OCNWDAF Release 23.3.0

Oracle Communications Networks Data Analytics Function (OCNWDAF) 23.3.0 is updated with the following enhancements:

  • User data congestion analytics: The OCNWDAF provides User Data Congestion Analytics to consumers (statistical and threshold). It includes information about the congestion experienced during user data transfer over the user plane. The congestion information reported is specific to an Area of Interest (AoI) or a User Equipment (UE). The OCNWDAF provides congestion analytics for a slice based on the Single-Network Slice Selection Assistance Information (S-NSSAI). For more information, see Oracle Communications Networks Data Analytics Function User Guide.

  • Machine Learning (ML) model selection: Machine Learning (ML) Models are programs trained to find patterns within data sets and make predictions on input data. The ML Models are trained over a data set that consists of historical data. The OCNWDAF provides a GUI dashboard to select, train, and optimize one or more ML Models for a given analytics category. For more information, see Oracle Communications Networks Data Analytics Function User Guide.
  • Data collection controller service: The OCNWDAF retrieves data from various sources (for example, NFs such as AMF and SMF) and computes analytics using this data. The Data Collection Controller microservice is introduced in this release. The Data Collection Controller and Data Collection microservices together perform data collection for the OCNWDAF. The Data Collection Controller Service subscribes to all NFs, manages the subscriptions and updates the Analytics Subscription service. The Data Collection Service collects data from the producer NFs and streams it to the CAP4C Analytics Engine for further processing. For more information, see Oracle Communications Networks Data Analytics Function User Guide.
  • Network performance visualization on the OCNWDAF dashboard: The OCNWDAF provides network performance analytics to the consumer. The analytics information primarily includes resource consumption by gNodeB (gNB) and mobility performance indicators in the Area of Interest (AoI).The OCNWDAF GUI is enhanced to display all the available cells in a selected Tracking Area, Session Success Ratio, HO Success Ratio, GNB Computing, Memory, and Disk Usage. User can set a threshold value, select a tracking area, and specify a time interval. The GUI displays all the available cells according to the specified parameters. For more information, see Oracle Communications Networks Data Analytics Function User Guide.
  • OCNWDAF dashboard enhancement: The OCNWDAF GUI has been enhanced with rich visual features for ML Model Selection, NF Load Monitoring, Network Performance, and User Data Congestion Analytics. For more information, see Oracle Communications Networks Data Analytics Function User Guide.
