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.

Voice over New Radio (VoNR)

The combination of Voice over Long-Term Evolution (VoLTE) and Voice over NR (VoNR) will be the long-term voice infrastructure for mobile service providers. In this chapter, we will discuss the main concepts behind future VoNR networks. Furthermore, VoNR will be analyzed from end to end with a focus on the architecture requirements, initial procedures, call establishment, and interworking.

VoNR has got some very close similarities to VoLTE. For example, both technologies require an IP Multimedia Subsystem (IMS) for call signaling, and both technologies employ their Radio Access Network (RAN), transport, and core networks to carry voice media in the form of IP packets.

We’ll go through the following topics in this chapter:

  • VoNR concepts and drivers
  • VoNR high-level architecture
  • VoNR initial procedures
  • VoNR call procedures
  • Interworking and voice call continuity
