Analyse API PUT calls listed on this page for E2E slicing use case (priority 1 and 2)
- Ensure use case is clear using model and data example
- Find out required (new) update functionality in CPS (several API
...
- calls might need the same CPS functionality.
- One API call might require more
...
- than one CPS-Core call, indicate in the report if this is the case
- One API call might need to access more
...
- than one model (report!)
- Distinguish between NCMP (ran network data) and CPS-Core access for slicing specific data.
A/C
- Wiki Page with a conclusion for each API call (see toines example for API call no.2 https://wiki.onap.org/display/DW/CPS+APIs)
- Add new update functionality if needed to https://wiki.onap.org/display/DW/CPS-235%3A+Overview+of+%28early%29+CPS+Update+Scenarios

1 | What to do if the value already exists when inserting it into a list? | reject it or replace it without warning? | It can be rejected. |
2 | Would this be a new entry or is this updating an existing entry in a list for no. 4, 5, and 6? | Create a new entry, if it does not exists. Update, if it already exists. | |
3 | Confirm the exact list you a referring to in no 7? | He is referring to the list below. The expected behavior here is that update to the parent and the child list. It needs to be updated for NRCellDU, NRCellCU & GNBCUUPFunction +--rw rRMPolicyMemberList* [idx] | | +--rw idx uint32 | | +--rw mcc Mcc | | +--rw mnc Mnc | | +--rw sNSSAI? SNssai |
