Preface
This book aims to describe the deployment of 5G-NSA and 5G-SA.
For the 5G-NSA mode, dual MR-DC connectivity is based on radio measurements allowing the master 4G base station MeNB to add or to remove a 5G secondary node SgNB.
For the 5G-SA mode, the mobile is attached to the 5G core network. Even though this book is devoted to the radio access network, the mobile registration, establishment procedures and re-establishment procedures are also explained.
This book describes the architecture of the NG radio access network and the 5G-NR radio interface according to 3GPP (3rd Generation Partnership Project) specifications.
The 5G-NR radio interface was introduced in Release 15 of the 3GPP standards.
The 5G-NR radio interface is the interface between the UE mobile (User Equipment) and the 5GC mobile network (5G Core).
Chapter 1 presents the 5G-NSA and the 5G-SA deployment architecture. It describes the radio access entities and functions of the 5G-SA core network and presents the functions supported by the radio access and the 5GC core network.
In order to prepare RAN virtualization, the radio protocols of the gNB entity are supported by two units: a centralized unit and a distributed unit. This separation creates new interfaces called F1 on the radio access.
Chapter 2 presents the interfaces between the entities of NG-RAN radio access. It describes the protocol architecture on the Xn interface, the NG interface and the F1 interface, as well as the procedures for managing ...
