Description

{System providing recorded information, method thereof and non-transitory computer readable medium having computer program recorded thereon}

The present invention relates to a service system supporting a voice call using a digital assistant device, a method thereof, and a nonvolatile storage medium having recorded thereon a computer program. In particular, the present invention relates to a service system, a method thereof, and a nonvolatile storage medium having recorded thereon a computer program, which performs a call between a digital assistant device and a calling terminal through a voice command of a caller, utilizes a called terminal when connecting a call between the digital assistant device and the calling terminal, but does not allow the actual call to pass through the called terminal.

As home automation using digital assistants such as AI (Artificial Intelligence) speakers becomes more common, and digital assistants are becoming widespread like new home appliances called AI speakers, the need to use digital assistants to make voice calls with desired subjects is increasing. In the case of voice calls using existing digital assistants, it is known that the digital assistant has a phone function, and when you subscribe to a voice call service, you can make voice calls using the digital assistant as an actual phone.

However, this requires configuring phone functions into the digital assistant, as well as subscribing to voice call services that are consistently expensive and cumbersome to subscribe to.

Additionally, 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 service provider to provide services.

In another way, it is also known that a method is used to utilize a voice call terminal owned by the user, where the digital assistant is connected to the voice call terminal via wired/wireless communication, and only the input and output of voice are interfaced.

That is, after a digital assistant device equipped with a speaker and a microphone is connected to a voice call terminal via a known short-range communication method for voice calls such as Bluetooth, and a call is actually connected between the voice call terminal and the terminal of the call recipient, the microphone and speaker of the digital assistant device take the place of the microphone and speaker of the voice call terminal. Therefore, there is a limitation that the voice call terminal and the digital assistant device must be close to each other, and since the subject of the operation such as making or ending a call is the voice call terminal, there is the inconvenience of having to operate the terminal, and there is a limitation that the service server providing the digital assistant device service based on the content of the voice call cannot manage it.

Figure 1 is a block diagram showing the configuration of a service system (10) that supports voice calls using a digital assistant device according to an embodiment of the present invention.

As illustrated in FIG. 1, the service system (10) is composed of a digital assistant device (100), a service server (200), a calling terminal (300), a communication server (400), and a receiving terminal (500). Not all of the components of the service system (10) illustrated in FIG. 1 are essential components, and the service system (10) may be implemented with more components than the components illustrated in FIG. 1, or may be implemented with fewer components.

The calling terminal (300) transmits a call signal to the telecommunications company server (400) with the incoming number corresponding to the called party's incoming terminal (500).

The communication server (400) checks the identification information of the digital assistant device (100) corresponding to the incoming number according to the call outgoing signal from among the identification information of multiple different incoming number-specific digital assistant devices stored in advance based on the incoming number included in the call outgoing signal received from the calling number of the calling terminal (300).

At this time, the communication service server (400) may include an additional service server that supports an additional service for a call connection with the calling terminal (300) through a digital assistant device (100) corresponding to the receiving terminal (500), or the additional service server may be configured separately from the communication service server (400).

In addition, the additional service server may store in advance the identification information of the digital assistant device (100) corresponding to (matching) the incoming number of the incoming terminal (500), and the identification information of the digital assistant device corresponding to each incoming number of a plurality of different incoming callers may be stored in advance in the additional service server.

In addition, the communication company server (400) can generate inquiry information on whether to subscribe to additional services including the incoming number according to the call origination signal and transmit it to the additional service server.

Accordingly, the additional service server searches for identification information of digital assistant devices for each incoming number stored in advance based on the incoming number included in the inquiry information, extracts identification information of a digital assistant device (100) corresponding to the incoming number according to the inquiry information, and then generates search result information including identification information of the extracted digital assistant device (100) and provides the search result information to the telecommunications company server (40 0).

Through this, the communication server (400) can confirm that the corresponding incoming number is subscribed to an additional service for call connection using a digital assistant device if the search result information includes identification information of the digital assistant device (100), and can transmit a call processing request signal including the calling number of the calling terminal (300), the incoming number according to the call origination signal, and the identification information of the digital assistant device (100) according to the search result information to the service server (200).

At this time, if the identification information of the digital assistant device (100) corresponding to the incoming number is not searched by the additional service server based on the search result information, the communication server (400) can transmit the incoming call to the incoming terminal (500) in response to the call transmission signal of the incoming terminal (300) for call connection between the incoming terminal (300) and the incoming terminal (500).

In addition, the service server (200) can check the digital assistant device (100) related to the called number and called party information included in the call processing request signal transmitted from the telecommunications company server (400).

In addition, the service server (200) may attempt to connect a call to the incoming terminal (500) corresponding to the incoming number of the incoming terminal (500) identified based on the call processing request signal through the telecommunications company server (400) and may also attempt to connect a call to the digital assistant device (100) identified based on the call processing request signal.

In addition, the service server (200) performs a call connection function between the telecommunications company server (400) and the digital assistant device (100) based on a response signal received in response to a call connection from a digital assistant device (100) corresponding to the receiving terminal (500) that recognizes the voice command of the called party for a call connection request, and can request a call connection between the calling terminal (300) and the digital assistant device (100) to the telecommunications company server (400).

At this time, when the communication server (400) receives a call connection request signal related to a call connection request between the digital assistant device (100) of the callee who transmitted the response signal from the service server (200) and the calling terminal (300), the communication server can form a first call path between the digital assistant device (100) and the calling terminal (300) in response to the call connection request signal.

Here, the request signal related to the call connection may also be the above response signal.

In addition, the service server (200) can maintain a first call path, which is a call path between the digital assistant device (100) and the calling terminal (300) formed through the communication service server (400) in response to the requested call connection through communication with the communication service server (400), and the service server (200) can mediate voice transmitted and received through the first call path together with the communication service server (400).

That is, the communication server (400) can connect the first call path (or communication path or call session) between the digital assistant device (100), the service server (200), the communication server (400), and the calling terminal (300).

At this time, the telecommunications server (400) connects a second call path between the calling terminal (300), the telecommunications server (400), and the called terminal (500) independently and in parallel for charging fees while connecting the first call path, thereby maintaining the second call path (call session) between the called terminal (500) and the called terminal (300) and stopping the transmission of the incoming call to the called terminal (500).

The digital assistant device (100) includes an AI (Artificial Intelligence) speaker/microphone, a microcontroller (or control unit) (not shown), a communication unit (not shown), a storage unit (not shown), etc.

In addition, the digital assistant device (100) communicates with the service server (200), sending terminal (300), etc. through wired/wireless communication.

Here, the receiving terminal (500) corresponding to the digital assistant device (100) can register information related to the receiving terminal (500) (or receiving party information) in advance in the digital assistant device (100).

In addition, if the voice command (or voice) of the recipient received by the digital assistant device (100) is a voice command for call connection for a call with the calling terminal (300), the digital assistant device (100) transmits a response signal including identification information of the digital assistant device (100) according to the voice command to the service server (200). Here, the identification information of the digital assistant device (100) includes a mobile IP, mobile MAC, serial number, etc.

That is, the digital assistant device (100) receives a voice from a called party (or user) and performs a voice recognition function for the received voice. At this time, the digital assistant device (100) checks whether the voice received from the called party is a voice of a pre-registered user (or user authentication) based on pre-stored called party information, and if the received voice corresponds to a voice of a pre-registered user, it may perform a voice recognition function for the received voice. Here, the voice recognition function may be performed using various known technologies.

Additionally, the digital assistant device (100) determines whether the result of performing the voice recognition function includes a voice command for call connection.

As a result of the judgment, if the result of performing the voice recognition function includes a voice command for performing another control function related to the digital assistant device (100), the digital assistant device (100) performs another control function related to the digital assistant device (100) corresponding to the voice command.

For example, if the judgment result is that the result of performing the voice recognition function includes the voice command “Ariya, turn up the volume by one level,” the digital assistant device (100) raises the speaker output of the digital assistant device (100) by a preset level of one and outputs it. Here, “Ari” may be identification information (or identification name) for the digital assistant device (100).

Additionally, the digital assistant device (100) can output a preset sound corresponding to an incoming call when receiving an incoming call for a call connection attempt from the service server (200).

In addition, if the digital assistant device (100) determines that the voice command for call connection is included in the result of the voice recognition function performed based on the judgment result for the voice command, the digital assistant device (100) generates a response signal for a call connection request corresponding to the incoming call and transmits it to the service server (200).

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

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

In addition, when the first call route with the calling terminal (300) is normally connected by the control of the service server (200), the digital assistant device (100) performs a call function with the calling terminal (300) connected to the communication via the service server (200) and the communication company server (400).

Additionally, when a 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 voice command of the called party and, if the voice command is a command related to call termination, can end the call connection by blocking the call connection.

Meanwhile, the telecommunications server (400) receives a call transmission signal from the calling terminal (300).

In addition, the communication server (400) may be configured to include an additional service server or may be configured to be linked with an additional service server through communication with the additional service server, and among the identification information of a plurality of different incoming number-specific digital assistant devices pre-stored in the additional service server, the identification information of a digital assistant device (100) corresponding to an incoming number according to a previously received call outgoing signal is checked in response to the call outgoing signal.

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

In addition, the communication server (400) generates a call processing request signal including identification information of the digital assistant device (100) confirmed in response to the call outgoing signal and the incoming number of the incoming terminal (500) and transmits it to the service server (200).

At this time, if the communication service server (400) determines that the identification information of the pre-registered digital assistant device is not confirmed in relation to the incoming number of the corresponding incoming terminal (500), the communication service server (400) may attempt to connect a call to the incoming terminal (500) without generating a call processing request signal, thereby performing a call connection function between the calling terminal (300) and the incoming terminal (500).

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

Meanwhile, the service server (200) communicates with a digital assistant device (100), a calling terminal (300), a telecommunications company server (400), a called terminal (500), etc.

In addition, the service server (200) receives a call processing request signal including a call number transmitted from a telecommunications company server (400), identification information of a digital assistant device (100), etc.

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

In addition, the service server (200) requests (or transmits) a call connection (or an incoming call connection signal) between the receiving terminal (500) and the calling terminal (300) corresponding to the incoming number confirmed in advance in response to a call processing request signal from the preceding telecommunications server (400), and at the same time, in response to the call processing request signal, attempts to establish a call connection for the call between the digital assistant device (100) of the calling party and the calling terminal (300) based on the identification information of the digital assistant device (100) confirmed in advance, for the digital assistant device (100).

Additionally, the service server (200) may form (or configure) a first call path between the digital assistant device (100) and the calling terminal (300) via the telecommunications company server (400) when receiving a response signal for a call connection attempt from the digital assistant device (100).

At this time, the service server (200) may receive a response signal from the digital assistant device (100) and generate a call connection request signal for a call connection between the digital assistant device (100) and the calling terminal (300) based on the response signal and transmit the signal to the telecommunications server (400). When the telecommunications server (400) forms a first call path between the digital assistant device (100) and the calling terminal (300) via the service server (200) and the telecommunications server (400) based on the call connection request signal, the telecommunications server may stop the call connection attempt for the called terminal (500) and form a second call path different from the first call path in parallel between the called terminal (300) and the called terminal (500), but may form the second call path in an idle state (or call standby state) in which no signal is transmitted or received.

Additionally, the communication server (400) can interconnect the first call route and the second call route.

In addition, when a call between the digital assistant device (100) and the calling terminal (300) is terminated for the first call route formed between the digital assistant device (100) and the calling terminal (300) via the service server (200) and the communication company server (400), the first call route (or call connection status) and the second call route can be terminated (or released/terminated).

The calling terminal (or transmitting terminal) (300) and the called terminal (or receiving terminal) (500) may be a smart phone, a portable terminal, a mobile terminal, a personal digital assistant (PDA), a portable multimedia player (PMP) terminal, a telematics terminal, a navigation terminal, a personal computer, a notebook computer, a slate PC, a tablet PC, an ultrabook, a wearable device (e.g., a smartwatch, a smart glass, a head mounted display (HMD), etc.), a Wibro terminal, an IPTV (Internet Protocol Television) terminal, a smart TV, a digital broadcasting terminal, a television, a 3D television, a home theater system, an AVN (Audio Video Navigation) terminal, It can be applied to various terminals such as A/V (Audio/Video) systems and flexible terminals.

In addition, the control unit (350) can generate and transmit a call signal including the incoming number through the communication unit (310) based on the phone book stored in the storage unit (320) and the incoming number of the recipient selected by the user.

Through this, based on the call transmission signal transmitted from the communication unit (310), the communication company server (400) can confirm the digital assistant device (100) and the receiving terminal (500) based on the called party information corresponding to the called number, and perform a call connection between the confirmed digital assistant device (100) and the calling terminal (300) and between the confirmed called terminal (500) and the calling terminal (300).

In addition, when a first call path is formed between a digital assistant device (100), a service server (200), a communication server (400), and a calling terminal (300) through the mediation (or relay) of a communication server (400), the communication unit (310) forms a second call path between the calling terminal (300), the communication server (400), and a called terminal (500) in parallel with the first call path through the mediation of the communication server (400).

At this time, another second call between the calling terminal (300) and the receiving terminal (500) may be formed to pay the cost of the call between the digital assistant device (100) and the calling terminal (300), and the digital assistant device (100) and the calling terminal

When a call between (300) is terminated, the other second call is also terminated, and cost settlement for the call between the digital assistant device (100) and the called terminal (500) can be performed by the telecommunications company server (400).

Here, the communication server (400) may stop the call connection attempt to the called terminal (500) when the first call is formed by the response signal of the digital assistant device (100), form a second call path between the calling terminal (300) and the called terminal (500), and then maintain the second call path in an idle state where no signal transmission or reception is performed until the first call path is terminated.

Through this, the calling terminal (300) can perform an actual voice call function with the digital assistant device (100), and while the call function with the digital assistant device (100) is maintained, the second call path, which is another communication path, can be maintained in the background state with the called terminal (500).

Meanwhile, the communication server (400) communicates with the service server (200), the calling terminal (300), the receiving terminal (500), etc.

In addition, the communication server (400) may include a configuration for a communication unit (310), a storage unit (320), a display unit (330), a voice output unit (340), and a control unit (350) included in the sending terminal (300).

Additionally, the communication server (400) receives a call transmission signal transmitted from the calling terminal (300).

That is, the communication server (400) receives a call transmission signal including the incoming number of the receiving terminal (500) transmitted from the sending terminal (300).

Additionally, the telecommunications server (400) verifies the called party's information based on the received call signal.

The communication server (400) checks the identification information of the digital auxiliary device (100) corresponding to the incoming number among the identification information of multiple different incoming number-specific digital auxiliary devices stored in advance based on the incoming number included in the call signal received from the calling number of the calling terminal (300).

To this end, the telecommunications company server (400) stores (or manages) caller information related to a receiving terminal (500) that has registered as a member to use an additional service that supports calls using a digital assistant device (100) on the telecommunications company server (400).

At this time, the identification information of the receiving terminal (500) corresponding to the receiving party and the identification information of the digital assistant device (100) corresponding to the receiving party may be included in the receiving party information in a mutually matched state and stored in the telecommunications company server (400).

Here, the caller information of a callee who has not subscribed to the additional service may be stored without identification information of the digital assistant device (100).

Here, the identification information of the receiving terminal (500) may include multiple different attribute-specific parameters for the receiving number (or phone number or MDN (Mobile Directory Number)), mobile IP, mobile MAC, SIM (subscriber identity module) card unique information, serial number, etc.

In the above-described configuration, the telecommunications company server (400) may include a separate additional service server for subscription confirmation (registration confirmation) of an additional service that supports calls using a digital assistant device (100), or the additional service server may be configured separately from the telecommunications company server (400) and configured to be linked through mutual communication with the telecommunications company server (400), and the additional service server may store the corresponding recipient information.

That is, the identification information of the digital assistant device (100) corresponding to (matched with) the incoming number of the incoming terminal (500) can be stored in advance in the additional service server, and the identification information of the digital assistant device corresponding to each incoming number of a plurality of different incoming callers can be stored in advance in the additional service server.

Accordingly, when the communication server (400) receives a call outgoing signal from the calling terminal (300), the communication server (400) confirms the caller information of a plurality of different callees based on the incoming number corresponding to the call outgoing signal through linkage with the additional service server, and can confirm the incoming terminal (500) and digital assistant device (100) of the specific callee based on the caller information of the specific callee searched in response to the incoming number corresponding to the call outgoing signal, and transmits a call processing request signal including identification information of the digital assistant device (100) related to the incoming number and caller information for requesting a call connection attempt to the digital assistant device (100) and the incoming terminal (500) confirmed in response to the call outgoing signal to the service server (200).

In addition, when the communication server (400) receives an incoming call connection signal related to a call connection attempt for the called terminal (500) of the service server (200) in response to the corresponding call processing request signal from the service server (200), the communication server (400) can mediate the call connection attempt of the service server (200) for the called terminal (500) by transmitting the incoming call to the called terminal (500) that matches the digital assistant device (100) according to the called party information in response to the incoming call connection signal.

In addition, when the communication server (400) receives a response signal or a call connection request signal from the digital assistant device (100) from the corresponding service server (200) in response to a call connection attempt to the digital assistant device (100) that is made simultaneously with a call connection attempt to the called terminal (500) by the service server (200), the communication server (400) can form a first call path between the digital assistant device (100) and the calling terminal (300) via the service server (200) and the communication server (400), and can stop the call connection attempt to the called terminal (500) simultaneously with the formation of the first call path and form a second call path that is automatically linked to the first call path, and can maintain the second call path in an idle state.

Additionally, the communication server (400) can terminate the second call route together when the call connection to the first call route is terminated through communication with the service server (200).

Meanwhile, in the above-described configuration, a plurality of different terminal-specific identification information may be registered in the recipient information of a specific recipient by matching one incoming number, and a plurality of different terminal-specific identification information corresponding to a specific recipient may be included in the recipient information of a specific recipient in a state of being matched with the identification information of a digital assistant device (100) corresponding to the specific recipient.

At this time, if identification information for each of a plurality of different receiving terminals (500) corresponding to a specific receiving party is included in the receiving party information, the identification information for each of a plurality of different receiving terminals (500) corresponding to each of a plurality of different receiving terminals may have only the receiving number (telephone number) as the same, and the remaining attributes may have different parameters.

Through this, the communication service server (400) can check the recipient information corresponding to the recipient number according to the call origination signal of the calling terminal (300) when the calling terminal (300) attempts to call the recipient number (telephone number) corresponding to a specific recipient, and if multiple different recipient terminals (500) excluding the digital assistant device (100) are registered in the recipient information, generate a call processing request signal including identification information of each of the multiple different recipient terminals (500) and transmit it to the service server (200).

Accordingly, the service server (200) can attempt to establish a call connection in parallel with the digital assistant device (100) for each of a plurality of different incoming terminals (500) through the telecommunications server (400).

In addition, when the communication server (400) responds to a call connection attempted in parallel for each of the digital assistant device (100) and a plurality of different receiving terminals (500) corresponding to a single incoming number through communication with the service server (200), the communication server (400) can individually form an idle call path for each of the plurality of different receiving terminals (500) corresponding to a specific receiving party in addition to the first call path for call connection between the digital assistant device (100) and the calling terminal (300) of the specific receiving party as described above.

In addition, when a call connection between a digital assistant device (100) and a calling terminal (300) is terminated through communication with a service server (200), the communication server (400) can terminate all call paths formed for each of a plurality of receiving terminals (500).

Meanwhile, the service server (200) performs a call connection function between the digital assistant device (100) and the telecommunications server (400) based on an incoming call connection (or incoming call connection request) requested from the telecommunications server (400) in response to a previously transmitted call processing request signal.

In this way, when a call connection between a digital assistant device (100) and a communication server (400) is normally performed by the service server (200), the first call path between the digital assistant device (100), the service server (200), the communication server (400), and the calling terminal (300) can be normally connected.

At this time, when the digital assistant device (100) and the calling terminal (300) are connected to the call via the service server (200) and the telecommunications server (400), the service server (200) (or the telecommunications server (400)) can be configured to maintain the state in which the calling terminal (300) and the called terminal (500) are connected to the call via the telecommunications server (400).

Meanwhile, the digital assistant device (100) can recognize a user's voice command during a call connection with the calling terminal (300) according to the connection to the first call, and if the voice command is a request for recording of the call content, generate a recording request signal and transmit it to the service server (200).

At this time, the digital assistant device (100) may transmit the recording request signal to the service server (200) through a communication network or channel separate from the first call.

Accordingly, when the service server (200) receives a recording request signal from a digital assistant device (100), the service server (200) can record a voice signal transmitted and received through the first call path connected to the digital assistant device (100) that transmitted the recording request signal, and can generate and store recording information according to the recording of the voice signal.

At this time, when a video call is made between a digital assistant device (100) and a calling terminal (300) through the first call path, the service server (200) can record the video and voice and store the generated video information as the corresponding recording information.

In addition, the service server (200) can store the recording information by matching at least one of the identification information of the digital assistant device (100) included in the recording request signal and the phone number of the receiving terminal (500).

In addition, when the service server (200) receives request information for provision of recording information including at least one of identification information of a digital assistant device (100) and a telephone number of the receiving terminal (500) from the receiving terminal (500), the service server (200) can transmit the confirmed recording information corresponding to the request information to the receiving terminal (500).

At this time, even if the service server (200) receives a request for provision of recording information from the sending terminal (300), it can transmit the corresponding recording information to the sending terminal (300).

Through the above-described configuration, if the receiving terminal (500) and/or digital assistant device (100) does not support a recording function, the call content can be recorded through the service server (200), thereby improving user convenience.

Meanwhile, as illustrated in FIG. 3, when the sending terminal (300) and the receiving terminal (500) are subscribed to different telecommunication companies, a plurality of different telecommunication company servers (400) are configured between the sending terminal (300) and the receiving terminal (500), and a call connection between the sending terminal (300), the plurality of different telecommunication company servers (400), and the receiving terminal (500) may be maintained by mutual interconnection (or mutual communication connection) of the plurality of different telecommunication company servers (400).

In addition, when the call connection between the digital assistant device (100) and the receiving terminal (500) is terminated, the communication service server (400) terminates the connection of the communication path between the digital assistant device (100), the service server (200), the communication service server (400), and the calling terminal (300) that are connected in parallel, and the connection of the communication path between the calling terminal (300), the communication service server (400), and the called terminal (500).

That is, when the call connection between the digital assistant device (100) and the calling terminal (300) is terminated, the telecommunications server (400) terminates the call connection between the digital assistant device (100), the service server (200), the telecommunications server (400), and the calling terminal (300), and after the call connection is terminated, terminates the call connection between the calling terminal (300), the telecommunications server (400), and the called terminal (500).

Additionally, after the entire call connection type, the telecommunications company server (400) charges the call fee related to the call connection to the calling terminal (300) and/or the called terminal (500).

Meanwhile, the receiving terminal (500) communicates with a digital assistant device (100), a service server (200), a calling terminal (300), a telecommunications company server (400), etc.

In addition, the receiving terminal (500) may include a configuration for a communication unit (310), a storage unit (320), a display unit (330), a voice output unit (340), and a control unit (350) included in the sending terminal (300).

Accordingly, the control unit configured in the receiving terminal (500) can communicate with the communication service server (400) through the communication unit and transmit registration information including identification information about the digital assistant device (100) used by the receiving terminal (500) to the receiving party information corresponding to the receiving terminal (500) pre-registered in the communication service server (400).

Accordingly, the telecommunications company server (400) that receives registration information from the receiving terminal (500) can update and store the receiving information by including identification information of the digital assistant device (100) by matching the receiving number with the pre-registered and pre-stored receiving information.

At this time, the communication company server (400) can update the callee information by including the identification information of the digital assistant device (100) in the caller information based on the registration information by linking with the additional service server.

Additionally, the receiving terminal (500) forms a second call path with the calling terminal (300) through the mediation of the telecommunications company server (400).

At this time, before the first call path is formed between the digital assistant device (100) and the calling terminal (300) through the mediation of the communication service server (400), the called terminal (500) can be configured to output the caller information for the calling terminal (300) transmitted from the communication service server (400) (or service server (200)) so that the called party of the called terminal (500) can confirm the caller information requesting the call connection.

In addition, when the call between the calling terminal (300) and the digital assistant device (100) is terminated, the called terminal (500) terminates the call with the calling terminal (300) under the control of the telecommunications company server (400).

In the embodiment of the present invention, when a call is connected between a digital assistant device (100) and a calling terminal (300), a voice call is described as an example, but it is not limited thereto. In addition to a voice call, if the digital assistant device (100) is equipped with a display unit (not shown), a video call (or image call) may be performed between the digital assistant device (100) and the calling terminal (300).

In addition to voice calls and/or video calls, functions such as sending emails between a digital assistant device (100) and an email server (not shown), and posting/commenting on a social network account related to the sending terminal (300) between a digital assistant device (100) and a social network server (not shown) may also be performed.

In addition, the calling terminal (300) and/or the called terminal (500) may further include an interface unit (not shown) that functions as an interface with all external devices connected to the calling terminal (300) and/or the called terminal (500). For example, the interface unit may be composed of a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for connecting a device equipped with an identification module, an audio I/O (Input/Output) port, a video I/O (Input/Output) port, an earphone port, etc. Here, the identification module is a chip that stores various types of information for authenticating the usage rights of the calling terminal (300) and/or the called terminal (500), and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), etc. In addition, a device equipped with an identification module can be manufactured in a smart card format. Accordingly, the identification module can be connected to a sending terminal (300) and/or a receiving terminal (500) through a port. Such an interface unit receives data or receives power from an external device and transmits it to each component inside the sending terminal (300) and/or the receiving terminal (500) or transmits it to the sending terminal (300) and/or the receiving terminal

(500) Allows internal data to be transmitted to an external device.

In addition, the interface unit may be a passage through which power from the cradle is supplied to the sending terminal (300) and/or the receiving terminal (500) when the sending terminal (300) and/or the receiving terminal (500) are connected to an external cradle, or may be a passage through which various command signals input by the user from the cradle are transmitted to the sending terminal (300) and/or the receiving terminal (500). Various command signals or the corresponding power input from the cradle may also be operated as signals for recognizing that the sending terminal (300) and/or the receiving terminal (500) is correctly mounted in the cradle.

In addition, the sending terminal (300) and/or the receiving terminal (500) may further include an input unit (not shown) for receiving a signal according to a button operation or selection of an arbitrary function by the user, or for receiving a command or control signal generated by an operation such as touching/scrolling a displayed screen.

The input unit is a means for receiving at least one of a user's command, selection, data, or information, and may include a plurality of input keys and function keys for receiving numeric or character information and setting various functions.

In addition, the input unit may use various devices such as a key pad, a dome switch, a touch pad (static/capacitive), a touch screen, a jog wheel, a jog switch, a jog shuttle, a mouse, a stylus pen, a touch pen, etc. In particular, when the display unit (330) is formed in the form of a touch screen, some or all of the input functions may be performed through the display unit (330).

In addition, each component (or module) of the sending terminal (300) may be software stored on the memory (or storage) of the sending terminal (300) and/or the receiving terminal (500). The memory may be an internal memory of the sending terminal (300) and/or the receiving terminal (500), an external memory, or another type of storage device. In addition, the memory may be a non-volatile memory. The software stored on the memory may include a set of commands that cause the sending terminal (300) and/or the receiving terminal (500) to perform a specific operation when executed.

In addition, the service server (200) and the communication server (400) may be implemented in the form of a web server, a database server, a proxy server, etc. In addition, the service server (200) and the communication server (400) may be installed with one or more of a network load distribution mechanism, or various software that allows the service server (200) and the communication server (400) to operate on the Internet or other networks, thereby enabling the service server (200) and the communication server (400) to be implemented as a computerized system. In addition, the network may be an http network, a private line, an intranet, or any other network. Furthermore, the connection between the service server (200) and the communication server (400) and the calling terminal (300) and/or the called terminal (500) may be connected to a secure network so that the data is not attacked by any hacker or other third party. Additionally, the service server (200) and the communication server (400) may include a plurality of database servers, and these database servers may be implemented in a manner in which they are separately connected to the service server (200) and the communication server (400) via any type of network connection, including a distributed database server architecture.

In addition, the processor mounted on the digital assistant device (100), the service server (200), the calling terminal (300), the communication company server (400), and the called terminal (500) according to the present invention can process a program command for executing the method according to the present invention. In one implementation example, the processor can be a single-threaded processor, and in another implementation example, the processor can be a multi-threaded processor. Furthermore, the processor can process a command stored in a memory or a storage device.

In this way, when a call is connected between a digital assistant device (100) and a calling terminal (300) through the overall control of the service server (200), the called terminal (500) is utilized, but the actual call does not pass through the called terminal (500), and the call between the digital assistant device (100) and the calling terminal (300) can be performed through a voice command of the called party.

In addition, in this way, when a call is connected between a digital assistant device (100) and a calling terminal (300) by the overall control of the service server (200), the call connection between the calling terminal (300) and the called terminal (500) is maintained in parallel, and the service server (200) and/or the communication server (400) can provide a call reception notification to the called terminal (500) by using the phone number of the calling terminal (300) as the calling number.

Hereinafter, a service method for supporting voice calls using a digital assistant device according to the present invention will be described in detail with reference to FIGS. 1 to 3 and through FIGS. 4 and 5.

FIG. 4 is an exemplary operation diagram of a service system (10) supporting a voice call using a digital assistant device (100) according to an embodiment of the present invention, and FIG. 5 is a flowchart illustrating a service method supporting a voice call using a digital assistant device (100) according to an embodiment of the present invention.

First, the calling terminal (300) can generate a call signal including the incoming number of the receiving terminal (500) selected by the user and transmit it to the telecommunications company server (400) (S1).

In addition, when receiving a call signal, the communication company server (400) can directly check whether there is caller information registered (subscribed) to a supplementary service that supports calls using a digital assistant device (100) corresponding to the corresponding call number based on the call number of the call terminal (500) included in the call signal, or can check this through linkage with the supplementary service server (S2).

In addition, if there is called party information corresponding to the called number according to the call origination signal, the communication server (400) can generate a call processing request signal including the called number of the called terminal (500) included in the called party information, the identification information of the digital assistant device (100), and the calling number of the calling terminal (300), and then transmit the signal to the service server (200) (S3).

At this time, the identification information of the digital assistant device (100) includes mobile IP, mobile MAC, serial number, etc.

In addition, when the service server (200) receives a call processing request signal from a telecommunications company server (400), it determines that the additional service is being used, and can check the call number of the incoming terminal (500) and the identification information of the digital assistant device (100) included in the call processing request signal.

In addition, the service server (200) may attempt to connect a call to a digital assistant device (100) corresponding to the identification information of the digital assistant device (100) according to the call processing request signal, and may also attempt to connect a call to a called terminal (500) confirmed to correspond to the call processing request signal through the telecommunications company server (400) (S4).

For example, the service server (200) requests (or transmits) to the telecommunications server (400) an incoming call connection (or an incoming call connection signal) with the incoming terminal (500) corresponding to the incoming number based on the previously confirmed incoming number in response to a call processing request signal from the telecommunications server (400), and the telecommunications server (400) transmits the incoming call to the incoming terminal (500) in response to the incoming call connection.

Meanwhile, the digital assistant device (100) can output an incoming call notification sound and incoming call notification information, etc. according to an incoming call received from the service server (200) according to a call connection attempt of the service server (200).

To this end, the digital assistant device (100) may be configured to include an output unit for outputting a notification sound or notification information for receiving an incoming call to the called party when receiving an incoming call. At this time, the output unit may include a display means such as a speaker and a display.

Additionally, the digital assistant device (100) receives a voice from a caller (or user) and performs a voice recognition function for the received voice.

At this time, the digital assistant device (100) can check whether the received voice is the voice of a pre-registered user (or authenticate the user), and if the received voice corresponds to the voice of a pre-registered user, can perform a voice recognition function for the received voice.

Additionally, the digital assistant device (100) determines whether the result of performing the voice recognition function includes a voice command for call connection.

As a result of the judgment, if the result of performing the voice recognition function includes a voice command for call connection, the digital assistant device (100) generates a response signal corresponding to the incoming call received from the service server (200) in response to the call connection attempt of the service server (200) and transmits it to the service server (200) (S5).

At this time, if the judgment result is that the result of performing the voice recognition function includes a voice command for performing another control function related to the digital assistant device (100), the digital assistant device (100) performs another control function related to the digital assistant device (100) corresponding to the voice command.

As an example of this, the digital assistant device (100) receives a voice from a called party (e.g., “Ariya, answer the phone”) and performs a voice recognition function for the received voice.

In addition, the digital assistant device (100) determines whether the result of the voice recognition function execution includes a voice command for call connection, and when it is determined that the result of the voice recognition function execution includes a voice command for call connection (e.g., “answer the call”) for a call with the calling terminal (300), it generates a response signal corresponding to the incoming call and transmits it to the service server (200).

Thereafter, when the service server (200) receives a response signal transmitted from the digital assistant device (100), it may transmit the response signal to the telecommunications server (400) or generate a call connection request signal corresponding to the response signal to request a call connection between the digital assistant device (100) and the calling terminal (300) and transmit the signal to the telecommunications server (400) (S6).

Here, when the communication server (400) performs a call connection function with the corresponding receiving terminal (500) based on the incoming call connection requested from the service server (200) to the receiving terminal (500), the communication server (400) (or the service server (200)) provides the receiving terminal (500) with caller information (including, for example, the phone number of the calling terminal (300)) related to the calling terminal (300) based on the calling number confirmed when the call processing request signal was generated, so that the receiving terminal (500) can check the caller information corresponding to the calling number before the call connection.

In addition, when the communication server (400) receives a response signal or a call connection request signal from the service server (200) rather than the called terminal (500) in response to the call processing request signal, the communication server (400) determines that a call connection between the digital assistant device (100) and the calling terminal (300) has been established, and can form a first call path for a call connection between the digital assistant device (100) and the calling terminal (300) through communication with the service server (200) (S7).

In addition, when the digital assistant device (100) and the calling terminal (300) are connected to a call via the service server (200) and the telecommunications server (400), the service server (200) (or the telecommunications server (400)) can form a second call path in parallel to maintain the calling terminal (300) and the called terminal (500) in a call-connected state via the telecommunications server (400) (S8).

At this time, the communication server (400) can maintain an idle state for the second call route.

Thereafter, when the call connection between the digital assistant device (100) and the calling terminal (300) is terminated (S9), the communication service server (400) terminates (or releases) the connection (or call connection) between the digital assistant device (100), the service server (200), the communication service server (400), and the calling terminal (300) that are connected in parallel, and the first call route between the calling terminal (300), the communication service server (400), and the called terminal (500) (S10).

That is, when the call connection between the digital assistant device (100) and the calling terminal (300) is terminated, the telecommunications server (400) terminates the call connection between the digital assistant device (100), the service server (200), the telecommunications server (400), and the calling terminal (300), and after the call connection is terminated, terminates the call connection between the calling terminal (300), the telecommunications server (400), and the called terminal (500).

Additionally, after the entire call connection type, the telecommunications company server (400) charges the call fee related to the call connection to the calling terminal (300) and/or the called terminal (500).

In this way, an actual call is made between the digital assistant device (100) and the calling terminal (300), but since the calling terminal (300) related to the digital assistant device (100) maintains a communication state with the corresponding receiving terminal (500), the telecommunications company server (400) can perform a function of charging a fee for a call between the digital assistant device (100) and the calling terminal (300) (or a function of paying a call fee for a call between the digital assistant device (100) and the calling terminal (300)) through the corresponding receiving terminal (500).

A service system supporting a voice call using a digital assistant device according to an embodiment of the present invention can be written as a computer program, and codes and code segments constituting the computer program can be easily inferred by a computer programmer in the relevant field. In addition, the computer program is stored in a computer readable media, and is read and executed by a computer, a digital assistant device according to an embodiment of the present invention, a service server, a calling terminal, a telecommunications company server, a called terminal, etc., thereby implementing a service system supporting a voice call using a digital assistant device.

The information storage medium includes a magnetic recording medium, an optical recording medium, etc. The computer program implementing the service system supporting a voice call using a digital assistant device according to an embodiment of the present invention may be stored and installed in the built-in memory of the digital assistant device, a service server, a calling terminal, a telecommunications company server, a called terminal, and the like. Alternatively, an external memory such as a smart card storing and installing the computer program implementing the service system supporting a voice call using a digital assistant device according to an embodiment of the present invention may be mounted on the service system supporting a voice call using a digital assistant device, etc., through an interface.

As described above, in an embodiment of the present invention, when a call is connected between a digital assistant device and a calling terminal by the overall control of a service server, the called terminal is utilized, but the actual call does not go through the called terminal, and the call between the digital assistant device and the calling terminal is performed through a voice command of the called party, so that the called party can freely perform a call with the calling terminal through the digital assistant device without the need to operate or control the called terminal, thereby increasing the convenience of use.

In addition, since the embodiment of the present invention can provide recording information about the call content generated by recording the call content between the caller and the caller by the service server that connects the call between the digital assistant device and the calling terminal instead of the called terminal as described above, the user convenience for recording can be improved by providing the recording function through the service server even when the called terminal or the digital assistant device does not support the recording function.

The above-described contents can be modified and changed by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to explain it, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the rights of the present invention.
