<p>In an advanced intelligent network, a method of using a Service Control Point (22) for managing the overloading of calls, for example, from calling parties in LATA A (20) associated with Service Switching Points SSP 1 - SSP n to a single telephone number (operators) in LATA Z (24) associated with SSP m (40). The method enables Service Control Point (22) to service a small percentage of the time during measurement intervals in order to receive Termination Notification messages. The Service Control Point (22) then determines from the content of the Termination Notification messages for each measurement interval, the rate of attempted calls and the fraction of the total calls that were incomplete (i.e., erroneous or received a busy signal) for a telephone number n, and invokes Automatic Code Gapping for the number n where both the attempted call rate and the incomplete calls exceed a predetermined threshold. If the threshold continues to be exceeded in subsequent measurement intervals, a larger gap interval for the Automatic Code Gapping can be set, and the process repeated until the proper gap is found.</p> |
