Summary
In this chapter, we have seen the various procedures in 5G and how they come together to service a subscriber. We have gone over how a PDU session is established in 5G, and we have gone over how to connect a 4G radio to work with a 5G interworking function. We have seen how to establish a voice call over New Radio and finally, we have seen how Wi-Fi access integrates with a 5G system. By the end of this chapter, we now understand the 5G call flows in detail and have developed a near-practical understanding of the messages exchanged between the various network functions to bring about a data or a voice call in 5G.
In the upcoming chapters, we will delve further into 5G-NSA and 5G-SA system architectures that leverage these procedures. The next chapter introduces exclusive VoNR concepts.
