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 associated with the call authentication server 50 to provide a service (hereinafter referred to as "party authentication service") that provides the other party's authentication information when the call is connected according to the present invention, the other party's authentication service subscribed to The terminal acquires the other party's authentication information from the call authentication server 50 and provides the terminal with the other party's authentication service subscription. That is, when the calling terminal 10 is subscribed to the other party's authentication service, it provides the calling terminal 10 with authentication information of the called terminal 70 (only possible when registered in the other party's authentication service). If the other party subscribes to the authentication service, the authentication information of the calling terminal 10 is provided to the called terminal 70.

The call authentication server 50 performs a function of providing the telephone network 30 with authentication information of a terminal (including the called terminal 70 and the calling terminal 10) subscribed to the service to provide the counterpart authentication service. Therefore, the telephone network 30 provides the authentication information received from the call authentication server 50 to the calling terminal 10 or the called terminal 70 when the voice call is connected.

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 counterpart 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 counterpart authentication service 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 exchangers 35 and 36, the location register 37, the intelligent network switch 39, and call authentication. The server 50 and the called terminal 70 are 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. In addition to the above-described location register 37, it is obvious that all devices for storing the subscriber authentication service subscriber information according to the present invention can be equally applied.

Typically, the location register 37 stores not only the counterpart authentication service according to the present invention, but also information on other subscribed services. It is determined whether to subscribe to a specific service through the information received from the originating terminal 10 via the exchanges 35 and 36 (information on the originating terminal 10 and / or information on the called terminal 70), and the subscribed service. If present, information corresponding to the service is provided to the exchanges 35 and 36.

The location register 37 stores subscription information of the counterpart authentication service according to the present invention of the associated terminal, and provides the information to the switches 35 and 36 or the intelligent network switch 39, or with the call authentication server 50. In association with the authentication information may be provided to the exchange (35, 36).

Hereinafter, a location register corresponding to the calling terminal 10 will be referred to as a calling party location register, and a location register corresponding to the called terminal 70 will be referred to as a called party location register. Of course, the information of the calling terminal 10 and the called terminal 70 can be stored and managed in one location register.

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. (70) The information (exchanged exchange and route information, etc.) is acquired to establish a call with the exchange 36 on the called side. Here, the switch 35 receives the service subscription information of the called terminal 70 from the called party location register. That is, the exchange may receive the other party's authentication service subscription or authentication information of the calling terminal 10 (when the location register is directly linked with the call authentication server 50) from the called party's 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 can receive the other party's authentication service subscription or authentication information of the called terminal 70 (when the location register works with the direct call authentication server 50) from the calling location register.

Hereinafter, the exchange receiving the call request from the originating terminal 10 will be referred to as the called side exchange 36, 36 which is connected through the originating exchange 35, the called terminal 70 and the base station 22. do. 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.

The intelligent network switch 39 is a switch located in the intelligent network. Recently used intelligent network is a network that connects a computer to a communication network to enable easy adoption of new technologies. Therefore, the intelligent network switch 39 performs the function of providing the counterpart's authentication information to the terminal subscribed to the service in cooperation with the call authentication server 50 to provide the counterpart authentication service according to the present invention. In particular, the intelligent network switch 39 may provide the other party's authentication information to the terminal in various forms such as voice using IP (Intelligent Peripheral) (not shown) in the intelligent network system, which is a device for providing a resource such as voice.

Hereinafter, a process of providing the counterpart authentication service in cooperation with the call authentication server 50 in the mobile communication network will be described in detail.

The process of providing the counterpart authentication service in the mobile communication network may include the following three embodiments. First, the location register 37 determines whether to subscribe to the other party's authentication service, and provides the service subscription to the exchange 35 so that the exchange 35 interoperates with the call authentication server 50 and the corresponding authentication information (the other party authentication). Authentication information of the other party of the terminal subscribed to the service) may be provided to the terminal subscribed to the other party's authentication service.

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.

The third is to set the counterpart authentication service as an intelligent network service. That is, as the location register 37 recognizes that the called terminal 70 or the calling terminal 10 is subscribed to the other party's authentication service, the relevant information for providing the other party's authentication service (called terminal 70 information, the calling terminal ( 10) information and service subscription information) is provided to the intelligent network exchanger 39 via the exchanger 35, and the intelligent network exchanger 39 cooperates with the call authentication server 50 to obtain authentication information for the call counterpart and correspondingly. It can be provided to the terminal.

Hereinafter, a case in which the called terminal 70 is subscribed to the counterpart authentication service will be described with reference to the related drawings.

3 to 5 are diagrams illustrating a process of providing a counterpart authentication service according to each preferred embodiment of the present invention.

Referring to FIG. 3, a processing procedure according to the first of the three embodiments described above is described, in step 310, the calling terminal 10 connects a call for a voice call to the calling exchange 35 through the base station 21. Ask. Here, the calling terminal 10 transmits the telephone number of the called terminal 70 to the calling side exchange 35.

In step 320, 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 330, the called party location register 38 transmits the call connection path of the called terminal 70 and the counterpart authentication service subscription information to the calling party exchange 35. Here, the called party location register 38 inquires of the route to the called party exchange 36, receives the call connection path from the called party exchange 36, and provides it to the calling party exchange 35.

In step 340, as the calling party exchange 35 recognizes that the called terminal 70 is subscribed to the counterpart authentication service, in step 350, the calling exchange server 35 provides the calling terminal 10 information to the call authentication server 50 of the calling terminal 10. Request authentication information. Here, the calling terminal 10 information is preset unique identification information (for example, phone number, ID, serial number, etc.) that can be recognized by the call authentication server 50.

In step 360, the call authentication server 50 extracts authentication information of the calling terminal 10 and provides the calling exchanger 35 to the calling exchange. Here, since the call authentication server 50 does not store the authentication information of all the calling terminals 10, the call authentication server 50 searches for the authentication information of the calling terminal 10 to determine whether it exists, and if it does not exist, The message can be sent to the exchange.

In step 370, the calling side exchange 35 connects the call with the called side exchange 36 corresponding to the call connection path received from the called side location register 38 to the called terminal 70. Here, the originating exchange 35 transmits the authentication message of the originating terminal 10 to the signal message transmitted to the called exchange 36.

In operation 380, the called party exchanger 36 may output the authentication information of the calling terminal 10 to the display device of the called terminal 70 in the process of establishing a call with the called terminal 70. That is, by providing authentication information together with an alert signal (a ringer is received on the receiving terminal), an existing caller ID service (CNIP) or a caller provides real-time input or preset specific information. It may be processed in the same or similar process as the service (CNAP). Since this will be apparent to those skilled in the art, a detailed description thereof will be omitted.

Here, the source exchanger 35 receives the connection information such as URL (URL) that can access the authentication information page of the calling terminal 10 as the authentication information received from the call authentication server 50, and the called terminal 70. Short message service (SMS) can be sent by linking access information with SMSC. Of course, the authentication information may be transmitted in the form of a short message. It may be sent before or after the call connection, or may be sent in synchronization with the call connection.

In the case of a terminal capable of Simultaneous Voice & Data (SVD) service, a message such as an SMS can be received even in a call state, and the detailed authentication information of the call counterpart can be queried by using the same.

 Here, the SMSC and the SMS is an embodiment, and it is obvious that the long message (LMS, Long Message Service, LMSC provided) and the multimedia message (MMS, Multimedia Message Service, MMSC provided) may be equally applied.

Similarly, it is natural that the destination side exchange 36, which receives the authentication information from the source side exchange 35, can send an SMS to the destination terminal 70.

Therefore, the receiving terminal 70 receiving the short message may access the authentication information page provided by the call authentication server 50 by using the same.

Referring to FIG. 4, the processing procedure according to the second of the three embodiments described above, in step 410, the calling terminal 10 requests a call connection for a voice call through the base station to the calling exchange 35. . Here, the calling terminal 10 transmits the telephone number of the called terminal 70 to the calling side exchange 35.

In step 420, the calling side exchange 35 requests a call connection path to the called terminal 70 to the called side location register 38. In step 430, the called party location register 38 recognizes that the called terminal 70 is subscribed to the counterpart authentication service, and in step 440, requests for authentication information of the calling terminal 10 to the call authentication server 50. Here, the called party location register 38 receives the information of the calling terminal 10 from the calling exchange 35 and transmits the information of the calling terminal 10 to the call authentication server 50, thereby making the calling terminal 10 possible. Authentication information corresponding to the information may be received from the call authentication server 50.

In step 450, the called party location register 38, which has received the authentication information of the calling terminal 10 from the call authentication server 50, authenticates the call connection path to the called terminal 70 and the calling terminal 10 in step 460. The information is sent to the originating exchange 35.

In step 470, the calling side exchange 35 establishes a call with the called side exchange 36, and provides the called side exchange 36 with the authentication information of the calling terminal 10 in the message transmitted when setting up the call. In step 480, the called party exchanger 36 provides authentication information of the calling terminal 10 to the called terminal 70 in the call setup process.

As another embodiment, as described above, instead of providing the authentication information directly to the destination terminal 70, the connection information for accessing the authentication information page using the SMS may be provided to the destination terminal 70. The call authentication server 50 may directly transmit the short message including the access information to the called terminal 70 in association with the SMSC. That is, when the call authentication server 50 receives the request for authentication information from the called party location register 38, the call authentication server 50 may immediately send a short message including the access information to the called terminal 70 in synchronization with the call connection.

The processing procedure according to the third of the three embodiments described above is described with reference to FIG. 5. In step 510, the calling side exchange 35 receives a call connection request from the calling terminal 10, and in step 515 the called party. A call connection path is requested to the destination terminal 70 for call connection to the location register 38.

In step 520, the called party location register 38 recognizes that the called terminal 70 is subscribed to the other party's authentication service, recognizes that the other party's authentication service is an intelligent network service, and in step 525, the exchange may recognize the corresponding information (the intelligent network service). Information and call connection paths to the called terminal 70) are provided to the exchange.

In step 530, the exchange provides the intelligent network switch 39 with information for connection of the call (receipt terminal 70 information including call partner information subscription information, call connection path, originating terminal 10 information, etc.). In operation 535, the intelligent network switch 39 recognizes that the called terminal 70 is subscribed to the counterpart authentication service, and requests the call authentication server 50 for authentication information of the calling terminal 10.

In step 540, the call authentication server 50 retrieves the corresponding authentication information, and transmits the authentication information of the originating terminal 10 extracted in step 545 to the intelligent network exchange 39, and in step 550 the intelligent network exchange 39 receives The transmitted authentication information to an IP in the intelligent network system, and the IP stores the stored authentication information in step 555. Here, the authentication information may be received in the form of a voice file from the call authentication server 50, and when received in text format, is converted into a voice form using TTS (Text-To-Speech) technology and stored in IP or stored. It may be converted in real time when it is provided to the called terminal 70.

In step 560, the intelligent network switch 39 establishes a call with the called side switch 36 using the call connection path to the called terminal 70.

In step 565, the IP provides authentication information to the called terminal 70 through a set call or a separate call.

Here, when the user of the terminal 70 receives a call in a manner in which the IP provides authentication information to the destination terminal 70, the intelligent network switch 39 connects the IP with the destination terminal 70 to authenticate the originating terminal 10. Information may be provided to the called terminal 70 by voice, and then a call between the calling terminal 10 and the called terminal 70 may be connected.

Alternatively, when the user of the terminating terminal 70 receives a call, the intelligent network switch 39 connects with the IP to provide authentication information to the terminating terminal 70 by voice, and according to the selection of the terminating terminal 70 user, the originating terminal. The call between the 10 and the called terminal 70 is connected. For example, the user can make a call only when the user of the called terminal 70 presses a preset button (for example, a call button) of the called terminal 70. That is, the intelligent network switch 39 connects a call between the calling terminal 10 and the called terminal 70 as it receives a message transmitted according to the call connection selection from the called terminal 70. Accordingly, the user of the called terminal 70 may determine whether to connect the call after checking the authentication information of the calling terminal 10.

In another method, when the user of the called terminal 70 receives a call, the intelligent network switch 39 connects a call between the calling terminal 10 and the called terminal 70 via IP. Therefore, the authentication information in the form of voice and voice information of the user of the originating terminal 10 may be synthesized and provided on the call path delivered from the IP to the called terminal 70.

When providing authentication information according to the above-described three embodiments, the authentication information using the location information of the originating terminal 10 may be provided. Hereinafter, an embodiment of this and an embodiment of an authentication information providing screen in a terminal according to providing authentication information will be described with reference to related drawings.

6A and 6B are diagrams illustrating an example displayed on a terminal provided with a counterpart authentication service according to an exemplary embodiment of the present invention.

6A and 6B, when the calling terminal 10 is a phone of an AAAA bank or a mobile terminal of an employee of an AAAA bank, authentication information of the calling terminal 10 displayed on the called terminal 70 is respectively obtained. Is shown.

6A is an exemplary screen of the called terminal 70 when the calling terminal 10 is a telephone.

Example screen 610 is provided with only the authentication information for the other party name, example screen 630 is the content of the business unit according to the phone number is included in the authentication information when the individual business department is registered in the call authentication server 50 Can be provided together. 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.

6B is an exemplary screen of the 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 670 or the example screen 690 may provide the calling terminal 10 with the authentication information of the AAAA bank clerk together with information on the location of the call.

Here, the counterpart authentication service may not be provided when the location registered by the calling terminal 10 user as a working place and the current location of the calling terminal 10 user are different from each other by using the location information of the calling terminal 10 user. . 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 location information set to correspond to the authentication information of the terminal, and is currently calling terminal 10 from the exchange (or location register) that has acquired the location information of the calling terminal 10. Receive location information and compare it with 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.

6A and 6B, "[KTF authentication information]", which indicates authentication information, is a service provided by a caller terminal 10 that provides information input or preset by a caller such as SMS or CNAP. It is desirable to be limited to citations.

Although the above-described counterpart authentication service has been described as an example of providing authentication information of the calling terminal 10 to the called terminal 70, even when the calling terminal 10 is subscribed to the counterpart authentication service, authentication of the called terminal 70 is performed. Information may be provided to the calling terminal 10. For example, when a user who subscribes to the other party's authentication service does not receive a call to a specific number, when the user calls the specific number, the other party's authentication information may be provided.

The procedure of receiving authentication information of the called terminal 70 may also be performed in the same or similar manner to each of the above-described embodiments. That is, as the calling party location register recognizes the other party's authentication service subscription of the calling terminal 10, the calling party location register 35 provides information about the calling party switching server 35 or the intelligent network switch 39, or the calling party location register itself. In connection with 50, authentication information may be provided. This will be apparent to those skilled in the art through the above description, so a detailed description will be omitted.

However, the caller terminal 10 cannot provide authentication information in the form of CNIP, CNAP, etc. to the caller terminal 10 as described above, and thus, the caller terminal 70 may be provided in a manner similar to a service for providing a ringback tone service through multimedia such as music contents. ) May be provided in the form of voice, text, or image. Therefore, the calling terminal 10 may be provided with authentication information through the screen and / or speaker during the call connection. Since the multimedia ringback tone service is still provided to the person skilled in the art, a detailed description of the service providing procedure will be omitted.
