Özet

Providing higher frequency and wider bandwidths for communication are significant benefits of 5G. On the other hand, it is required to deploy various systems to achieve the full potential of these benefits. Furthermore, the dramatic increase in mobile devices poses critical challenges to ensure these advantages. Thus, ultra-dense networking (UDN) has been proposed as a solution to enhance connectivity in 5G and beyond. However, when the complexity of this architecture is considered, additional challenges are also introduced. This study explores the impact of 5G UDN on mobility management, examining both the issues that UDN can mitigate and the new complexities it introduces. In addition, potential research directions are discussed to improve mobility management. The primary contribution of this study is to provide information on how UDN can collaborate with other 5G enabling technologies to improve mobility management in beyond 5G (B5G) networks.
