However, the complexities introduced by heterogeneous network architectures, dynamic radio conditions, and diverse application requirements pose significant challenges to many traditional mechanisms of wireless networks, among which handover. This paper addresses these challenges by delving into the potential for machine learning techniques to optimize handover in 5G networks. We review the latest state-of-the-art machine learning methodologies, focusing on their application across various stages of the handover process. By exploring the synergy between machine learning and handover optimization, this research provides valuable insights into the novel techniques aimed at ensuring robust connectivity and enhanced quality-of-service metrics in dynamic network environments.  \nKeywords: machine learning, 5G, handover, wireless networks  \n1. Introduction  \nIn the era of pervasive connectivity and massive data demands, the deployment of 5G networks and their evolution towards sixth-generation (6G) technologies marks a paradigm shift in wireless communication systems. These advancements promise unparalleled throughput, ultra-low latency, and massive device connectivity, enabling applications from the Internet of Things (IoT) to augmented reality (AR) and autonomous systems. However, the efficient management of network resources and seamless user mobility are crucial to achieving ambitious goals across heterogeneous wireless environments.  \nOne of the critical challenges in achieving seamless connectivity and maintaining Quality-of-Service (QoS) metrics in these dynamic network landscapes is the optimization of handover procedures. Handover (HO) refers to transferring an ongoing communication session from one cell to another as a mobile user traverses the coverage area.  \nTraditional HO mechanisms in cellular networks rely on predefined thresholds and HO decision policies based on signal strength, received signal quality, and other network parameters. However, with the advent of 5G, conventional HO strategies face new complexities arising from heterogeneous network (HetNet) architectures, dynamic radio conditions, and different application requirements. In this context, machine learning (ML) is a promising approach to enhance HO optimization by leveraging data-driven insights, adaptive decision-making, and predictive analytics.  \nThis paper presents the latest developments in ML techniques for HO optimization in 5G networks. We categorize and review the state-of-the-art ML methodologies employed across different stages of the HO process, including prediction of HO events, optimization of HO parameters, and intelligent HO decision-making.  \nThe remainder of the paper is organized as follows.  \nIn Section 2 we set the stage with an overview of the related surveys and reviews on state-of-the-art ML-based HO optimization methodologies. Then, Section 3 is dedicated to providing the reader with a concise yet comprehensive background to HO in wireless networks in general and in 5G.  \nBuilding upon this understanding, Section 4 critically examines the latest ML techniques for HO optimization. For each contribution discussed, we detail the adopted approach and present the claimed advantages. Lastly, Section 5 synthesizes our findings and contributions.  \n2.
