## Abstract

A method and an apparatus for identifying a user in a radio access network (RAN), and a first node in the wireless communication system are provided. The method includes identifying a unique identifier of a UE, identifying a radio access network (RAN) UE identifier of the UE, and transmitting information related to a mapping relation between the RAN UE identifier and the unique identifier of the UE to a second node, based on the unique identifier of the UE.

The method of claim 1, further comprising:
transmitting, to an O-RAN central unit-user plane (O-CU-UP), a bearer context setup request message including the RAN UE ID.

### Claim 5 (depends on 1)

The method of claim 1,
wherein the UE ID is stored in the RIC, and
wherein a list of UE IDs based on the stored UE ID is transmitted for policy information from the RIC to a non-real time RAN intelligent controller (NRT-RIC).

### Claim 6

A method of a near-real time RAN intelligent controller (RIC) in a communication system, the method comprising:
receiving, from an open radio access network (O-RAN) central unit-control plane (O-CU-CP), an indication message for a report, the indication message including a user equipment identity (UE ID) and information associated with a UE per the UE ID; and
storing the received UE ID,
wherein the UE ID comprises a radio access network (RAN) UE ID for identifying the UE uniquely for E1 interface.
