First, let's talk about electronic credit transactions that start with mobile phones.

First, the electronic credit transaction starting from the mobile phone is determined by the user of the mobile phone 1 by determining the ECS_TYPE field value and the ECS_SUBTYPE according to the type of electronic credit transaction desired, and then creating a data burst message as shown in FIG. 2 or 4. The channel also transmits a message on the reverse traffic channel. At this time, BURST_TYPE uses a value set for electronic credit transaction from 000101 to 111110. Then put the password you know only in the CHARi field. At this time, the information required for the electronic credit transaction is put in the CHARi field according to the format.

Next, upon receiving the data burst message transmitted from the base station 2, it is determined whether the BURST_TYPE is a value set for electronic credit transaction, and the ECS_TYPE and ECS_SUBTYPE fields are examined and processed as follows.

That is, if the ECS_TYPE is '0000' (Confirm), the request is successfully processed. At this time, the characters of the CHARi field are displayed on the screen and the electronic credit transaction is completed.

However, if the ECS_TYPE is '0001' (Information), the character of the CHARi field is displayed on the screen, the electronic credit transaction is continued, and the base station 2 continuously waits for a response.

If the ECS_TYPE is '0010' (Reject), the electronic credit transaction is terminated because the request is rejected. At this time, the ECS_SUBTYPE field is examined to display an appropriate string corresponding to the cause of rejection on the screen.

Next, the electronic credit transaction starting at the base station 2 will be described.

The electronic credit transaction starting from the base station 2 receives a data burst message transmitted from the base station 2 to the mobile phone 1 to determine whether the burst type BURST_TYPE is a value set for the electronic credit transaction. After checking the ECS_TYPE and ECS_SUBTYPE fields, the necessary information and password are put into the CHARi field, the corresponding ECS_TYPE and ECS_SUBTYPE fields are put, and the data burst message is transmitted to the base station 2 again.

Upon receiving the data burst message transmitted from the base station, it is determined whether the BURST_TYPE is set for electronic credit transaction, and the ECS_TYPE and ECS_SUBTYPE fields are examined and processed as follows.

That is, if the ECS_TYPE is '0000' (Confirm), the request is successfully processed. At this time, the characters of the CHARi field are displayed on the screen and the electronic credit transaction is completed.

However, if the ECS_TYPE is '0001' (Information), it simply displays the characters of the CHARi field on the screen of the mobile phone 1, continues the electronic credit transaction, and waits for the response of the base station 2 continuously.

If the ECS-TYPE is '0010' (Reject), since the request is rejected, the electronic credit transaction ends. At this time, the ECS_SUBTYPE field is examined to display an appropriate character string corresponding to the cause of rejection on the screen of the mobile phone 1.

In other words, different types of electronic credit transactions are possible using the ECS_TYPE and ECS_SUBTYPE fields.

For example, if you want to pay for your purchases, you can use ECS_TYPE and ECS_SUBTYPE to get a payment number: The following is an example of use for FIG.

Takes the password entered by the user and sets the ECS_TYPE and ECS_SUBTYPE as follows, and creates and sends a data burst message requesting the payment number.

ECS_TYPE: Request.

ECS_SUBTYPE: Billing Number Request.

4 CHARi passwords.

When the base station receives the data burst message, the base station retrieves the user's credit information, obtains the payment number from the bank or the credit information database, sets the ECS_TYPE and ECS_SUBTYPE as follows, and sends a response to the mobile phone 1 (see FIG. 7). )

ECS_TYPE: '0000' (Confirm).

ECS_SUBTYPE: Not used.

Several CHARi: Billing Numbers.

The mobile phone 1 displays the characters of CHARi on the screen and informs the clerk.

If the user's password of the mobile phone 1 is incorrect or a bad credit trader, it can be set as follows.

ECS_TYPE: '0010' (Reject).

ECS_SUBTYPE: Password mismatch.

In the electronic commerce method using the mobile phone according to the second embodiment of the present invention, when the mobile phone 1 receives the electronic credit transaction request from the base station 2, the mobile phone 1 displays the type of electronic credit transaction (S11). For example, when the vehicle passes near the highway toll settlement, the following electronic credit transaction request is received from the base station 2 installed in the toll settlement. At this time, ECS_TYPE, ECS_SUBTYPE, and CHARi may be set as follows.

ECS_TYPE: '1010' (Request automatic billing).

ECS_SUBTYPE: Not used.

Several CHARi: "Seoul Daejeon section", "3,500 won".

The terminal displays all the characters of the CHARi, and allows the user to select "OK" or "CANCEL" (S12).

When the user selects "OK", the user receives the password, creates and transmits a data burst message as shown below using the vehicle number previously stored, and waits for a response from the base station 2 (S13). ).

ECS_TYPE: '0010' (Automatic Billing Response).

ECS_SUBTYPE: OK.

Several CHARi: password, vehicle number.

After checking the password, the base station 2 responds to the response of the mobile phone 1 with 'Confirm', 'Reject', or 'Information'.

Then check the received payment number, and tells the clerk the payment number (S14).

Subsequently, the clerk enters a payment number into a point of sale information management system (POS) terminal and completes an electronic credit transaction by inputting a price (3500 won) to be paid by the customer (S16).
