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 the originating location register 39 to confirm whether the calling terminal 10 subscribes to its own authentication service. As the calling party location register 39 recognizes that the calling terminal 10 is subscribed to its own authentication service, the calling party location register 39 provides information about this to the calling party exchange 35 in step 330.

In step 340 to step 360, the calling side exchange 35 recognizes that the calling terminal 10 is subscribed to its own authentication service and provides the calling terminal information to the call authentication server 50 to provide authentication information of the calling terminal 10. Receive. Here, the calling terminal information is preset unique identification information (for example, a phone number, ID, serial number, etc.) that can be recognized by the call authentication server 50, and by using this, the call authentication server 50 uses the calling terminal. Extract authentication information corresponding to.

In step 370, 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 380, the called party location register 38 transmits a call connection path to the called terminal 70 to the calling party exchange 35. Here, the called party location register 38 inquires 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 390, the calling party exchanger 35 connects a call with the called party exchanger 36 corresponding to the call connection path to the called terminal 70 received from the called party location register 38, The authentication information is provided to the destination side exchange 36. 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 395, 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, the authentication information is provided together with an alert signal (a ringing tone is received at the called terminal), and the existing caller ID service (CNIP) or the caller provides real-time information or preset information. 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 authentication information from the source side exchange 35, may send an SMS to the destination terminal 70.

Accordingly, the receiving terminal 70 receiving the short message may access the authentication information page including the authentication information of the calling terminal 10 by using the same.

Referring to FIG. 4, a processing procedure according to the second of the three embodiments described above is described, in step 410, the calling terminal 10 requests a call connection for a voice call to the calling exchange 35 through a base station. do. 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 confirmation from the calling location register 39 whether the calling terminal 10 subscribes to its own authentication service.

In step 430 to step 450, the calling party location register 39 provides the calling terminal information to the call authentication server 50 as the calling terminal 10 recognizes that the calling terminal 10 is subscribed to its authentication service, thereby providing authentication information of the calling terminal 10. Is received from the call authentication server 50. In step 460, the originating location register 39 transmits authentication information of the calling terminal 10 to the calling exchange 35.

In step 480, the called party location register 38 transmits a call connection path to the called terminal 70 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 490, the calling side exchange 35 establishes a call with the called side exchange 36 through a call connection path, and includes the authentication information of the calling terminal 10 in the message transmitted when setting up the call. To provide. In step 495, 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.

Referring to FIG. 5, the processing procedure according to the third of the three embodiments described above is described in step 510, the originating exchange 35 receives a call connection request from the originating terminal 10, and in step 515. The originating location register 39 requests to confirm whether the originating terminal 10 subscribes to its own authentication service.

In step 520 to step 525, the calling party location register 39 recognizes that the calling terminal 10 subscribes to its own authentication service, and recognizes that the own authentication service is an intelligent network service. Information recognizable by 35) is transmitted to the source exchange 35.

In step 530, the exchange provides the intelligent network exchange 40 with information for connection of the call (calling terminal information and called terminal information, including information on whether to subscribe to its own authentication service). In operation 535, the intelligent network switch 40 recognizes that the calling terminal 10 subscribes to its own 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 switch 40, and in step 550, the intelligent network switch 40 receives the received authentication information. The transmitted authentication information to the IP 42 in the intelligent network system, and in step 555, the IP 42 stores it. Here, the authentication information may be received in the form of a voice file from the call authentication server 50, and when received in a text format, is converted into a voice form using a text-to-speech (TTS) technique at the IP 42. It may be stored or converted in real time when it is provided to the called terminal 70.

In step 560, the intelligent network exchange 40 establishes a call with the called side exchange 36. Here, the call connection information for call setup can be received by the intelligent network switch 40 itself from the called party location register (38).

In step 565, the IP 42 provides the authentication information to the called terminal 70 through a set call or a separate call.

Here, when the user of the destination terminal 70 receives a call in a manner in which the IP 42 provides authentication information to the destination terminal 70, the intelligent network switch 40 connects the IP 42 and the destination terminal 70 to make an outgoing call. Authentication information of the terminal 10 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 40 connects with the IP 42 to provide authentication information to the terminating terminal 70 by voice and to the user's selection of the terminating terminal 70. Accordingly, the call between the calling terminal 10 and the called terminal 70 is connected. For example, the call terminal may be connected only when the user presses a preset button (for example, a * button) of the called terminal 70. That is, the intelligent network switch 40 connects a call between the calling terminal 10 and the called terminal 70 as it receives a message transmitted from the called terminal 70 according to the call connection selection. 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 40 connects a call between the calling terminal 10 and the called terminal 70 via the IP 42. Therefore, the authentication information in the form of voice and voice information of the user of the calling terminal 10 may be synthesized and provided in the call path delivered from the IP 42 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.

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.

FIG. 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 makes a call together with authentication information that the calling terminal 10 is an AAA bank representative.

Here, if the location registered by the user of the calling terminal 10 as a work location and the current location of the calling terminal 10 are different from each other by using the location information of the calling terminal 10, the self authentication service may not be provided. 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 the current call terminal from the telephone network 30 or the location information providing server which acquired the position information of the call terminal 10. The location information of 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, "[KTF authentication information]" indicating that the authentication information as shown in Figures 6 and 7 is a service through which the user of the calling terminal 10 provides information input or preset by the caller such as SMS or CNAP. It is desirable to be limited to citations.
