Title	Network Functions Virtualisation (NFV) Release 5; Architectural Framework; Report on NFV support for virtualisation of RAN NFV4RAN_report
Scope and Field of Application	This revision of NFV-IFA 046 continues the study analysis of the feature of NFV support for vRAN. This edition will further profile ETSI NFV specified features and capabilities considering the most recent developments in normative and informative work performed in Release 4 and 5, including but not limited to: PaaS services management, automation in NFV, physical infrastructure management, network connectivity requirements for vRAN and certificate management. The scope of the former edition (v5.1.1) is summarized hereafter: GR NFV-IFA 046 analyses the NFV framework to determine how it can further support virtualised RAN (vRAN) use cases. Several key technical challenges are identified relevant to architectural, operational and management aspects, in case the NFV architectural framework is leveraged to support virtualisation of the RAN. For each technical challenge a detailed analysis is provided, together with a description of potential solutions. Potential gaps in ETSI NFV specifications are articulated and a comparison between the different potential solutions is also accommodated. In addition, an analysis of vRAN use cases from relevant specifications from other SDOs is performed, together with a mapping to the current NFV concepts supported by the NFV architectural framework. GR NFV-IFA 046 also provides recommendations for enhancements to the NFV architectural framework and its functionality, aiming to provide further support for vRAN use cases.
