5G Core Networks: Powering Digitalization

5G Networks: Powering Digitization provides an overview of the standard 5G Core, as well as giving descriptions of cloud technologies- considered central for 5G- and the key concepts in the 3GPP rel-15/16 specifications.Written by the authors who are heavily involved in the development of the standards and who wrote the successful EPC and 4G Packet Networks, 2nd edition, this book provides an authoritative reference on the technologies and standards of 3GPP's 5G at the network layer.Content includes:- 5G Radio technologies: NR (New Radio) and the evolution of LTE, Massive MIMO, multi-user beamforming and virtual RAN; cloud technologies; web software concepts- Option 3/NSA- An overview of the 5G Core Architecture - Detailed presentation of 5G Core key conceptsLearn: - The differences between 5G system / core network and previous incarnations of the core network- How the interworking with previous standards is expected to happen- Why certain functionality has been included and what is beyond the scope of 5GC- How the specifications relate to state of the art web-scale concepts and virtualization technologies- Which part of the specifications to find the the descriptions of certain functionality- Information about how the different parts of the specifications fit together- Protocol and service descriptions from an architectural and overall system perspective- The main stream deployment options- Provides a clear, concise and comprehensive view of 5GS/5GC- Written by established experts in the 5GS/5GC standardization process, all of whom have extensive experience and understanding of its goals, history and vision - Covers potential service and operator scenarios for each architecture- Explains the Service Based Architecture, Network Slicing and support of Edge Computing, describing the benefits they will bring- Explains what options and parts of the standards will initially be deployed in real networks, along with their migration paths.
