NGMN would like to thank ETSI ISG NFV for the feedback with questions. NGMN 5G SBA program has discussed the questions and the answers are shown below ETSI ISG NFV Q1) In NGMN view, is a 3GPP NF Service deployed only as part of a VNF (e.g. Location service as part of AMF), or is a 3GPP NF Service expected to be deployed independently, as a single VNF? a. If the Service is deployed as part of a VNF, do you require that some (or all) LCM operations to be performed independently of the other 3GPP 5GC NF Services that are composing that VNF, or not? NGMN SBA Answer: NGMN expects that 3GPP NF Services can be deployed independently, as a single VNF. NGMN","secretary_remarks":"Moved to 7.1 session. This LS was postponed.

TSG SA plenary has agreed that voice service continuity from 5GS to UTRAN CS should be supported in Rel-16 excluding: - Voice continuity from GERAN\/UTRAN CS to 5GS - Voice continuity from 5GS to GERAN - Video service continuity between 5GS and GERAN\/UTRAN - IP address preservation for PS service when UE moves between 5GS and GERAN\/UTRAN - Service continuity between 5GS and CDMA2000. Accordingly, TSG SA plenary approved a new work item (see attachment) to introduce corresponding Stage 1 requirements in 3GPP TS 22.261.

The deliverable has been created by NGMN Mobile Network Operator-Partners. The document describes a service framework including service registration, service authorization, and service discovery. Service-based Architecture for 5G is designed in a forward-looking manner, such that the functionalities in 5G Core Network (CN) consist of services, the interface between Control Plane (CP) and User Plane (UP) should be Service Based Interface (SBI) and the Data Service should be used. The deployment aspects of SBA are explored along with the gap analysis and recommendations for related SDOs.
