Method and apparatus for power management in a wireless communication system

An apparatus for power management in a wireless communication system, the apparatus comprising:

• a transceiver;
• a memory;
• and
• at least one processor coupled to the transceiver and the memory, wherein the at least one processor is configured to:
• measure network resource utilization levels for a plurality of virtual network functions (VNFs) over a time period based on at least one network parameter,
• determine a behavioral pattern of the network resource utilization levels based on a predictive analysis of the measured network resource utilization levels,
• forecast 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
• adjust CPU core frequencies of a network server based on the forecasted lean workload time interval.
