A system and method for minimizing interference for mobile devices operating in a communication network that includes a centralized controller and a number of femtocells, each femtocell including a base station. The method calculates a power assignment priority for each femtocell, and determines a priority order of the femtocells, the priority order based on the power assignment priority calculated for each femtocell. The method calculates a power to assign to the base station for each femtocell based on the priority order. The method allocates a first portion of the power assigned to the base station for each femtocell as required for real-time traffic, and a second portion of the power assigned to the base station for each femtocell as required for non-real-time traffic.
