5G End to End KPI – Accessibility, Integrity and Utilization

Last updated on 


5G End-to-End Key Performance Indicators (KPIs) are metrics used to assess the overall performance of a 5G network from end to end. These KPIs provide insights into the accessibility, integrity, and utilization of the network, which are critical factors in evaluating its effectiveness. Let's break down each of these aspects technically:

  1. Accessibility KPIs:
    • Description: Accessibility KPIs measure the ability of users to access and connect to the 5G network, indicating the network's coverage and availability.
    • Technical Details:
      • RAN Accessibility: This KPI assesses the accessibility of the Radio Access Network (RAN) and is often measured by the success rate of connection requests.
      • Cell Reselection Success Rate: Indicates how successfully a device reselects or hands over to different cells within the network.
      • Initial Connection Success Rate: Measures the success rate of initial connection attempts by user devices.
  2. Integrity KPIs:
    • Description: Integrity KPIs focus on the reliability and accuracy of data transmission, ensuring that information is delivered without errors or corruption.
    • Technical Details:
      • Packet Error Rate (PER): Evaluates the percentage of transmitted packets that contain errors. A lower PER indicates higher data integrity.
      • BLER (Block Error Rate): Similar to PER, BLER assesses the error rate at the block level in data transmission.
      • Handover Success Rate: Measures the success rate of handovers between different cells or network nodes without compromising data integrity.
  3. Utilization KPIs:
    • Description: Utilization KPIs focus on the efficient use of network resources to ensure optimal performance and capacity utilization.
    • Technical Details:
      • Resource Utilization: Evaluates how efficiently network resources, including spectrum and processing capacity, are being utilized.
      • Throughput: Measures the actual data transfer rate on the network, indicating its capacity to handle data traffic.
      • Congestion Rate: Assesses the occurrence of network congestion, indicating areas where additional capacity may be needed.
  4. End-to-End Measurement:
    • Technical Details:
      • End-to-End KPIs consider the entire network architecture, including the Radio Access Network (RAN), Core Network, and backhaul links.
      • These KPIs are measured from the user device's perspective, providing a holistic view of the user experience.
  5. Quality of Service (QoS) Metrics:
    • Technical Details:
      • Accessibility and integrity are often evaluated in the context of QoS metrics, which include parameters like latency, jitter, and packet loss.
      • QoS metrics contribute to the overall user experience, especially in applications with strict performance requirements, such as real-time communication or gaming.
  6. Control Plane and User Plane KPIs:
    • Technical Details:
      • Control plane KPIs assess the signaling and control mechanisms in the network, ensuring efficient establishment and management of connections.
      • User plane KPIs focus on the actual data transfer and user communication, emphasizing throughput, latency, and data integrity.
  7. Dynamic Network Optimization:
    • Technical Details:
      • 5G networks employ dynamic optimization techniques based on real-time data and analytics.
      • Self-optimizing networks (SON) and artificial intelligence (AI) algorithms contribute to adjusting network parameters for improved accessibility, integrity, and utilization.
  8. Benchmarking Against Standards:
    • Technical Details:
      • End-to-End KPIs are often benchmarked against established standards and specifications, such as those defined by the 3rd Generation Partnership Project (3GPP).
      • Compliance with standards ensures interoperability and consistency in performance measurement.

In summary, 5G End-to-End KPIs for accessibility, integrity, and utilization provide a comprehensive view of the network's performance. Technical metrics related to successful connections, data reliability, and efficient resource usage contribute to assessing the overall effectiveness of the 5G network in delivering a reliable and high-performance user experience.
