In this chapter, we have presented the introductory architectures, the various domains or areas, and the network elements of mobile communications networks based on the GSM, UMTS, and LTE systems. The 5G system is also covered in appropriate sections of this chapter. We then presented the global 3GPP standardizations process of various technical specifications based on which mobile communications systems and networks are designed and built. The evolutions of mobile communications systems and networks in terms of 3GPP system architectures release are also discussed.

The reader is advised to get familiar with the various aspects of a 3GPP TS. To start with, select a particular mobile communications system and then use the 3GPP specification series [2] as the guiding resources to download and study the technical specifications of a particular series and the subject area of interest. Get an overview of the various protocol layers, interfaces, procedures, and functions performed by a particular network element.

This chapter was the introductory one, for the reader, whose contents are general in nature and thus applicable to the 5G system also. The various protocols, procedures, and functions performed by a mobile communications network and its elements/entities shall be described in detail in the subsequent chapters of this book. Design, development, and implementation aspects of a network element in the software code shall be also presented in the subsequent chapter.
