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.

Wi-Fi attach

One of the prime features of the 5G core network is its capability to inter-work with different types of access networks, both 3GPP-based and non-3GPP-based. One such network is Wi-Fi. The 5G radio can coexist with Wi-Fi access to cover coverage gaps. Hence, denser access can be planned with complementing radio access technologies. This is how Wi-Fi and New Radio (5G radio) can complement each other and do not need to be treated as competing technologies.

We will now go over the Wi-Fi attach procedure:

Step 1: The UE sends the IKE_SA_AUTH exchange message to ePDG (IWF-interworking function) to create the IPSec tunnel.

Step 2: The UE sends the IKE_SA_AUTH exchange message to the SMF+PGW-C as a GTP Create Session request by including the P-CSCF IPv4 or IPv6 request and DNS IPv4 or IPv6 container identifier in APCO IE options. The ePDG checks the UE capability information to determine whether...
