scope:

The present document 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.

The present document also provides recommendations for enhancements to the NFV architectural framework and its functionality, aiming to provide further support for vRAN use cases.
