FIG. 1A is a configuration diagram illustrating a user call support system based on an identification code according to an embodiment of the present invention, and FIGS. 1B to 1G are views showing an example of identification code exposure according to an embodiment of the present invention. 1H and 1I are views showing a web page-based connection method according to an embodiment of the present invention.

As shown in FIG. 1A, a user call support system 10 based on an identification code includes a subscriber terminal 300, a caller terminal 100, and a relay device 200.

The subscriber terminal 300 is a communication terminal to be used for a user call registered by a user subscribed to the call relay service. For example, the subscriber terminal 300 may be a cellular phone, a public telephone, a computer (PC), a web server, or an Internet of Things device.

Specifically, the subscriber terminal 300 can subscribe to the call relay service through the relay device 200, register the contact of the communication terminal, and be given an identification code to be exposed in place of the real contact. Thereafter, the identification code may be exposed on behalf of the real contact at a location to expose the user ' s real contact and used for a user call by the call relay service. At this time, the subscriber can print the identification code on paper or the like and attach it to the offline specific place, or upload it to the site for online transaction or the like.

Here, the identification code may be at least one kind of a one-dimensional bar code, a two-dimensional bar code, and a QR code. In addition, the identification code may be a unique code that is not overlapped by each subscriber configured with a predetermined length (for example, 16 to 1024 lengths) according to the type thereof.

1B to 1G, the specific location may include a contact information (FIG. 1B) for a borrower call, fault manager information (FIG. 1C) of public equipment (ATM, etc.), public utilities (eg, street lights, traffic lights, (Fig. 1D), the courier box contact information, the advertising agent information of the promotional leaflet (Fig. 1E), the offline store manager's absence contact (Fig. 1F), and the promotional product order information It can be a place. Here, the service extension range according to the present invention is not limited to this, and may vary according to the application method.

The caller terminal 100 is a terminal of a person who wants to call a user by using an identification code. The caller terminal 100 scans an identification code exposed to a specific place or a specific web by a subscriber using a preset application APP according to an operation of a caller and transmits the ID code to the relay device 200 using the scanned identification code Request a subscriber call.

At this time, the caller terminal 100 may scan the identification code using a predetermined application capable of scanning the identification code, and may call the subscriber corresponding to the identification code. For example, if the identification code is a QR code, the predetermined application may be a QR code scanable application.

For example, the caller terminal 100 may be a cellular phone, a public telephone, a computer (PC), a web server, or a stuff Internet device.

When the caller terminal 100 confirms the call request of one subscriber corresponding to the scanned identification code, the relay apparatus 200 transmits a call or character connection to the telephone number corresponding to the scanned identification code, (APP) -based VoIP call connection, a chat connection, or a call back connection to the caller terminal 100 in response to a request from the subscriber terminal 100.

Alternatively, the relay apparatus 200 may provide the caller terminal 100 with a predetermined web page by one subscriber. A more detailed configuration of the relay apparatus 200 will be described later with reference to FIG. 2A.

Here, the predetermined web page may be a user custom page or a user information disclosure page. At this time, the web page may be simply a page composed of HTML, css, JavaScript, pictures, etc., and may be any HTTP-based page such as an HTTP based HTML web app, an app based native web and a hybrid app.

First, the user custom page of the former may be a web page that further includes an interface that provides information set by the user but is selectively set by the caller. For example, as shown in FIG. 1H, the user custom page may be a web page in which when a user reports a failure of an ATM device, the failure type is selected and the failure is reported. Accordingly, in the present invention, the central control center for confirming a fault report can easily confirm which equipment is in which location, and can assist the repairer to easily identify the fault type. In addition, it is not necessary to separately provide a telephone for fault reporting, and the maintenance cost of the apparatus can be reduced.

Next, the latter user information disclosure page may be a web page that exposes public information set by the user. For example, as shown in FIG. 1I, the user information disclosure page may be a web page for a business card, an advertisement flyer contact disclosure, or a shop guide. Therefore, in the present invention, only the online information needs to be changed at the time of changing the contact information such as the telephone number and the e-mail address, so that it is unnecessary to change and print the business card, flyer, and the like unnecessarily at the time of changing the contact information. In addition, according to the present invention, a specific menu can be selected on the user information disclosure page and can be easily switched to the user calling function, thereby eliminating the inconvenience of the user inputting the keypad for calling a subscriber.

Hereinafter, a user call support apparatus based on an identification code according to an embodiment of the present invention will be described with reference to FIGS. 2A and 2B. FIG. FIG. 2A is a configuration diagram illustrating a user call support apparatus based on an identification code according to an embodiment of the present invention, FIG. 2B is a diagram illustrating a hybrid connection method according to an embodiment of the present invention, FIG. FIG. 8 is a configuration diagram showing an exchange service providing unit according to the embodiment. FIG.

The storage unit 210 stores the identification codes of the at least one subscriber terminal subscribed to the call relay service, and the connection environment settings set by the contact and the subscriber, in correlation with each other.

Here, the identification code may be at least one of a one-dimensional bar code, a two-dimensional bar code, and a QR code. Alternatively, it may be another scanable identification code.

The storage unit 210 may further store other data for a subscriber call, a service subscription, an ID code generation, a user authentication, and a service bill settlement.

The identification code assigning unit 220 confirms the contact of the subscriber terminal to be used for the user call for the call relay service, if there is a terminal requesting subscription to the call relay service. The identification code assigning unit 220 generates an identification code to replace the user room contact and provides the identification code to the subscriber terminal 300 or another terminal.

In addition, the identification code assigning unit 220 may store the generated identification code in the storage unit 210 in association with the contact of the subscriber. Such an identification code may be exposed on behalf of the contact at the location where the contact is to be exposed.

At this time, the identification code assignment unit 220 can provide a call relay service subscription function through a predetermined web page or a predetermined specific application.

The app provider 250 may provide an app for subscription terminal subscription to subscription terminal 300 and may provide an app for call subscription service to caller terminal 100.

The connection environment setting unit 230 provides an interface for setting at least one of a connection using a telephone number, an application-based connection, a web page connection, and a hybrid connection to a subscriber. Then, the connection setting unit 230 associates the connection environment setting set by the subscriber with the contact information and the identification code of the subscriber, and stores the setting in the storage unit 210.

Here, the connection using the telephone number may be at least one of a telephone connection to a telephone number, which is a contact corresponding to the scanned identification code, and a character connection.

In addition, the app based connection may be at least one of an APP (APP) based VoIP call connection corresponding to the scanned identification code, an app based chat connection, and a callback phone connection.

The web page connection may be at least one of a user custom page corresponding to the identification code or a connection to the user's public information page.

In addition, the connection configuration unit 230 may further provide an interface for other settings such as a connectable time to the subscriber terminal and a retry count when the subscriber terminal fails to connect, in addition to the connection method between the caller terminal and the subscriber terminal. In addition, the connection setting unit 230 may store the setting set through the interface in the storage unit 210. [

The exchange service provider 240 relays that the caller terminal 100 calls a subscriber terminal of one subscriber when the caller terminal 100 that has scanned the exposed identification code requests a subscriber call corresponding to the identification code .

Specifically, when a subscriber call corresponding to an identification code is requested from the caller terminal 100, the exchange service provider 240 confirms the connection setting of the subscriber corresponding to one identification code from the storage unit 210 do. Here, the contact may be at least one of a telephone number of the subscriber terminal, an app connection address installed in the subscriber terminal, and a web page address (e.g., URI: Uniform Resource Indicator) set by the subscriber.

Then, the exchange service provider 240 relays the call of one subscriber terminal in at least one of a connection using a telephone number, an application-based connection, a web page connection, and a hybrid connection according to the connection setting of the identified subscriber. Hereinafter, a call relay service for each connection mode by the exchange service provider 240 will be described.

First, in the case of relaying one subscriber call using a connection method using a telephone number, the exchange service offerer 240 transmits a security connection call number (a security phone number) instead of a telephone number of a subscriber, To the caller terminal (100). When the exchange service provider 240 receives a general telephone connection request corresponding to the security phone number from the caller terminal 100, the exchange service provider 240 performs telephone connection or text transmission to one subscriber terminal. Accordingly, in the present invention, a call of the subscriber terminal 300 of the caller terminal 100 can be relayed to the caller terminal 100 without exposing the telephone number of the subscriber terminal.

At this time, the security telephone number may be a fixed telephone number for each subscriber, or a one-time telephone number.

When the security phone number is a fixed phone number, such as the former, the security phone number may be stored in the storage unit 210 in association with the contact of the subscriber.

On the other hand, when the security telephone number is a one-time telephone number, as in the latter case, the exchange service providing unit 240 generates a one-time telephone number when a call of one subscriber is requested from the caller terminal 100, (100). At this time, the exchange service providing unit 240 provides the call service of one subscriber using the one-time telephone number only for a predetermined period of time, and when the predetermined time expires, the subscriber's paging service using the one- May not be provided.

At this time, the exchange service providing unit 240 may perform at least one of voice call connection and text transfer using the telephone number.

Second, in the case of relaying one subscription call using the app-based connection scheme, the exchange service provider 240 transmits the subscription call to the caller terminal 100 using the predetermined application installed in the subscriber terminal 300 and the caller terminal 100, respectively. And relays subscriber terminal calls.

Specifically, when the caller terminal 100 requests a subscriber call corresponding to the scanned identification code, the exchange service provider 240 transmits the subscriber's security connection calling number corresponding to the scanned identification code to the caller terminal 100 ). Then, when the caller terminal 100 requests one subscriber call using the secure connection call number, the exchange service provider 240 performs a VoIP call, a chat connection, and a callback phone connection method between one subscriber terminal and the caller terminal 100 The subscriber's call can be relayed using a connection mode established by at least one of the subscribers.

At this time, the secure connection calling number may be a single use or a fixed value.

If the connection call number is one-time use, the exchange service providing unit 240 generates a secure connection call number every time a subscriber call corresponding to the scanned identification code is requested, and transmits the corresponding call number Can be destroyed. At this time, the exchange service providing unit 240 generates a secure connection call number using the available number band that is not currently being used for another subscriber call, and re-determines whether or not the secure connection call number is duplicated even after generation of the secure connection call number, It is possible to prevent errors due to duplication of call number.

When the secure connection calling number is a fixed value, the identification code assignment unit 220 or the exchange service providing unit 240 generates a fixed security connection calling number at the time of subscription of each subscriber or at the time of confirming a call request for each subscriber And may be stored in the storage unit 210 in association with the identification code or the contact information of each subscriber. In this case, the exchange service providing unit 240 can store a fixed value corresponding to an identification code of one subscriber in the storage unit 210, and relay the one subscriber call using the stored fixed value.

At this time, the secure connection calling number for the VoIP call may be in the form of a telephone number (E.164) or a URI.

For example, if the secure connection calling number for the VoIP connection is in the form of a telephone number and is one-time use, the caller terminal 100 scans the QR code with a predetermined calling relay service application and transmits a subscriber call corresponding to the scanned QR code . Then, the exchange service provider 240 generates a one-time secure connection call number 001-1234-1234 and provides it to the caller terminal 100. The calling terminal of the caller terminal 100 may attempt to make a call connection with the number 001-1234-1234 and then make a VoIP call with the subscriber terminal 300 through the relay of the exchange service provider 240. At this time, when the caller terminal 100 confirms the call connection attempt to the number 001-1234-1234 at the time when the caller terminal 100 exceeds the valid time (for example, 3 minutes) of the predetermined one-time secure connection call number, 240) can voicer the call connection is disabled. Specifically, the exchange service offerer 240 can provide voice guidance such as "Sorry, the connectable time has expired. Please rescan the QR code and try the subscriber call again ".

And the secure connection calling number for the app based chat connection may be an app chat connection address installed in one subscriber terminal. In this case, the exchange service provider 240 can support chatting using a communication protocol (XMPP, SIP, SOCKET, TCP Binary communication, etc.) for chat between the caller terminal 100 and the subscriber terminal 300 .

In addition, the secure connection calling number for the application-based callback telephone connection may be the unique URI of each subscriber terminal. In this case, the caller terminal 100 may scan the identification code through a predetermined application installed in the caller terminal 100, and then request a subscriber call by menu selection or the like. Then, the exchange service provider 240 may transmit a URI for a callback telephone connection of the subscriber terminal corresponding to the identification code. Then, the application of the caller terminal 100 requests a subscriber call corresponding to the received URI, and the exchange service provider 240 connects the telephone to the subscriber terminal corresponding to the URI. At this time, the exchange service providing unit 240 may provide an announcement to notify the subscriber terminal 300 that the subscriber call is requested. In addition, the exchange service provider 240 may also provide a callback telephone connection service by making a call to the caller terminal 100 and connecting the call between the subscriber terminal 300 and the caller terminal 100.

Thirdly, if the established connection method is a preset web page connection, the exchange service provider 240 can provide the web page pre-set by the subscriber to the caller terminal 100 by checking the scanned identification code.

Fourth, if the established connection scheme is a hybrid connection, the exchange service provider 240 checks whether the subscriber station 300 is in a web communication-enabled state. As a result of checking, if the subscriber terminal 300 is in a web communication enabled state, the exchange service provider 240 relays a call to the subscriber terminal 300 of the caller terminal 100 through the above-described application-based connection as shown in FIG. 2B . On the other hand, if the subscriber terminal 300 is in a state in which the web communication is not available, the exchange service provider 240 relays a call to the subscriber terminal 300 of the caller terminal 100 as a connection method using a telephone number, can do.

Meanwhile, in the above example, the exchange service provider 240 can retry communication for the number of retries according to the communication environment set by the user when a communication error occurs.

In addition, the exchange service providing unit 240 may provide the call relay service only for the connectable time according to the communication environment set by the user.

Hereinafter, each component of the exchange service provider 240 will be described with reference to FIG. 2C.

The switching service providing unit 240 includes a switch center core 241, a REST API unit 242, a web function unit 243, a VoIP soft switch 244, an IVR function unit 245, an SMS function unit 246, and an IM function 247. [

The switch center core 241 controls and controls the communication processing flow by linking each component for the call relay service with the internal API.

The REST API unit 242 provides various application program interfaces such as an API for a caller terminal, an API for a subscriber terminal, an internal API for connecting each component, a business entity interoperable API corresponding to each connection method, and a Web API.

The web function unit 243 provides various web pages (service subscription, connection environment setting, web page setting, etc.) for the call relay service to the user.

The VoIP soft switch 244 provides call routing in a VoIP Internet telephone network to support communication of a public telephone network (PSTN / ISDN-POTS) and interconnection of VoIP equipment. In other words, the VoIP soft switch 244 can perform an inbound call, an outbound call, a call routing, a call transfer, and the like.

The IVR (Interactive Voice Response) function unit 245 provides functions such as voice guidance, scenario setting, and authentication.

The SMS function unit 246 relays characters between the caller terminal 100 and the subscriber terminal 300 in cooperation with the mobile communication company and the SMSC (Short Message Service Center).

The IM (Instant Messaging) function unit 247 enables message chatting between the caller terminal 100 and the subscriber terminal 300 using the public Internet.

As described above, according to the present invention, the communication between the other party and the subscriber can be securely connected without exposing the personal information, so that the personal information can be effectively secured.

Hereinafter, a call relay service method will be described with reference to FIG. 3 is a diagram illustrating a call relay service method according to an embodiment of the present invention.

3, when the exchange service provider 240 receives a user call corresponding to the ID code scanned from the caller terminal 100 (YES in S310), the exchange service provider 240 responds to the identification code requested from the storage unit 210 At step S320, and retrieves at least one of the subscriber contact and the connection environment setting. At this time, the caller terminal 100 may scan the identification code exposed in an online site or an offline place with a predetermined application and request a user call. Here, the predetermined app may be a normal app that can only scan an identification code (e.g., a QR code). Alternatively, the preset application may be an application dedicated to the call support service.

The exchange service providing unit 240 checks the validity of the scanned identification code (S330). At this time, the exchange service provider 240 can check the contents (validation code, for example, Check SUM, etc.) included in the scanned identification code, and check the validity of the scanned identification code using the contents. Alternatively, the exchange service providing unit 240 may check that the scanned identification code is valid if there is a contact corresponding to the scanned identification code or a subscriber connection configuration.

If it is determined in step S330 that the scanned identification code is valid, the exchange service provider 240 determines whether the secure connection call number generation mode is one-time use (S340). At this time, the generation form of the call number may be set by the subscriber or the system administrator.

If the generation type of the calling number is one-time, the exchange service provider 240 generates a one-time secure connection calling number and confirms the stored effective time (S350).

On the other hand, if the generation type of the calling number is a fixed value, the switching service provider 240 loads the fixed security connection calling number from the storage unit 210 (S360).

Thereafter, the exchange service providing unit 240 transmits a subscriber call using at least one of a normal telephone connection, a general character transmission, an app-based telephone connection, an app-based connection, and a web page connection using a one- And provides a service (S370).

If it is determined in step S330 that the scanned identification code is not valid, the exchange service provider 240 notifies the error of the identification code to a message in step S380.

In addition, the exchange service provider 240 can guide the expiration of the valid time to voice or message when the subscriber call is requested after the valid time of the disposable call number expires.

On the other hand, the execution order of each step in the above-described example may be changed. For example, if the subscriber's contact or connection environment setting is unnecessary for the validation of the step S330, or if the validation code is used, the step S330 may be performed before the step S320.

Hereinafter, a subscriber calling method according to various embodiments of the present invention where the identification code is a QR code will be described with reference to FIGS. 4A to 4F. FIG.

4A is a diagram illustrating a subscriber calling method of a conventional telephone connection method according to an exemplary embodiment of the present invention.

The caller terminal 100 scans the QR code with a preset application (S411) and requests a secure connection call number corresponding to the QR code (S412). At this time, the caller terminal 100 can transmit the contents of the QR code through the predetermined application.

Then, the relay apparatus 200 confirms that the calling method of the subscriber corresponding to the contents of the QR code is the ordinary telephone connection from the storage unit 210, and confirms the security connection calling number for the general telephone connection (S413).

Subsequently, the relay apparatus 200 provides the secure connection calling number for the confirmed normal telephone connection to the caller terminal 100 (S414).

Then, in response to the caller's operation, the caller terminal 100 attempts to make a normal call using the secure connection call number (S415).

When the relay apparatus 200 confirms an attempt to make a telephone call using the secure connection call number of the caller terminal 100, the relay apparatus 200 performs validation of the general telephone call attempt and performs caller authentication (S416). For example, the relay apparatus 200 confirms whether the caller terminal 100 is a caller terminal 100 that has provided a secure connection call number by using a telephone number of the caller terminal 100, Can be performed. Alternatively, the relay apparatus 200 may verify the validity by checking whether a dialing attempt occurred within the validity time when the one-time secure connection calling number is used.

After validation and caller authentication, the relay apparatus 200 calls the subscriber terminal using the public telephone network (S417).

Then, under the relay of the relay apparatus 200, the caller terminal 100 is connected to the subscriber terminal 300 by voice call (S418).

FIG. 4B is a diagram illustrating a user calling method according to an embodiment of the present invention. The other user calling method including the character transmission method is at least partially the same as the general phone connection method of FIG. 4A, and therefore, the different steps will be described below.

4B, when the relay apparatus 200 receives the text message corresponding to the secure connection call number from the caller terminal 100 (S421), the relay apparatus 200 performs validation and caller authentication (S422).

Then, the relay apparatus 200 sends a text message from the caller terminal 100 to the subscriber terminal 300 (S423). At this time, the relay apparatus 200 does not directly expose the telephone number of the caller terminal 100 to the subscriber terminal 300, but only the virtual number for text transmission through the relay apparatus 200 is disclosed to the subscriber terminal 300 .

Subsequently, the subscriber terminal 300 transmits a character to be returned to the caller terminal 100 as a virtual number to the relay device 200 (S424).

Then, the relay apparatus 200 performs validation and authentication processing on the reply character (S425), and transmits the reply character to the caller terminal 100 (S426).

4C is a diagram illustrating an application-based VoIP call connection method according to an embodiment of the present invention.

When the subscriber call corresponding to the QR code is requested from the caller terminal 100, the relay device 200 transmits the telephone number type (E.164) corresponding to the QR code or the secure connection telephone number of the URI type (S431) .

Then, the caller terminal 100 requests a VoIP call using a secure connection telephone number in the form of a telephone number or a URI (S432).

Thereafter, the relay apparatus 200 notifies the subscriber terminal 300 that the QR code-based call is requested (S434) through validation and caller authentication (S433), and the subscriber terminal 300 accepts the call connection S435).

When the subscriber terminal 300 confirms the call connection acceptance, the relay apparatus 200 informs the caller terminal 100 of the call connection (S436), and transmits and receives RTP (Real Time Protocol) packets to relay the VoIP voice call S437). At this time, the relay apparatus 200 can relay the VoIP voice call by the VoIP soft switch 244.

FIG. 4D is a diagram illustrating an app-based chat connection method according to an embodiment of the present invention.

When the subscriber call corresponding to the QR code is requested from the caller terminal 100, the relay device 200 provides the chat connection (IM) connection address, which is a secure connection call number, to the caller terminal 100 (S441).
