1. A method for power management in a wireless communication system, the method comprising:
measuring network resource utilization levels for a plurality of virtual network functions (VNFs) over a time period based on at least one network parameter;
determining a behavioral pattern of the network resource utilization levels based on a predictive analysis of the measured network resource utilization levels;
forecasting a lean workload time interval of the network resource utilization levels based on the determined behavioral pattern and current network resource utilization levels of the plurality of VNFs; and
adjusting central processing unit (CPU) core frequencies of a network server based on the forecasted lean workload time interval.
