Abstract: A system and method for call selection and migration in a NG-CU over NGRAN is disclosed. The system and method comprises a CP VNFC assigning a call initiated by a user to a source user plane VNFC. A management VNFC detects an overload traffic condition upon receiving the assigned call by the source user plane VNFC from the CP VNFC. The source user plane VNFC selects the call to be migrated with a higher migration preference value to another VNFC and signals CP VNFC to initiate call migration. The CP VNFC then migrates the selected call through at least one GTP tunnel to a target user plane VNFC. The source user plane VNFC then forwards the target user plane VNFC a request to handle complete trafficking of the migrated call.

Abstract: The disclosure is related to a method for power management in a wireless communication system. The method includes 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.
