VoNR Control Plane KPIs – Key Performance Indicator

Last updated on 

Voice over New Radio (VoNR) is a technology that enables voice communication over the 5G New Radio (NR) network. The Control Plane Key Performance Indicators (KPIs) for VoNR refer to the metrics that are crucial for assessing and ensuring the performance of the control plane in VoNR communication. The control plane is responsible for managing signaling and control functions in a communication system. Here are some key VoNR control plane KPIs explained in technical detail:

  1. Setup Time:
    • Definition: The time taken to establish a VoNR call, from the initiation of the signaling process to the point where the call is successfully set up.
    • Importance: Lower setup time is desirable as it enhances the user experience and reduces call setup delays.
  2. Call Establishment Success Rate:
    • Definition: The percentage of attempted VoNR calls that are successfully established.
    • Importance: A high success rate indicates a reliable and efficient VoNR setup process.
  3. Latency:
    • Definition: The time delay between the initiation of a signaling event and the corresponding response or action in the control plane.
    • Importance: Low latency is crucial for real-time communication to ensure minimal delays and a seamless user experience.
  4. Handover Success Rate:
    • Definition: The percentage of VoNR calls that successfully complete handovers between different cells or network nodes.
    • Importance: Handover success is critical for maintaining call continuity during user mobility.
  5. Session Management Efficiency:
    • Definition: Measures the efficiency of managing VoNR sessions, including call setup, modification, and release procedures.
    • Importance: Efficient session management contributes to optimal network resource utilization and a smooth user experience.
  6. Signaling Overhead:
    • Definition: The amount of signaling messages exchanged between the user equipment (UE) and the network during VoNR communication.
    • Importance: Excessive signaling can strain network resources and impact performance. Monitoring signaling overhead helps optimize network efficiency.
  7. Control Plane Resource Utilization:
    • Definition: The extent to which control plane resources, such as processors and memory, are utilized during VoNR operations.
    • Importance: Efficient resource utilization ensures that the control plane can handle the signaling load effectively without degradation in performance.
  8. Call Drop Rate:
    • Definition: The percentage of VoNR calls that are prematurely terminated or dropped.
    • Importance: A low call drop rate is essential for providing a reliable and uninterrupted voice communication service.
  9. Interoperability:
    • Definition: The ability of VoNR to seamlessly

interoperate with other network elements, devices, and protocols.

  • Importance: Ensuring interoperability is crucial for a smooth user experience and the seamless integration of VoNR with existing and future network technologies.
  1. Security and Authentication Performance:
    • Definition: Measures the effectiveness of security mechanisms and authentication processes in the VoNR control plane.
    • Importance: Robust security is essential to protect VoNR communications from unauthorized access and ensure the privacy of users.
  2. Error Handling and Resilience:
    • Definition: Evaluates the system's ability to detect and recover from errors or failures in the control plane.
    • Importance: A robust error handling mechanism is crucial for maintaining service continuity and minimizing the impact of faults.
  3. Resource Reservation Efficiency:
    • Definition: Examines how efficiently resources are reserved in the control plane for VoNR sessions.
    • Importance: Efficient resource reservation contributes to optimal network performance and resource utilization.

Monitoring and optimizing these VoNR control plane KPIs are essential for network operators and service providers to deliver a high-quality voice communication service over 5G networks. Regular assessment and improvement of these KPIs help ensure a reliable and efficient VoNR deployment, providing users with a seamless and satisfactory communication experience.
