Abstract
A software process setting time limits for telephone calls so that a subscriber's account balance is not exceeded. The method estimates the time when the subscriber's balance will expire by using total charges for all calls per second. The process accounts for time already paid for, reserving the minimum continuation time for adding a new call, reserving time for all calls up to the latest paid for time, dividing the remaining balance by total charges per second to estimate the time left before the subscriber's balance reaches zero, an setting the time limit for each call accordingly.
