1. A method of uniquely identifying a user equipment (UE) connected to a radio access network (RAN), comprising:
providing a radio access network intelligent controller (RIC) component associated with the RAN;
configuring, by a packet data convergence protocol (PDCP) layer, a default data radio bearer (DRB) for the UE to maintain Internet Protocol (I) Protocol Data Unit (PDU) connectivity with the RAN; and
using, by the RIC, one of NG uplink (UL) user plane (UP) Transport Layer Information or S1 UL UP Transport Layer Information of the default DRB for uniquely identifying the UE for the entire time the UE is connected to the RAN.
