[0002] In daily life, the common self-service invoicing method for consumers is to print a QR code receipt for each order and give it to the user. The user uses his or her mobile phone to scan the code to enter the invoicing interface, fill in the invoice header information and submit the invoice. At the same time, companies generally provide APP (Application) or mini-programs to query previous uninvoiced orders and issue invoices on demand.

[0003] With the emergence of NFC technology, such as the "touch and pay" technology, it provides a simpler operation method and also brings new ideas on how to better improve user perception.

[0004] However, if the tap-and-pay technology is adopted, users will inevitably need to install the corresponding supporting APP on their mobile phones to receive and parse the NFC sensing content in order to complete the subsequent invoicing business.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Figure 1 is a flowchart of a self-service invoicing method based on NFC and 5G messaging according to an embodiment of the present invention, as Figure 1 shown, the method includes the following steps: S1, the 5G mobile terminal enters the sensing range of the NFC tag, activates the NFC tag through the radio frequency field and reads the pre-stored data therein, and the pre-stored data is "smsto: special SMS service number: SMS content".

[0020] Specifically, an NFC tag reading and writing device is used to write pre-stored data into the NFC tag. The pre-stored data adopts the smsto scheme, and its basic format is "smsto:ChatBot special service number:sms content". Smsto is a URI (Uniform Resource Identifier) scheme, mainly used for web links or Intents in mobile applications, aiming to trigger the default SMS application on the device and pre-fill the recipient number and sms content. Among them, (smsto:) is the protocol header, which is a fixed part, telling the browser or operating system that this is a link for initiating an SMS sending action. The ChatBot special service number is a telephone number, following immediately after smsto: and cannot contain spaces. The sms content is a query parameter and is an optional content.

[0021] In the present invention, the ChatBot special service number starts with 106, and the sms content is "invoice". For example, the pre-stored data is "smsto:106*****:invoice". The sms special service number needs to be applied for in advance from a communication operator (such as a telecom operator). The NFC tag can adopt the 13.56 MHz frequency band. After the 5G mobile terminal approaches and touches the NFC tag, an inbound communication request is sent.

[0022] Adopting the "smsto: protocol link", there is no need to develop an App, and the built-in SMS application of the mobile phone is automatically invoked, which is compatible with all Android mobile terminals.

[0023] The mobile terminal can be an electronic device such as a mobile phone, a tablet computer, or a smartwatch.

[0024] S2, the mobile terminal reads the pre-stored data, automatically invokes the built-in SMS application, and sends an SMS upstream to the 5G messaging service platform according to the pre-stored data.

[0025] Specifically, the 5G messaging service platform is a platform provided by a communication operator with 5G messaging service capabilities.

[0026] S3, the 5G messaging service platform forwards the upstream SMS to the ChatBot service program.

[0027] In an embodiment of the present invention, the ChatBot service program is developed and implemented through the following steps: applying to become a 5G messaging ChatBot service provider of a communication operator to dock with the 5G messaging service platform; using the Postman tool or self-built function to call the Create ChatBot interface API provided by the 5G messaging service platform to create a ChatBot and obtain the sms special service number Specifically, relevant qualification materials need to be prepared, and one operator is selected from telecommunications / China Unicom / China Mobile operators to apply to become a 5G messaging ChatBot service provider of the communication operator, that is, a CSP (Chatbot Service Provide, 5G messaging service provider). Only by becoming a CSP can one connect to the 5G messaging service platform, obtain the 5G messaging service capability, and build one's own 5G messaging service program. Specifically, through the Postman tool or self-built function, call the Create ChatBot interface API provided by the 5G messaging service platform to create a ChatBot chatbot, and obtain the short message special service number starting with 106 from the returned message to implement the ChatBot service program.

[0028] It should be noted that taking the telecommunications 5G messaging service platform as an example, only a series of interface APIs of the http protocol are open to enterprises, including various management and maintenance capabilities of CSP and ChatBot. Enterprises can use the Postman tool or build their own corresponding function interfaces to implement the operation and maintenance management of CSP and ChatBot.

[0029] S4, the ChatBot service program listens to and parses the short message content transmitted by the 5G messaging service platform, generates a rich media card message carrying the H5 page link of the invoicing application system, and sends the rich media card message downward to the 5G messaging service platform. The H5 page includes: order query, order invoicing, and invoice query pages.

[0030] S5, the 5G messaging service platform sends the rich media card message downward to the mobile terminal so that the user can enter the invoicing application system H5 page through the rich media card message of the mobile terminal to complete self-service invoicing.

[0031] Specifically, develop a ChatBot service program that connects to the 5G messaging service platform of the communication operator and integrates it as a module into the invoicing application system. The ChatBot service program implements a message notification listening class, exposes the interface call API, and registers the call address to the 5G messaging service platform, mainly used to receive the uplink short messages sent by users. From the received uplink short messages, parse out the invoicing / checking invoice instructions, assemble corresponding rich media card messages according to different instructions, and embed the direct access links without login to the corresponding functional mobile pages in the card messages, and send them downward to the user's mobile phone through the 5G messaging sending interface of the telecommunications operator's 5G messaging service platform. The user will receive the corresponding card message in the short message application of the 5G mobile terminal.

[0032] It should be noted that in the present invention, it is necessary to open the two-way mutual access network permission between the ChatBot service program and the 5G messaging service platform.

[0033] The invoicing application system has the core capability to realize invoicing and provides a self-verifiable secure access link for mobile terminals. After the user's mobile phone sends a text message instruction, it will be processed by the ChatBot service program and the user will receive a rich media card message containing the invoicing link. The user clicks on the rich media card message to enter the invoicing application system and automatically query the order / invoice based on the mobile phone number. The user can complete the invoicing by selecting an uninvoiced order and filling in the invoice header.

[0034] The entire process of self-service invoicing can be found in Figure 2 As shown, a 5G mobile terminal that supports and turns on the NFC function is used to touch the NFC tag with the content "smsto:ChatBot special service number starting with 106:invoice" to issue an entry communication request; "smsto:protocol link" will automatically call up the mobile phone's built-in SMS application, and pre-fill the ChatBot special service number starting with 106 in the NFC and the SMS content "invoice", and send the SMS, that is, send it uplink to the 5G messaging service platform; the 5G messaging service platform transmits the uplink SMS to the ChatBot service program; the ChatBot service program provides monitoring services to receive uplink SMS messages transmitted by the 5G messaging service platform; ChatBot The ot service program parses the SMS content, identifies the operation instructions, assembles the downstream message, generates a rich media card message with a link to the H5 page of the invoicing application system, and sends the source mobile phone number and the downstream message to the 5G message service platform; the 5G message service platform is again responsible for sending the rich media card message downstream to the source mobile terminal; the source mobile terminal will receive the rich media card message with a link to the invoicing application system generated by the ChatBot service program according to the content instructions of touching NFC; finally, the user clicks on the rich media card message to enter the invoicing application system, and automatically queries the order / invoice based on the mobile phone number. The user can complete the invoicing by selecting an uninvoiced order and filling in the invoice header.

[0035] As a result, users do not need to install additional APP. When the 5G mobile terminal touches the NFC tag, the built-in SMS application of the mobile phone will be automatically activated. The invoicing application system can be entered through the SMS application to complete the invoicing business, providing users with a more convenient and user-friendly self-service way to issue / obtain invoices, which better improves the user experience, saves the cost of enterprise development of APP, avoids the embarrassment of requiring users to install APP, and is easier to promote and use.

[0036] In the embodiment of the present invention, the invoicing application system adopts a front-end and back-end separation architecture, and the invoicing application system has order query, order invoicing and invoice query functions.

[0037] Specifically, the invoicing application system adopts a front-end and back-end separation architecture, uses HTML5 to implement multi-end adaptation order query, order invoicing, invoice query and other pages, as well as other invoicing-related management functions. The backend opens up relevant interfaces with the official tax system, and opens and integrates invoicing capabilities. In the invoicing application system, the order query / invoicing and invoice query H5 pages are implemented. The order query page on the mobile terminal retrieves and displays the order list to be invoiced (including order date, order amount, order items and other field information), selects one or more orders, clicks the invoice button, enters the invoice header and ticket information confirmation page, supplements or modifies the invoice header information, and clicks the confirmation button to call the backend invoicing. The invoice query page on the mobile terminal displays the invoiced information in reverse order of the invoicing time, supports selecting one or more invoices, filling in the email address, and pushing the invoice file to the email address filled in by the user.

[0038] It should be noted that due to the screen size, the display content and format of mobile terminals are limited. Therefore, the mobile H5 page is different from the PC page and needs to be developed separately.

[0039] In one embodiment of the present invention, the above-mentioned self-service invoicing method based on NFC and 5G messages also includes: generating an access link in a specific format with self-verification capability based on a customized encryption and decryption method based on mobile phone number and timestamp, thereby realizing login-free access to the mobile terminal order query page and invoice query page.

[0040] Specifically, create a ciphertext generation method, with the input parameter being the mobile phone number and the output parameter being the ciphertext. Use the configured fixed key to encrypt the "mobile phone number + current system timestamp" to generate the ciphertext. Create a ciphertext decryption verification method, with the input parameter including the mobile phone number and the ciphertext string, and the output parameter being a Boolean value (true / false). Use the configured fixed key to decrypt the ciphertext string, extract the mobile phone number and timestamp after obtaining the plaintext, and match them with the mobile phone number in the input parameter, and then verify whether the interval between the timestamp and the current system time is within the valid range (for example, set to 1 minute); if both the mobile phone number and timestamp verification pass, true is returned, otherwise false is returned. After the verification passes, the mobile phone number is directly used to query the user data table, and the matching user is found. The login is automatically completed without verifying the password, realizing login-free access to the mobile terminal order query page and invoice query page.

[0041] In the present invention, the mobile terminal access identification method can be: obtaining User-Agent information from the HttpRequest request header, detecting whether the content contains common mobile terminal device keywords (such as android, phone, mobile, pad, etc.) to determine whether it is a mobile terminal.

[0042] Implement the login-free access to the order query page and invoice query page of the mobile terminal, specifically: agree on two link formats, namely, " / h5 / order / {ciphertext string} / list" and " / h5 / invoice / {ciphertext string} / list", and generate the {ciphertext string} in the link by the ciphertext generation method. When requesting access, use the mobile terminal access discrimination method to determine whether it is a mobile terminal request; if it is a mobile terminal request, read the {ciphertext string} in the link, call the login-free capability, and complete the background login; if it is not a mobile terminal request or the login-free fails, then jump to an error-friendly prompt page. Thus, provide users with the function of convenient access and use of invoicing on the mobile phone.

[0043] It can be understood that the above method of the present invention can not only be applied to the self-service invoicing scenario, but also replace various traditional service modes of scanning codes or using APP operations.

[0044] In summary, according to the self-service invoicing method based on NFC and 5G messages of the embodiments of the present invention, a new and convenient self-service invoicing method is provided by combining two new technologies of NFC and 5G messages. By docking with the 5G message service platform, the ChatBot service program is implemented to complete complex rich media communication interaction scenarios. Users do not need to install an additional APP. When the 5G mobile terminal touches the NFC tag, the built-in SMS application of the mobile phone is automatically invoked, and the invoicing application system can be entered through the SMS application to complete the invoicing business, providing users with a more convenient and friendly self-service invoicing / obtaining ticket method, better improving the user experience, saving the cost of enterprise APP development, avoiding the embarrassment of requiring users to install the APP, and being more conducive to popularization and use. Customize a set of secure and reliable encryption and decryption methods based on the mobile phone number and timestamp to generate access links in a specific format, and implement the login-free access to the mobile H5 page.
