"5G RAN Slice PRB Prediction rApp" Presentation & demo from from Sunil N
- Great demo last week. Thank you 👍😊
- Having some problem pushing PRs to Gerrit. Working on it.
- Suggest a wiki page for any additional useful information.
- Perhaps here (in Integration space): Discussion
- Last week:
- Slides:
Focus on optimised allocation of PRBs to different slices
Based on NSSI performance reports from RAN NSSMF (15min)
- Uses 1 week windows (80% for training, 20% for model testing
- Tried several model types. Settled on LSTM.
- Used to predict DL PRB usage per NSSI (15 min)
Current PRB prediction rApp policy - modify PRB allocations if ( predicted usage < current ) or ( predicted usage > current * 120% )
- When triggered queries past 1 week data from InfluxDB & predicts
- Updates sent direct to NSSMF API
- Currently performance data is written direct into InfluxDB, then publishes triggered by NSSMF notification
Uses simulated NSSMF (3gpp 28.532 interfaces & notifications) as rApp
- Plan to move prediction service from inside rApp uService to AIMLFW platform
- Plan to extend to Uplink too.
- Next step:
- Create new wiki page for use case (landing page) in Integration wiki space
- Upload code, data, etc - initially in NONRTRIC rAppManager repo, but can re-file later
- Slides:
AIMLFW Github Actions (subhash):
- Trying to create a heavy-weight runner for test/integration
- Working with LF.
- See also slack
- https://jira.linuxfoundation.org/plugins/servlet/desk/portal/2/IT-28781
- Any help how to do this?
- maybe bimo fransiscus asisi is doing something similar?
- Also might be able to re use facilities in WINLAB/COSMOS? Again Bimo & Martin & Ivan is looking into this.
