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 Architecture
• The Stand-Alone and Non-Stand-Alone Architectures
• Detailed presentation of 5G Core key concepts
• An overview of 5G Radio and Cloud technologies

Learn:

• The differences between the 5G Core network and previous core network generations
• How the interworking with previous network standards is defined
• Why certain functionality has been included and what is beyond the scope of 5G Core
• How the specifications relate to state-of-the-art web-scale concepts and virtualization technologies
• Details of the protocol and service descriptions
• Examples of network 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

About the Authors

Stefan Rommer is a Senior Specialist at Ericsson in Gothenburg, Sweden. Since joining Ericsson in 2001 he has worked with different areas of telecommunications, primarily with packet core network standardization and development. He has been involved in 5G standardization from the start and participated actively in 3GPP for several years. Stefan holds an M.Sc. in engineering physics and a Ph.D. in theoretical physics, both from Chalmers University of Technology, Sweden.

Peter Hedman joined Ericsson in 2000 after previously working for the company for five years as a consultant within different areas such as Intelligent Networks and GSM/NMT Gateway development. Since joining Ericsson he has been attending 3GPP SA WG2 contributing to the standardization of e.g. GPRS, EPS, IMS, WiFi-3GPP access interactions, M2M/IoT and 5GS. His current focus is 5G standardization and he is rapporteur for the 5G System procedures specification specified by 3GPP SA WG2. He received his Master's in Computer Science from Lund Institute of Technology.”

Magnus Olsson is an expert in system architecture and standardization at Ericsson. He has worked with the overall mobile network architecture since joining Ericsson in 1995 and has over 10 years of experience in the standardization of mobile systems. He served as the chairman of 3GPP TSG SA WG2 (Architecture Working Group) for four years and has contributed to numerous specifications within this forum. He has been involved in driving the System Architecture Evolution (SAE) work item since its inception within 3GPP. He holds an MSc in Applied Physics and Electrical Engineering from the Linköping Institute of Technology.

Lars Frid is a Director of Strategic Product Management of 5G Core Networks at Ericsson, currently based in Stockholm, Sweden. He has over 25 years of experience of working with wireless data communications in Sweden and in Silicon Valley, California, US. His area of work has covered global standards and technologies for 2G, 3G, and 4G mobile data communications, as well as IP routing, satellite systems, and dedicated mobile data systems for industries and enterprises.His current priorities is to drive product strategies for 5G systems, with a specific focus on business modelling and business development in relation to 5G network architectures and capabilities.Lars holds several patents in mobile communications and is the co-author of two books. He has a Master’s degree in Electrical Engineering from studies at Chalmers University of Technology in Gothenburg, Sweden, and Imperial College of Science, Technology & Medicine in London, UK.

Shabnam Sultana is an expert in standardization architecture at Ericsson. She has worked with the overall mobile network architecture since joining Ericsson in 1993 and has over 15 years of experience in the standardization of mobile systems. She has worked in the areas of North American Systems and associated Standards prior to joining 3GPP. She has been involved in driving the IP Multimedia System (IMS) and System Architecture Evolution (SAE) work since their inception within 3GPP.
