1. A method performed by an operations, administration and maintenance (OAM) function node for closed loop service level specification (SLS) assurance, the method comprising:
transmitting, to a user equipment (UE) via a radio access network (RAN) node, quality of experience (QoE) measurement configuration for the SLS assurance for the UE including a reporting criterion, a reporting format, service type, and information indicating whether the UE should report;
obtaining, from a data analytics function entity including a management data analytics function (MDAF) node and a network data analytics function (NWDAF) node, a quality of experience (QoE) analytic result based on a quality of experience (QoE) measurement reporting which is performed by the UE based on the reporting criterion, the reporting format, the service type, and the information indicating whether the UE should report;
adjusting a network configuration based on the QoE analytic result; and
autonomously repeating the obtaining and adjusting in a closed loop in the OAM function node until the SLS is assured,
wherein the service type is defined to include a value “Virtual Reality (VR) services”.
 
2. A method performed by a user equipment (UE) for closed loop service level specification (SLS) assurance, the method comprising:
receiving, from an operations, administration and maintenance (OAM) function node via a radio access network (RAN) node, a quality of experience (QoE) measurement configuration for the SLS assurance including a reporting criterion, a reporting format, a service type, and information indicating whether the UE should report;
performing a quality of experience (QoE) measurement reporting based on the reporting criterion, the reporting format, the service type, and the information indicating whether the UE should report; and
receiving an adjusted network configuration based on a quality of experience (QoE) analytic result based on the QoE measurement reporting, wherein:
the QoE analytic result is received from a data analytics function entity including a management data analytics function (MDAF) node and a network data analytics function (NWDAF) node,
the performing and the receiving is autonomously repeated by a closed loop in the OAM function node until the SLS is assured, and
the service type is defined to include a value “Virtual Reality (VR) services”.
 
4. An operations, administration and maintenance (OAM) function node for closed loop service level specification (SLS) assurance, the OAM function node comprising:
at least one memory storing instructions; and
at least one processor configured to process the instructions to:
transmit, to a user equipment (UE) via a radio access network (RAN) node, a quality of experience (QoE) measurement configuration for the SLS assurance for the UE including a reporting criterion, a reporting format, service type, and information indicating whether the UE should report;
obtain, from a data analytics function entity including a management data analytics function (MDAF) node and a network data analytics function (NWDAF) node, a quality of experience (QoE) analytics result based on a quality of experience (QoE) measurement reporting which is performed by the UE based on the reporting criterion, the reporting format, the service type, and the information indicating whether the UE should report;
adjust a network configuration based on the QoE analytics result; and
autonomously repeat the obtaining and adjusting in a closed loop in the OAM function node until the SLS is assured,
wherein the service type is defined to include a value “Virtual Reality (VR) services”.
 
5. A user equipment (UE) for closed loop service level specification (SLS) assurance, the UE comprising:
at least one memory storing instructions; and
at least one processor configured to process the instructions to:
receive, from an operations, administration and maintenance (OAM) function node via a radio access network (RAN) node, a quality of experience (QoE) measurement configuration for the SLS assurance including a reporting criterion, a reporting format, service type, and information indicating whether the UE should report;
perform a quality of experience (QoE) measurement reporting based on the reporting criterion, the reporting format, the service type, and the information indicating whether the UE should report; and
receive an adjusted network configuration based on a quality of experience (QoE) analytic result based on the QoE measurement reporting, wherein
the QoE analytic result is received from a data analytics function entity including a management data analytics function (MDAF) node and a network data analytics function (NWDAF) node,
wherein the performing and the receiving is autonomously repeated by a closed loop in the OAM function node until the SLS is assured, and
wherein the service type is defined to include a value “Virtual Reality (VR) services”.
