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.

Service-based architecture

As 5G has been developed on cloud principles, 5G NFs also follow web-scale application principles, so it is designed in a manner in which the NFs provide and consume services to and from each other. Hence, 5G is based on a producer-consumer model. The 3rd Generation Partnership Project (3GPP) has chosen to use the widely adopted Representational State Transfer (REST) model to support communication between various NFs in 5G.

A Service-Based Architecture (SBA) is a system architecture in which the functionality of the system is achieved by applications providing services and consuming services to and from each other. In the context of a 5G core, a service-based interface is between two NFs that provide or consume a service to or from each other.

Figure 3.3 portrays the producer–consumer model of communication. In this example, consider three applications – Application A hosting service A, Application B hosting service B, and Application...
