Hereinafter, a method for providing a caller authentication service according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram showing an overall system for providing authentication information of a call originator according to an exemplary embodiment of the present invention.

According to FIG. 1, the entire system includes a calling terminal 10, a called terminal 70, a telephone network 30, and a call authentication server 50.

The calling terminal 10 and the called terminal 70 are wireless LANs as well as general wired terminals such as mobile communication terminals and telephones, including PCS, PDA, smart phones, etc., which can make voice calls through mobile and wired telephone networks. ) Refers to all terminals capable of making a voice call through the Internet because the terminal, a Bluetooth terminal, and a portable Internet terminal can access the Internet. Hereinafter, a mobile communication terminal will be described as an example, but as described above, all terminals capable of a voice call can be applied in the same manner.

The telephone network 30 includes both a mobile communication network and a wired telephone network provided through a telephone station, and performs a function of setting a channel for a voice call between the calling terminal 10 and the called terminal 70. Hereinafter, for convenience of description, a mobile communication network will be described as an example, but it will be apparent to those skilled in the art that a wired telephone network including a wired switch may be applied in the same or similar manner.

The telephone network 30 is a call authentication server 50 to provide a service (hereinafter referred to as "caller authentication service") that provides the caller's authentication information (that is, the authentication information of the calling terminal) when the call is connected according to the present invention. In connection with the receiving terminal 970, the authentication information of the calling terminal 10 is obtained from the call authentication server 50 and provided to the called terminal 70. Here, the caller authentication service is provided when the calling terminal 10 subscribes to its own authentication service or the called terminal 70 subscribes to the other party's authentication service. That is, when the calling terminal 10 subscribes to its own authentication service, it is to provide authentication information of its own (that is, the caller) to the called terminal 70 according to a phone call, and the called terminal 70 subscribes to the other party's authentication service. In the case of receiving a phone call, authentication information of the other party (sender) is received. Hereinafter, the self-authentication service that the calling terminal 10 provides its own authentication information when making a phone call, and receiving the caller's authentication information by the called terminal 70 will be referred to as a counterpart authentication service. This is called caller authentication service.

 In particular, the telephone network 30 provides authentication information of the calling terminal 10 to the called terminal 70 to which the call is not connected as a short message service (SMS), a multimedia message service (MMS), or the like. The authentication information page for verifying the authentication information or authentication information of the calling terminal 10 calling the called terminal 70 in a situation where the telephone call cannot be connected, such as being located in an area where the power is turned off or the coverage right has been removed. When the destination terminal 70 is able to receive the URL of the server located is transmitted via SMS, MMS, and the like. Therefore, the called terminal user can acquire reliable authentication information of the calling party to which the call is not connected. Here, in providing the authentication information to the destination terminal 70, when a unique IP is assigned to the destination terminal 70 in addition to SMS and MMS, the call authentication server 50 directly receives the data to the destination terminal and the corresponding authentication information. Of course, it may be provided that, it will be apparent that all means capable of transmitting other authentication information to the destination terminal 70 can be equally applied.

In the following, in providing caller authentication information according to the present invention, it will be described mainly to provide the authentication information of the calling terminal 10 according to the call not connected to the called terminal 70 in the future.

The call authentication server 50 performs a function of providing the telephone network 30 with authentication information of the calling terminal 10 in response to a request of the telephone network 30 to provide a caller authentication service. Thus, the telephone network 30 provides the authentication information received from the call authentication server 50 to the called terminal 70.

In addition, the call authentication server 50 stores the history information on the call request from the calling terminal 10 to correspond to the called terminal information (for example, a phone number) corresponding to the disconnected call. The call request history information stores a telephone number of the calling terminal 10, a call attempt time, location information of the calling terminal 10 at the time of a call attempt, and the like. Accordingly, when the called terminal 70 becomes available for call connection, such as when the power of the corresponding called terminal 70 corresponding to the call request history information is turned on again or located in a callable area, the call is made according to the stored call request history information. The authentication information of the terminal 10 is provided to the called terminal 70 in association with the telephone network 30.

The call authentication server 50 receives and stores data on information desired to be authenticated from a public institution, a financial institution, or a company or individual who wants to be authenticated publicly during a voice call. The above-mentioned data may be issued from an authentication information issuing authority (not shown) that provides public authentication information, such as the IRS, and may be received by the call authentication server 50 as an electronic document through the Internet.

Therefore, the call authentication server 50 stores the serial number (for example, the terminal phone number) and the corresponding authentication information, which is preset unique information, and requests authentication information including a specific serial number from the telephone network 30. Upon receiving the corresponding authentication information is provided to the telephone network 30.

Hereinafter, a configuration and procedure for providing a caller authentication service according to the present invention in a mobile communication network will be described.

2 is a block diagram schematically illustrating an entire system for providing a caller authentication service according to an unconnected call in a mobile communication network according to an exemplary embodiment of the present invention.

According to FIG. 2, the entire system includes the originating terminal 10, the base stations 31 and 32, the base station controllers 33 and 34, the exchanges 35 and 36, the location register 37, the call authentication server 50 and the incoming call. Terminal 70 is included.

The base stations 31 and 32 and the base station controllers 33 and 34 perform a relay function for communication between each terminal and the exchanges 30 and 35. Since the base stations 31 and 32 and the base station controllers 33 and 34 are obvious to those skilled in the art, detailed descriptions thereof will be omitted.

The location register 37 performs a function of storing information of the subscribed terminal. The location register 37 includes a home location register (HLR) and a visit location register (VLR), and the location register 37 includes information on subscribed service information of a connected terminal and a call connection location. Information is stored. The location register also stores terminal state information on whether the associated terminal is powered on or off. That is, the terminal state information is received and managed from the base station communicating with the terminal from time to time.

Typically, the location register 37 stores information about caller authentication services, as well as other subscribed services, in accordance with the present invention. It is determined whether to subscribe to a specific service through the information (calling terminal information and / or called terminal information) received from the calling terminal 10 via the exchange 35 and 36, and if there is a subscribed service, Corresponding information is provided to the exchanges 35 and 36.

The location register 37 stores the subscription information of the caller authentication service according to the present invention of the associated terminal, and provides the information to the switch 35, 36 or the intelligent network switch 39, or the call authentication server 50. In conjunction with the authentication information may be provided to the exchange (35, 36). Here, in addition to the above-described location register 37, it is obvious that all devices for storing the caller authentication service subscriber information according to the present invention can be equally applied.

Hereinafter, a location register that manages information of the called terminal 70 will be referred to as a called party location register, and a location register that manages information of the calling terminal 10 will be referred to as a calling party location register. Of course, it is also possible that one location register may manage the information of the calling terminal 10 and the called terminal 70.

The exchanges 35 and 36 perform a function of setting up a voice call between the calling terminal 10 and the called terminal 70. Typically, the exchange 35 of the calling party receives the information (for example, a phone number) of the called terminal 70 from the calling terminal 10, and the called terminal from the called party location register corresponding to the received phone number. Information (exchanged exchange and route information, etc.) is acquired to establish a call with the exchange 36 on the called party. Here, the exchange 35 of the calling party receives the service subscription information of the called terminal 70 from the called party location register. That is, the exchange 35 may receive the other party's authentication service subscription or the authentication information of the originating terminal 10 (when the location register interworks with the call authentication server 50 directly) from the called party location register. The exchange 35 also receives service subscription information of the calling terminal 10 from the calling location register. That is, the exchange 35 may receive from the originating location register whether or not it subscribes to its own authentication service or authentication information of the originating terminal 70 (when the location register interworks with the direct call authentication server 50).

Hereinafter, the exchange receiving the call request from the originating terminal 10 will be referred to as the called side exchange 36, the exchanger connected through the source-side exchanger 35, the destination terminal 70 and the base station 22. Of course, when the originating terminal 10 and the terminating terminal 70 are located in one exchange processing area, it is natural that one exchange performs the functions of the originating exchange 35 and the destination exchange 36.

Here, the entire system may further include a location information providing server (not shown) for providing location information of the terminal. The location information providing server may acquire the location information of the corresponding terminal by a cell method using a base station. In addition, it is obvious that the presently developed and used method or the location information acquisition method to be developed in the future may be applied in the same manner. The technology provided will be apparent to those skilled in the art, so detailed description thereof will be omitted. The location information providing server may directly provide the acquired location information of the terminal to the call authentication server 50, or may be provided through the exchange 35 or the location register 37. Here, in providing the location information to the call authentication server 50, location coordinates such as latitude and longitude may be provided, but may be converted into simplified information in a manner such as "Gangnam Station Crossroad" and provided.

Hereinafter, a process of providing authentication information of a caller who is not connected in connection with the call authentication server 50 in the mobile communication network will be described in detail.

A process of providing caller authentication information in a mobile communication network may include the following two embodiments. First, the location register 37 determines whether the caller authentication service is subscribed, and provides the service subscription to the switch 35 so that the switch 35 interworks with the call authentication server 50 in the caller terminal 10. It is to provide the authentication information of the destination terminal 70.

Secondly, the location register 37 may acquire the corresponding authentication information in association with the direct call authentication server 50 and provide the same to the exchange 35.

In addition, a process for providing caller authentication information in the mobile communication network according to the above-described embodiments is performed when the called terminal 10 is subscribed to the other party's authentication service and when the calling terminal 10 is subscribed to its own authentication service. Each may be performed differently.

Hereinafter, a processing procedure according to each of the above-described embodiments will be described with reference to related drawings.

3 to 5 are diagrams illustrating a process of providing authentication information of an unconnected call originator according to each preferred embodiment of the present invention.

Here, a case where the power of the terminating terminal 70 is turned off for the reason that the call is not connected will be described as an example. Even if the connection is not the same can be applied through the following description will be apparent.

The processing procedure according to the first embodiment of the above two embodiments will be described, but FIG. 3 shows a process of providing a caller authentication service according to the counterpart authentication service of the called terminal 70, and FIG. 10 is a diagram illustrating a process of providing a caller authentication service according to the self authentication service of FIG.

Referring to FIG. 3, in step 310, the calling terminal 10 requests a call connection for a voice call to the calling exchange 35 through the base station 31. Here, the calling terminal 10 transmits the telephone number of the called terminal 70 to the calling side exchange 35.

In step 315, the calling side exchange 35 requests a call connection path to the called terminal 70 for call connection to the called side location register 38. In step 320, the called party location register 38 confirms that the called terminal 70 is powered off. Also, it confirms that the called terminal 70 is subscribed to the counterpart authentication service, and transmits the called terminal status information and the counterpart authentication service subscription information to the calling side exchange 35 in step 325.

In step 330, the calling party exchanger 35 is not connected to the call because the called terminal 70 is currently powered off, and the caller authentication service according to the subscription of the other party's authentication service of the called terminal 70 should be provided. Upon recognizing, information about the disconnected call is transmitted to the call authentication server 50.

In operation 335, the call authentication server 50 stores call request history information corresponding to the call request of the calling terminal 10. That is, call request history information including caller terminal information and call request time information is stored so as to correspond to the called terminal information. The call request history information may include location information at the time of the call request of the calling terminal 10. The location information of the originating terminal 10 may be directly received from the originating terminal 10 having a location measuring means such as a GPS receiver, or measured using a cell measurement method of the base station 31 from a location information providing server. One location information may be received.

Thereafter, when the terminating terminal 70 is powered on in steps 340 to 350, a signal corresponding thereto is transmitted to the called party location register 38. The called party location register 38 changes the state information of the called terminal 70.

In step 355, the called party location register 38 informs the call authentication server 50 that the called terminal 70 is in a callable state. In this case, the called party location register 38 receives the corresponding information through the service subscription information of the called terminal only when the terminal that needs to provide the caller authentication service (that is, when the called terminal 70 is subscribed to the counterpart authentication service). Provided to the call authentication server 50. In another embodiment, the location register 37 may inform the call authentication server 50 of information about all terminals that change from the non-call state to the available state.

In step 360, the call authentication server 50 extracts the stored call request history information corresponding to the called terminal information, and extracts the authentication information for the calling terminal 10 corresponding to the call request history information. For example, the transmission time, the location information of the calling terminal 10, etc.) are transmitted to the called terminal 70. Here, the authentication information and the call request history may be transmitted to the SMS or the MMS through a Short Message Service Center (SMSC) (not shown) or a Multimedia Message Service Center (MMSC) (not shown) of the telephone network 30. If the unique IP is assigned to the call 70, the call authentication server 50 may be sent directly to the called terminal 70 as a data call.

In another embodiment, a procedure for providing a caller authentication service according to the self-authentication service subscription of the calling terminal 10 will be described with reference to FIG. 4. In step 410, the calling side exchange 35 transmits a base station from the calling terminal 10 to the base station. Receive a call connection request for a voice call over 31.

In steps 415 to 425, the calling party location register 39 transmits its own authentication service subscription information according to the request of the subscription information for the additional service subscribed to by the calling terminal 10 received from the calling party switching device 35 ( 35).

In step 430, the calling side exchange 35 requests a call connection path to the called terminal 70 for call connection to the called side location register 38. In step 435 to step 440, the called party location register 38 confirms that the called terminal 70 is powered off, and transmits the information to the calling party exchange 35.

In step 445, the calling side exchange 35 does not have a call connection because the called terminal 70 is currently turned off, and it is necessary to provide a caller authentication service according to the self-authentication service subscription of the calling terminal 70. Upon recognizing, information about the disconnected call is transmitted to the call authentication server 50. Here, although not shown in the figure, the calling side exchange 35 notifies the calling terminal 10 that the call is not connected. In addition, according to the selection of the calling terminal 10 notified that the call is not connected, it may be determined whether to provide the call request details including the authentication information of the calling terminal 10 to the called terminal 70. That is, the originating terminal 10 subscribed to the self-authentication service may determine whether to provide its own authentication information for the call that is not connected to the call.

In operation 450, the call authentication server 50 stores call request history information corresponding to the call request of the calling terminal 10. In addition, the step 455 call authentication server 50 then provides the called terminal 70 with a call request history including the authentication information of the calling terminal 10, when the called terminal 70 becomes available to call; The receiver terminal information is transmitted to the called party location register 38 so as to receive the information. In step 460, the called party location register 38 stores the received called terminal information so that the called terminal 70 can provide the call authentication server 50 with information about the called terminal 70 when it becomes available. In this case, when the called party location register 38 informs the call authentication server 50 of information about all terminals that change from the non-call state to the call enabled state, the above-described steps 455 to 450 may be omitted.

Thereafter, when the terminating terminal 70 is powered on in steps 470 to 480, a corresponding signal is transmitted to the terminating location register 38. The called party location register 38 changes the state information of the called terminal 70.

In step 485, the called party location register 38 informs the call authentication server 50 that the called terminal 70 is in a state where a call is available.

In step 490, the call authentication server 50 extracts the stored call request history information corresponding to the called terminal information, and extracts the authentication information for the calling terminal 10 corresponding to the call request history information to receive the call together with the call request history. Transmission to the terminal 70.

Hereinafter, the processing procedure according to the second of the two embodiments described above will be described with reference to FIG. 5. In step 510, the calling terminal 10 transmits a voice call to the calling exchange 35 through the base station 31. Request a call connection. Here, the calling terminal 10 transmits the telephone number of the called terminal 70 to the calling side exchange 35.

In step 515, the calling side exchange 35 requests a call connection path to the called terminal 70 for call connection to the called side location register 38. In step 520, the called party location register 38 confirms that the called terminal 70 is powered off, and also confirms that the called terminal 70 is subscribed to the counterpart authentication service. Accordingly, in step 525, the called party location register 38 notifies the calling party switch 35 that the call with the called terminal 70 cannot be connected, and in step 530 according to the counterpart authentication service subscription of the called terminal 70. The call authentication server 50 transmits information on providing the other party's authentication information according to the call that is not connected. That is, the called party location register 38 is a call request history and the calling terminal authentication information according to the call request from the calling terminal 10 when the call authentication server 50 becomes available to the call terminal 70 in the future It transmits the relevant information so that it can be transmitted to the destination terminal (70). Here, although not shown in the figure, the calling side exchange 35 may notify the calling terminal 10 that the call is not connected. Of course, steps 525 and 530 may be reversed.

In operation 535, the call authentication server 50 stores call request history information corresponding to the call request of the calling terminal 10. Thereafter, steps 540 to 560 may be performed in the same manner as steps 340 to 360 of the embodiment of FIG. 3.

Here, when providing the authentication information according to the above-described embodiments, the authentication information using the location information of the calling terminal 10 may be provided. Hereinafter, an example of outputting a screen for providing authentication information in a terminal according to an embodiment thereof and providing authentication information will be described with reference to related drawings.

In addition, when the person in charge is registered in the call authentication server 50 as shown in the example screen 650, the information on the person in charge may be included in the authentication information.

7 is an exemplary screen of a called terminal 70 when the calling terminal 10 is a mobile communication terminal such as a PCS or a PDA. In this case, more various authentication information can be provided by combining with location information. The example screen 710 or the example screen 730 may provide information on a location where the calling terminal 10 has made a call along with authentication information that the calling terminal 10 is an AAA bank representative.

Here, the caller authentication service may not be provided when the location registered by the user of the calling terminal 10 as a working place is different from the current location of the calling terminal 10 using the location information of the calling terminal 10. This is because if you are in a place other than your work place, it is likely that the call is irrelevant to your work. As a processing method for this, the call authentication server 50 stores the position information set to correspond to the authentication information of the terminal, and obtains the position information of the originating terminal 10 from the switch 35 (or the position register 37). The location information of the current calling terminal 10 is received and compared with the previously stored location information. Therefore, the authentication information may be provided only when the current location of the calling terminal 10 is included in a predetermined range of preset location information so as to correspond to the authentication information.

Here, as shown in FIG. 6 and FIG. 7, "[KTF authentication information]", which is an authentication mark indicating authentication information, is limited such that the user of the calling terminal 10 cannot quote through SMS.

Referring to FIG. 8 as an embodiment for increasing the reliability of the authentication display, a user interface area which is a space other than a space for outputting a message on the terminal 10 as shown by reference numeral 810 or an area for displaying the terminal state may be set in advance. The authentication display 820 may be output. That is, the terminal 10 analyzes the header included in the call request history including the citation information, and if the authentication information header indicating the citation information is included, the terminal 10 displays a fixed area (user) while the call request history is displayed on the terminal. The authentication display 820 indicating that the authentication information is reliable in the interface area or the terminal status display area) may be output.

In another embodiment, the terminal may cause the lamp to emit light of a specific color upon receiving the authentication information header. That is, output according to the authentication information may be performed by using a terminal status display device such as a lamp or a speaker (specific sound). Therefore, it is possible to prevent the general user from quoting authentication information.
