Jira Ref. CPS-277 - Getting issue details... STATUS
Analyze all API GET calls listed on this page: https://wiki.onap.org/display/DW/CPS+APIs
(#2 and #21 have already been analyzed and required queries been identified)
- Ensure use case is clear using given model and data example
- Find out required (new) query functionality in CPS (several API calls might need the same CPS functionality)to 'find' the required data given the provided parameters (request payload) and model.
- One (Slicing) 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 NW Slicing specific data.
A/C
- Wiki Page with the conclusion for each API call
- Add new query functionality if needed to https://wiki.onap.org/display/DW/CPS-235%3A+Overview+of+%28early%29+CPS+Query+and+Update+Scenarios
- Review with the full team
To be noted: Dataspace name is fixed to NFP-Operational.

| Question | Comment | |
|---|---|---|
| 1 | API 9 & 10: There are multiple placeholders for it in the same ancestor of DU, RTRIC, CUUP and CUCP NFs. For DU-list we have identified: cps-ran-schema/GNBDUFunction/attributes/RRMPolicyRatio/attributes/sNSSAI For the DU list, we can also use the sNSSAI from cell-list which comes under DU. For cell-list we have identified: cps-ran-schema/NRCellDU/attributes/pLMNInfoList/sNSSAIList/sNSSAI Would you please guide us as to what would be the right attributes to be considered in the search for these GET APIs? | From: ahila.pandaram@wipro.com <ahila.pandaram@wipro.com> As per the current SDN-R implementation, sNSSAI is configured in NRCellDU, NRCellCU & gNBCUUP. NearRTRIC is configured only in closed loop scenarios. So please make use of this for the APIs (9) & (10). cps-ran-schema/GNBDUFunction/NRCellDU/attributes/pLMNInfoList/sNSSAIList/sNssai |
| 2 | API 12: We did not identify the slice config attribute for API#12 to be mapped in the Network Slicing. Kindly provide us with the right model and data. | From: ahila.pandaram@wipro.com <ahila.pandaram@wipro.com> API (12) can make use of this: cps-ran-schema/NearRTRIC/attributes/pLMNInfoList/sNSSAIList/sNssai |
