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.

5G network concepts

In this section, we will go over the various new concepts and terminologies introduced with 5G.

PDU sessions

A PDU session is the logical connection between the UE and the data network. It is by the means of this logical connection that the UE is able to browse data, place calls, and so on.

Figure 2.16 – QoS in 5G

This connection determines the QoS experienced by the user. Consider a case in which the UE initiates an attach request to the network so that it can access the internet; what happens in the background is that a logical connection (or pipe) is created between the UE and the 5G network that carries the data flows associated with browsing the internet.

This logical connection is defined by attributes such as a QoS parameter. Certain PDU sessions require a guaranteed QoS, which must be provided by the network if the PDU session is accepted. Hence, the network must reserve resources for this kind of PDU session...
