Near-Real-time RIC X-APPs (RICAPP)

Primary Goals: Expand the community working on open source xApps for O-RAN SC. 

Enhance the set of open source xApps in support of the RSAC use cases (traffic steering, network slicing) as well new use cases.

Update and enhance existing xApps 

G release plan (<date>):

  • New HW-Rust xApp to support RUST framework not ready for G-release --Johannes Becker 
  • HW(python) - RIC Subscription using python xApp framework 
  • RC xApp - GRPC interface support on RC xApp

RICAPP-201 -KPIMON xApp (G Release)

RICAPP-200 - RC xApp (G-Release)

RICAPP-202 - upgrading protofile and modified NodebHandler to build CELL-RAN map (cell_map)

G release highlights/accomplishments (16-Dec-2022):

AD xApp :-

  • Removal of pushing data into influxdb when xApp starts.
  1. Either UE's KPIs should be continuously stored into influxDB from KPIMON OR
  2. We will need to run script manually to populate influxDB from .csv separately 
  • changes in AD xApp to read live data from influxDB for inference
  • Addition of Python script to read static data and keep pushing into RICPLT lnfluxDB
  • Addition of exception module to handle errors and exceptions
  • Addition of configuration module to update
    • InfluxDB configuration (near RT RIC instance or external)
    • KPIs 
  • parameter tuning and functionality addition for improvements

KPIMON-GO xApp :-

  • E2SM KPM version upgraded to 2.0
  • Added a feature to build a RAN cell map. 

RC xApp:
