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.

REST in 5G

In this section, we will learn about the applicability of REST in 5G, and how all the various concepts that we have gone through in the previous sections come together in a 5G system.

Figure 3.10 represents some of the RESTful interfaces in a 5G system:

We explore the details of each of them and understand the services provided to and consumed by each of these NFs. We will also understand the role of each of these services and how they contribute to the functionality of the network function as a whole.

AMF services

The following is a list of services offered by the AMF per 3GPP Release 16, 29.518; note that each service has a name associated with it and can have one or more service operations. These communications will be with a known consumer in the form of a request and response:

  • The Namf_Communication service enables the network function to communicate via the non-access Statum...
