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.

Abstract: A method for managing handover procedure in a radio access network (RAN) includes initiating, by a source base station, a handover procedure for a first user equipment with a target base station, wherein the first user equipment is connected to the source base station; identifying, by the source base station, a second user equipment that functions as a relay device, for relaying data related to the first user equipment from the source base station to the first user equipment during the handover procedure; establishing, by the source base station, a first connection between the identified second user equipment and the first user equipment; transmitting, by the source base station, buffered data corresponding to the first user equipment, to the target base station; transmitting, by the source base station, at least one block of data from the buffered data to the first user equipment, via the second user equipment, during the handover procedure for the first user equipment from the source base station to the target base station; and disconnecting, by the source base station, the established first connection between the second user equipment and the first user equipment, upon receiving a sequence number (SN) status request message from the target base station.

Abstract: A method for content management in a cellular network is provided. The method includes receiving, by an application server, a content request including a file identity from a User Equipment (UE), performing, upon receiving the content request, by the application server, at least one action associated with content caching, content retrieval, and content deletion, assigning, by the application server, one or more assisting parameters in a header of an Internet Protocol (IP) packet, based on the at least one performed action, and assisting, by the application server, at least one of a User Plane Function (UPF) device, and a Packet Data Convergence Protocol (PDCP) device of the cellular network to manage content, based on the one or more assigned assisting parameters.

Abstract: A pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Method and/or electronic device for managing a software upgrade of a network element of a random access network (RAN) by a management data analytics service (MDAS) producer is provided. The method comprises: receiving a request related to an optimal time for the software upgrade of the network element in the RAN, from a MDAS consumer; identifying information related to a dedicated radio bearer (DRB); identifying information related to the optimal time for the software upgrade of the network element based on the information related to the DBR; and transmitting a report including the information related to the optimal time for the software upgrade of the network element.

Abstract: Provided is a method for optimizing radio resource for Ultra-Reliable Low Latency Communication services in a Dual Connectivity technology. The method includes: receiving DownLink (DL) data by a UE using a first Radio Access Technology (RAT) from a base station; transmitting a first Acknowledgement (ACK) signal using the first RAT to the base station based on the DL data being successfully received; updating a Mapping Table Sequence Number of the DL data in a Mapping Table by the UE, based on the DL data being successfully received by the UE using the first RAT; checking the Mapping Table by the UE upon detecting an error in the received DL data using a second RAT; and sending a second ACK signal to the base station using the second RAT of the UE based on the Mapping Table Sequence Number of the DL data being found in the Mapping Table.
