The book provides an in-depth exploration of Handover Parameters Optimization (HPO), a crucial aspect of Self-Optimization Networks (SONs) in advanced mobile communication systems like LTE-Advanced. HPO is vital for ensuring seamless connectivity as users transition between network cells. Inefficiently set handover parameters can lead to significant problems, including excessive handovers, frequent ping-pong effects, and Radio Link Failures (RLFs), all of which negatively impact network performance, user experience, and system reliability. The development of HPO algorithms has been shaped by the guidelines of the 3rd Generation Partnership Project (3GPP), offering a robust framework for research and innovation. While various algorithms have been proposed to enhance handover efficiency, they often struggle to address the complex and dynamic nature of diverse network environments and user mobility. Despite their contributions to improving system performance, these methods often fall short of delivering truly optimal solutions.
