The present invention relates to a system and method for providing a caller ID information service, and more particularly, to a system and method for providing a caller ID information service for providing a caller ID information service using a USSD in a network.

Recently, various additional services have been provided in addition to text message service and call service due to the development of mobile communication technology, and one of them has been provided with a caller identification information display service that exposes identification information of a calling terminal to a receiving terminal when a call is connected.

For example, the mobile communication subscriber subscribes to the caller identification information display service to set his own identification information in advance, and when the call is connected to the receiving terminal, the predetermined identification information is displayed on the receiving terminal instead of his terminal number.

However, the conventional caller identification information display service is limited in that the service is supported according to the network environment and the terminal of the carrier. In addition, when the calling terminal and the receiving terminal each use a different carrier, there is a problem that the caller identification information display service is not provided.

The present invention has been proposed to solve the above problems, and provides a system and method for providing a caller identification information display service for transmitting service subscriber information of a calling terminal in a USSD format when a call connection is requested from the calling terminal to a receiving terminal. It aims to do it.

In order to achieve the above object, the present invention provides a system for providing a caller ID display service using USSD in a network, the system comprising: a database storing identification information of a terminal subscribed to the caller ID display service; An identification information transmission server for calling the identification information stored in the database and transmitting the identification information stored in the database to the gateway when the calling terminal is subscribed to the caller identification information display service; And a gateway for transmitting the identification information received from the identification information transmission server to a receiving terminal in a USSD format.

The present invention also provides a method for providing a caller ID display service using USSD in a network, the method comprising: registering identification information from a terminal subscribed to a caller ID display service and storing the identification information in a database; When a call connection is requested from a calling terminal to a called terminal, checking whether the calling terminal is subscribed to the caller identification information display service; When the calling terminal is subscribed to the calling party identification information display service, calling the identification information of the calling terminal stored in the database; And transmitting the called-up identification information to the receiving terminal in USSD format.

According to the present invention, since the identification information of the calling terminal is transmitted to the receiving terminal by using the USSD in a network such as GSM, GPRS, EDGE, WCDMA (3G), HSPDA / LTE, a network of a communication company to which the calling terminal and the receiving terminal are subscribed.

Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art may easily implement the technical idea of the present invention.

As shown in FIG. 1, a system for providing a caller ID information service using Unstructured Supplementary Services Data (USSD) in a network according to an embodiment of the present invention may include a Lettering Delivery Server (LDS); ), A database server (DBS) 12 and a gateway 18.

Here, the network includes various networks except for CDMA. For example, the network may be Global System for Mobile Communication (GSM), GPRS, EDGE, WCDMA (3G), or HSPDA / LTE.

According to the caller identification information display service providing system 10 having such a configuration, the terminal 2 30 receives identification information of the terminal 1 20 when a call is connected between the terminal 1 20 and the terminal 2 30 using the USSD. Can be provided to

The database server 12 stores identification information of a terminal subscribed to the caller identification information display service. For example, the terminal number of the terminal subscribed to the service and the identification information set in the terminal may be mapped and stored.

Here, the terminal number is a unique number of the terminal, and may be, for example, an International Mobile Station Identity (IMSI) assigned to a USIM card or a Mobile Station International ISDN Number (MSISDN) assigned to a terminal. The identification information is information displayed on the screen of the receiving terminal when the call is connected, and can be directly set by the service subscriber.

The identification information may be a character type or a character type including an emoticon according to a form, and may be a nickname or advertisement information directly set by a service subscriber according to the type of information. In addition, according to the standard of the USSD protocol, identification information may be used as a multimedia type including a picture, a picture file, a video, and the like.

In addition, one piece of identification information may be set for each terminal or a plurality of pieces of identification information may be set. When a plurality of pieces of identification information are set for one terminal, the user may preset which of the pieces of identification information to display. Alternatively, different identification information may be set according to timing. For example, different identification information may be displayed before the call is connected, while the bell is ringing, and after the call is terminated. Of course, it is also possible to combine a plurality of identification information, or display a combination of the identification information and the terminal number.

The database server 12 may also store history, statistical information, identification information transmission result data, billing information data, and the like.

The identification information transmission server 11 calls the identification information of the terminal 1 20 stored in the database server 12 when a call is requested from the terminal 1 20 subscribed to the caller identification information display service to the terminal 2 30. To the gateway 18.

In this case, whether the terminal 1 (20) is subscribed to the service is confirmed by the home location register (50), and the mobile telephone exchange 40 requests that the terminal 1 (20) subscribed to the service connect to the terminal 2 (30). The identification information transmission server 11 is notified.

The gateway 18 transmits the identification information received from the identification information transmission server 11 to the terminal 2 (30). Here, the gateway 18 refers to a device that allows information to be exchanged between communication networks. For example, the gateway 18 may be a USSD gateway or a short message service center (SMSC).

The gateway 18 delivers the identification information in the USSD format, for example, the USSD one way. The USSD is generally used as a means for transmitting information or specific commands from the GSM network. Like the data service, the USSD has a channel de-configuration method. Since the USSD command is transmitted to the home location register (HLR) of the network registered by the user, the USSD command does not change even if the network types are different. Therefore, when the identification information is transmitted in the USSD format, the identification information of the terminal 1 (20) may be transmitted even if the network types of the telecommunication companies of the terminal 1 (20) and the terminal 2 (30) are different.

The gateway 18 may check the specification of the terminal 2 30 before transmitting the identification information to the terminal 2 30. As a result of the check, when the terminal 2 30 supports the USSD push method, the identification information is transmitted by using a push method utilizing the USSD so that the identification information is displayed on the screen of the terminal 2 30. If the terminal 2 30 does not support the USSD push method, the identification information may be transmitted by a flash SMS method. In the flash SMS method, the identification information is displayed on the screen of the terminal 2 30 like a popup without sending an SMS to an inbox.

Here, the timing at which the identification information is displayed on the screen of the terminal 2 30 may be variously set. For example, the identification information is displayed before the call is connected between the terminal 1 (20) and the terminal 2 (30), the identification information is displayed while the call is connected and ringing, or the identification information is displayed after the call is terminated. Can be set to

In addition, the user may set in advance a time when the identification information is displayed before the call is connected, and a time when the identification information is displayed after the call is terminated. If the identification information is displayed after the call is terminated, the identification information is automatically displayed after disappearing for a predetermined time, or after the identification information is automatically displayed, the end signal is input through an input unit such as a keypad of the terminal 2 (30). The identification information may be continuously displayed until it is displayed. Here, the end signal may be input by the user by pressing the end button or the like.

The system for providing a caller identification information display service 10 according to an embodiment of the present invention includes a user interface server (UIS) 13, a billing interface server (BIS) 14, and a driving / maintenance server (Operation). & Maintenance Server (OMS) 150, Provisioning Management System (PMS) 16 and Request Management System (RMS) 17 may further include.

The user interface server 13 forms a transmission channel with a terminal of a caller identification information providing service subscriber to process a subscription / cancellation procedure or to register or modify identification information. Here, the transport channel may be WAP, WEB, UMB, or the like.

The billing server 14 is for processing information related to charging of the caller identification information providing service. For example, the results provided by the service are processed to generate statistical data, and billing data according to the service period and credits are generated.

The drive / maintenance server 15 is for processing process management, memory management, system failure management, etc. of the entire system 10.

The subscriber management server 16 processes the service subscription or termination process in conjunction with the database server 12, the billing server 14, and the like. For example, the short message (SMS) or the USSD can be used to handle the subscription / termination process.

The request management server 17 classifies a service to be provided according to a request and registers a corresponding service in a queue table that registers a processing task of each server.

Figure 2a shows a case of subscribing / canceling the caller identification information display service using SMS. For example, it is assumed that the service identification number of the caller identification information display service is "2767" and the service identifier is "L".

First, the terminal 1 (20) receives the message body in the form of the service identifier "L" is inserted into the message body, receives the identification number (2767) of the service as the received information, and then transmits the text message. For example, if you want to subscribe to the caller identification information display service, the message body is entered in the form of "L reg" or "L subscription", and if you want to cancel the service, "L unreg" or "L cancel". Receive a message body in the form of.

The transmitted text message is transmitted through the base station subsystem (BBS) 70, the mobile switching center (MSC) 40, and the short message service center (SMSC) 80. It is delivered to the user interface server 13 of the display service providing system 10 (S10, S11, S12, S13).

The user interface server 13 forwards the message to the request management server (RMS) 17 (S14), and the request management server 17 extracts the service identifier from the received information of the received text message or the message body, and the message. Extract keywords from the text. At this time, if the extracted keyword indicates subscription or termination, the subscriber management server 16 and billing server 14 of the subscriber management server 16 and the billing server 14 are registered in a queue table that registers the processing tasks of each server to process the subscription / cancellation process. Register the task.

Subsequently, the subscriber management server 16 processes the service subscription / termination of the terminal 1 20 (S15) and stores the subscription / cancellation information in the home location register 50 (S16). In addition, the billing information is stored in the billing server 14 (S17), a text message indicating that the subscription or termination request has been processed is transmitted to the terminal 1 (20) through the short message service center 80 (S18, S19). ).

For example, the subscriber management server 16 requests the subscriber information of the terminal 1 20 from the SMS database to check whether the service can be subscribed to, and if the subscription is possible, the subscriber server 14 and the database server. Save to (12). If service cancellation is requested, the subscriber information stored in the database server 12 is deleted and the corresponding service subscription information is deleted from the SMS database.

Figure 2b shows a case of subscribing / canceling the caller identification information display service using the USSD. For example, it is assumed that the service identification number of the caller identification information display service is "2767" and the service identifier is "L".

First, the terminal 1 20 receives a "* 2767 #" as a reception number. Subsequently, when the user requests a call connection by pressing the "SEND" button of the terminal 1 20 (S20), the base station subsystem 70, the mobile switching center 40, the home location register 50, USDD It is connected to the user interface server 13 of the caller identification information display service providing system 10 via the gateway 90 (S21, S22, S23, S24).

At this time, the user interface server 13 forms a transmission channel with the terminal in a USSD two way method, and a menu of the caller identification information display service is displayed on the screen of the terminal 1 (20). The user may process a subscription / cancellation procedure by selecting a desired process, for example, a service subscription or a service cancellation, from a menu displayed on the screen of the terminal 1 (20).

When the subscription / unsubscription process is requested, the user interface server 13 forwards the message to the request management server 17 (S25), and the request management server 17 processes each server to process the subscription / unsubscription process. The tasks of the subscriber management server 16 and the billing server 14 are registered in a queue table for registering the task.

Subsequently, the subscriber management server 16 processes the service subscription / termination of the terminal 1 20 (S15), and stores the subscription / cancellation information in the home location register 50 (S26). In addition, billing information is stored in the billing server 14 (S27). In addition, the registered or modified identification information is stored in the database server 12 (S28).

Subsequently, a text message indicating that the subscription / termination request processing is completed is transmitted to the terminal 1 20 through the short message service center 80 (S29 and S30).

On the other hand, the subscription request for the caller ID information display service, subscription cancellation request, ID information registration request or ID information modification request may be processed using a short message, USSD, WAP, WEB.

For example, similar to the service subscription / cancellation procedure using the text message described above with reference to FIG. 2A, identification information “Prince” may be registered using the text message. In this case, the terminal 1 20 receives the identification number 2767 of the corresponding service as the received information, and receives the message body in the form of "Prince IDreg" or "Prince ID registration". In this manner, the timing at which the identification information is displayed and the time for which the display is continued can also be set.

As another example, similar to the service subscription / termination procedure using the USSD described above with reference to FIG. 2B, identification information “Prince” may be registered using the USSD. In this case, the terminal 1 20 requests a call connection for "* 2767 #" as a reception number and is connected to the user interface server 13. Subsequently, a menu of the caller identification information display service is displayed on the screen of the terminal 1 (20), and the user selects a desired process among the menus displayed on the screen of the terminal 1 (20), for example, registration of identification information, modification of identification information, The information may be input by selecting a timing setting for displaying identification information and a time setting for displaying identification information.

First, when a call connection is requested from the terminal 1 (20) to the terminal 2 (30), the request is transmitted to the mobile switching center 40 (S40). The mobile telephone exchange 40 checks whether the terminal 1 20 is subscribed to the caller identification information display service through the home location register 50 (S41).

As a result of confirming to the home location register 50, when the terminal 1 (20) is subscribed to the service, the mobile telephone exchange 40 is called caller identification information that the call connection request from the terminal 1 (20) to the terminal 2 (30) The identification information transmitting server 11 of the display service providing system 10 is notified (S42). In this case, the mobile switching center 40 may notify the corresponding information using the MAP protocol, the ISUP protocol such as SS7 or Sigtran, or the SIP protocol.

Subsequently, the identification information transmission server 11 calls the identification information of the terminal 1 20 stored in the database server 12 and then transmits the called identification information to the gateway 18. At this time, the identification information may be transmitted by using the MAP protocol or by the TCP push method.

On the other hand, the mobile switching center 40 informs the identification information transmitting server 11 that the call connection from the terminal 1 (20) to the terminal 2 (30) is requested, and then the mobile switching center 60 of the terminal 1 (20). Transfer the call connection request (S44).

Subsequently, the gateway 18 transmits identification information of the terminal 1 20 to the terminal 2 30 in a USSD format (S45). The transmitted identification information is displayed on the screen of the terminal 2 (30) for a predetermined time. Here, the time for displaying the identification information may be set by the user or set by the operator, and in some cases, the time displayed may be set differently.

Subsequently, the mobile switching center 60 connects a call between the terminal 1 20 and the terminal 2 30. Here, the call connection refers to a call set up between the terminal 1 (20) and the terminal 2 (30). When the call is set up, the bell of the terminal 2 (30) rings. The display of the identification information may be continued even during a call, and may be set to disappear or immediately disappear after a certain time after the call ends.
