Small cells handover performance in centralized heterogeneous network

Abstract

Before the full release of 5G, 4G will continue to be developed to support many new use cases and applications. By making some modifications and enhancements on its structure, 4G can handle many new features that could be seen as 5G specifics. Such enhancement includes the use of small cells in heterogeneous networks, mobile edge computing, and cloud computing, virtualizations and software-defined networks (SDN), and network slicing. Heterogeneous network supported by computing functionality is one of the most recent added flavor topologies to LTE technology and the upcoming next-generation mobile network. Mobility is yet one of the main challenges in such a system. Allowing the user to surf the world of the data without interruption while in the move between the different cells of the heterogeneous network in the future 5G network is required to keep the high level of the user’s quality of experience. In this paper, new mobility-enhanced schemes are presented for improving the handover performance of a mobile UE with dual connectivity in heterogeneous network.
