Thereafter, the user accesses an intelligent network 106 that provides a service such as a collect call or a call service using a prepaid card / postpaid card / credit card through the phone 110 connected to the wireless termination device 120 according to the present invention. .

When the user uses the intelligent network service, the intelligent network 106 determines whether the user's service use satisfies the event condition set by the event server 140, and when the event condition is met, delivers a preset event entry to the user. When the user listens to the event entry and inputs predetermined information to enter the event, the intelligent network 106 transmits the event entry to the event server 140.

Accordingly, when the event server 140 processes the event and the user wins the event, the event server 140 delivers a preset event winning congratulation to the user, as well as a promised event bonus (e.g., call discount, free talk time, special coupon, etc.). ). For example, in case of an event bonus related to charging such as a call discount or free talk time, the intelligent network 106 is requested to adjust the charging, and the user is notified of the result. In the case of a discount coupon or a free coupon, etc., an event coupon is issued to the wireless terminal device 120 according to the present invention. Accordingly, the printer of the wireless terminal device 120 issues a coupon. If the event is not won, send the comfort message and proceed to the next step.

As described above, according to the present invention, after installing a wireless termination device that can be used by an unspecified number using a mobile communication network even in an environment where it is difficult to install a wired line such as a mountain wall or a military unit, a prepaid card is connected to a general multifunction telephone.
