Requirement Description
The requirement is to
- discover the RAN and Core endpoints at NSMF
- auto-populate the Core and RAN endpoints in the TN Slice Profile Screen (UUI)
- discover the endpoints of CU, DU & RU nodes at NSMF
All these endpoints are required as an input to TN NSSMF to create the logical links that denotes back-haul, front-haul and mid-haul interfaces. Endpoint consists of IPAddress, logicInterfaceID and nexthopinfo.
Note: Core, RAN endpoints are manually entered in UUI and other RAN nodes endpoints are predefined values in the previous releases.
Back-haul endpoints Discovery:
This involves finding the EP (endpoint) details of RAN (CUCP) and Core (AMF) .

Mid-haul endpoints Discovery:
Mid-haul is the connection between the CU and DU network functions.
CUCP & DU EP details:
IP Address: CUCP and DU IP address can be found in the similar way mentioned in the section RAN Node (CUCP) EP details.

Front-haul endpoints Discovery:
Front-haul is the interface between the DU and RU network functions.
DU & RU EP details:
DU - IP Address: DU IP address can be found in the similar way mentioned in the section RAN Node (CUCP) EP details.
