1. A method of operating a user equipment (UE) in a wireless communication system, the method comprising:
receiving a request for UE mobility history information from a network node;
generating a UE mobility history report; and
transmitting the UE mobility history report to the network node,
wherein the UE mobility history report comprises at least one of:
a number of transitions between an inactive state and a connected state for each cell included in the UE mobility history report;
a carrier frequency of each cell included in the UE mobility history report; and
information based on whether the network node is a secondary node or a master node, and
wherein the UE mobility history report comprises a mobility history for a Primary Secondary Cell (PSCell) included in a Primary Cell (PCell) mobility history log.
