Abstract

A system and method for buying goods and billing agency using short message service are disclosed. If a purchaser transmits goods information to a mobile communication service system using short message service of a mobile phone, the mobile communication service system generates a certification code corresponding to the goods information and transmits it to a shopping mall server and the mobile phone. Then, the shopping mall server and the mobile phone exchange messages and run mutual authentication. Thereby, system construction expense for selling goods and service is decreased, purchasing procedure is simple, and the safe purchase can be done by mutual authentication using the certification code.

Claims

1. A method of buying goods and billing therefor using short message service (SMS) in a mobile telecommunication network, the method comprising:

receiving information regarding goods which a buyer requested to buy from a mobile terminal, wherein the goods information includes at least a predetermined goods code classified according to goods and/or services associated with a shopping mall server;

generating, at a mobile telecommunication server, a primitive authentication code corresponding to the goods information in order to approve the mutual authentication between the buyer and the shopping mall server;

storing, at the mobile telecommunication server, the primitive authentication code;

partitioning, at the mobile telecommunication server, the stored primitive authentication code into a first authentication code and a second authentication code with the use of a predetermined partition algorithm;

transmitting the first authentication code to the mobile terminal through a SMS center (SMSC);

generating purchase information which includes the goods information and the second authentication code;

transmitting the purchase information to the shopping mall server;

receiving, at the mobile telecommunication server, the first and second authentication codes from the mobile terminal and shopping mall server, respectively;

synthesizing, at the mobile telecommunications server, the received first and second authentication codes with the use of a predetermined synthesis algorithm to generate a synthesized authentication code;

determining, at the mobile telecommunication server, whether or not the synthesized authentication code is identical to the primitive authentication code;

receiving, at the mobile telecommunication server, a payment option from the mobile terminal, wherein the payment option is one of the following;

i) payment via the buyer'"'"'s mobile phone fees, ii) credit card payment, iii) account transfer, and iv) an online payment; and

billing, based on the received payment option for the buyer'"'"'s goods purchase when the synthesized authentication code is identical to the primitive authentication code.

2. The method of claim 1, further comprising:

transmitting a transaction canceling message to the mobile terminal or the shopping mall server through the SMSC when the synthesized authentication code is not identical to the primitive authentication code;

billing for the buyer'"'"'s goods purchase and transmitting a billing completion message to the shopping mall server when the synthesized authentication code is identical to the primitive authentication code; and

transmitting a transaction completion message to the mobile terminal through the SMSC.

3. The method of claim 1, wherein the billing comprises:

generating transaction details corresponding to the goods for the buyer to buy wherein the transaction details include at least the goods code and the goods price; and

transmitting the transaction details to a billing system for billing on a mobile communication service.

4. The method of claim 1, wherein the transmitting of the first authentication code and the transmitting of the purchase information are performed before the billing.
