Since the NS can be composed VNFs, CNFs, PNFs and nested NSs, the ETSI NS model is well suited to describe the hierarchical structure of 3GPP Network Slice Subnets.

Design Time:

...

1. Onboard 5G Core NFs (NRF, PCF, UDM, AUSF, NEF, AMF, SMF, UPF, ...) into SDC
2. Onboard RAN NFs (vCU, vDU) into SDC
3. In SDC, design a "Central" Network Service composed of
   1. "Central" NFs (NRF, PCF, UDM, AUSF, NEF)
   2. Virtual Link (Control Network) for the SBA interface
   3. SAP(s) for all of the exposed entry points
4. SDC distribute the resulting SOL007 NS package to the ETSI Catalog (and any one else interested, SO??)
5. In SDC, design a "User Plane" Network Service composed of:
   1. "user plane" NFs (AMF, SMF, UPF)
   2. Virtual Link (Control Network) for the SBA interface
   3. Virtual Link (RAN Network) for the interface to the RAN components
   4. Virtual Link (Data Network) for the (external) data/internet interface
   5. SAP(s) for all of the exposed entry points
6. SDC distribute the resulting SOL007 NS package to the ETSI Catalog (and any one else interested, SO??)
7. In SDC, design a "RAN" Network Service composed of:
   1. "RAN" NFs (CU, DU)
   2. Virtual Link (Control Network) for the OAM interface
   3. Virtual Link (RAN Network) for the interface to the RAN components
   4. Virtual Link (Front-Haul) for the radio interface
   5. SAP(s) for all of the exposed entry points
8. SDC distribute the resulting SOL007 NS package to the ETSI Catalog (and any one else interested, SO??)
9. In SDC, design a "Complete" Network Service composed of:
   1. Scalable reference to the Central NS
   2. Scalable reference to the UP NS
   3. Scalable reference to the RAN NS
   4. Virtual Link (Control Network) for the OAM interface
   5. Virtual Link (Data Network) for the (external) data/internet interface
   6. Virtual Link (RAN Network) for the interface to the RAN components
   7. SAP(s) for all of the exposed entry points
10. SDC distribute the resulting SOL007 NS package to the ETSI Catalog (and any one else interested)
11. In SDC, Design a "Central" Service composed of
    1. A reference to the "Central" Network Service
    2. A CDS blueprint (CBA) for configuring the "Central" Service
    3. Behavioral policies for the "Central" Service
12. SDC distribute the resulting "Central" Service package
13. In SDC, Design a "User Plane" Service composed of
    1. A reference to the "UP" Network Service
    2. A CDS blueprint (CBA) for configuring the "UP" Service
    3. Behavioral policies for the "UP" Service
14. SDC distribute the resulting "UP" Service package
15. In SDC, Design a "RAN" Service composed of
    1. A reference to the "RAN" Network Service
    2. A CDS blueprint (CBA) for configuring the "RAN" Service
    3. Behavioral policies for the "RAN" Service
16. SDC distribute the resulting "RAN" Service package
17. In SDC, Design a "Complete" Service composed of
    1. A reference to the "Complete" Network Service
    2. A CDS blueprint (CBA) for configuring the "Complete" Service
    3. Behavioral policies for the "Complete" Service
18. SDC distribute the resulting "Complete" Service package

Runtime
