Description

Method for Realizing SMS Coupons by Utilizing Data SMS and STK Menu

technical field

The invention relates to a method in the technical field of telecommunications, in particular to a method for realizing short message coupons by using data short messages and STK menus.

Background technique

With the popularization of mobile phones, more and more merchants hope to release their preferential information to users through mobile phones to attract customers. At present, sending coupons by SMS is nothing more than using ordinary SMS to send a text description, and finally the merchant confirms the user's use by checking this text. However, anyone can use a mobile phone to edit this text message, and it can also be forwarded to others. People with a little knowledge of GSM can even forge an identical text message by using ordinary card reader equipment, so as to achieve the purpose of defrauding preferential products. These imperfections greatly limit the use of coupons by SMS.

After searching the existing technical documents, it is found that: Chinese patent application number: 02100145.6, title: use mobile phone short message service to realize electronic coupon (eCoupon) system, publication number: CN1432949. The technology claims that the electronic coupon (eCoupon) system can be realized by using mobile short message service, which can replace traditional coupons or discount cards and provide services for corporate marketing and promotional activities. The system uses computers, corresponding software and supporting security products to generate unique data, which is sent to customers through the mobile phone short message service provided by mobile communication companies. The data is the eCoupon number. Customers use this data to participate in promotions organized by commercial enterprises. The data generated by the system has the characteristics of uniqueness, confidentiality and anti-counterfeiting. The realization of the system involves methods and equipment for electronic password generation, data storage and processing, data and network security, and data transmission through the mobile phone short message system. However, this technology lacks the ability to control coupons. It can be found that this technology only sends coupons through an ordinary text message, so it cannot prevent the possibility that the user can obtain double benefits by forwarding the text message. Lacking the ability to control the number of times of use technically makes it possible for users to use one text message to obtain preferential prizes multiple times. Or an illegal user obtains preferential prizes by forging an identical short message after learning the content of the short message, thereby defrauding a real user before the real user. In addition, ordinary text messages cannot be used to control users on the use time of coupons. Users may cause unnecessary disputes if they do not know the valid time of coupons.

Also found in the search: Chinese patent application number: 01803917.0, publication number: CN1395709, name: method and system for receiving, storing and processing electronic coupons with mobile phones or personal digital assistants. The technology states: It relates to a method for receiving, storing and processing electronic coupons for consumers with mobile phones or personal digital assistants, hereinafter referred to as mobile tools, including data exchange with payment terminals during purchase operations The means of exchanging, according to the offer corresponding to the discounted electronic coupon, receives and stores at least one electronic coupon in the memory of the mobile tool, reads the code of the purchased commodity at the payment terminal, and transmits to the payment terminal the code stored in the mobile tool. Coupon list in or conversely, transmit to the mobile tool a list of purchased items read at the payment terminal, compare the coupon list with the list of purchased items, and if one or more items When it is recognized that one or more coupons exist for the item(s), the discounted price corresponding to the coupon is automatically subtracted from the total price purchased. This technical patent also lacks control over the time and number of uses of coupons. There are loopholes of repeated use or expired use.

Contents of the invention

The purpose of the invention is to overcome the deficiencies in the prior art, fully utilized the time control and security control of the STK card and the anti-forgery of the data short message, propose a kind of method utilizing the data short message and the STK menu to realize the short message coupon, and then The real discount content is displayed through the STK card menu, and the STK card can also control the use of the coupon through measures such as system time and counters. It makes up for the defects of anti-counterfeiting, no time control, and unable to verify the usage of users that cannot be realized by existing SMS coupons, and can design more and more suitable preferential services for users.

The present invention is realized through the following technical solutions. The present invention utilizes data short messages to realize encrypted distribution and downloading, and utilizes the built-in menu structure of the STK card so that the recipient can use but cannot modify or forward the coupon. The use of coupons can be controlled by the time or the number of times of use, and information such as the signature of the merchant can also be added to provide a safer distribution channel and allow users to enjoy more preferential information.

Specifically include the following steps:

①After the user initiates the registration process, the server first completes the key interaction with the user's STK card to obtain the user's unique communication key;

The key is used for future SMS encryption measures. After the key exchange is completed, the STK card can actually download the coupon.

②The user uses the STK card menu to search for coupons, or searches for coupons on the webpage, selects the appropriate coupon and sends a download request;

③After receiving the request, the server sends the coupon to the mobile phone via text message, and the coupon is downloaded to the STK card with the encrypted data text message as the carrier;

④The STK card receives the encrypted coupon, and first decrypts and verifies it. After confirmation, store the coupon in the coupon list;

⑤Users can see the downloaded coupons in the STK card menu, and select the coupons to use;

⑥The server sends coupons after setting different usage types for coupons according to user requirements.

The use type mentioned refers to: Coupons can be divided into the following categories:

a. Ordinary type, after the coupon is downloaded, it will be directly listed in the menu, and the user can use the coupon directly.

b. Requires activation, which means that this type of coupon will not be displayed after downloading, and the user must send a confirmation message before activating the coupon.

c. Verification-required type refers to the need to enter a confirmation password when using this type of coupon, and only the person who has the password can open the coupon. The merchant controls this password, which can prevent forgery to the greatest extent.

d. Need to use the confirmation type, which means that after using this type of coupon, the STK card will prompt the user to send a confirmation of the use, so as to facilitate the statistics of the usage of the commodity inspection.

e. Comprehensive type refers to the type in which all the above types can be superimposed on each other to obtain more performances.

After the coupon is used by the user, the STK card will automatically decrement the counter of the coupon by one, and when the counter reaches 0, the coupon will be automatically deleted.

The coupon has an expiry date, and the STK card automatically obtains the current time from the network, and checks all coupons at the same time; the STK card regularly checks the time of the coupon, and if it is found that the valid time of the coupon has expired , the coupon will be automatically deleted.

After the user uses the coupon, the STK card will also prompt the user to send a confirmation text message, which can provide the merchant with first-hand statistics.

The user uses the STK card, and the server sends the coupon to the STK card through an encrypted short message. After the verification is passed, the STK card uses a menu to list the coupon for the user to use.

Compared with the prior art, the remarkable effect of the present invention is that the present invention is obviously anti-counterfeiting, and has changed the defect that arbitrarily modifying short messages cannot guarantee the interests of merchants. The invention uses encrypted short messages and uses menu storage, which cannot be forged and disseminated, and obviously has anti-dissemination properties, which changes the defect that the prior art cannot control dissemination and users disseminate short messages to others for use at will. The invention automatically filters expired coupons according to the network time, and overcomes the disadvantage of no use time control in the prior art. The security of the merchants is guaranteed, so that the merchants have a greater ability to provide more substantial discounts, promote a prosperous market and benefit consumers.

Detailed ways

The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.

As shown in Figure 1, the specific steps of this embodiment are:

Steps ①, ②, and ③ are the registration process

Step ②: When the user enters the menu for the first time, the STK card will send a text message to the server of the service operator to initiate a registration request

In order to avoid security problems, the SMS discount card must be activated before it can be used normally.

When the user enters the menu for the first time, he or she will be prompted whether to send the registration information. After confirming the information, the STK card will send a short message to the server of the service operator to initiate the registration process.

The STK card and the server exchange keys through SMS. The key is randomly generated. After the exchange is successful, the STK card and the server each permanently save the key for future encryption and decryption of SMS coupons. After the key exchange is successful, the server sends a successful registration message to the user.

After the STK card terminal receives the registration confirmation message, it needs to remind the user that the registration is successful.

Step ④: Search

The search function allows users to find some preferential services they like through certain categories or keywords. The search can be performed through the webpage or through the SIM card menu. This document only defines the process description for searching through the STK card.

category search

The user selects the category of coupons he wants to search in the STK card menu, and the STK card sends the selection result to the server through a search message.

The server returns the search results to the STK card, and a maximum of 10 results are returned at a time. If the relevant discount information stored on the server is more than 10, a "continue" parameter is returned at the same time.

After receiving the search results, the STK card saves them in the file, and at the same time reminds the user that the search results have been received. The user enters the search result menu to view. If any coupon is selected, it will enter the download process.

If the user chooses "Continue", then upload the classification search again.

Keyword search The user enters the keyword to be searched in the STK card menu, and the STK card sends the selection result to the server through a search message.

The server returns the search results to the STK card, and a maximum of 10 results are returned at a time. If the relevant discount information stored on the server is more than 10, a "continue" parameter is returned at the same time.

After receiving the search results, the STK card saves them in the file, and at the same time reminds the user that the search results have been received. The user enters the search result menu to view. If any coupon is selected, it will enter the download process.

If the user chooses "Continue", then upload the classification search again.

Step 5: Download

A coupon may be downloaded via one or more text messages.

Each coupon contains multiple functional modules. After receiving the coupon, the STK card should make a correct processing process according to each command module.

After the coupon is downloaded, the STK card should store the coupon in its own storage area, and display it to the user according to the conditions after the user enters the menu next time.

As shown in Figure 2, step ⑥⑦⑧ is the process for users to use coupons through the menu:

Step ⑥: STK card updates the menu after receiving the coupon;

Step 7: The user uses the coupon;

Step 8: The user displays the coupon to the merchant for confirmation;

Step 9: coupon control;

There are several types of controls for coupons:

Time control: Every time the SIM card updates the coupon list, it checks the valid time of the coupon and the current system time, and deletes it from the list if an expired coupon is found.

Number of times control: After each coupon is used, the remaining usage times will be reduced by 1, and when the remaining times reach 0, the coupon will be automatically deleted.

Access confirmation: In order to prevent users from opening a coupon at will, before opening, the STK card will prompt the user whether to use the coupon, and continue to use it after confirming that it is correct.

Access condition control: Some coupons provide a higher level of preferential measures, so the provider can use password protection for this coupon, and users cannot open the coupon without knowing the password to obtain the accurate text content, so as to prevent forgery.

User Manual Deletion: Users can delete coupons that they deem useless at any time.

Step 10: Use confirmation.

Certain coupons can be set to require user confirmation. After using this coupon, the user will be prompted whether to send a confirmation message to the server, and then the server will count the usage.
