What are the key performance indicators and metrics for RAN in cloud native 5G networks?

1 RAN basics

RAN is the part of the network that handles the radio signals between the devices and the base stations. It consists of two main components: the distributed units (DUs) and the centralized units (CUs). The DUs are responsible for processing the radio signals, while the CUs handle the control and coordination functions. In cloud native 5G networks, the RAN functions can be virtualized and deployed on cloud platforms, allowing for more flexibility, efficiency, and scalability.

3 RAN metrics

RAN metrics are the data points that are used to calculate the KPIs. They include parameters such as signal strength, signal quality, interference, modulation, coding, resource utilization, and traffic load. These metrics can be collected from various sources, such as the devices, the base stations, the cloud platforms, or the network management systems. By collecting and correlating these metrics, network operators can gain insights into the network behavior and performance.

4 RAN optimization

RAN optimization is the process of adjusting the network configuration and parameters to improve the KPIs and meet the service level agreements (SLAs). It involves techniques such as load balancing, interference management, beamforming, carrier aggregation, and network slicing. These techniques can be applied dynamically and automatically, using artificial intelligence (AI) and machine learning (ML) algorithms, to adapt to the changing network conditions and user demands.

5 RAN challenges

RAN faces several challenges in cloud native 5G networks, such as the complexity of managing multiple layers and domains, the heterogeneity of devices and services, the security and privacy of data and communications, and the interoperability and compatibility of standards and protocols. These challenges require innovative solutions and best practices, such as the use of open interfaces, common APIs, modular architectures, and edge computing.

6 RAN benefits

RAN offers many benefits for cloud native 5G networks, such as the reduction of capital and operational expenses, the improvement of network performance and user experience, the enhancement of network security and resilience, and the enablement of new services and applications. By leveraging the power of cloud computing, virtualization, and automation, RAN can provide a more agile, efficient, and scalable network for the 5G era.
