Apparatus and method for guaranteeing service level agreement item of terminal in wireless communication system

A method performed by an open radio access network distributed unit (O-DU) in a wireless communication system, the method comprising:

• receiving, from a radio access network intelligent controller (RIC), a subscription request message including configuration information for reporting whether a service level agreement is satisfied for each terminal or terminal group;
• transmitting, to the RIC through an E2 interface, an indication message including information on whether the service level agreement is satisfied;
• and
• receiving, from the RIC, a control message including scheduling information configured based on the indication message.

A radio access network intelligent controller (RIC) in a wireless communication system, the RIC comprising:

• a transceiver;
• at least one processor;
• and
• memory storing instructions that, when executed by the at least one processor, cause the RIC to:
• transmit, to an open radio access network distributed unit (O-DU), a subscription request message including configuration information for reporting whether a service level agreement is satisfied for each terminal or terminal group,
• receive, from the O-DU through an E2 interface, an indication message including information on whether the service level agreement is satisfied, and
• transmit, to the O-DU, a control message including scheduling information configured based on the indication message.
