5G RAN Service Modeling & Definition in R5 Frankfurt

BUSINESS DRIVERS

This section describes Business Drivers for this Use Case.

Executive Summary - This use case is will define a creating a 5G Service to represent a 5G gNB which will be important to attach 5G resources (PNFs/DU, VNFs/CU) such that the infrastructure to deliver a 5G service has been properly instantiated for the Day0/Day1 deployment.  

Business Impact - This use case, defining a 5G service (representing a 5G gNB) is vital to underpin defining and modeling a Network Slice. This use case will identify some of the key gaps in defining a 5G service both in design time and run time. The 5G orchestration process needs to be defined. Examples of "what is a 5G Service" (i.e. does it include a RAN, Core, Transport?). Identifying Gaps in SDC and Controllers to orchestrate a 5G service. Bringing the open-source ONAP community and various involved platform components to come together to come to some common understanding and agreements as to what a 5G service should be, and how a 5G service would be orchestrated. ANR, Nested services.

Business Markets - Applies to Wireless domain market. In so much the transport is involved with getting a 5G service orchestrated, transport and optical domains are also important.

Funding/Financial Impacts - TBD.

Organization Mgmt, Sales Strategies - There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider..

Modeling Standards Bodies

The Platform Data & Information model needs to harmonize with models from the following standards bodies or modeling groups.

ETSI SOL001 ... 007 

PNFD modeling (Model S/C)

5G Model (3GPP, SA5, 5GNRM)

ORAN (WGs) - NetConf/Yang WG4

Open ROADM (reconfig optical add/drop multiplexer)

ONF (equipment specific conditional package for wireless transport/air interface)

ISOMII

OTCC (Optical transport config & control)
