摘要
A wireless prepaid payphone system provides simple and efficient payphone service in a wireless communications network. A payphone interface is added to a prepaid server of the wireless network, enabling real-time communication between the prepaid server and a payphone application running in a wireless/mobile handset. This real-time communication allows the payphone application to automatically and accurately calculate the amount to be charged for each call, as well as keeping track of an accumulated total for all the calls made. The total price/cost for a made call and the accumulated price/cost for all the calls made are displayed on the handset for easy viewing. Additionally, a cost control application allows limits to be placed on the usage, as it relates to the cost incurred, of the wireless handset.
