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 high-level architecture

There are three main components associated with the VoNR architecture. These are the 5G New Radio (NR) access network, 5G core network (5GC), and IP multimedia subsystem.

5G NR access and core networks

5G NR access and core networks transport call signaling and voice packets.

Call signaling is performed as a Session Initiation Protocol (SIP). SIP is the control signaling used between the device and the IMS to initiate, maintain, and terminate real-time applications such as voice, video, and messaging. From a Quality of Service (QoS) perspective, it is critical that signaling cannot be delayed or dropped. In VoNR, SIP is transported through the 5G system, and the 5G system is responsible for meeting the necessary QoS requirements.

Once the call is initiated, associated voice packets are carried by the 5G system in the form of a Real-time Transport Protocol (RTP). It is possible to drop some voice packets without degrading the call quality. However...
