Description

METHOD AND SYSTEM FOR PROVIDING A MOBILE SHOPPING CART SERVICE
Technical Field
The present invention relates, in general, to a system and method for providing a mobile shopping cart service and, more particularly, to a service method and system for transmitting helpful information to the mobile communication terminal of a user when purchasing products. The information is based on product codes transmitted by the user, when the user promptly registers products of interest and transmits the product codes to a remote server using the mobile communication terminal while performing shopping online or offline.
Background Art
With the development of the Internet and the information and communication industry, electronic commerce (e-commerce) using the Internet, particularly the purchase of products using Internet shopping malls, has become part of life and is being actively conducted.
FIG. 1 is a block diagram illustrating the entire construction of a prior art e-commerce system.
The member 10 of an e-commerce website accesses a web server 20 in which the e- commerce system has been constructed and orders a product, and a nonmember 11 orders a product through a Public Switched Telephone Network (PSTN) 13, thus ultimately purchasing products from an e-commerce company that has constructed the web server 20. Order data, which is created based on the orders, is processed in a database (DB) server 30 and transmitted to a distribution center 40, so that the ordered products are delivered to the persons that ordered the products. FIG. 2 is a diagram illustrating the construction of the DB server 30 of FIG. 1. The DB server 30 includes a product data unit 31 for classifying products that are provided by cooperating companies, into categories, managing a list of products, and constructing a logistic statistics DB; a customer data unit 33 for storing and managing the basic personal information, contact information, number of orders, details of the orders and degrees of use of member users; an address data unit 35 for storing information about orderers and delivery addresses so that products can be delivered to the addresses desired by the members or nonmembers who ordered the products, and allowing postal codes and the body of the addresses to be automatically entered so that users can easily input addresses; a bonus-point data unit 37 for assigning predetermined bonus points at the time of placing orders and storing and analyzing bonus-point data; and a statistical data unit 39 for collecting statistics of orders for products depending on the types of products and implementing target marketing for individual customers.
FIG. 3 is a flowchart illustrating the entire flow of the prior art e-commerce. When a user accesses a web server at step Sl, the e-commerce system examines whether the user has subscribed as a member at step S2, and invites the user to use the e-commerce system only after subscribing (step S2!) by introducing a membership subscription procedure to the user if the user is not a member. If the user is a member, the user searches a product list, which is classified according to the types of products, for a desired product at step S3, and makes a purchase decision by clicking on an iconized product if there is the desired product at step S4. The user enters a delivery address after making the purchase decision at step S55 in which case the ordered product is allowed to be received at locations other than a home address and a job address that were entered at the time of membership subscription. Meanwhile, when a general user 11, who is a member or a nonmember, desires to place an order via telephone rather than the Internet using a Personal Computer (PC)5 the general user 11 places an order for a product through a CTT server for performing an automatic address entering function via a PSTN 13. When the order for the product is placed through the above-described procedure, data, including the details of the order, membership information and a delivery address, is processed into delivery data, including the name of the product to be delivered, the orderer of the product and the price of the product, and is transmitted to a call server. The call server then selects a distribution center adjacent to the location to which the product is to be delivered and transmits the delivery data to the distribution center at step S7. The delivery data is transmitted to a fixed distribution center, such as a warehouse, or a mobile distribution center, and the distribution center delivers the product according to the transmitted delivery data, so that the product orderer or product receiver can receive the product at step S8. Once the product is safely received, the orderer or receiver pays for the product at step S9. When the payment is completed, a payment result is transmitted to the call server and stored in a DB at step SlO. However, the prior art e-commerce system is problematic in that access to respective shopping malls must be gained at the time of making a purchase decision while containing products of interest in an on-line shopping cart because the products of different shopping malls cannot be contained in the same shopping cart in the case where shopping has been performed in a plurality of different shopping malls. Furthermore, in order to make a purchase decision for a product after finding a product in an off-line shopping mall, information about the product must be memorized or written down. Moreover, when a plurality of on-line or off-line shopping malls sells the same product, it is inconvenient to compare the prices of the product between the different shopping malls.
Summary of the Invention
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a method and system for providing a mobile shopping cart service, in which a user can easily construct a single shopping cart simply by transmitting product codes, even if the user selects a product at a different on-line shopping mall after selecting a product to be purchased at a specific website, and information helpful to a product purchase decision is transmitted to the user based on the product code.

Meanwhile, when bar code is utilized, the product recognition unit 59 is a barcode reader that reads a bar code indicated on the outside of a product or the panel of a display stand. However, when the user performs shopping using an on-line shopping mall, a product code must be inputted by pressing the buttons of a keypad using the input unit 52 of the mobile communication terminal. The message creation unit 57 creates a message by adding user information, such as the service ID of the user or the Mobile Identification Number (MUST) of the mobile communication terminals to the input product code, so as to transmit the message to the cart server 70. This is performed to enable the cart server 70 to manage product code information for each user. Furthermore;, the message creation unit 57 is a means for preparing criteria for creating product purchase information when the user requests a product purchase information request message from the cart server 70 in a pull fashion. This is described in detail in a later description of the price comparison unit 73 of FIG.7.
The purchase request unit 58 functions to transmit a product purchase request message to the cart server 70 when the user attempts to purchase a product using the mobile communication terminal 50. The product purchase request message includes information about a credit card, a bank account or an e-money account
FIG.6 is a diagram illustrating the construction of the fields of a product code 80 according to the present invention.
