Wireless communication terminal suspending interrupt during RF payment and method thereof

1. A wireless communication terminal for mobile commerce that can suspend events during Radio Frequency (RF) payment, comprising:

a storage for storing a pre-established authentication number;

a keypad for receiving a mobile commerce request and an authentication number;

a controller for requesting authentication for the mobile commerce to an authenticator in response to the mobile commerce request, analyzing an authentication response message from the authenticator, operating a timer for a predetermined time during the mobile commerce, setting up a flag so as to suspend events generated while the flag is set up and suspending events generated while performing RF payment;

the authenticator for authenticating the mobile commerce function by comparing the mobile commerce request from the controller, the authentication number inputted through the keypad, and the pre-established authentication number;

a radio frequency (RF) antenna for transmitting/receiving an RF signal for a function of the mobile commerce under the control of the controller; and

a display for displaying the process of mobile commerce under the control of the controller.

2. The wireless communication terminal for mobile commerce as recited in claim 1 , wherein the controller transmits the mobile commerce request and a message for inquiring the payment type set up in the wireless communication terminal to the authenticator and recognizes the current payment type by analyzing a response message from the authenticator.

3. The wireless communication terminal for mobile commerce as recited in claim 1 , wherein the RF antenna is positioned in a battery of the wireless communication terminal.

4. The wireless communication terminal for mobile commerce as recited in claim 1 , wherein the authenticator is an integrated circuit (IC) chip storing credit information and private information of a user.

5. A method for suspending events in a wireless communication terminal during Radio Frequency (RF) payment, comprising the steps of:

a) transmitting a mobile commerce request;

b) transmitting a response message containing information on a payment method set up in the wireless communication terminal in response to the request;

c) checking the current payment method by analyzing the response message;

d) confirming that the current payment method is RF method and receiving an authentication number for acquiring authentication to operate the mobile commerce in the RF method;

e) if the authentication based on the authentication number is successful, inactivating the authenticator;

f) operating a timer for a predetermined time and setting up a flag so as to suspend events generated while the flag is set up; and

g) suspending events generated while performing RF payment.
