1. Definition and Role:

The NWDAF is defined within the 3GPP specifications, specifically in the context of 5G networks. Its primary role is to collect and analyze network data to provide insights, recommendations, and support various functionalities within the 5G network.

2. Key Functionalities:

a. Data Collection:

NWDAF collects data from various points within the 5G network. This data could include user plane data, control plane data, Quality of Service (QoS) metrics, and other relevant network parameters.

b. Data Analytics:

Once data is collected, the NWDAF performs advanced analytics on this data. This involves processing the collected data to derive meaningful insights. For instance, analyzing user behavior, predicting network congestion, or identifying potential network anomalies.

c. Policy and Charging Control (PCC):

NWDAF provides critical inputs to the Policy and Charging Control function in the 5G network. By analyzing network data, NWDAF can provide recommendations or decisions related to policy enforcement, QoS adjustments, and charging mechanisms.

3. Integration with Other Network Functions:

NWDAF doesn't operate in isolation. It integrates with several other network functions and entities within the 5G architecture, such as:

  • AMF (Access and Mobility Management Function): For mobility-related analytics and insights.
  • SMF (Session Management Function): For session-specific analytics and recommendations.
  • PCF (Policy Control Function): To provide data-driven inputs for policy decisions.
  • CHF (Charging Function): For charging-related analytics and recommendations.

4. Benefits:

The inclusion of NWDAF in the 5G architecture brings several benefits:

  • Enhanced Network Efficiency: By analyzing network data, NWDAF helps in optimizing network resources, improving user experience, and ensuring efficient network operations.
  • Predictive Analytics: NWDAF's capabilities allow for predictive analytics, enabling proactive measures to address potential network issues or congestion.
  • Dynamic Policy Control: With insights from NWDAF, the network can dynamically adjust policies, QoS parameters, and charging mechanisms based on real-time or historical data.

Conclusion:

In summary, Nokia's NWDAF is a pivotal component within the 5G network architecture, responsible for collecting, analyzing, and providing insights based on network data. Its integration with various network functions ensures efficient operations, optimal resource utilization, and enhanced user experience in 5G networks.
