirmation, if the identification information of the digital assistant device 100 registered in advance in relation to the incoming number of the corresponding incoming terminal 500 is confirmed, the communication company server 400 sends the call via the corresponding service server 200. In order to perform the connection function, a call connection (or call connection) function is performed between the calling terminal 300 and the service server 200.

Meanwhile, the service server 200 communicates with the digital assistant device 100, the calling terminal 300, the telecommunication company server 400, and the called terminal 500.

Additionally, the service server 200 receives a call processing request signal including the called number and identification information of the digital assistant 100 transmitted from the telecommunication company server 400.

In addition, the service server 200 verifies (identifies) the digital assistant device 100 in relation to the identification information of the digital assistant device 100 included in the received call processing request signal, and identifies the incoming call number included in the call processing request signal. The receiving terminal 500 is confirmed based on .

In addition, the service server 200 responds to the call processing request signal from the previous telecommunication company server 400 and establishes a call between the called terminal 500 and the calling terminal 300 corresponding to the called called number based on the previously confirmed called number. At the same time, a connection (or incoming call connection signal) is requested (or transmitted) to the telecommunication company server 400, and at the same time, in response to the call processing request signal, the called party's digital assistant device ( A call connection for a call connection between 100) and the calling terminal 300 is attempted to the digital assistant device 100.
