Disclosed are a periodic payment system for service use fees and a control method thereof, and a service provider of the payment system and a control method thereof. The periodic payment system receiving information on credit of a subscriber from a payment information provider includes a payment acknowledgement server for determining whether or not a demanded payment is acknowledged based on the credit information of the subscriber provided by the payment information provider, and providing payment demand information to the payment information provider if it is determined that the demanded payment is acknowledged. The service provider demands a periodic fixed payment of the payment acknowledgement server irrespective of a payment application date when the subscriber applies for payment for the service use fee, and demands payment of an amount of money excluding an advance payment, which is overpaid on the payment application date, from a periodic fixed fee on a payment update date immediately after the payment application date, of the payment acknowledgement server. The payment acknowledgement server outputs a system error signal if a payment acknowledgement error occurs. Upon receiving the system error signal from the payment acknowledgement server on the payment update date, the service provider informs the subscriber of occurrence of an abnormality of payment acknowledgement. Accordingly, an ill-intentioned early secession of the subscriber from the service can be prevented and the subscriber is informed of an nonpayment due to a system error on a service fee payment.
