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 NSA – option 3 call flows

In this section, we will dig into details of the call flow of 5G UE connected to an option 3x-based NSA network. Let us go over the initial registration call flow step by step:

  1. Consider DC-capable UE that moves into the coverage area of a 5G NR radio; the UE sends an Attach Request message to the master eNB, and the Packet Data Network (PDN) connectivity request has a UE Network Capability field with a Dual-Connectivity with New Radio (DCNR) flag on.
  2. Since all signaling is handled by the master eNB, it sends the S1 initial UE message to the Mobility Management Entity (MME), which contains the Attach Request and PDN Connectivity Request with the DCNR bit on.
  3. After a successful authentication procedure, a Diameter Update Location Answer message is sent to the Home Subscriber Server (HSS) by the MME. This message contains the NR as Secondary RAT field, which indicates...
