Mobility Management in LTE Heterogeneous Networks

This book is the first of its kind, compiling information on the Long-Term Evolution (LTE) standards, which are enhanced to address new mobility-related challenges in Heterogeneous Networks (HetNets). It identifies the related challenges and discusses solutions and the simulation methodology for modeling HetNet mobility – cutting-edge information that was previously accessible only in the form of 3GPP specifications and documents, and research papers. The book reviews the current LTE mobility framework and discusses some of the changes for enhancing mobility management in HetNets. It describes the measurement procedures, handover (HO) mechanisms and HO success/failure scenarios.

HetNets are intended to provide very high spectral e?ciency while ensuring seamless coverage by deploying low-power nodes within the umbrella macrocell network. While mobility management in homogeneous networks is well understood, LTE standards are being enhanced to address the HetNet-specific mobility management challenges emerging.

The book addresses these aspects in a succinct and understandable form, offering a valuable resource for researchers and professionals working in the area of HetNet mobility and a ready reference guide for practicing engineers and researchers.

 is Principal Wireless Architect at Mojo Networks, where he works on Radio Resource Management (RRM) and Self-Organizing Networks (SON) algorithms for enterprise and carrier Wi-Fi networks. He also provides guidance on planning and deployment of Wi-Fi networks. Prior to this, Dr. Akhtar worked at the Centre of Excellence in Wireless Technology (CEWiT), Chennai, India where his research focused on L2 and L3 aspects of Long-Term Evolution (LTE) systems, particularly on issues related to mobility management, resource allocation and interference coordination. He represented CEWiT at the 3GPP Radio Access Network standardization meetings for 5 consecutive years. Dr. Akhtar has authored/co-authored a significant number of publications in international conferences, magazines and journals, and has contributed to two books.

Dr. Nadeem Akhtar received his B.Sc. (Eng.) degree in Electronics from Aligarh Muslim University in 1998, followed by an M.E. in Telecommunications from the Indian Institute of Science in 2000. He obtained his Ph.D. from the University of Surrey (UK) in 2007.

Dr. Mahima Mehta is an LTE Systems Engineer at Intel Mobile Communications, Bangalore. Earlier, she had been an academician and researcher for more than 12 years. She worked as Research Scientist at IIT Bombay for about a year. She led the India-UK Advanced Technology Centre (IU-ATC) project funded by Department of Science and Technology (DST), and also contributed to the Department of Electronics and Information Technology (DietY) funded project on Dual Connectivity LTE WiFi Solution for Broadband Wireless Networks. Dr. Mehta represented the IIT Bombay at 3GPP RAN2 standardization meetings. Having served as a Technical Program Committee member at various IEEE conferences, she has authored/co-authored several research publications in reputed journals and national/international conferences.

Dr. Mehta received her B.E. degree in Electronics and Communication Engineering from Government Engineering College, Bhopal in 2001 and M.E. from Shri Govindram Seksaria Institute of Technology and Science (SGSITS) Indore in 2007. She was awarded her Ph.D. degree in Electrical Engineering from the Indian Institute of Technology (IIT) Bombay, Mumbai, India in 2014.
