The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of a third generation mobile communication system interworking with an intelligent network to which the present invention is applied.

3G mobile communication system interworking with the intelligent network, as shown in the drawing,

Mobile communication network 120 consisting of outgoing mobile exchange / visitor location register 121 and incoming mobile exchange / visitor location register 1220, No.7 common line signaling network 130, roaming gateway 131, home location register (HLR) ) 132, a service control system (SCP) 133, an intelligent information system (IP) 134, and the like.

The Service Control Point (SCP) 133 manages the logic and data of the intelligent network service, controls all processes for the intelligent network service, and also supports SS7-based and IP-based intelligent network standard protocols (INAP, WIN, CAMEL). It is also linked with other network resources using.

In connection with the present invention, the service control system (SCP) 133 receives an intelligent network service request message ("Initial DP") (see Figs. 2 and 3) transmitted from the originating / receiving mobile exchange 121, 122, Create an unstructured supplementary service data notification message ("USSD Notify") containing the subscriber's business card data and send the call through the originating / receiving mobile switch (121, 122) and the home location register (132). / Send to the receiving terminal (100, 110). In addition, the service control system (SCP) 133 requests to continue the call processing to the originating / receiving mobile exchanges 121 and 122 separately from the transmission of the USSD notification message (“USSD Notify”), which causes the call processing process. Business card data can be transferred during the process.

Alternatively, the method of transmitting a business card to a specific called number is irrelevant to call processing, but in this case, the service control system (SCP) 133 is a business card transmission service request message (" Process USSD Request ") (see FIG. 4). ), Generate and send a USSD notification message ("USSD Notify").

Then, the corresponding calling / receiving terminal (100, 110) receiving the USSD notification message ("USSD Notify") extracts the card data from the USSD notification message ("USSD Notify") and outputs the screen (see FIG. 5).

2 is a flowchart illustrating a business card transmission service method for automatically transmitting a business card to a general caller according to the present invention.

When a call processing request for a business card service subscriber is received from the calling terminal (200), and a trunk connection is made between the calling mobile switching center (MSC) and the called mobile switching center (MSC) (201), the called mobile switching center (MSC) ) Transmits the intelligent network service request message "Initial DP" to the service control system (SCP) by means of VMT Terminating CAMEL Subscription Information (VT-CSI) set in the incoming visitor location register (VLR) (202). That is, the MSC checks whether the called party is a subscriber of the intelligent network service, and if the called party is an intelligent network service subscriber, sends an intelligent network service request message (“Initial DP”) to the service control system (SCP) for the corresponding intelligent network service. If not, it simply continues to perform call processing. Here, the intelligent network service request message ("Initial DP") is composed of parameter field values as shown in Table 1 below.

        parameter          meaning  Servicekey  Business card service key  CalledPartyNumber  Called number  CallingPartyNumber  Calling number  EventTypeBCSM  Trigger event type

Then, the service control system (SCP) checks the intelligent network service type with the service key value of the received business card transmission service request message " Initial DP " (i.e., checks whether it is a business card service) (203), If it is a business card service, a USSD notification message ("USSD Notify") including business card data of the business card service subscriber is generated and sent to the home location register (HLR) (204). Here, the card data is transmitted in a USSD notification message ("USSD Notify"). Here, the USSD notification message ("USSD Notify") is composed of parameter field values as shown in the following (Table 2).

        parameter             meaning  USSD-DataCodingScheme  How to code business card data  USSD-String  Business card data

Hereinafter, the USSD string (USSD-String) field (see Table 2) of the USSD notification message (" USSD Notify ") containing business card data will be described in detail.

Business card data is delivered using a USSD notification message ("USSD Notify"). The USSD Notify message (“USSD Notify”) can transmit binary data of up to 160 bytes.

The USSD-String field includes a header (Table 3) and substantial business card data (Table 4). First, the header format will be described as shown in Table 3 below. The USSD Notify message ("USSD Notify") can be used for services other than business card services, so we need to define a common header format.

 name  Size (byte)  Usage  Service id  2 byte  Service Identifier 1- Business Card Service 2- Other Services  Data format id  1 byte  Data Format Identifier 1- Text Data (Business Card Data) 2- Photo Data (JPEG, etc.) (Business Card Data) 3- Other  Total # of data  1 byte  Total number of messages when data is sent divided into several USSD notification messages  Sequence number  1 byte  If the data is sent in separate USSD notification messages, the serial number of the message  Reserved  7 byte  Extended area

Next, the card data carried in the USSD string (USSD-String) field of the USSD notification message ("USSD Notify") will be described.

The card data includes text data and photo (image) data, which are shown in Table 4 below.

 name  Size (byte)  Usage  Name  20  name  Phone 1  6  Phone # 1 (BCD format)  Phone 2  6  Phone # 2 (BCD format)  Phone 3  6  Phone # 3 (BCD format)  Address  30  address  e-mail  20  e-mail address  Homepage  20  Homepage address  Photo Position-X  2  Location-X coordinate  Photo Position-Y  2  Photo location-Y coordinate  Name Position-X  2  Position-X coordinate  Name Position-Y  2  Position-Y coordinate

On the other hand, the service control system (SCP) requests the destination mobile switch (MSC) to continue the call processing, regardless of the transmission of the USSD notification message ("USSD Notify") (206).

The home location register (HLR) forwards the USSD notification message (“USSD Notify”) received from the service control system (SCP) to the originating mobile exchange (MSC) (205).

The originating mobile switching center (MSC) sends a USSD notification message (“USSD Notify”) received from the home location register (HLR) to the calling terminal (207). That is, the MSC transmits business card data to the calling terminal.

The calling terminal extracts the business card data from the USSD notification message ("USSD Notify") received from the calling mobile switching center (MSC) and stores the card data in the terminal. Send a message ("USSD Notify ACK") to the originating mobile exchange (MSC) (209).

When the originating mobile exchange (MSC) receives the USSD response message ("USSD Notify ACK") from the calling terminal and forwards it to the home location register (HLR) (210), the home location register (HLR) returns to the USSD response message ("USSD Notify"). ACK ") to the service control system (SCP) (211).

If the business card data is larger than 160 bytes, the maximum size of the USSD string, the USSD notification message ("USSD Notify") and USSD response message ("USSD Notify ACK") transmission process is repeated (212). ). In this case, the calling terminal extracts business card data from the USSD notification message (“USSD Notify”) received from the calling mobile switching center (MSC) and stores the card data in the terminal. That is, whenever a calling terminal receives a USSD notification message (“USSD Notify”), the calling terminal extracts and stores business card data included therein.

When all business card data is transmitted, the service control system (SCP) transmits a USSD transaction release message ("Release") to the calling terminal through the home location register (HLR) and the originating mobile exchange (MSC) (213). To 215).

That is, when the service control system (SCP) sends a USSD transaction release message ("Release") to the home location register (HLR) (213), the home location register (HLR) receives it and the originating mobile exchange (MSC) (214). Then, the MSC transmits the received USSD transaction release message ("Release") to the originating terminal (215).

When the originating terminal receives the USSD transaction release message ("Release"), the calling terminal outputs all card data extracted and stored so far (216). In FIG. 2, the calling terminal outputs a screen after receiving all card data. However, the calling terminal may extract and display the card data whenever the USSD notification message (“USSD Notify”) is received.

3 is a flowchart illustrating a business card transmission service method for automatically transmitting a business card to a general called party according to the present invention.

When sending business card data to the caller, the VSC-TSI (VMSC Terminating CAMEL Subscription Information) is used because the called party is a service subscriber (see Fig. 2). Originating CAMEL Subscription Information (CSI) is used.

If the caller is subscribed to the business card service and the caller knows the information to be sent at the time of call processing to the called party, the service control system (SCP) transmits the business card data to the called party when the calling subscriber attempts the call.

When a call processing request is received from the calling terminal of the business card service subscriber to the calling mobile switching center (MSC) (300), the calling mobile switching center (MSC) is controlled by the O-CSI set in the calling visitor location register (VLR). An intelligent network service request message ("Initial DP") requesting to provide the intelligent network service is transmitted to SCP (301). That is, the MSC checks whether the originator is a subscriber of the intelligent network service, and if the originator is an intelligent network service subscriber, sends an intelligent network service request message (“Initial DP”) to the service control system (SCP) for the intelligent network service. If not, it simply continues to perform call processing. Here, the intelligent network service request message ("Initial DP") is as shown in Table 1 above.

The service control system (SCP) checks the type of the intelligent network service using the service key value of the intelligent network service request message ("Initial DP") received from the originating mobile switching center (MSC) (ie, whether it is a business card service). 302, if it is a business card service, generates a USSD notification message ("USSD Notify") containing the business card data of the business card service subscriber and transmits it to the home location register (HLR) (303).

At this time, if the EventTypeBCSM parameter of the intelligent network service request message ("Initial DP") is "collectedInfo", the subscriber transmits the card data to the called number because the subscriber originated the call. In addition, the USSD notification message ("USSD Notify") is composed of parameter field values as shown in Table 2 above, and only text data is transmitted to the first transmitted card data, and image data (Image Data) is not transmitted Image data (Image Data) is transmitted through the process of repeatedly transmitting the USSD notification message ("USSD Notify").

On the other hand, although not shown in the figure, the service control system (SCP) requires the originating mobile switching center (MSC) to continue the call processing regardless of the transmission of the USSD notification message ("USSD Notify").

The home location register (HLR) forwards the USSD notification message ("USSD Notify") received from the service control system (SCP) to the destination mobile switch (MSC) (304).

The destination mobile switching center (MSC) transfers the USSD notification message (“USSD Notify”) transmitted from the home location register (HLR) to the destination terminal to transmit business card data (305).

The called terminal extracts the business card data from the received USSD notification message ("USSD Notify") and stores it in the terminal, and the USSD response message ("USSD Notify ACK") corresponding to the response message that the USSD notification message ("USSD Notify") has been received. ) Is sent to the destination mobile exchange (MSC) (307).

The incoming mobile exchange (MSC) then forwards a USSD response message (“USSD Notify ACK”) to the home location register (HLR) (308).

The home location register (HLR), which has received the USSD response message ("USSD Notify ACK"), forwards the USSD response message ("USSD Notify ACK") to the service control system (SCP) (309).

If the card data is larger than 160 bytes, which is the maximum size of the USSD string, the USSD notification message ("USSD Notify") and USSD response message ("303" to "309") described above are used. "USSD Notify ACK") repeats the transmission process (310).

Even in this case, the called terminal extracts the business card data from the USSD notification message ("USSD Notify") received from the called mobile switching center (MSC) and stores it in the terminal. That is, each time the receiving terminal receives a USSD notification message ("USSD Notify"), it extracts and stores the card data contained therein.

When all business card data is transmitted, the service control system (SCP) transmits a USSD transaction release message ("Release") to the destination terminal through the home location register (HLR) and the destination mobile switch (MSC) (311). To 313).

That is, when the service control system (SCP) sends a USSD transaction release message ("Release") to the home location register (HLR) (311), the home location register (HLR) receives it and receives the MSC (312). Then, the MSC transfers the received USSD transaction release message ("Release") to the called terminal (313).

When the called terminal receives the USSD transaction release message ("Release"), it outputs all the card data extracted and stored so far (314). In FIG. 3, the receiving terminal outputs the screen after receiving all the card data. However, the card may be extracted and output on the screen whenever the USSD notification message (“USSD Notify”) is received.

4 is a flowchart illustrating a business card transmission service method for automatically transmitting a business card to a specific called number according to the present invention.

The caller (here, the subscriber of the business card transmission service) requests the business card transmission through the USSD service by inputting a 'USSD service code' and a 'called number' at the calling terminal (400).

By the caller's request, the calling terminal generates a business card transmission service request message ("Process USSD Request") using the inputted 'USSD service code' and 'called party number', and then sends it to the calling MSC. Transmit to service control system (SCP) via home location register (HLR) (401, 402, 403). That is, when the calling terminal transmits a business card transmission service request message ("Process USSD Request") to the calling mobile switching center (401), the calling mobile switching center (MSC) sends a business card transmission service request message ("Process USSD Request"). Receives and passes to the home location register (HLR) (402). Then, the home location register (HLR) receives the business card transmission service request message ("Process USSD Request") and delivers to the service control system (SCP) (403).

Here, the business card transmission service request message ("Process USSD Request") is composed of parameter fields as shown in Table 5 below. That is, the business card transmission service request message includes a data coding scheme (USSD-DataCodingScheme) field indicating a data coding method and a USSD string (USSD-String) field indicating a service code.

        parameter            meaning  USSD-DataCodingScheme  Coding method  USSD-String  Service code

When the service control system (SCP) receives the business card transmission service request message ("Process USSD Request") from the home location register (HLR), the caller sends a business card using the service code of the business card transmission service request message ("Process USSD Request"). Check whether the user is subscribed to the service (404), if the subscriber is a business card service subscriber generates a USSD notification message ("USSD Notify") containing the business card data for the subscriber and transmits to the home location register (HLR).

Here, the USSD notification message ("USSD Notify") is composed of parameter fields as shown in the following (Table 6).

        parameter             meaning  USSD-DataCodingScheme  How to code business card data  USSD-String  Business card data

If not a business card service subscriber, the service control system (SCP), although not shown in FIG. 4, sends a 'business card service unavailable message' to the calling terminal through the home location register (HLR) and the calling mobile switch.

In the method of transmitting the 'business card no service message', "cannot provide business card data transmission service" (or "not a business card service subscriber") to send a USSD notification message ("USSD Notify") carrying data There is a method, and a method of sending a message ("Process USSD ack") for a business card transmission service request and ending without doing nothing without transmitting a message indicating that a business card transmission service cannot be provided.

Here, "Cannot provide business card data transmission service" (or "not a business card service subscriber") means a USSD notification message ("USSD Notify") carrying data and a response message ("Process") for a business card transmission service request. USSD ack ") is collectively referred to as 'business card unavailable message'.

On the other hand, when the Home Location Register (HLR) forwards the USSD notification message (“USSD Notify”) received from the service control system (SCP) to the destination mobile switching center (406), the destination mobile switching center (MSC) receives the received USSD. The notification message ("USSD Notify") is forwarded to the called terminal (407).

The destination terminal extracts the card data from the USSD notification message ("USSD Notify") received from the destination mobile switching center (MSC), stores the card data in the terminal, and responds to the USSD response corresponding to the response message that the USSD notification message ("USSD Notify") was received. Send a message ("USSD Notify ACK") to the destination mobile exchange (MSC) (409).

When the MSC receives a USSD response message ("USSD Notify ACK") from the called terminal and delivers it to the home location register (HLR) (410), the home location register (HLR) returns the USSD response message ("USSD Notify"). ACK ") to the service control system (SCP) (411).

Although not shown in FIG. 4, if the card data is larger than 160 bytes, the maximum size of the USSD string, the USSD notification message ("USSD Notify") and USSD response message ("USSD Notify ACK") described above. ) The transmission process is repeated. Even in this case, the called terminal extracts the business card data from the USSD notification message ("USSD Notify") received from the called mobile switching center (MSC) and stores it in the terminal. That is, each time the receiving terminal receives a USSD notification message ("USSD Notify"), it extracts and stores the card data contained therein.

Once all business card data has been transmitted, the service control system (SCP) sends a USSD transaction release message ("Release") to the home location register (HLR) (412).

When the Home Location Register (HLR) forwards the USSD transaction release message ("Release") received from the service control system (SCP) to the destination mobile switcher (MSC) (413), the MSC will do so. It receives and delivers to the called terminal (414).

When the called terminal receives the USSD transaction release message ("Release"), it outputs all the card data extracted and stored so far (415). In FIG. 4, the receiving terminal outputs the screen after receiving all the card data. However, the receiving card may extract and display the card data whenever the USSD notification message (“USSD Notify”) is received.

In the above, the caller and the other called party have been described above. However, when the calling subscriber inputs his / her phone number as the called number to view his / her business card, the card data is transmitted to his calling terminal. In this case, the USSD notification message ("USSD Notify") transmission from the service control system (SCP) is received through the originating mobile exchange instead of the incoming mobile exchange, as shown in the figure.

5 is an explanatory diagram of a business card data output method in the terminal according to the present invention.

After receiving the card data, the terminal extracts the card data from the USSD notification message ("USSD Notify"), and then, as shown in the drawing, the card data (for example, name, Address, etc.) and also stored in the address book of the terminal.

In case of receiving image data in JPEG format or the like, all messages transmitted after receiving the final message may be output or may be output in order of receiving the message.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited by the drawings.
