Abstract

According to teachings herein, a telecommunication network manages licensed transaction capacity for a licensed service provided by the network, based on dynamically adjusting the allocation of licensed capacity across multiple traffic processors providing the service. Reallocation of licensed capacity is performed with respect to the actual traffic loads at the traffic processors. For example, licensed capacity at a lightly loaded traffic processor is decreased and licensed capacity is correspondingly increased at a heavily loaded traffic processor. This dynamic redistribution of licensed capacity to reflect variations in the distribution of traffic loads across the traffic processors provides for more efficient utilization of the licensed transaction capacity.
