5 OCNWDAF Analytics

This chapter describes the OCNWDAF analytics information.

5.1 OC-NWDAF Analytics

An OCNWDAF consumer can avail analytics information for different analytic events. Alternatively, the consumers can subscribe or unsubscribe to specific analytics information as a one-time event or periodically get notified when a specifically defined event is detected. The analytics information provided by the OCNWDAF is either statistical information on past (or current) events or predictive information which can be used to balance the resources on the network.

The OCNWDAF assists in collecting and analysing data in a 5G network. In a 5G network, the consumers and producers of data are 5GNFs, AFs and OAM. The OCNWDAF function allows the Communications Service providers (CSPs) to efficiently monitor, manage, automate, and optimise their network operations by analysing the data collected across the network.

Listed below are the type of analytics reports that OCNWDAF can provide:

• Report of historic statistical analytics
• Report when a threshold of a statistical analytic is crossed
• Predictions
• Report UE abnormal behaviour

The OCNWDAF provides the following analytics information:

• Slice Load level information
• UE mobility information
• UE Abnormal behaviour information (unexpected UE location)
