The user terminal 100 includes a 3G, 4G, 5G mobile communication terminal having a mobile communication and/or short-range wireless communication function equipped with a microprocessor and equipped with a memory means such as a smart phone. and various applications may be installed to provide various services to users.

In the user terminal 100 , a dedicated data communication service App 110 may be installed, and a Subscriber Identity Module (SIM) card 130 may be mounted thereon.

The user terminal 100 may access the service server 200 through the App 110 , register the SIM card 130 , and purchase a data communication product desired by the user. In addition, the user terminal 100 may use the data communication service of the mobile communication service provider who purchased the data communication product by using the SIM card 130 .

Here, there may be various data communication products in which data communication product attributes such as a country using a data communication service, a telecommunication company, data capacity, data usage period, and price are combined differently. For example, there may be a data communication product A, which allows you to use 3GB of data for 5,000 won for 3 days, and a data communication product B, where you can use unlimited data capacity for 15,000 won for 7 days through 'AIS', an MNO in Thailand. . In addition, there may be a C data communication product that can use 5GB for 3 days at 20,000 won in Thailand, Indonesia, and Vietnam.

For example, it may be necessary to adjust the allocation of Op IMSI (Operational IMSI) for each data communication product by analyzing the user's data communication product purchase pattern. In the case of some mobile operators, the application of data communication products to a specific IMSI may not be performed in real time. Therefore, it is necessary to allocate data communication products for each IMSI in advance. If the demand for each data communication product does not match, the IMSI resources may not be efficiently utilized. In order to prevent this, it may be necessary to efficiently allocate the Op IMSI for each data communication product through data communication product purchase pattern analysis.

The product sales management server 210 may provide the data communication product information generated in step S210 to the MNO 300 (S215). According to an embodiment, the MNO 300 may confirm the data communication product information provided in step S215 and approve or reject the sale of the data communication product. Of course, it is also possible to omit the step (S215).

Thereafter, the user terminal 100 may request SIM card registration from the product sales management server 210 through the App 110 (S220). In step S220, the SIM card registration request includes an Integrated Circuit Card Identifier (ICCID) of the SIM. In addition, personal information such as a user's email address and a user's phone number may be included in the SIM card registration request. According to an embodiment, when the QR code displayed on the SIM card is photographed and recognized using a camera (not shown) provided in the user terminal 100 , the SIM card registration screen provided by the App 110 is automatically displayed on the user terminal 100 . ) can also be displayed.

The data communication product purchase information transmitted to the MNO 300 may include ICCID, Op IMSI, data communication product ID, product attribute information, and the like. The Op IMSI is determined as one of the IMSIs included in the plurality of SIM profiles provided by the MNO 300 . The MNO 300 may provide a data communication service to the user terminal 100 by using the data communication product purchase information transmitted in step S255 .

Meanwhile, the provisioning server 230 may transmit data communication product purchase information including the Op IMSI to the user terminal 100 (S260). In step S260, Ki and Opc corresponding to the corresponding Op IMSI are also transmitted.

Thereafter, the user terminal 100 may use the data communication service by using the Op IMSI, Ki, and Opc transmitted in step S260 (S265).

And when the use of the purchased data communication product is completed, the SIM card 130 mounted on the user terminal 100 may transmit a data communication product use completion message to the provisioning server 230 (S270).

The provisioning server 230 may transmit a data communication product use completion confirmation message to the user terminal 100 (S275), and the SIM card 130 may delete purchased data product information (S280).

The user terminal 100 may request SIM card registration from the product sales management server 210 through the App 110 (S310). The product sales management server 210 may perform a SIM card registration process and transmit a SIM registration completion message to the user terminal 100 (S315). Steps S305, S310, and S315 correspond to steps S205, S220, and S225 of FIG. 2, respectively.

Next, the user can determine the data communication product conditions that he or she wants through the menu provided by the App (110) (S320). The user can determine the conditions of the data communication product by combining the country, the telecommunication company, the data capacity, and the data usage period in the way he or she wants.

The product sales management server 210 may receive a data communication product condition desired by the user from the user terminal 100 ( S325 ).

Then, the product sales management server 210 may determine a price corresponding to the data communication product condition in real time according to a predetermined price policy (S330). A policy algorithm for determining a price for each data communication product condition may be prepared in advance.

Thereafter, the product sales management server 210 may transmit and register data communication product conditions to the MNO 300 ( S335 ).

The product sales management server 210 may provide the user terminal 100 with price information of a product corresponding to a data communication product condition that the user wants to purchase ( S340 ).
