책소개

5G Core Networks: Powering Digitalization provides an overview of the 5G Core network architecture, as well as giving descriptions of cloud technologies and the key concepts in the 3GPP rel-15/16 specifications. Written by the authors who are heavily involved in development of the 5G standards and who wrote the successful book on EPC and 4G Packet Networks, this book provides an authoritative reference on the technologies and standards of the 3GPP 5G Core network. Content includes: An overview of the 5G Core ArchitectureThe Stand-Alone and Non-Stand-Alone ArchitecturesDetailed presentation of 5G Core key conceptsAn overview of 5G Radio and Cloud technologies Learn The differences between the 5G Core network and previous core network generationsHow the interworking with previous network standards is definedWhy certain functionality has been included and what is beyond the scope of 5G CoreHow the specifications relate to state-of-the-art web-scale concepts and virtualization technologiesDetails of the protocol and service descriptionsExamples of network deployment optionsProvides a clear, concise and comprehensive view of 5GS/5GCWritten 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 architectureExplains the Service Based Architecture, Network Slicing and support of Edge Computing, describing the benefits they will bringExplains what options and parts of the standards will initially be deployed in real networks, along with their migration paths
