Description

[Technical field]

[0001] The present invention relates to a system for activating an eSIM, and more particularly to an eSIM activation system and program that simplifies procedures and improves user convenience. [Background technology]

[0002] [Prior Art] eSIM enables data communication using a smartphone's internal communication functions without using a SIM card, and most recent smartphones are equipped with this function. Just as a SIM card enables voice calls and data communication through a contract with a telecommunications carrier, an eSIM also enables data communication after being activated by a telecommunications carrier.

[0003] The activation method is that the user selects an eSIM package product at a store, pays in person or at a vending machine, and then scans the 2D barcode printed inside the package with their device, which then displays a navigation site that directs the user to the activation site (first stage access).

[0004] The user then enters their email address on the redirection site and submits it, at which point the URL of the activation site is displayed in the user's email address. When the user enters an authentication code such as a one-time password to access the URL (activation site) (second-stage access), a two-dimensional installation barcode is displayed. The user then reads the two-dimensional installation barcode using the communication settings to complete the activation process.

[0005] In other words, two stages of access were required: a first stage to access the redirection site, and a second stage to access the activation site. In addition, users had to select a telecommunications carrier in advance and purchase a package product, and it was not easy for them to select the most suitable mobile communications plan from among telecommunications carriers based on their usage status and plans.

[0006] [Related Technology] In addition, related prior art documents include JP 2012-109973 A, “Method and apparatus for access control client-assisted roaming” (Patent Document 1) and JP 2019-149188 A, “Server apparatus, communication system, communication method, and program” (Patent Document 2).

[0007] Patent document 1 shows that a mobile device detects a roaming state, and in response evaluates available eSIMs, and if compatible, the eSIM is loaded and made available for use.

[0008] Patent Document 2 describes a service for renting actual SIM cards, in which the SIM card is dispensed by reading a QR code (registered trademark) corresponding to a user ID delivered upon user registration. [Prior art documents] [Patent documents]

[0020] The present invention causes the activation server to function in the above program so as to require the user terminal to input the authentication code transmitted at the time of the link notification when the user terminal accesses the link of the activation site.

[0021] The present invention is a program for causing an activation server to input a usage period and usage capacity of a mobile communication plan when accepting an eSIM application, and to select one of a plurality of mobile communication plans in response to the input. The user The function of the service is to provide the service to the user and allow them to make a selection and make a purchase.

[0022] In the above program, the present invention causes the activation server to function in such a way that, when a two-dimensional barcode is displayed on a user terminal, the activation server causes the terminal device into which an email address has been input to print out the two-dimensional barcode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. [Outline of the embodiment] In an eSIM activation system (this system) according to an embodiment of the present invention, an application for eSIM use (eSIM application) is made on an eSIM terminal device installed by an operator of an activation server, the user selects and pays for a mobile communications plan depending on their usage status and plans, and the user enters their email address on the display screen of the eSIM terminal device. The activation server then transmits the access destination (URL: Uniform Resource Locator) of the activation site to the user terminal to which the email address is set, the user terminal accesses the activation site from the URL (first stage access), enters a one-time authentication code, and a two-dimensional barcode for installation is displayed on the user terminal. The two-dimensional barcode is then read into the communication settings of the user terminal to complete activation. This makes it possible to easily activate an eSIM on a user terminal with a single step of access using the eSIM terminal device.

[0028] In addition, when selecting a mobile communications plan for a user, the system recommends the most suitable mobile communications plan based on the user's mobile communications usage status and usage plans, allowing the user to easily select the most suitable mobile communications plan. In other words, before purchasing an eSIM, users can compare multiple plans based on their communication conditions and make a purchase, and then quickly activate their device so it can be used.

[0029] In addition, this system enables users to easily activate eSIMs for mobile communication plans in multiple countries using a single eSIM terminal device when traveling to multiple foreign countries.

[0030] [This system: Figure 1] This system will be described with reference to Fig. 1. Fig. 1 is a schematic diagram of the configuration of this system. As shown in FIG. 1, the system includes an activation server 1, an eSIM terminal device 2, a user terminal 3 such as a user's smartphone or tablet, and a network 4. The eSIM terminal device 2 is installed at an airport, a train station, etc., connected to the activation server 1 via a network 4, and managed by an operation company that manages the activation server 1.

[0031] [Parts of this system] Each part of this system will now be described. [Activation Server 1] The activation server 1 includes a control unit 11, a storage unit 12, and an interface unit 13, and uses the eSIM terminal device 2 to issue an activation code and the like for activating an eSIM in a user terminal 3.

[0032] The storage unit 12 stores processing programs such as activation code issuing processes, as well as data and parameters required for the processes. Necessary data includes multiple mobile communication plans (including fees), user information (including email addresses) corresponding to application IDs, and payment information. The control unit 11 executes a processing program stored in the storage unit 12 to realize an activation code issuing process and the like. The interface unit 13 is an interface unit for connecting the activation server 1 to the network 4 .

[0033] The activation server 1 provides the eSIM terminal device 2 with a mobile communication plan of a telecommunications carrier that is optimal according to the user's eSIM usage plan (planned period of use) and usage status (planned communication capacity). When providing mobile communication plans, it is easy for the user to select if not only a plan with the desired communication capacity, but also plans with capacities before and after the desired capacity are provided together with the price.

[0034] In addition, the activation server 1 performs payment processing for purchasing an eSIM via the eSIM terminal device 2 using a credit card, electronic money, etc. Furthermore, the activation server 1 performs processing for issuing activation codes and the like, which will be described later.

[0035] [eSIM terminal device 2: Figure 2] Next, the eSIM terminal device will be described with reference to Fig. 2. Fig. 2 is a configuration block diagram of the eSIM terminal device. The eSIM terminal device 2 is a terminal device that is installed at an airport, a train station, or the like, and is managed by the operating company of the activation server 1. As shown in FIG. 2, the eSIM terminal device 2 has a control unit 21, a storage unit 22, an interface unit 23, a touch panel display 24, and a printer (printing device) 25.

[0036] The storage unit 22 stores a processing program for operating the eSIM terminal device 2. The interface unit 23 is an interface unit that is connected to the network 4 and is connected to a touch panel display 24 and a printer 25 . The touch panel display 24 has the functions of a display unit and an input unit, and prompts the user to input their usage plans and usage status, displays the mobile communication plan that is most suitable for the user, displays a payment screen, and prompts the user to input their email address.

[0037] If a user is not aware of his or her own mobile communication usage, the system may ask the user to enter the details of his or her usual Internet usage and the amount of time spent on the Internet in a questionnaire format, and an appropriate usage capacity may be recommended. The printer 25 prints out on paper a two-dimensional barcode that activates the eSIM described below.

[0038] When the user selects and inputs the eSIM usage plan (usage period: ○ month ○ day - △ month △ day) and usage status (communication capacity: ○ MB or △ G bytes, etc.) on the touch panel display 24, the control unit 21 transmits the usage plan and usage status input by the user to the activation server 1 via the interface unit 23.

[0039] The control unit 21 receives an optimal mobile communication plan from among a plurality of communication carriers according to the user's usage schedule and usage situation from the activation server 1, and displays the mobile communication plan on the touch panel display 24. Note that even if the same communication carrier is used, the optimal plan is submitted from among a plurality of plans.

[0040] When the user selects from the mobile communication plans provided on the touch panel display 24, the control unit 21 displays a payment screen on the touch panel display 24, prompts the user to make payment, and performs payment processing such as credit card payment. The payment processing may be performed by credit card payment through a credit card insertion slot of the eSIM terminal device 2, or electronic payment may be performed by reading a two-dimensional barcode for electronic payment with a two-dimensional barcode reader of the eSIM terminal device 2.

[0041] When the payment process is completed, the control unit 21 displays an input screen on the touch panel display 24 for entering the email address to be used on the user terminal 3, and when the email address is entered, the control unit 21 encrypts the email address and sends it to the activation server 1. When the eSIM terminal device 2 transmits an email address to the activation server 1, it also transmits the ID of the eSIM terminal device 2 in which the email address was entered. After that, a process of issuing an activation code and the like is carried out between the activation server 1 and the user terminal 3.

[0042] [User terminal 3] The user terminal 3 is a terminal of a user who purchases and activates an eSIM, and is assumed to be a smartphone, a tablet, or the like. When the user terminal 3 enters a one-time authentication code into the access destination (URL) of the activation site sent from the activation server 1 to the email address entered into the eSIM terminal device 2 and accesses the site (first-stage access), a two-dimensional barcode for activating the eSIM is issued and displayed, and when the two-dimensional barcode is read into the communication settings of the user terminal 3, an activation code and the like are set in the communication settings, and the purchased eSIM is activated. In other words, activation is achieved with a one-stage access.

[0043] On the user terminal 3, the eSIM is activated when the two-dimensional barcode issued on the communication settings screen is read. However, if the two-dimensional barcode cannot be read on the communication settings screen, the activation code and other settings must be manually configured. Typically, a two-dimensional barcode is displayed on a personal computer, and the two-dimensional barcode is read by the camera of the user terminal 3 on the communication setting screen to activate the device.

[0044] However, when a two-dimensional barcode is displayed on the display screen of the user terminal 3 and the user moves to the communication setting screen of his / her own user terminal 3, the two-dimensional barcode is no longer displayed and cannot be read on the communication setting screen, so the two-dimensional barcode must be read manually.

[0045] On the user terminal 3, when the "Manual" setting is selected at the bottom of the screen displaying the 2D barcode, in the case of an Android (registered trademark) terminal, the code (activation code) provided by the provider is copied and pasted into the communication setting screen to set it, and in the case of an iPhone, the SM-DP+ address and activation code are copied and pasted into the communication setting screen to set it.

[0046] [Processing of this system: Figures 3 and 4] Next, the processing in this system will be described with reference to Figures 3 and 4. Figure 3 is a flow chart showing the first half of the processing in this system, and Figure 4 is a flow chart showing the second half of the processing in this system. As shown in FIG. 3, the process in this system begins when a user applies for an eSIM on the display screen of the eSIM terminal device 2 (S1).

[0047] When an eSIM application is made, the eSIM terminal device 2 transmits the eSIM application to the activation server 1, and the activation server 1 assigns an application ID. Furthermore, when the usage schedule and usage status of the user related to the application are input, the eSIM terminal device 2 transmits the information and the application ID to the activation server 1 (S2).

[0048] The activation server 1 transmits a mobile communication plan of a carrier that is optimal for the information and an application ID to the eSIM terminal 2, and displays the mobile communication plan on the touch panel display 24 of the eSIM terminal 2 (S3). When a mobile communication plan is selected by the user, the eSIM terminal device 2 transmits the selected plan and the application ID to the activation server 1 (S4).

[0049] Then, the activation server 1 displays a payment screen for purchasing an eSIM on the touch panel display 24 of the eSIM terminal device 2, which requests payment of the usage fee for the plan, and performs payment processing (S5). In the payment processing, the activation server 1 stores the completion of payment for the communication plan corresponding to the application ID. Next, when the payment for the eSIM purchase is completed, an input screen for prompting the user to input an email address to be used with the user terminal 3 is displayed on the display screen of the touch panel display 24 of the eSIM terminal device 2 (S6).

[0050] Then, when the user's email address is entered on the touch panel display 24 (S7), the eSIM terminal device 2 transmits the entered email address and application ID to the activation server 1 (S8). After this, processing is carried out between the activation server 1 and the user terminal 3.

[0051] Next, as shown in FIG. 4, the activation server 1 transmits the access address (URL) of the activation site and a one-time authentication code to the email address transmitted from the eSIM terminal device 2 (S11). When the user terminal 3 receives the access destination of the activation site and the authentication code at the email address to be used (S12), the user accesses the access destination and inputs the authentication code at the accessed site (S13).

[0052] When the activation server 1 authenticates the authentication code for the access destination, the user terminal 3 displays a two-dimensional barcode of the activation code (installation code) (S14). The activation code and the like are set in the communication settings, and the user terminal 3 reads the installation code on the communication settings screen to activate the purchased eSIM (S15). Thus, activation is completed.

[0053] Next, additional functions of the present system will be described. [Printing function of eSIM terminal device] The printer 25 of the eSIM terminal device 2 operates the eSIM terminal device 2 to print on paper a two-dimensional barcode for activation and provide it to the user who has purchased an eSIM.

[0054] In this system, the user terminal 3 needs to access the activation server 1 to display a two-dimensional barcode for activation, and then read the two-dimensional barcode on the communication setting screen. However, as mentioned above, it is difficult to read the displayed two-dimensional barcode with an internal application, and manual setting operations are required, which is a tedious task for users who are not familiar with such operations.

[0055] Therefore, at the same time that the activation server 1 displays the two-dimensional barcode for activation on the user's user terminal 3, the printer 25 of the eSIM terminal device 2 into which the user's email address has been entered prints out the two-dimensional barcode on paper. That is, the activation server 1 receives the ID of the eSIM terminal device 2 entered in correspondence with the email address, and causes the printer 25 of the eSIM terminal device 2 with that ID to print a two-dimensional barcode.

[0056] The user reads the two-dimensional activation barcode printed on paper with the camera of the user terminal 3 and activates the eSIM. If the user terminal 3 has a communication environment such as Wi-Fi, the two-dimensional activation barcode printed on paper can be read later and activation can be performed at a leisurely pace, thereby avoiding queues and congestion in front of the eSIM terminal device 2. Furthermore, once a 2D barcode has been activated, it will become invalid.

[0057] [Local and roaming carriers] In this system, when providing eSIM services to a user, the service contents of the local carrier providing the eSIM service and the e-roaming carrier service are displayed on the touch panel display 24 of the eSIM terminal device 2 so that the two can be compared.

[0058] Typically, roaming carrier services are cheap but of poor quality, while local carrier services are more expensive but of good quality, and the touch panel display 24 of the eSIM terminal device 2 displays the prices and quality (for example, quality is displayed as a five-point rating mark or numbers, etc.) so that they can be compared.

[0059] [Tourist information, etc.] In this system, when the activation server 1 transmits the access destination of the activation site to the user terminal 3, the activation server 1 may display or attach tourist information for the travel destination to the e-mail. In addition, the activation server 1 may print tourist information for the travel destination on the two-dimensional barcode printing paper of the eSIM terminal device 2.

[0060] The eSIM terminal device 2 may be equipped with a camera, and a photograph of the user may be taken with the camera and combined with a famous image of a tourist spot or other image, and the photograph may be attached to an email and sent to the user terminal 3, or may be printed on paper. The image processing above uses AR (Augmented Reality) technology. AR is a technology that combines CG (digital information) with actual images and videos (the real world) to create a virtual space in the real world.

[0061] Furthermore, the activation server 1 may provide photos and illustrations of tourist attractions and other information in lieu of tourist information. In particular, when art data such as an illustration is attached to an e-mail, the activation server 1 provides it as NTF. NTF (Non-Fungible Token) is non-fungible digital data created based on the blockchain.

[0062] [Processing method in this system] Also, a method for activating an eSIM on a mobile device can be described as follows: This is a processing method for activating an eSIM in a mobile terminal, in which an activation server accepts a user's eSIM application from a terminal device, provides a mobile communication plan to the terminal device, and when the plan is selected and purchased on the terminal device, sends a link to an activation site to the user's email address entered from the terminal device, and when the link is accessed from the user's user terminal, a two-dimensional barcode that activates the eSIM is displayed on the user terminal, and when the two-dimensional barcode is read into the communication settings of the user terminal, activates the eSIM in the user terminal.

[0063] In the above processing method, when the user terminal accesses the link of the activation site, the activation server makes the user input the authentication code transmitted at the time of the link notification.

[0064] In addition, in the above processing method, the activation server inputs the usage period and usage capacity of the mobile communication plan when accepting an eSIM application, and provides a plurality of mobile communication plans to the terminal device in accordance with the input, allowing the terminal device to select and purchase the plan.

[0065] [Effects of the embodiment] This system ba, e After applying for a SIM, the user selects a mobile communication plan according to their usage status and usage schedule, makes a payment, and inputs the user's email address on the display screen of the eSIM terminal device 2. The activation server 1 then 3 The URL of the activation site is sent to the eSIM terminal device 2, and the user terminal 3 accesses the activation site from that URL and enters a one-time authentication code to display a two-dimensional barcode for installation on the user terminal 3. The two-dimensional barcode is then read into the communication settings of the user terminal 3, completing the activation. This has the effect of making it easy to activate the eSIM in a single step using the eSIM terminal device 2.

[0066] In addition, according to the present system, when selecting a mobile communication plan for a user, the system recommends the most suitable mobile communication plan based on the user's mobile communication usage status and usage plans, thereby enabling the user to easily select the most suitable mobile communication plan.

[0067] In addition, according to this system, when a user travels to multiple foreign countries, the user can easily activate eSIMs for mobile communication plans in multiple countries using a single eSIM terminal device 2. [Industrial Applicability]

[0068] The invention provides a single-step access for eSIM activation, making it easier for users to find the optimal mobile communication plan. purchase The present invention is suitable for an eSIM activation system and program that can [Explanation of symbols]
