A method and system determines an absolute Multicast-Broadcast Single Frequency Network (MBSFN) configuration based on a threshold. First saved radio resources and first wasted radio resources are calculated. The absolute MBSFN configuration is set as the final MBSFN configuration when the first saved radio resources are greater than or equal to the first wasted radio resources. When untrue, the absolute MBSFN configuration plus an adjacent cell pool is set as the final MBSFN configuration based on the final MBSFN configuration achieving a maximum value of second saved radio resources minus second wasted radio resources. When both of these conditions are untrue, the absolute MBSFN configuration minus an MBSFN cell pool is set as the final MBSFN configuration based on the final MBSFN configuration achieving a maximum value of third saved radio resources minus third wasted radio resources.
