I Introduction
This part contains eight chapters containing the background and introductory aspects and areas of mobile communications systems and networks based on GSM, GPRS, UMTS, LTE, and 5G systems. The materials presented in this part are general in nature but applicable across the mobile communications systems and networks. Even if a reader is starting a career in the LTE or 5G system and network, as a developer or O&M person, one has to know the major key concepts from the legacy GSM/UMTS networks as well.
Part II Operation and Maintenance
This part contains three chapters covering various aspects and areas of the troubleshooting and resolution of mobile communications systems and network issues.
Part III Development of Mobile Communications Systems
This part contains four chapters covering various aspects and areas of the development of mobile communications systems protocol stack and layers based on the 3GPP standards and their technical specifications. This part also describes hardware platforms to be used for the development of mobile communications systems network elements.
Part IV 5G System and Network
This part contains seven chapters covering various aspects and areas of a 5G system and network based on its first Release 15 as standardized by the 3GPP. Also, an overview of the enhancements made into the existing features of the 3GPP Release 15 and the addition of new services or capabilities which have been added as part of the 3GPP Release 16 and Release 17 are covered in this part.

Acknowledgments
I thank my dear friends and colleagues for offering encouragement and valuable comments during the preparation of this book. During my time in Hughes Software Systems (now known as Aricent, located in Gurgaon, India), I had the opportunity to work with very smart and talented people who were generous in sharing their knowledge and experience. Special thanks also go to Mr. Sumit Kasera (AVP, Technology at Aricent, Gurgaon, India) for his valuable feedback on this book.
I would also like to thank 3GPP for permitting me to reproduce a few snapshots from the concerned 3GPP technical specifications.
I would also like to thank and appreciate John Wiley & Sons Ltd., UK, and its acquisition, editorial, production, and publishing staff, for their continuous support and cooperation during the entire process of this book’s production.
