E2E Model structure optimization
- New/Enhanced features
- Introduce Slice Profile Templates to carry user slicing subnet requirements, in ONAP we have 3 kinds of Slice Profile Templates, for RAN, Core and CN separately.
- Add RAN NSST and TN NSST to support RAN and TN NSSI deployment, in TN side, also add TN Network Requirement Template to support TN connection links creation.
- Has allotted resource relationship between slice subnet requirements and subnet slice resource, see 1, 2, 3. Allotted resource 4 is inner TN, between subnet resource and logical network resource.
- Update relationship between NST and NSST using allotted resource, instead of nested, see 5.
- Supprting for both option 1 and option 2
ONAP option 1 and 2 differs on the RAN and FH/BH relationship, in option 1, RAN NSSMF will decide FH/MH requirements and send to TN side, so RAN NSST will nest FH/MH NSST, and slice profile requirements will contain not only RAN side requirements but also FH/MH. In option 2, FH and MH are independent requirments when doing E2E requirements decomposition. Detailed background of option 1 and 2, please see E2E Network Slicing Use Case in R7 Guilin.

In ONAP, we refer 3GPP proposal 3GPP S5-203419 and S5-203420.rar in TS 28.541, and introduce Endpoint(EP) to ONAP Network Slicing model.
3GPP reference:
ONAP Model:
Design Time: In R7, EP allocation starts from UUI, when doing service profile decomposition to slice profiles, NSMF will give EP information along with slice subnet requirements delivery to RAN and Core, TN will get the information and store EP Ids after RAN and Core instantiation.
