Purpose: For information

Body: 1. Overall Description:
SA5 has cooperated with GSMA 5GJA on implementing NG.116 (v2.0) GST SLA attributes as network slice ServiceProfile attributes in the 3GPP Network Resource Model (NRM) (TS 28.541 clauses 6.3.3, 6.4.1) in the Rel-16 work item Management Aspects of 5G Service-Level Agreement. This work item has been finalised in Rel 16, and a continuing Rel-17 work item Enhancement of Management Aspects of 5G Service-Level Agreement (SP-200190) has been approved. In Rel-17, SA5 will continue working on implementing updated GST SLA attributes, as GSMA 5GJA will continue working on NG.116. 

In addition, SA5 will work on breaking down SLA requirements to NetworkSliceSubnet to update the SliceProfile in the 3GPP NRM, which can provide clear requirements to CN, RAN and TN (TS 28.541 clauses 6.3.4, 6.4.1).
