3. High Level Objectives for Casablanca:
Deployment of the hybrid 5G Radio Network (PNFs & VNFs)
Complete PNF Support
Platform Enhancements to Deploy Edge Virtual Radio Network Functions (e.g. CU)
Creation & Management of Radio Slice Segment within the deployed network
Focus initially on RAN Slices Using A Simple Model
Use complex services (composite, allotted resource, etc.) to manage (model, on-board, create, configure, monitor) the slices
Optimization of the deployed 5G network and the slices
Near-real Time Data Collection (e.g. streaming) and Edge Analytics to Support 5G Network Optimization
OOF enhancements for optimal placement of edge resources

5. A: 5G Radio Network Deployment Requirements
Description
Disaggregated 5G RAN consists of hybrid network elements (PNF and VNF) and will require a cloud infrastructure deployment at the edge. Beijing implemented the first phase of PNF discovery and instantiation. Our goal for Casablanca is expand on that work, include VNF deployment at the edge, and full integrated lifecycle management. Key enhancements needed are:
Expand PNF Radio Element Controller to Support Full Application level Configuration (+Ansible), allow various mobile network elements to be controlled from same controller persona created from CC-SDK
Add Lifecycle management functions to controller persona such as Assign, configure, deactivate, etc.
Support an integrated configuration design tool in SDC that can be used with any controller persona (next gen CDT)
Add support for PNF Software Management and Change management
Edge Cloud Support
Add needed support for deploying Mobility Virtual Network Elements (e.g. CU) at the Edge locations
Further automation of PnP Discovery for PNF
Rationale
Support for deploying and managing 5G mobility network is critically important for most ONAP members.

7. B: Radio Network Slice Management – ONAP Requirements
Description
Many providers are interested in using ONAP to manage the general concept of Slicing (Extending the cloud notion of sharing network/compute/storage to sharing network functions and Services implemented across PNFs & VNFs). 3GPP standards are still evolving and early versions are not expected to be available before June However, we would like to demonstrate these concepts in ONAP initially using a simple slice definition, creation, and management for 5G Radio Network. Slice segments supported and demonstrated in Casablanca will be limited to two simple slices, eMBB (enhance Mobile Broad Band) and URLLC (Ultra-Reliable, Low-latency Communications) in the RAN. Key enhancements needed are:
Enhance SDC to model & define slice segments for Radio network
Enhance SO Instantiate and lifecycle manage slice segments
Enhance A&AI to inventory and store state of slice segments
Integrated design (e.g. configuration and service designs)
Support Complex Service Modeling (e.g. service composition, nested allotted resources)
Define and instantiate monitoring and management of slice segments, slice instances and slice services
Rationale
(why R2?)
Typical carrier deployments will be complex enough to need support for nested / complex services, correlation across multiple elements - hence, these are critical functional requirements for a carrier-grade ONAP
