Apparatus and method for managing user equipment in wireless communication system

A method performed by a near-real time (RT) radio access network (RAN) intelligent controller (RIC) in a wireless communication system, the method comprising:

• transmitting, to a non-RT RIC, first information related to a user equipment (UE) identity obtained from an E2 node;
• and
• obtaining, from the non-RT RIC, an A1 policy message based on the first information and second information generated by a network exposure function (NEF) of a 5th generation (5G) core network (5GC), via an A1 interface,
• wherein the first information includes a general public subscription identifier (GPSI), an access and mobility management function (AMF) UE next generation application protocol identity (NGAP) identity (ID) related to the 5GC, and a globally unique AMF ID (GUAMI) related to the 5GC, and
• wherein the second information includes an AMF UE NGAP ID related to the 5GC and a GUAMI related to the 5GC.

An apparatus for performing a non-real time (RT) radio access network (RAN) intelligent controller (RIC) in a wireless communication system, the apparatus comprising:

• at least one transceiver;
• and
• at least one processor operably coupled with the at least one transceiver,
• wherein the at least one processor is configured to:
• obtain, from an E2 node, first information related to user equipment (UE) identity of an open (O)-RAN,
• obtain, from a network exposure function (NEF) of a 5th generation (5G) core network (5GC), second information related to the UE identity,
• generate an A1 policy message based on at least the first information and the second information, and
• transmit the A1 policy message to a near-RT RIC via at least an A1 interface,
• wherein the first information includes a general public subscription identifier (GPSI), an access and mobility management function (AMF) UE next generation application protocol identity (NGAP) ID related to the 5GC and a globally unique AMF ID (GUAMI) related to the 5GC, and
• wherein the second information includes an AMF UE NGAP ID related to the 5GC and a GUAMI related to the 5GC.
