The term Heterogeneous networks (HetNets) refers to a wireless network connected with various types and sizes of small cells and macrocells deployed to overlap each other. HetNets have gained much attention due to better coverage, higher throughput, improved energy efficiency and greater QoS. HetNet is considered to be an essential building block for future mobile network generations. In HetNets, small cells can be deployed at homes, offices, large shopping malls, sport stadiums, airports and other crowded areas. These small cells consist of various types such as microcells, picocellsfemtocells, etc. The network deployment plan will be an ultra-dense HetNet for the future 5G and 6G mobile communication system so as to meet high data and coverage demands.

Ensuring a seamless connection during the mobility of various User Equipments (UEs) will be one of the major challenges facing the practical implementation of the Fifth Generation (5G) and Sixth Generation (5G) networks and beyond. Several key determinants will significantly contribute to numerous mobility challenges. One of the most important determinants is the use of millimeter waves (mm-waves) as it is characterized by high path loss. The inclusion of various types of small coverage Base Stations (BSs), such as Picocell, Femtocell and drone-based BSs is another challenge. Other issues include the use of Dual Connectivity (DC), Carrier Aggregation (CA), the massive growth of mobiles connections, network diversity, the emergence of connected drones (as BS or UE), ultra-dense network, inefficient optimization processes, central optimization operations, partial optimization, complex relation in optimization operations, and the use of inefficient handover decision algorithms. The relationship between these processes and diverse wireless technologies can cause growing concerns in relation to handover associated with mobility. The risk becomes critical with high mobility speed scenarios. Therefore, mobility issues and their determinants must be efficiently addressed. This Special session aims to focus on mobility management in 5G and 6G mobile networks. That include, the innovative, advanced, efficient, and smart handover techniques that have been introduced in 5G and 6G mobile networks. The Special session also highlights the main challenges facing UEs’ mobility as well as future research directions on mobility management in 5G and 6G mobile networks.
