Overview of this book

We are living in an era where ultra-fast internet speed is not a want, but a necessity. As applications continue to evolve, they demand a reliable network with low latency and high speed. With the widespread commercial adoption of driverless cars, robotic factory floors, and AR/VR-based immersive sporting events, speed and reliability are becoming more crucial than ever before. Fortunately, the power of 5G technology enables all this and much more. This book helps you understand the fundamental building blocks that enable 5G technology. You’ll explore the unique aspects that make 5G capable of meeting high-quality demands, including technologies that back 5G, enhancements in the air interface, and packet core, which come together to create a network with unparalleled performance. As you advance, you’ll discover how to design and implement both 5G macro and private networks, while also learning about the various design and deployment options available and which option is best suited for specific use cases. After that, you’ll check out the operational and maintenance aspects of such networks and how 5G works together with fixed wireline and satellite technologies. By the end of this book, you’ll understand the theoretical and practical aspects of 5G, enabling you to use it as a handbook to establish a 5G network.

VoNR initial procedures

Before the device can conduct VoNR calls, it must pass through a series of initial procedures. These procedures are as follows:

  • Subscriber provisioning
  • IMS connectivity establishment
  • IMS registration
  • Third-party registration

Subscriber provisioning

Several network elements must be provisioned appropriately with subscriber information for VoNR services. Some of these elements are the UDM, the Home Subscriber Server (HSS), the TAS and Service Centralization and Continuity (SCC) application servers, the Policy Control Function (PCF), and AAA servers in case of Wi-Fi calling.

The information indicating whether a subscriber is permitted access to the IMS for voice services is contained within the subscriber profile in the UDM, which acts as a central repository of subscriber information. The subscriber profile contains appropriate QoS profiles for the subscriber, and it also contains whether roaming is supported. Likewise, the UDM...
