Title: Flow control of authentication triplet request for reducing usage time of a central processor

Abstract: A method of requesting authentication triplets as a function of CPU processing time at a MSC. The MSC requests a new set of authentication triplets from an HLR as a function of how busy the MSC CPU is. During the least busy periods of time, the MSC requests a new set of triplets often and discards some triplets, while during medium busy periods of time the MSC requests a new set of triplets when only, for instance, 2 triplets remain. During the busy periods of time, the MSC only requests a new set of 5 triplets from the HLR when no triplets remain. The present invention, in effect, postpones non-critical work to non busy periods of time when the MSC has more spare processing power, thereby increasing the capacity of the MSC to support traffic during busy periods.
