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.

PDU session establishment in 5G

In Chapter 2, we discussed a Protocol Data Unit (PDU) session, wherein we learned that a PDU provides end-to-end connectivity to user equipment (UE) to avail of data services. A PDU session can be imagined to be a pipe that is associated with every UE and is identified by a PDU session ID; this pipe is used for the user data to flow between the 5G packet core to the UE. The PDU session ID is generated by the UE. Figure 7.1 shows a PDU session along with various Quality of Service (QoS) flows associated with it:

The establishment of a PDU session involves the UE along with a number of network functions. These network functions exchange messages with each other, and when all these message transactions are successful, a PDU session is finally established.

Figure 7.2 describes the procedure through which this end-to-end connectivity is established. It can be noticed here that the participating...
