Abstract

Describe dimensioning methods for a set of circuit groups handling multi-slot bearer services which consist of first-choice groups and an overflow group to which overflow traffic from the first-choice groups are offered. It provides example methods for calculating peakedness of the overflow traffic and example methods for calculating individual call blocking probabilities of the overflow group.
