Here, the coupon information is stored in the storage unit 430 coupon information corresponding to the coupon number in the form of a mapping table.

Next, the control unit 440 transmits the coupon information retrieved by the coupon identification information processing unit 420 to the SMS / MMS server 380 (S670), and the message (ie, SMS or MMS) containing the corresponding coupon information. Request creation Here, the controller 440 may set and transmit a message format (ie, SMS and MMS) when transmitting coupon information to the SMS / MMS server 380. That is, the controller 440 sets the message format transmitted to the mobile communication terminal 100 based on the type (model) of the mobile communication terminal 100 or the contents included in the coupon information to the SMS / MMS server 380. send.

Next, the SMS / MMS server 380 generates a message (ie, SMS or MMS) including the transmitted coupon information (S680). Next, the generated message (ie, SMS or MMS) is transmitted to the corresponding mobile communication terminal 100 (S690). Here, the SMS / MMS server 380 generates a message including the coupon information in the set message format when the coupon information and the message format (ie, SMS and MMS) are set and transmitted together from the coupon management server 400.

Next, the mobile communication terminal 100 receives the message transmitted from the SMS / MMS server 380, and stores the coupon information included in the received message (S700). Thereafter, the user of the mobile communication terminal 100 may purchase / exchange a product (or a service) using the mobile coupon displayed on the screen of the mobile communication terminal 100.

On the other hand, if the analysis result in step S630 is not the phone number of the coupon management server (No in S630), the MSC 310 requests the HLR 360 MSC address for the analyzed destination number. Thereafter, when the MSC address for the corresponding destination number is transmitted from the HLR 360, it is determined that the corresponding destination number is a general telephone number, and requests a call connection of the called terminal. If the MSC address for the corresponding destination number is not transmitted from the HLR 360, it is determined that the corresponding destination number is not a general telephone number.

In addition, when the destination number is not the general phone number and the phone number of the coupon management server, the MSC 310 determines that the destination number is the wrong number, and corresponds to the corresponding mobile communication terminal 100 through the communication unit 311. Error message indicating that the coupon identification information cannot be transmitted. FIGS. 7A and 7B illustrate a mobile coupon displayed on a mobile communication terminal in an apparatus for providing a mobile coupon according to an embodiment of the present invention.

As shown in FIG. 7A, when only the text is included in the coupon information for a certain product, an SMS format message is transmitted to the mobile communication terminal 100. Thus, the mobile communication terminal 100 stores the coupon information included in the transmitted message, and if you want to use the coupon information for a predetermined product, the mobile coupon 110 on the screen of the mobile communication terminal 100 To display and use.

As shown in FIG. 7B, when an image or flash form is included in coupon information for a certain product, a message in MMS format is transmitted to the mobile communication terminal 100. Thus, the mobile communication terminal 100 stores the coupon information included in the transmitted message, and if you want to use the coupon information for a predetermined product thereafter, the mobile coupon 110 on the screen of the mobile communication terminal 100 Display and use.

For example, the mobile coupon 110 displayed on the screen of the mobile communication terminal 100 includes store information (for example, A-Mart) that can use the coupon, and information on a product to which the coupon is applied (for example, For example, a product type, a discounted price, a period of use, etc.) and a coupon number (or a barcode) are described.
